Summary: Coenzyme Q10 (often called CoQ10) is a vitamin-like substance used in the treatment of a variety of disorders primarily related to cellular energy production, metabolism, and oxidative injury. Research shows coenzyme Q10 to be most promising for neurodegenerative disorders such as Parkinson’s disease and certain encephalomyopathies for which coenzyme Q10 has gained a high popularity.


Introduction

What is CoEnzyme Q10?

Coenzyme Q10 (2,3 dimethoxy-5 methyl-6-decaprenyl benzoquinone) is a fat-soluble, vitamin-like quinone commonly known as ubiquinone, CoQ, and vitamin Q10. It is available in more than 100 single-ingredient and combination-ingredient products, and in 2002 it accounted for more than $200 million in sales in the United States. [R]

Coenzyme Q10 was first isolated in 1957 in beef mitochondria, and is found in highest concentrations in tissues with high energy turnover such as the heart, brain, liver, and kidney.

CoQ10 is a ubiquitous compound vital to a number of activities related to energy metabolism.

Because dysfunctional energy metabolism has been cited as a contributing factor for a number of conditions, coenzyme Q10 has been indicated in the treatment of cardiac, neurologic, oncologic, and immunologic disorders.

Although the Dietary Supplement Health and Education Act of 1994 does not allow claims for treatment of specific diseases in the United States, coenzyme Q10 has been cleared for treatment indications in other countries, such as for congestive heart failure (CHF) in Japan since 1974.

“Coenzyme Q10 (also known as ubiquinone, ubidecarenone, coenzyme Q, and abbreviated at times to CoQ10, CoQ, or Q10) is a coenzyme that is ubiquitous in animals and most bacteria (hence the name ubiquinone). It is a 1,4-benzoquinone, where Q refers to the quinone chemical group and 10 refers to the number of isoprenyl chemical subunits in its tail.

This fat-soluble substance, which resembles a vitamin, is present in all respiring eukaryotic cells, primarily in the mitochondria. It is a component of the electron transport chain and participates in aerobic cellular respiration, which generates energy in the form of ATP. Ninety-five percent of the human body’s energy is generated this way. Therefore, those organs with the highest energy requirements, such as the heart, liver, and kidney, have the highest CoQ10 concentrations.

There are three redox states of CoQ10: fully oxidized (ubiquinone), semiquinone (ubisemiquinone), and fully reduced (ubiquinol). The capacity of this molecule to act as a two-electron carrier (moving between the quinone and quinol form) and a one-electron carrier (moving between the semiquinone and one of these other forms) is central to its role in the electron transport chain due to the iron–sulfur clusters that can only accept one electron at a time, and as a free-radical–scavenging antioxidant.” – Wikipedia

From Nootropics Depot:

Coenzyme Q10 (also known as CoQ10) is, as the name suggests, a coenzyme. CoQ10, via its action as a coenzyme, can drive many cellular processes throughout our bodies. Although not classified as a vitamin, CoQ10 closely resembles the structure of vitamin K and it appears that CoQ10 benefits resemble vitamin-like effects. This also hints at an important aspect of CoQ10: it is essential for overall human health. Without CoQ10, many bodily functions would may not work properly. Luckily our bodies are fairly good at preserving CoQ10, and CoQ10 deficiencies are rare. That said, taking a CoQ10 supplement still may have some remarkable effects on overall health.

Supplementing with extra Coenzyme Q10, alongside a healthy diet, may produce the following CoQ10 benefits:

  1. Coenzyme Q10 can support our cardiovascular health
  2. Coenzyme Q10 can support our metabolic function
  3. Coenzyme Q10 can promote our cognitive function
  4. Coenzyme Q10 can support brain health via its neuroprotective effects

A large majority of these CoQ10 benefits are attributed to how CoQ10 helps the body produce adenosine triphosphate (ATP), a very important molecule which drives most biological processes in the body. CoQ10 is also known as a redox molecule, which allows it to transfer between fully oxidized and fully reduced states. Through its redox actions, CoQ10 can help power our cells while also helping protect them from oxidative stress. This all sounds great on paper, right? However, CoQ10 in its crystalline form is faced with some major issues and may not be able to produce all of the CoQ10 benefits mentioned above.


Benefits & Effects

What Are The CoQ10 Benefits?

  1. Enhances and Sharpens Mental Capabilities
  2. Boosts Energy and Reduces Fatigue
  3. Boosts Mitochondrial Health & Function
  4. Reduces Stress and Free Radicals Damage
  5. Supports Fertility
  6. Combats Statin Drug Side Effects
  7. Cancer Prevention Potential
  8. Powerful Antioxidant & Neuroprotectant
  9. Protects Blood Vessels and Enhances Blood Flow

Supporting research:

Enhances and Sharpens Mental Capabilities

Coenzyme Q10 may also present significant benefits to your cognition. Studies found that individuals with higher levels of CoQ10 showed greater mental sharpness, increased mental energy, and greater performance on a variety of mental tests. In contrast, those with lower levels of Coenzyme Q10 had greater difficulty concentrating, experienced brain fog, were slower in their mental processing, and showed general cognitive decline. Some researchers suggest that taking Coenzyme Q10 early enough may decrease your chances of suffering memory loss as a result of aging.

Boosts Energy and Reduces Fatigue

Some studies also show that Coenzyme Q10 may help to reduce physical fatigue, increase energy, improve exercise capacity, and expedite recovery from exercise.

Boosts Mitochondrial Health & Function

In studies of eight to 44 patients, Coenzyme Q10 demonstrated positive trends in reducing symptoms associated with selected mitochondrial abnormalities including the mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) syndrome, Kearns-Sayre syndrome, and the myoclonus epilepsy with ragged-red fibers (MERRhF) syndrome. [R]

Reduces Stress and Free Radicals Damage

Oxidative damage (or free radical damage) of cell structures plays an important role in the functional declines that accompany aging and cause disease. As both a water- and fat-soluble antioxidant, CoQ10 has been found to inhibit lipid peroxidation, which occurs when cell membranes and low-density lipoproteins are exposed to oxidizing conditions that enter from outside the body. [R]

Supports Fertility

The antioxidant properties of CoQ10 could help improve sperm quality and reduce the decline in the number and quality of eggs in women. Supplementing with CoQ10 seems to help and may even reverse this age-related decline in egg quality and quantity.

Female fertility decreases with age due to a decline in the number and quality of available eggs. CoQ10 is directly involved in this process. As you age, CoQ10 production slows, making the body less effective at protecting the eggs from oxidative damage. [R]

Combats Statin Drug Side Effects

Statins are drugs that help lower cholesterol but often come along with a host of side effects.

Patients suffering from statin-related muscle pain, muscle strength degradation, and decreased aerobic activity can increase performance through daily intake of CoQ10 without other symptoms.

“Statin drugs can induce rhabdomyolysis (muscle death) which release rhabdomyosarcoma cells into the bloodstream, degrading other tissues. Human rhabdomyosarcoma cells treated with a CoQ10 supplement alongside simvastatin reversed muscle death and killed off remaining sarcoma cells.” [R]

Cancer Prevention Potential

Low levels of CoQ10 have been associated with up to a 53.3% higher risk of cancer and indicate a poor prognosis for various types of cancer [R]

CoQ10 plays a critical role in the protection of cell DNA and cell survival, both of which are strongly linked to cancer prevention and recurrence.

Powerful Antioxidant & Neuroprotectant

Antioxidants are necessary for neutralizing harmful compounds known as free radicals, which are created when cells undergo oxidation. Free radicals can promote cell death, mutate DNA, and damage cell membranes. CoQ10 may help to eliminate free radicals and prevent the damage they can cause. Some studies even suggest that CoQ10 may recharge other antioxidant compounds and nutrients.

Within mitochondria, coenzyme Q10 has been found to protect membrane proteins and DNA from the oxidative damage that accompanies lipid peroxidation and neutralize free radicals directly that contribute to nearly all age-related diseases (heart disease, cancer, diabetes, neurological disease, etc.). [R]

Protects Blood Vessels and Enhances Blood Flow

According to Nootropics Depot, one of the most popular companies that manufactures nootropics, CoQ10 can protect your blood vessels and enhance your blood flow. This is partly caused by preservation of nitric oxide, a signaling molecule that relaxes the arteries. This may improve overall circulation and cardiovascular health.

COQ10 can reduce the damage oxidized Low-density Lipoprotein (LDL) can do to blood vessels, as well as reduce plaque buildup in the arteries.


Mechanism of Action

How Does CoQ10 Work?

Coenzyme Q10 is vital for the proper transfer of electrons within the mitochondrial oxidative respiratory chain, whose main function is adenosine triphosphate production. Coenzyme Q10 also appears to increase adenosine triphosphate levels by preventing the loss of the adenine nucleotide pool from cardiac cells.4 Additionally, coenzyme Q10 has demonstrated activity in preventing lipid peroxidation as an antioxidant scavenger and an indirect stabilizer of calcium channels to decrease calcium overload.

Much of the basic research in support of coenzyme Q10 supplementation has focused on the CHF model. The myocardium of patients with CHF demonstrates increased oxidative stress as well as decreased concentrations of coenzyme Q10 as confirmed by tissue assays.8 These levels appear to correlate with CHF severity in the animal and human model, with coenzyme Q10 supplementation protecting against ischemia and reperfusion injury in animal studies.

Ubiquinol vs. Ubiquinone

Coenzyme Q10 can occur in multiple different forms in the body, and the two most abundant forms are oxidized CoQ10 (ubiquinone) and reduced CoQ10 (ubiquinol). Many people tend to prefer ubiquinol, due to its oxidation reducing effects in the body. However, due to this, the lesser desired ubiquinone often times gets overlooked. This is a shame because it actually has some very unique effects! Ubiquinone plays a major role in the electron transport chain, acting as a shuttle for cellular energy. Due to the fact that ubiquinone CoQ10 is hydrophobic and lipophilic, it can freely move between hydrophobic regions in the inner membranes of mitochondrion. It moves by way of passive diffusion, so no energy is needed to move CoQ10 around in the mitochondrion.

Ubiquinone stores energy temporarily, and is able to move it through the electron transport chain. It does this by attaching an electron to its benzoquinone head. It can accept electrons from various different systems, such as NADH-Q reductase. Ubiquinone transports these electrons from complex I and complex II of the electron transport chain, to complex III of the electron transport chain. While it does this, it also transports protons, which generates a proton gradient across the inner mitochondrial membrane. As these protons flow back across the inner mitochondrial membrane, it directly helps form adenosine triphosphate (ATP). This is in addition to ubiquinone already enhancing ATP synthesis by transporting electrons throughout the electron transport chain.

Nootropics Depot

What Does Ubiquinol Do?

As mentioned earlier, many people appear to prefer the fully reduced form of Coenzyme Q10, ubiquinol. Why is this the case? In the body, and especially in mitochondrion, ubiquinol benefits are focused on directly reducing oxidation. This is highly important in mitochondrion as their high activity results in large amounts of oxidative stress. By supplementing with ubiquinol CoQ10, it is possible to directly reduce oxidation in targeted areas such as the mitochondrion. These ubiquinol benefits make it highly attractive to consumers, and for good reason, as these oxidation reducing ubiquinol benefits are very desirable! That being said, you do not necessarily have to directly supplement with ubiquinol in order to utilize ubiquinol benefits. This is due to the fact that ubiquinone actually turns into ubiquinol as it travels through the electron transport chain. In the electron transport chain, CoQ10 exists in three forms: ubiquinone, semiquinone and ubiquinol. Ubiquinone is the fully oxidized form, and when it picks up a proton, it turns into the partially reduced form, semiquinone. Semiquinone is a highly unstable compound which is quickly further reduced to ubiquinol by picking up another proton. Ubiquinol may then act as an antioxidant in the mitochondria. However, when ubiquinol interacts with an oxidant, it becomes oxidized and loses a proton. This turns ubiquinol back into semiquinone. Semiquinone then also becomes oxidized and now we are back at the fully oxidized form of CoQ10: ubiquinone. This means that by either supplementing with ubiquinone or ubiquinol, you will reap similar benefits. That being said, supplementation of ubiquinone may act more rapidly to produce ATP whereas supplementation with ubiquinol may act more rapidly to control oxidative stress in the mitochondria. – ND

Dosage

How To Take CoQ10?

The standard dose for CoQ10 is generally 90mg for a low dose and 200mg for the higher dose, taken once daily with a meal due to its reliance on food for absorption.

There generally isn’t too much of a therapeutic effect of CoQ10 supplementation (mostly taken with the ‘just in case’ mentality that pervades multivitamin supplementation), although for people who have previously experience a heart attack or damage to cardiac tissue as well as for people on statin therapy supplementation becomes much more important. CoQ10 supplements can be either the oxidized form (ubiquinone) or reduced form (ubiquinol) as both forms seem pretty equally potent in increasing circulating levels of total CoQ10 in the body. ‘Total CoQ10’ refers to the sum of both forms, since CoQ10 can readily swap between forms as it acts in the body. – Examine.com


Frequently Asked Questions

What is CoQ10?

Coenzyme Q10 (CoQ10) is a natural antioxidant synthesized by the body, found in many foods, and available as a supplement. It comes in two forms: ubiquinol, the active antioxidant form, and ubiquinone, the oxidized form, which the body partially converts to ubiquinol. Many multi-ingredient supplements contain both forms of CoQ10. In general, coenzymes support enzymes in their various biochemical functions. CoQ10 is a vital participant in the chain of metabolic chemical reactions that generate energy within cells. It is found in every cell of the body (the name ubiquinone stems from its ubiquity), but is present in higher concentrations in organs with higher energy requirements such as the kidneys, liver, and heart. Many medical studies demonstrate CoQ10 benefits when taken as a supplement, most of which stem from its vital role in oxygen utilization and energy production, particularly in heart muscle cells.

Why is CoQ10 necessary?

Coenzyme Q10 is beneficial for heart health in many ways. It assists in maintaining the normal oxidative state of LDL cholesterol, helps assure circulatory health, and supports optimal functioning of the heart muscle. CoQ10 may also help support the health of vessel walls. In addition, Coenzyme Q10 may play a role in reducing the number and severity of migraine headaches, and improving sperm motility in men. Some research has indicated therapeutic value in high doses to slow the progression of Parkinson’s disease, but a 2011 study by the National Institute for Neurological Disease and Stroke found no benefit in slowing symptoms or neural degeneration. A few small clinical trials have indicated CoQ10 supplementation may help prevent and treat inflamed gums, a condition known as gingivitis.

What are the signs of a Coenzyme Q10 deficiency?

Studies in both animals and humans have associated significantly decreased levels of CoQ10 with a wide variety of diseases. Since this enzyme is found in high concentration in heart muscle cells, deficiency has been associated with cardiovascular problems including angina, arrhythmia, heart failure and high blood pressure. Problems with blood sugar regulation, gingival (gum) health, and stomach ulcers have also been associated with CoQ10 deficiency. Those who are taking statins to lower cholesterol are at particular risk for deficiency, because not only do statins reduce cholesterol levels, but they also block CoQ10 synthesis in the body. Low CoQ10 levels in patients on statins can contribute to the common side effects of statin therapy such as fatigue and aching joints and muscles.

How much, and what kind of Coenzyme Q10, does an adult need?

There is no official Daily Value recommendation, but its suggested at least 90 to 120 mg of supplemental CoQ10 for any adult taking statin medications and for those with a family history of heart problems, or who is at increased risk for cardiovascular disease. This dosage is also appropriate for otherwise healthy men and women as a preventive measure and to help maintain a healthy cardiovascular system. CoQ10 is fat-soluble, so take the supplement with a meal containing fat. Seek out the soft-gel ubiquinol form when taking CoQ10 as a standalone supplement, as this has greater antioxidant efficiency than the ubiquinone form.

Is COQ10 harmful?

Of course not! The coenzyme Q10 (CoQ10) is vital for human metabolism, and is best known for its roles in glucose and fatty acid conversion to ATP, the form of energy used to power most body functions and as a powerful antioxidant in cells, inhibiting lipid peroxidation in cell membranes, DNA and low-density lipoproteins (LDL). Studies show that when taken daily, CoQ10 supplements are capable of significantly reducing oxidative damage. Also note that CoQ10’s levels in skin decline with age, which may also make your skin more susceptible to oxidative damage. The key thing that impacts the effectiveness of CoQ10 supplements is that many of them have relatively poor bioavailability due to limited solubility. Thus, it is helpful to go for solubilized forms of CoQ10 which allow for 90-100 percent of dissolution, and which have been improved absorption.

Summary: Ginkgo biloba is the most commonly ingested herb for brain health. Research proves that its neuroprotective, improves memory, boosts cognitive function, to name a few of its diverse benefits.

Introduction

What is Ginkgo Biloba?

Ginkgo biloba derives from the family of medicinal plant  Ginkgoaceae – which is highly loved, appreciated, and respected traditional Chinese medicine. It is the last and only ‘ginkgoaceae’ plant still existing today. The rest of the family is said to have gone extinct, after nearly 190 million years of existence. [R]

Today, Ginkgo biloba (also known as Tebonin, Tanakan, Rökan, Maidenhair, and gingko) is the most widely used herb for cognitive function and brain health.

Moreover, it is one of the top 10 best selling dietary supplements in the whole world. [R]

Although more commonly used by older people, the wide variety of benefits it possesses make it appeal to people of all ages.

Ginkgo biloba, commonly known as ginkgo or gingko, also known as the maidenhair tree, is the only living species in the division Ginkgophyta, all others being extinct. It is found in fossils dating back 270 million years. Native to China, the tree is widely cultivated, and was cultivated early in human history. – Wikipedia


Benefits & Effects

What Are The Benefits of Ginkgo Biloba?

  • Improves Memory (Formation, Consolidation, and Recall)
  • Ginkgo Relieves Anxiety & Stress (Generalized Anxiety)
  • Ginkgo biloba Relieves Depression Symptoms
  • Ginkgo biloba Protects Mitochondrial Health and Supports Longevity
  • Provides Neuroprotection
  • Promotes Nerve Repair and Neurogenesis
  • Promotes Better Sleep Quality
  • Treats Sexual and Erectile Dysfunction

Supporting Research:

Improves Memory (Formation &Recall)

In a placebo-controlled, double-blind, randomized clinical trial of an extract of Ginkgo biloba for dementia running over the course of 52 weeks and involving 309 patients, it was concluded that it is “capable of stabilizing improving the cognitive performance and the social functioning of demented patients for 6 months to 1 year.” [R]

Relieves Anxiety & Stress (Generalized Anxiety)

In another randomized, double-blind, placebo-controlled clinical trial using ginkgo extract in patients with generalized anxiety disorder and ‘adjustment disorder with anxious mood’.

In this study, the results were “significantly superior to placebo on all secondary outcome measures. It was safe and well tolerated and may thus be of particular value in elderly patients with anxiety related to cognitive decline” [R]

Ginkgo biloba Relieves Depression Symptoms

Due to its ability of preserving serotonin and dopamine, as well as having strong protective and antioxidant effects, those 3 together allow ginkgo to provide an antidepressant effect. [R]

Protects Mitochondrial Health and Supports Longevity

Ginkgo biloba extract (EGb 761) prevents mitochondrial aging by protecting it against oxidative stress. The study suggests that on a rodents experiment, the extract ‘partially’ prevented changes due to oxidative damage [R] and that sounded good enough for me to reach out to my supplements cabinet for a 120mg dose.

Provides Neuroprotection

In a different rodent study where they were fed ginkgo biloba, a reduction in platelet activating factor (PAF) activity was noted. That reduction seems to be one of the leading mechanisms allowing ginkgo to have neuroprotective effects. [R]

Promotes Nerve Repair and Neurogenesis

Ginkgo (bilobalide) appears to promote neuronal proliferation with higher potency than Rolipram. Moreover, this can apply to all neurons of the central nervous system as well as the peripheral nervous system (PNS). In addition to the cognitive function effect, this also underlie its nerve repair benefits. [R]

Promotes Better Sleep Quality

240mg Egb-761 over four weeks to depressed persons currently on therapy (trimipramine) was able to improve sleep efficiency by reducing the frequency of waking and increasing non-REM sleep, although REM sleep was unaffected. [R]

Treats Sexual Dysfunction

Some sources indicate that ginkgo may treat sexual dysfunction, such as erectile dysfunction or low libido.

Ginkgo has the ability to improve blood levels of nitric oxide, which improves circulation via the dilation of blood vessels. [R]

As a result, ginkgo may also be useful for treating various symptoms of sexual dysfunction by improving blood flow to those areas of the body.

Some research has investigated using ginkgo to treat sexual dysfunction caused by the use of antidepressant drugs (SSRIs). Results indicated that ginkgo wasn’t any more effective than a placebo in these cases.

Additionally, there may be an interaction between ginkgo and SSRI medications, which could render them less effective.

One study evaluated the use of ginkgo to increase sexual desire and contentment in women who were concurrently undergoing sexual psychotherapy [R]

The combination of ginkgo and therapy were effective over a longer term compared to a placebo, but supplementing with ginkgo alone was not.
The rationale for using ginkgo to treat sexual dysfunction makes sense, but research does not support it at this time.


Mechanism of Action

How Does Ginkgo Biloba Work?

Absorption of oral supplementation allows for a 79% to 88% depending on the variant whether it is ginkgolide A, ginkgolide B, or bilabolide [R] which if you try to say out loud would sound in between funny and awkward.

Oral ingestion of ginkgo biloba is thought to increase dopamine concentration levels in the prefrontal cortex. Which is related to the flavonoids rather than terpenoids assuming anyone would care about that comparison. [R] – However, the fact that its neurotrophic and neuroprotective effects may actually be extending its effects to the dopaminergic neurons is sort of interesting. “The key benefits of Ginkgo originate in one’s circulatory system. The most popular and effective nootropics and smart drugs, typically have the ability to enhance circulation. Gingko supports the release of thromboxane A2 and prostacyclin. These help protect vessel walls, while blocking platelet formation. The end result is improved circulation in all major tissues and organs in the body.

Having excellent brain circulation is critical, because if circulation is poor, it can lead to severe imbalances. In more mild cases, individuals can experience headaches. In more severe cases, individuals could have a stroke. When you have good brain flow, these instances can be prevented.

This increased blood flow helps maintain healthy neural tissues. When neuron and synapse growth are supported, memory formation is enhanced. Gingko works by acting as an acetylcholinesterase inhibitor. This aids in the protection of acetylcholine levels. When all these effects are combined, they lead to greater neuroplasticity. This is the brain’s ability to adapt over time, which is key to mental power long-term.

While focusing on neurotransmitters, such as serotonin, dopamine, and norepinephrine, Gingko acts as a Monoamine Oxidase inhibitor. Since this chemical generally decreases the amount of these neurotransmitters, Gingko helps to boost mental energy, clarity, and focus (by elevating levels of serotonin, norepinephrine, and dopamine).”


Dosage

How to Take Ginkgo Biloba?

For its nootropic effect, the recommended dose is 120 to 240 mg, and to be taken 2 hours before the task or performance.

For neuroprotection and preventing cognitive degeneration, the recommended dose is 40 to 120mg, taken three times a day after food.

Ginkgo comes in various forms and seems to be most effective when taken in several doses throughout the day that total 120–240 mg.

Ginkgo Biloba Stack

Ginkgo biloba seems to synergize very well with another popular herb and one of my favorite nootropics, Panax Ginseng. The exact synergism isn’t really known or understood, but it is suggested that its synergy is especially effective and beneficial for memory formation and enhancement.

It also goes well with Phosphatidylserine. There are claims of Phosphatidylserine enhancing the efficacy of ginkgo biloba but the study on the subject lacked solid evidence therefore is irrelevant.

If you would like to boost the cognitive effects of Ginkgo, you should stack is with a choline-enhancing supplements. These are known as cholinergics, and include options such as Alpha GPC and Citicoline. By stacking with a choline supplement, you can amplify positive effects.


Side Effects

What Are Ginkgo Biloba Side Effects?

For most adults, the risk associated with taking ginkgo is relatively low, but there are cases in which ginkgo could cause serious harm. If you are allergic to plants that contain alkylphenols or taking certain medications, you should not take ginkgo. Possible side effects include:

  1. Nausea
  2. Diarrhea
  3. Dizziness
  4. Headaches
  5. Stomach pain

Those taking selective serotonin reuptake inhibitors (SSRI) as antidepressants should not take ginkgo as it inhibits monoamine oxidase, reducing the effectiveness of the medications.Combining the two may also increase the risk of a potentially fatal condition known as serotonin syndrome. Examples of SSRIs are Prozac, or fluoxetine, and sertraline, also known as Zoloft.


Conclusion

Ginkgo biloba has strong anti-inflammatory and antioxidant capacities and an ability to improve circulation.

Together, these characteristics have the potential to affect numerous body systems and diseases, although the science behind it still has some catching up to do.

While ginkgo has been used for centuries, it’s not completely understood how it works. Much of the available research is inconsistent or inconclusive, and it’s important to keep that in mind.

As with any herbal supplement, there are risks involved. Ginkgo could lead to serious health complications if you are allergic or taking certain medications.If you’re thinking of including ginkgo in your regimen, be sure to consult your doctor first.


Frequently Asked Questions

Does Ginkgo biloba work?

Ginkgo extract has proven benefits to elderly people. This ancient herb acts to enhance oxygen utilization and thus improves memory, concentration, and other mental faculties also to significantly improve long-distance vision and may reverse damage to the retina of the eye. Studies have also confirmed its value in the treatment of depression in elderly people. The ginkgo extract may provide relief for those who suffer from headaches, sinusitis, and vertigo. It may also help relieve chronic ringing in the ears known as tinnitus.

Healing properties:
Germany and France have run literally hundreds of studies on the leaf extract. These studies along with similar studies in America, have shown significant results. The extract of ginkgo biloba has been studied for its effectiveness in the treatment of acrocyanosis, Alzheimer’s disease, cerebral atherosclerosis, cerebral insufficiencies, cochlear deafness, dementia, depression, menopause, peripheral and cerebral circulatory stimulation, peripheral vascular disease, Raynaud’s syndrome, retinopathy, senility, short-term memory loss, tinnitus, vascular diseases, and vertigo. It is said to be effective in improving the blood flow to the hands and the feet as well as stimulating the brain and reducing short-term memory loss. It increases blood flow to the brain, the uptake of glucose by brain cells, and has been said to improve the transmission of nerve signals.

Depression:
Patients suffering from varying degrees of vascular insufficiency also noted an improvement in mood while taking ginkgo biloba extract. This has prompted a surge of interest in its use as a treatment for depression, especially in the elderly. Those under the age of fifty may also benefit from ginkgo biloba’s antidepressant effects. So far though, the greatest level of improvement has been noted with older patients.

Alzheimer’s & mental function:
As more than 300 studies demonstrate, ginkgo facilitates better blood flow through out the body, most notably the brain, where it both protects and promotes memory and mental function, even for people with Alzheimer’s disease.

Antioxidant Properties:
As an antioxidant, ginkgo biloba combats free radicals and repairs molecular damage. A great deal of research suggests that antioxidants such as GBE may play important roles in preventing or delaying heart disease, cancer and other ills. Antioxidants may even halt the damage to cells, thereby slowing the effects of aging.

Impotency:
Another use for ginkgo biloba is in the treatment of impotency. The main cause of male impotence is poor circulation and impaired blood flow through the penis, which is often the result of atherosclerosis. Since ginkgo biloba increases blood flow, it’s been found to help up to fifty percent of patients after six months of use.

Raynaud’s disease:
Raynaud’s disease is believed to be caused by blood vessels that over react to the cold and spasm, reducing blood flow and there by depriving extremities of oxygen. Ginkgo biloba may help this condition by widening the small blood vessels, which would keep these spasms from completely blocking the blood flow.

Parkinson’s Disease:
Ginkgo biloba may help symptoms by increasing the brain’s blood flow and thereby allowing more of the depleted dopamine to be circulated to the areas that need it most.

Other Conditions:
Other uses for which ginkgo biloba extract is often recommended include depression, diabetes related nerve damage and poor circulation, allergies, vertigo, short-term memory loss, headache, atherosclerosis, tinnitus, cochlear deafness, macular degeneration, diabetic retinopathy, and PMS.

Strokes:
Scientists continue to study the prevention and treatment benefits, ginkgo biloba may help stop strokes from occurring. It’s also believed that the herb inhibits free-radical damage of brain cells after a stroke.

Why is Ginkgo biloba called a living fossil?

You have to understand that Ginkgo biloba is the world’s oldest living plant. It is called a living fossil because it has no close living relatives and also appears to be the only plant species dating back 270 million years (Permian) in the fossil record. However, it is also one of a rare few (6%) dioecious flowering plants, meaning it has distinct male and female organisms. Not only has this exceptionally hardy species survived three mass extinction events over the past quarter of a billion years, but it was found to be the only surviving plant species near the epicenter of the August 6th, 1945 Hiroshima atomic bomb blast.

Does Ginkgo biloba actually enhance brain functions?

Yes. Scientific research support that it improves memory and cognitive thinking. But remember, just because it’s natural doesn’t mean it’s not harmful. Some people are allergic to Ginkgo biloba. They can also interfere with other medications, boasting or decreasing their effects. If you take other medications, always ask your physician if it’s safe to take a new one.

How much Ginkgo biloba is safe?

There is no standard dose of ginkgo. Most studies have used a standardized extract of ginkgo, to 24% flavone glycosides and 6% terpene lactones. For improving cognitive function, studies have used between 120 milligrams to 600 milligrams of the extract daily. The dose given to people with dementia is 40 milligrams of that extract three times daily. No matter why are you using ginkgo, you better start at a low dose (120 milligrams daily) and increase this level gradually while observing your body and its response to the supplement.

Introduction

What is Agmatine Sulfate?

Agmatine is a form of amino acid that derives from L-Arginine. It has been shown to inhibit receptors for the neurotransmitter acetylcholine, which plays a major role in memory and reasoning.

Agmatine supplement also regulates levels of Nitric Oxide by the affecting nitric oxide synthase enzyme. It controls cellular energy levels by influencing polyamine metabolism and function.

In some studies, it has been shown to enhance the effects of both morphine and fentanyl to increase pain killing, reduce tolerance, and lower addiction, as well as working synergistically with marijuana.

It is also found naturally in every day foods, including beer, wine, coffee, and other fermented foods.

Because it is capable of targeting multiple receptors, agmatine may benefit a spectrum of complex diseases, including diabetes, Alzheimer’s disease, opioid addiction, mood disorders, and even cancer. Furthermore, agmatine may enhance cognitive function, stress resiliency, mood, and athletic performance. The highest levels of agmatine are found in the gut, where it is produced by the microbes living there. It is also found in dietary form, mainly in fermented foods, and in supplemental form like agmatine sulfate. Agmatine is also produced in small amounts within the body by the mitochondria in the liver.

Supporting research:

Agmatine sulfate benefits the body and mind in many different ways and depending on the method it is taken. Some of the most notable agmatine benefits are:

Reduces Pain Sensitivity

In research studies, Agmatine shows to be an effective way for pain relief. Especially in the case of thermal hyperalgesia, a condition where the body is sensitive to changes in temperatures. The body becomes hypersensitive to heat or cold.

Agmatine improves those pain sensations, which is a result of its pro-circulations effect.

In studies looking at pain reduction in neuropathic conditions or inflammatory pain, agmatine was not found to produce a statistically significant effect. However, anecdotal, first-hand reports show that it actually did work for neuropathic conditions. So in this specific situation, it seems to be subjective to each individual.

Reduces Symptoms of Anxiety & Depression

Agmatine exhibits antidepressant effects and promotes mood improvement as well as anxiety reduction and relief. It helps the brain and body manage and overcome stress by reducing anxiety and promoting a sense of well-being.

By increasing NRF2, agmatine prevents depressive behavior by protecting brain cells from high levels of stress hormone cortisol. [R]

Agmatine increases adenylate cyclase in the prefrontal cortex, and decreases levels of adenylate cyclase which associate with depression. [R, R].

Furthermore, it blocks the NMDA receptor, prevents calcium overloading, as well as reverses the decrease of monoamines such as norepinephrine, epinephrine, and dopamine. Depression often associates with a reduction of monoamines in the brain [R, R]

Studies & Research

A small pilot study on three patients suffering depression, Agmatine supplement caused a complete disappearance of depression symptoms in all patients. It most likely did so through NMDA receptor-blocking and not through serotonin pathways. [R]

Agmatine also reduced anxiety in rats when they were put in swimming and maze navigation tests. [R]

Neuroprotection & Longevity

Agmatine acts as an anti-oxidant and is continuously under more research for its anti-aging and longevity potential. It has been found to exhibit neuroprotective effects against oxidative damage and injuries to the Central Nervous System (CNS). It is also believed to limit the activity of glutamate receptors and thus, the over-excitation of neurons within the brain.

Additionally, by inhibiting iNOS and nNOS and increasing eNOS, Agmatine protects against brain damage from stroke. Increasing eNOS protects the brain by dilating the blood vessels to increase blood flow. This prevents damage during times of lack of oxygen from reduced blood flow to the brain (also known as ischemic stroke).

Agmatine decreases iNOS and nNOS, two enzymes that contribute to brain damage from stroke. [R]

A Study on Effects of Agmatine Sulfate on Nerve Injury:
  • OBJECTIVE:
    Evaluate the effect of agmatine sulphate on facial nerve regeneration after facial nerve injury using electron and light microscopy.
  • METHODS:
    The study was performed on 30 male Wistar albino rats split into: a control group, a sham-treated group, a study control group, an anastomosis group, and an anastomosis plus agmatine sulphate treatment group. The mandibular branch of the facial nerve was dissected, and a piece was removed for histological and electron microscopic examination.
  • RESULTS:
    Regeneration was better in the anastomosis group than in the study control group. However, the best regeneration findings were seen in the agmatine sulphate treatment group. There was a significant difference between the agmatine group and the others in terms of median axon numbers (p < 0.004) and diameters (p < 0.004).
  • CONCLUSION:
    Agmatine sulphate treatment with anastomosis in traumatic facial paralysis may enhance nerve regeneration. PMID: 28122652

Improves Weight Loss & Prevents Weight Gain

Individuals who struggle to gain weight can benefit from Agmatine supplements. In some studies, subjects increased food consumption rates by 44% to 54% in 24 hours.

Moreover, in the following studies, Agmatine shows an increase in fat burning, a decrease in fat composition, and an increase in muscle mass [R], which also contributes to the next benefit of Agmatine:

Supports Muscle Growth

Agmatine stimulates the production of luteinizing hormone (LH). Increasing these hormone levels lead to an increase in testosterone levels.

By increasing testosterone levels, Agmatine contributes to an optimal hormonal environment for muscle growth, enhances athletic performance, and fastens recovery. [R]

Agmatine also increases insulin sensitivity and the uptake of glucose into the muscle. Increasing insulin sensitivity results in more effective shuttling of amino acids as well as glucose into the tissues for growth and repair. [R] [R]

Helps Erectile Dysfunction & Infertility

Studies show that L-arginine is involved in the process of cell replication, in addition to enhancing blood circulation, so it can help improve both sperm production and motility.

Men dealing with cardiovascular issues due to low levels of NO in the blood are more prone to experience erectile dysfunction and fertility problems because an erection requires a relaxation of smooth muscles, which Nitric Oxide triggers.

Although it doesn’t apply to every person, a significant rate of male infertility cases (92%) is treatable with L-arginine supplements in combination with dilators, antioxidants and/or anti-inflammatories. [R]

Research suggests that high-stress levels lower L-arginine levels in the sperm production pathway. Therefore, men with chronic stress specifically can benefit from Agmatine supplement.

According to Dr. Axe, a combination of L-arginine, L-glutamate and yohimbine hydrochloride is a common way of treating erectile dysfunction. And it works better than L-arginine alone. [R]

“In fact,” he says, “many of the most frequently prescribed medications for ED work similarly to L-arginine: by increasing nitric oxide production.”

Furthermore, there’s research suggesting treatment with N-Acetyl Cysteine (NAC) and L-arginine together can help balance hormones naturally and restore normal sexual function in women with polycystic ovary syndrome and estrogen imbalances.

Other studies suggest that L-arginine with herbs such as chasteberry, green tea extract, and antioxidant supplements improve pregnancy rates in women struggling to conceive. [R]

Help with Alzheimer’s Disease

Insulin resistance could cause an increase of plaque and neurofibrillary tangles in the brain, which are the signs of Alzheimer’s disease. Agmatine prevents cognitive decline by rescuing insulin signaling and avoiding potential accumulation of those tangles. [R]

Helps Alcohol & Morphine Withdrawal

Agmatine reduces and to an extent, prevents, symptoms of alcohol withdrawal such as “wet dog shakes,” anxiety, flashes, and shakings. [R] [R]

Mechanisms of Action

How Does Agmatine Sulfate Work?

Agmatine has several mechanisms. It can inhibit N-methyl-D-aspartate (NMDA) and nicotinic acetylcholine receptors, as well as activate imidazoline receptors. Agmatine can also inhibit nitric oxide synthase enzymes, which allows it to regulate elevated levels of nitric oxide. Agmatine can inhibit calcium channels and specific serotonin receptors as well. Further research is needed to determine the full extent of agmatine mechanisms. [R]

Agmatine was found to exert modulatory actions directly and indirectly at multiple key molecular targets underlying cellular control mechanisms of cardinal importance in health and disease. It is considered capable of exerting its modulatory actions simultaneously at multiple targets. The following outline indicates the categories of control mechanisms and identifies their molecular targets:

Neurotransmitter receptors and receptor ionophores. Nicotinic, imidazoline I1 and I2, α2-adrenergic, glutamate NMDAr, and serotonin 5-HT2A and 5HT-3 receptors. Ion channels. Including: ATP-sensitive K+ channels, voltage-gated Ca2+ channels, and acid-sensing ion channels (ASICs).

Membrane transporters. Agmatine specific-selective uptake sites, organic cation transporters (mostly OCT2 subtype), extraneuronal monoamine transporters (ENT), polyamine transporters, and mitochondrial agmatine specific-selective transport system. Nitric oxide (NO) synthesis modulation. Both differential inhibition and activation of NO synthase (NOS) isoforms is reported.

Polyamine metabolism. Agmatine is a precursor for polyamine synthesis, competitive inhibitor of polyamine transport, inducer of spermidine/spermine acetyltransferase (SSAT), and inducer of antizyme. Protein ADP-ribosylation. Inhibition of protein arginine ADP-ribosylation. Matrix metalloproteinases (MMPs). Indirect down-regulation of the enzymes MMP 2 and 9. Advanced glycation end product (AGE) formation. Direct blockade of AGEs formation. NADPH oxidase. Activation of the enzyme leading to H2O2 production.

Dosage

How to Take Agmatine Sulfate?

There is currently no standard dosage for agmatine sulfate because there haven’t been enough human studies for determination. These numbers are rough estimates to give an idea of typical, experimental dosing:

  1. For treatment of neuropathic pain: 1,000 to 2,500 mg of agmatine (daily)
  2. For improving cognitive function: 200 to 500 mg of agmatine (daily)
  3. For vasodilation and enhanced recovery: 500 to 1000 mg of agmatine (30 minutes pre-workout)

Note: Agmatine is not absorbed well when taken with dietary protein, because it uses the same transporters as arginine

Quoting Examine:

“There are no standard dosages for agmatine because of the lack of human evidence for its effects. However, a single human study used 1,300-2,670mg of agmatine, daily for the treatment of neuropathic pain. The estimated human dose for improving cognition is 1.6-6.4mg/kg of agmatine, taken orally.

This is based off of the 10-40mg/kg dosage range for rats, and is equivalent to 217-435 mg for a 150lb person. Supplementation should not exceed 6.4mg/kg of bodyweight. Studies on agmatine use a daily dosing protocol.

Agmatine is not absorbed well when taken with dietary protein, because it uses the same transporters as arginine. Further research is needed to determine if oral agmatine supplementation provides the same benefits as were observed in animal studies.”

“The generally accepted daily dosage range for Agmatine Sulfate is between 250 mg and 2.5 grams. Avoid taking higher than necessary dosages to reduce the risk of side effects.”


Side Effects

What Are Agmatine Sulfate Side Effects?

According to studies conducted so far, it appears that Agmatine Sulfate is safe even in relatively high doses. While there have been few studies conducted thus far, they have not shown any side effects to be associated with this supplement.

If you follow the recommended Agmatine sulfate dosage protocol and do not have any pre-existing contraindications for use, the risk of serious adverse effects is very low. Minor side effects included nausea, diarrhea, and vomiting in a small percentage of participants, which cleared up after a few days of discontinuing use. [R]


User Experiences

Agmatine Sulfate Reddit User Experience

“Not only does it have varied anti-addiction properties to Opioids, amphetamines, caffeine, nicotine & alcohol, but it also seems to make other drugs, and medicines more potent in their effects. It also shares the properties of Ketamine’s antidepressant effects, via the mTOR AMPA pathway. A small study found a robust antidepressant effect; all patients reported remission of depression. Considering that, shutting down Serotonin production via parachlorophenylalanine, did not reverse the antidepressant effects, shows how punchy this substance is. It’s also a painkiller. I’d recommend this be added to everyone’s stack, provided they aren’t too fond of Alcohol, as I noticed it definitely seems to blunt the good feelings of certain drugs.” Reddit user

Side Effects

What Are N-Acetyl Cysteine Side Effects?

N-Acetyl Cysteine is a safe substance with very few known side effects. Although occasionally, it can cause nausea, diarrhea, or constipation.

Large doses in a mouse model showed that acetylcysteine could potentially cause damage to the heart and lungs. They found that acetylcysteine was metabolized to S-nitroso-N acetylcysteine (SNOAC), which increased blood pressure in the lungs and right ventricle of the heart (pulmonary artery hypertension) in mice treated with acetylcysteine.

The effect was similar to that observed following a 3-week exposure to an oxygen-deprived environment (chronic hypoxia).

The authors also found that SNOAC induced a hypoxia-like response in the expression of several important genes both in vitro and in vivo.

User Experience

Both the reviews/experiences below are customer reviews posted on Nootropic Depot’s product page. You can only write a review for a product you actually purchased:

NAC is the supplement of choice for helping to mitigate nasal congestion. I’ve found even with a cold, taking a large dose divided up into several small doses separated by 2-4 hours throughout the day significantly controls the nose situation. Recently while going through this routine, I also noticed heightened mental clarity which quickly was attributed to the NAC as nothing else in my regular stack had changed. Combined with the fact the loose powder is inexpensive, NAC has high opinion from me. Con, it tastes terrible. It seriously tastes like butt if that was made from rubber. Capsulating it yourself is highly recommended!

NAC is an essential part of my daily routine. I take 2000mg every morning and if I feel a cold coming on I also take 1000 or 2000mg of an evening. Every winter I get a cold which precipitates a severe chest infection. It is now halfway through winter and I have not yet even caught a cold, despite the fact that the rest of my family has been sick with colds. My nose usually runs all winter but the mucous dissolving properties of NAC somehow even ameliorate that. I use Nootropics Depot’s NAC because I know it’s pure and independently tested. It comes in user friendly packaging, it’s inexpensive, the postage is tracked and it arrives quickly.

Frequently Asked Questions

What is N Acetyl L Cysteine Powder?

N Acetyl L Cysteine, also known as N Acetyl Cysteine or NAC, is an acetylated form of L Cysteine. NAC is one of few natural mucolytic agents. Mucolytic agents help thin out mucus which makes it easier to cough up mucus. NAC is also used to enhance the production of glutathione when it is normally depleted. Glutathione benefits are plentiful and thus, supplementing with NAC can provide many of the glutathione benefits we would see with glutathione supplementation.

What are N Acetyl L Cysteine Benefits?

Supports respiratory health
Promotes skin health
Supports organ health
Promotes vitality

What is N Acetyl L Cysteine Good For?

Studies observing glutathione levels after taking a NAC supplement found that NAC elevated glutathione levels. This is significant because the supplementation of glutathione on its own did not significantly increase glutathione levels. Since NAC is able to increase glutathione, NAC benefits have been linked to skin health, organ health, and promoting vitality. Additionally, taking a NAC supplement is believed to have some detoxification effects since it allows more glutathione to be produced. In addition, NAC benefits include organ protective properties when exposed to alcohol. A study on rats found that a NAC supplement taken 30 min before alcohol exposure seemed to produce a protective effect while administration 4 hrs after alcohol exposure elevated organ tissue damage. Additionally, these protective behaviors increased when alcohol consumption was stopped. Additional trials confirmed that the protective properties NAC has against alcohol only work when taken prior to alcohol consumption. Again, it is important to note that NAC should only be taken prior to consumption of moderate quantities of alcoholic drinks. NAC should never be taken after the consumption of alcoholic drinks as it may have an opposite and detrimental effect on the liver. This is important to note as many hangover supplements, intended to be taken after the consumption of alcoholic drinks, contain N Acetyl L Cysteine. The cystine-glutamate antiporter on astrocytes is known to regulate synaptic levels of glutamate by taking up cystine, the oxidized dimer form of Cysteine, in exchange for glutamate release. It is believed that additional Cysteine through N Acetyl L Cysteine supplementation may provide more substrate to further reduce glutaminergic stimulation. This is important, as glutamate can over-excite neurons, which can cause neuronal damage. This is part of the reason why some people avoid the consumption of monosodium glutamate, which is more commonly known as MSG. It is falsely believed that the consumption of MSG will result in too much glutamate in the brain, which could then cause neurotoxic effects. The claims that MSG has negative effects in the brain have long been disproven, however, glutamate levels may increase independently from MSG consumption. It is believed that higher Cysteine levels in the brain may lower glutaminergic transmission by lowering the amount of glutamate release. It has been found that glutamate levels can be reduced within 1 hour of orally administering a NAC supplement, making NAC a great neuroprotective agent. Other N Acetyl L Cysteine uses were studied after the relationship between glutathione and NAC supplementation were established. Researchers were interested in NAC for its vitality enhancing effects. Studies on sprint performance found vitality enhancing effect when subjects used a NAC supplement but only a slight increase in vitality from baseline was achieved with a large dose.

What Are N Acetyl Cysteine Food Sources?

The body converts N Acetyl L Cysteine which converts into Cysteine which is then converted to glutathione. Cysteine is an amino acid produced by the body but it requires methionine to do so. Cysteine is primarily found in animal proteins such as chicken, pork, sausage, turkey, fish and duck. Dairy sources of cysteine include yogurt, ricotta cheese, eggs, and cottage cheese. Cysteine is also found in some plant sources for vegetarians and vegans. Foods such as broccoli, red pepper, onion, granola and oat flakes are all good sources of Cysteine. Other sources include garlic, bananas, linseed, soy beans, and wheat germ. Low levels of Cysteine can delay growth in children and lower immunity. Weakness and muscle loss may also occur as a result of a low Cysteine die

How much N Acetyl Cysteine should I take?

As a dietary supplement, take one 500mg of N-Acetyl L-Cysteine once daily.

Where to buy N Acetyl Cysteine Powder?


Nootropics Depot offers 200 gram, 400 gram and 1 kilogram jars of high quality N-Acetyl L-Cysteine powder. Nootropics Depot’s N-Acetyl L-Cysteine has been lab-tested and verified for both product purity and identity.

Summary: Vinpocetine is a neuroprotective nootropic, an extraction from flower-plant vinca minor. It works as a cognitive enhancer, memory booster, while also uplifting mood and supporting overall well-being.

Vinpocetine benefits
Vinpocetine Skeletal Structure

Introduction

What is Vinpocetine?

Vinpocetine (aka Cavinton, Intelctol), is an extract from flowering plant vinca minor (or myrtle); a flower-family native to Portugal, France, and other parts of central and southern Europe. A 1975 discovery by Hungarian chemist named Csaba Szantay. Only three years after the invention, production of the extract in pill form started. Some of the primary uses of Vinpocetine as a nootropic are memory and cognition improvement, increasing learning capacity, and mood enhancement. Medical applications extend to the treatment of cerebrovascular disorders, dementia, and strokes. It is very safe and has (almost) no side effects. Its excellent safety profile is inspiring more companies to study and research Vinpocetine to explore other possible therapeutic and nootropic benefits. Although less popular comparing to other nootropics, the research as well as the knowledge of it is rapidly growing


Benefits & Effects

What Are Vinpocetine Benefits?

  1. Improves Memory and Cognition
  2. Increases Focus, Concentration, and Brain Blood Flow
  3. Enhances Learning Capacity, Information Processing, and Attention
  4. Reduces Cognitive Decline and Increases Overall Well-Being
  5. Neuroprotective and Anti-Inflammatory

Supporting research:

Vinpocetine Improves Memory and Cognition

Vinpocetine is widely in use for memory improvement. In Eastern Europe, it is a medical prescription for treating memory-related problems and disorders. Clinical trials confirm its effect on improving memory formation, and individuals receiving Vinpocetine report it’s beneficial especially in remembering and recalling information. Other studies also confirm it as a memory enhancer that can be used by anyone looking to improve their memory. (R)

Increases Focus, Concentration, and Brain Blood Flow

Vinpocetine increases cerebral blood flow and supports better blood circulation without having adverse effects on blood pressure. The better blood flow and circulation leads to an increase in productivity within the brain. This productivity increases and allows for better focus and concentration, as well as allowing for longer and steady attention span. Take notes, fellow ADHD ADHE’s – (attention-deficit hyperactive extraordinary). (R) (R)

Enhances Learning Capacity, Information Processing, and Attention

Vinpocetine improves the body’s ability of converting dietary glucose and fat to ATP, which is the coenzyme that transmits chemical energy for metabolism. Having more ATP ready for use in the brain leads to better intellectual capability, and thereby learning becomes more comfortable and faster. Moreover, the presence of sufficient ATP reduces feelings of mental exhaustion and “brain fog,” as well as supports feelings of mental clarity. (R)

Reduces Cognitive Decline and Increases Overall Well-Being

An increase in overall well-being is a result of a reduction in the rate of cognitive decline. (R) (R)

Neuroprotective and Anti-Inflammatory

Vinpocetine also acts as an anti-inflammation agent in the brain. It reduces expression of the pro-inflammation and vascular cell adhesion molecules which can lead to neuronal death in some conditions (such as Alzheimer’s and Parkinson’s). The anti-inflammatory qualities of vinpocetine make it a promising neuroprotectant that is likely to have significant anti-aging and longevity benefits.


Mechanism of Action

How Does Vinpocetine Work?

Early studies show that Vinpocetine benefits the brain in many ways, one of which is by improving blood flow, circulation, and utilization of oxygen. Unlike common stimulants, Vinpocetine increases blood flow in the brain without affecting the rest of the body. It targets impaired cells and areas of poor circulation within the brain. Enhancing blood flow, circulation, and oxygenation allows the brain to tolerate conditions of lack of sufficient oxygen (such as ischemia and hypoxia) better. Those conditions can relate to strokes and similar injuries. The elevation of blood flow and oxygenation result the nootropic effect.

Furthermore, improving circulation and oxygenation in the brain also enhances the overall brain function while increasing the production of ATP. All of which are vital for cerebral metabolism. By generating sufficient amounts of ATP, vinpocetine increases the use of glucose thereby improves mental clarity.

Vinpocetine interacts with sodium, calcium, and potassium ion channels within the brain, modulating the release of various neurotransmitters. That includes, but not limited to acetylcholine, noradrenaline, serotonin, and dopamine. Increasing the availability of those neurotransmitters not only affects memory and overall cognition but may also improve mood by relieving feelings of anxiety and enhancing energy and well-being. Vinpocetine also acts as an anti-inflammation agent in the brain. It reduces expression of the pro-inflammation and vascular cell adhesion molecules which can lead to neuronal death in some conditions (such as Alzheimer’s and Parkinson’s). The anti-inflammatory qualities of vinpocetine make it a promising neuroprotectant that is likely to have significant anti-aging and longevity benefits.


Dosage

How To Take Vinpocetine?

For general health and prevention purposes, the low dose is 5mg 3x per day at meals and ranges up to 20 mg 3x per day. These doses are for neuroprotection, enhancing cerebral blood flow, and reducing the rate of cognitive decline.

For nootropic purposes, suggestion doses of 30 to 45 mg, 3 times a day, alongside food.


Side Effects

What Are Vinpocetine Side Effects?

Vinpocetine is very safe and has (almost) no side effects. It is also very well tolerated and has no reported adverse effects. New users rarely experience a soft version of caffeine “buzz” that fades away as tolerance to vinpocetine is increased. Keep in mind that increasing the daily dosage to over 40 mg could decrease benefits.

Introduction

What is Bacopa Monnieri?

Bacopa monnieri (also known as Brahmi) is one of the most acknowledged and widely respected nootropics. A traditional Ayurvedic medicine that has a good reputation of being a potent cognitive enhancer, stress and anxiety reliever, and brain protector. It improves memory formation and recall speed, it stimulates learning, enhances thought clarity, and increase brain function. It acts as a brain protectant, and studies confirm it as a potential remedy for dementia and similar conditions. Furthermore, it reduces anxiety and provides a feeling of calm and tranquility, all while eliminating stress. Users report it an excellent relaxant that improves sleep quality, leading to rejuvenating and refreshing rest. Its nootropic effects are comparable to those of Piracetam, one of the most popular smart drugs in the world. The supplement is produced from the plant extracts.

Improves Learning and Cognition

Bacopa Monnieri improves cognitive processing, making learning new things faster and easier. Studies show that it significantly enhances spatial learning, and it has also been confirmed to improve learning capacity in subjects under stress. Most users say that taking bacopa while studying makes it easier to understand and process new information. Reports carried out by clinical trials at India’s Central Drug Institute (CDRI) in Lucknow state that children taking bacopa show improved academic skills.[2]

Reduces Anxiety and Stress

Bacopa Monnieri is effective in reducing anxiety and stress. Clinical trials show that it significantly decreases anxiety and depression in volunteers, and animal studies compare bacopa to other plant extracts for the effective treatment of anxiety and similar disorders. [3] [4]

Neuroprotective and Promotes Longevity (Anti-Aging)

Bacopa is effective in reducing oxidative stress effects on the brain. It possesses potent antioxidant properties that protect the brain against environmental stressors associated in the cognitive decline relating to aging and associated with Alzheimer’s and other neurological diseases.[5]

Reduces Symptoms of Depression

In a study of individuals over 65 years old receiving 300mg dosage, the results show a notable decrease in depression symptoms as well as anxiety. [6]

Bacopa Monnieri waterhyssop
Bacopa is a genus of 70–100 aquatic plants belonging to the family Plantaginaceae. It is commonly known as water hyssop.

Mechanism of Action

How Does Bacopa Monnieri Work?

Bacopa’s nootropic and anxiolytic effects are due to its capability of enhancing neural communication as well as modulating the release of several neurotransmitters such as dopamine, serotonin, and GABA.

Memory and Cognitive

Although it works over time by a variety of functions, bacopa improves memory and cognitive abilities by increasing synaptic communication. It promotes dendrites generation, thereby enhancing neural signaling. The improvement in neural impulse transmission is key to cognitive enhancement. The active ingredient in Bacopa monnieri extract (Bacoside-A) has been shown to stimulate nerve cells and cause synapses to be more receptive to nerve impulses. Studies show that Bacoside-A can prevent dopamine receptor dysfunction. Dopamine is a powerful neurotransmitter responsible for the brain’s reward and pleasure systems.

It also improves production of the enzyme Tryptophan Hydroxylase (TPH2); vital to many central nervous system actions such as the biosynthesis of serotonin. Furthermore, Bacopa stimulates activity in the hippocampus by increasing the activity of kinases, which are proteins that regulate cellular pathways. Because the hippocampus is involved in almost all cognitive activity, this is one of the main methods that allows bacopa to boost brain function.

Anxiety and Stress Relief

Bacopa monnieri produces its unique calming effects through several actions. One of the most crucial anxiety reduction effects is within its power to modulate the activity of certain neurotransmitters like those that regulate the uptake of serotonin, which is connecting to mood and anxiety.

Another active ingredient in bacopa is hersaponin, an alkaloid that provides a relaxing and soothing effect. Bacopa’s active ingredients also support the activity of GABA, another major neurotransmitter that acts to prevent anxiety by restricting the signaling of neuron over-excitement due to stress.

Dosage

How To Take Bacopa Monnieri?

The minimum effective dose of Bacopa Monnieri is 300mg, taken with food or fat source. Some people, myself included, find it more effective at a higher dosage.

I take 300 to 600mg depending on the purpose, while people like Dave Asprey recommend a daily dose of 750mg.

Side Effects

What Are Bacopa Monnieri Side Effects?

Bacopa monnieri side effects are uncommon. It is generally safe and effective, nevertheless, side effects can occur just as with any other nootropic.

Bacopa side effects range from minor (digestion issues and fatigue) to severe (thyroid disorders and urinary tract complications). Minor side effects usually disappear as the body adapts to the herb.

Rodent studies suggest bacopa may reduce sperm count, so it’s wise to avoid it if you are planning to conceive. However, it didn’t have any impact on sex drive nor testosterone. Moreover, sperm count returns to normal once supplementation stops. [7]

Severe side effects may include thyroid disorders, urinary tract problems, gastrointestinal blockage, adverse impact on ulcers and lung conditions, and bradycardia.

So start with the lowest effective dose, and observe your body’s reaction to it. If adverse effects occur, stop use.

Conclusion

Bacopa monnieri enhances cognitive abilities, reduces anxiety, and treats a variety of conditions. Although it works over time, the anxiety-relieving effects are immediate.

Its a precious addition to nootropic stacks. If you’re looking for a natural nootropic to boost your cognition, relieve anxiety, and protect your brain against oxidative stress, Bacopa would make an excellent choice.

Summary: Acetyl-L-Carnitine is a popular multi-functional nutrient, amino acid type nootropic. It benefits the body and brain. A potent antioxidant and neuroprotectant, and a powerful energizing nootropic that promotes anti-aging and longevity.

Acetyl L-Carnitine

Introduction

What is Acetyl L-Carnitine?

Acetyl-L-Carnitine, also known as ALCAR and ALC, is an amino acid naturally produced in your body to generate energy. It’s also found in animal proteins such as red meats. Many people supplement with acetyl-L-carnitine because of its potential benefits. Acetyl-L-Carnitine is a more bioavailable form of amino acid l-carnitine, a derivative of amino acid lysine. The body continuously produces L-carnitine, and furthermore gets it from the foods you eat.

Although research shows actual carnitine insufficiency is uncommon in healthy people with no metabolic disorders, supplementation with addition of it is proven to be beneficial in many different ways. Ranging from improving heart health [1] to enhancing brain function. [2]

Acetyl-L-Carnitine is L-carnitine with the addition of an acetyl group, thereby making it the most bioavailable form of L-carnitine and it readily crosses the blood-brain barrier. Its primary actions work towards brain functionality. Its nootropic properties seem to magnify when taken with other nootropics. The combination makes it a potentiating agent allowing nootropics to work more effectively.

Other forms of L-carnitine include L-carnitine L-tartrate (LCLT) which is typically assessing physical performance, and Glycine Propionyl L-carnitine (GPLC), which relieves blood flow issues. The only L-carnitine form that possesses nootropic properties is Acetyl L-carnitine, and it furthermore provides both L-carnitine and acetyl groups (molecule) that act towards the development of the learning neurotransmitter, acetylcholine.

From Nootropics Depot product description:

What Is Acetyl L-Carnitine?

Acetyl L-Carnitine, also commonly known as ALCAR, is an acetylated version of L-Carnitine. L-Carnitine is an amino acid naturally produced but is also taken in supplement form. It is a natural nootropic supplement that may aid in delivering fatty acids to our cells’ mitochondria to be broken down. Acetyl L-Carnitine has superior absorption in comparison to standard L-Carnitine. Acetyl L-Carnitine promotes energy.

Acetyl L-Carnitine HCL Capsules are best known for supporting brain health and cognitive function, but it has many other potential uses.


Benefits & Effects

What Are Acetyl-L-Carnitine Benefits?

  1. Enhances Brain Function and Stamina
  2. Provides Neuroprotection Against Brain Cell Death
  3. Restores Cognitive Function and Repairs Impairment
  4. Support Mitochondrial Function and Nervous System
  5. Regulates Sexual Infertility and Erectile Dysfunction

Supporting research:

Research proves ALCAR beneficial to the brain and body in many ways. From enhancing cognitive abilities [3] to increasing energy [4], reducing pain, and even preventing damage from alcohol consumption. [5]

Enhances Brain Function and Stamina

Studies show that it successfully lowers mental exhaustion and improves cognitive function as well as learning capability. In a placebo-controlled, randomized, double-blind, 2-phase study, 66 participants with fatigue were given 2 g of L-carnitine once a day. By the end of the study, the group taking L-carnitine showed significant improvements in physical fatigue, mental fatigue, fatigue severity amongst other physical enhancements, as compared to those receiving a placebo.

Moreover, the study confirms that oral supplementation of L-carnitine reduces the total of fat mass, increases muscular mass, increases capacity for physical and cognitive activity, improves cognitive functions, all while reducing fatigue as well. [6]

Provides Neuroprotection Against Brain Cell Death

Due to its potent antioxidant attributes, ALCAR acts as a neuroprotectant, blocking and restoring damage from free radicals that injure brain cells. It also helps the brain clear itself of other toxins and decreases cell death due to excitotoxicity, a neurotic process that triggers by the over-activation of glutamate receptors. It enhances the neural network by stimulating nerves and signal receptors and additionally protects the brain against the damaging influences of drinking alcohol. [7]

Restores Cognitive Function and Repairs Impairment

One of Acetyl-L-Carnitine’ many exciting prospects is as a treatment for age-related neurological disorders, including Alzheimer’s disease. It has been confirmed to dramatically slow decline in Alzheimer’s patients and decreases age-related recall failure. Other studies showed that ALCAR supports repair ambulatory capability in the elderly and functions as a mood lifter as well as working as an anti-depressant in the elderly. [8]

Support Mitochondrial Function and Nervous System

ALCAR promotes mitochondrial function and serves to support the nervous system overall performance. Especially in the case where an individual is subject to neurodegenerative disease. It can be of significant benefit to people with physical disorders typically correlated with aging, including high blood pressure, diabetes, and metabolic syndrome. It has shown to be efficient in managing nerve pain, enhancing kidney function, and improving heart health. [9] [10]

Regulates Sexual Infertility and Erectile Dysfunction

ALCAR regulates men’s infertility and improves signs of andropause and erectile dysfunction. It is also in use to fight Peyronie’s disease, an inflammatory disease that affects the penis. [11] [12]

Additionally, it is under clinical trials as a possible treatment for chronic fatigue.


Mechanism of Action

How Does Acetyl-L-Carnitine Work?

ALCAR synthesizes primarily in the liver and kidneys, after which it travels to other tissues. ALCAR has excellent bioavailability. The gastrointestinal tract quickly digests it. Its actions differ considerably from other forms of L-carnitine, which don’t cross the blood-brain barrier. The acetyl groups that make ALCAR unique, enable it to cross the blood-brain barrier readily and rapidly. Its most effective role is within the cerebellum.

alcar
Acetyl-l-carnitine skeletal structure

Another one of ALCAR’s nootropic benefits involves the acetyl groups, which produce the support for the synthesis of the neurotransmitter acetylcholine. Often referred to as “the learning neurotransmitter,” acetylcholine is accountable for learning, memory, and cognitive function. Increased levels of acetylcholine result in an improvement in cognitive function, and low levels of that essential neurotransmitter risks neurological complications similar to Parkinson’s and Alzheimer’s.

Acetyl-L-Carnitine on Neurotransmitters

ALCAR resumes showing increasing levels of norepinephrine and serotonin. They are vital neurotransmitters that play an essential part in mood and brain function. The capacity to improve neurotransmitter production is one of the principal techniques that ALCAR complements nootropics attributes. Similar to those of the racetams, which enhance the action of neurotransmitter receptors in the cerebellum.

Moreover, ALCAR targets brain metabolism, promoting cellular energy and serving as a potent neuroprotectant. Its critical antioxidant qualities combat the impressions of cellular oxidation. It further decreases the number of damaged cells in an individual brain, thereby becoming a useful longevity tool.

Damaged fat cells identified as lipofuscin (age spots) also happen in the brain and are actively correlated amidst age-related neurological dysfunctions, lack of energy, and weak memory. By supporting the brain excrete those damaged cells. ALCAR increases brain function and significantly lessens the risk of neurodegenerative disorders. It has also been shown to limit brain deterioration during times of stress.


Dosage

How to Take Acetyl-L-Carnitine?

Typical ALCAR dosage is 500 mg per day once in the morning, and up to 1,500 mg split into three doses of 500 mg. From there, adjust dosage to your need without exceeding 1,500 mg. At least not during trial period. It is water-soluble, therefore it can be taken with or without food. However, taking ALCAR late in the evening can result in disruption of sleep.

Recommended ALCAR dosage, active amounts, other details:

“The standard dose for L-carnitine is between 500-2,000mg. There are various forms of carnitine supplementation available.Acetyl-L-Carnitine (ALCAR) is used for cognitive enhancement. L-Carnitine L-Tartrate (LCLT) is typically used for physical performance and power output. Glycine Propionyl L-Carnitine (GPLC) is used to alleviate intermittent claudication and blood flow issues. L-carnitine is supplemented daily. The equivalent dosage range for other forms of L-carnitine are as follows: 630-2,500mg (ALCAR), 1,000-4,000mg (LCLT) and 1,000-4,000mg (GPLC).”

Side Effects

What Are Acetyl-L-Carnitine Side Effects?

  1. Side effects are uncommon. If they occur, it is usually in in the cases of consuming high doses before allowing the body to adapt to the additional amount of Acetyl-L-Carnitine that it is receiving.
  2. Nausea is the most common side effect. It is easily preventable by taking ALCAR alongside food rather than on an empty stomach.
  3. Headaches are the second most common side effect, which may imply an excessive amounts of choline.
  4. Users report that headaches from ALCAR use decrease when they reduce the amount of choline in their stacks and diets.

User Experiences

A few shared user experiences from Reddit community users:

To be fair in sharing the Reddit community experiences, I will add the first 3 that I see whether the experience is positive or negative. Three Acetyl-L-Carnitine reddit experiences:

First reddit user experience:

As the title says, it’s been a game changer. Old stack was: Citicoline 300mg b.id with centrophenoxine 350mg one to two times daily. Switched Centro to ALCAR 500 one daily just to try and damn it’s been really good. Mornings are good, everything is really clear. Honestly this feels a lot like amphetamine. So much so that I cancelled my pdoc appt to get a refill. I was basically off the meds but wanted to have a few around but now I really don’t think I need them. Very glad people on here have posted about alcar before! – skibenz

Second user experience also from reddit:

Funny enough I get a stronger response from ALCAR then I do racetams in regards to mental performance. It seems to make me really smart. Your mileage may vary though. To OP: I get results in a day. Be careful for not overdoing it. I’ve posted before that acetylcholine overload tends to make you depressed and function worse. – eastmangobo

Third and quite an insightful one:

“I have been taking Acetyl for about 17 years. For the last 2 yrs or so it has affected me less and less (no idea why) but before that, I noticed a MASSIVE positive boost from taking it. I experienced a huge uptick in word retrieval and overall brain function. used to always say that when I took Acetyl, it was like an electric switch was turned on, as that’s what it felt like … electric..I always bought it in bulk powder and almost always used 1 gram in my morning shake (180lb Male). DO NOT use it after noon …. you will NOT sleep !!!! You should notice a difference within 3-4 days. As I did mention, I am noticing now that I am affected by Acetyl less and less. If I miss a few days, I don’t really notice it like I did years ago and I don’t really get that electric charge feeling. I don’t know why this is, as I’ve purchased a few different brands.” Gernan_Mafia

Conclusion

ALCAR is an outstanding amino acid nootropic. It offers many benefits to both the body and the brain. In addition to its potent  brain boosting effect, it is also a healthy nutrient. Acetyl-L-Carnitine is safe, affordable, very tolerable, and easily accessible in department and drug stores. It enhances cognitive function, supports ant-aging and longevity, which makes it a nootropic worth adding to any stack.

Frequently Asked Questions

What is the difference between L-Carnitine L-Tartrate, L-Carnitine Tartrate, and Acetyl L-Carnitine?

L-Carnitine L-Tartrate and L-Carnitine Tartrate are the same thing, they just truncate the L-Tartrate for brevity. This is the form of L-Carnitine that is in supplements that some studies have linked to possibly helping recover times from work outs (specifically it was shown that people taking L-carnitine had less damage to their leg muscles after a workout versus people that weren’t taking it), there weren’t any other observations of it’s added use outside of that.
Acetylcarnitine is an alternative form of l-carnitine for supplementation that has been pushed because of it’s bioavailability. The downside is that it’s less concentrated in the bloodstream after digestion. It doesn’t appear that any studies have been performed linking acetylcarnitine to exercise performance, but it’s only proven use has been in increasing sperm mobility. A few proposals have set out to use it treat neurological conditions, but none have yet been proven.

Can I take 5-HTP and Acetyl L-Carnitine together?

To date there has been no evidence that either counteract the other or have negative effects. Both substances are great for many aspects of brain health. You can be pretty safe in the assumption that it’s worth testing out for yourself to see how you react to this combination.

Can I take acetyl-l-carnitine & taurine together with antidepressants, antipsychotics and NAC?

They don’t interact, in fact, Acetyl-L-Carnitine is used as “complementary” therapy along with Psych Meds. Taurine is as well. Taurine is also VERY much so present in Energy Drinks like Red Bull & Monster. It is responsible for much of the “kick” and focus Energy Drinks give us.

Summary: Alpha-GPC is a natural choline compound. It works on its own as a powerful memory booster. In combination with other nootropics, it works as a potentiator boosting cognitive capabilities. It’s also used as a milt stimulant to boost energy and power output when exercising. Furthermore, it promotes cell regeneration and acts as a neuroprotective agent, against cognitive decline.

Alpha-GPC TTS Video on Youtube

Introduction

What is Alpha-GPC?

Alpha-GPC is a cholinergic compound naturally present in the body in small amounts and commercially manufactured as an extract of purified soy lecithin. [1]

Although there are dietary resources of Alpha-GPC such as dairy products, organ meats, and wheat germ, concentrations achieved by dietary intake are lower than those obtainable by a supplement. It works rapidly and reliably by delivering necessary choline to the brain. [2]

It provides valuable nootropic qualities, including memory enhancement and protection against brain aging, attributing to longevity. Clinical trials covering thousands of participants confirm Alpha-GPC is a remarkable remedy for memory loss that accompanies Alzheimer’s disease [3], vascular dementia [4], and stroke. [5]

Moreover, it provides neuroprotective, anti-aging benefits. Studies further suggest it is useful in the treatment of generalized anxiety. [6] [7]

Another benefit is its ability to enhance cells membrane health and promote rapid recovery following physical activity. Studies indicate that it also acts as a dopaminergic, encouraging the release of dopamine, meaning it works as a potential treatment for neurodegenerative diseases such as Parkinson’s, in addition to being an overall mood enhancer. [8] [9]

Potent Potentiator

However, many consider the real strengths of Alpha-GPC is the potentiating feature when in combination with other nootropics. The choline that it provides the brain with significantly magnify the cognitive enhancing effects of other nootropics, especially the racetams.

I’ve always liked both Alpha-GPC and Citicoline and appreciated their profound effect, until one day I added Aniracetam 750mg and it was as if I had just took a racetam for the first time. The effects of both nootropics synergize together so well, a year later both of them are on the front line among my nootropic stack.

Alpha-GPC vs Other Choline Sources

According to examine and based on a handful of different studies, Alpha-GPC appears to be the best currently known cholinergic in increasing plasma and brain choline levels, as it has better transportation into the brain than does choline (somewhat similar to CDP-choline) but since it is a greater percentage choline by weight (relative to CDP-choline) taking X dose of either drug gives more choline when using Alpha-GPC

Benefits & Effects

What Are Alpha-GPC Benefits?

  1. Improves Memory Formation and Recall
  2. Neuroprotection and Development of New Brain Cells
  3. Increases Energy and Speeds up Recovery
  4. Increases Attention and Enhances Mood

Supporting Research:

Improves Memory Formation and Recall

This effect is mainly due to the increase of choline it makes available for conversion to acetylcholine, which is profoundly correlating with cognitive functions and the ability to create and revive memories. Studies confirm it an effective treatment for memory impairment caused by age-related diseases, including Alzheimer’s and several forms of dementia. It has further proven to be capable of recovering memory in volunteers following brief chemically-induced amnesia. [10, 11, 12]

Neuroprotection and Development of New Brain Cells

It protects and maintains overall brain health by promoting the development of new brain cells and enhancing the body’s capability to repair damaged cell membranes. This attribute is a significant longevity advantage. [13]

Increases Energy and Speeds up Recovery

Because it stimulates the production of human growth hormone (HGH), Alpha-GPC is valuable for individuals looking to perform better, increase lean muscle mass, feel peak energy during workouts and recover quickly afterward. A pilot study shows that 600 mg of Alpha-GPC taken 90 minutes before bench pressing increases power output by 14%. [14, 15, 16]

Increases Attention and Enhances Mood

Users report that using Alpha-GPC provides distinguished mental clarity while improving mood. This elevating effect is explained partially by the additional choline it presents, which increases attentiveness and promotes effortless clear-thinking. It’s also a link to its production of human growth hormone, which provides energizing, longevity effects. [17]

In combination with other nootropics, it offers adequate choline to achieve optimal cognitive enhancement effects, and it prevents the minor headaches often associating with racetams.


Mechanism of Action

How Does Alpha-GPC Work?

Alpha GPC benefits
Alpha-GPC structure

Alpha-GPC is comprising of choline, glycerol, and phosphate and its classification is cholinergic. The mechanism of its action is examined with high understanding. However, the manner in which it affects some neuronal functions remains unclear. A water-soluble supplement that is fast-acting and highly bioavailable orally. It crosses the blood-brain barrier shortly after ingestion, and effects work within an hour. It metabolizes into a combination of choline and byproduct glycerophosphate. Additional choline forming by Alpha-GPC is the essence of its nootropic abilities.

On Acetylcholine

It is a fundamental associate of many cognitive functions including memory formation, learning capacity, and attention. By stimulating the production of acetylcholine, it acts as a neuroprotectant; maintaining neuronal health and preventing potential damage. [Ref 1, 2, 3, 4]

On Dopamine

Oral ingestion of Alpha-GPC can also be dopaminergic, by increasing dopamine release during neuronal action potentials and possibly by stimulating the expression of receptors. It also has involvement in increasing brain serotonin concentrations following oral administration. [22, 23, 24]


Dosage

What is The Recommended Alpha-GPC Dosage?

Alpha-GPC digests and absorbs smoothly and is gentle on the stomach taken at the typical dose of 300mg. Although many nootropists tend to prefer a dose of 600mg, with a total daily intake ranging from 300 to 1200 mg, either at once or split into two doses. [25]

Personally I find 300mg is effective enough especially because I almost always take it as part of a stack. If not Aniracetam then its Piracetam, Phenylpiracetam or Noopept. On the few occasions where I took it on its own, I still felt very at ease and eager to produce, learn, move.

As with any other nootropic, start with the lowest effective dose and build up gradually as desired.


Side Effects

What Are Alpha-GPC Side Effects?

Some side effects rarely occur, such as headaches, fatigue, nervousness, nausea, diarrhea and gastrointestinal distress. It may rarely induce dizziness and low blood pressure in some individuals.

Personally never experienced any side effects from its use. But I’ve never taken more than 300mg in one dose, and never more than 600mg in a 24-hours frame.

Note: Alpha-GPC interacts adversely with scopolamine. Those using scopolamine are advised to avoid it.


User Experiences

Here is 3 random alpha-gpc reddit community thoughts and experiences:

First reddit user experience:

This might be considered a bit on the excessive side, but I’ve been taking 300mg of GPC daily for ~2.5 years. I’ve found it to be one of the most effective ways to treat the severe anxiety that I’ve suffered throughout most of my life. Initially, I periodically experienced the insomnia you mentioned, but that passed within a month or so. Every once in a while, I’ll go several days without taking the stuff. During those short, sporadic periods of “cycling off”, I’ve noticed that I feel significantly more “dull” and lethargic than I otherwise do, but that might just be placebo in action. I understand that such a lengthy use of an under-researched substance might be a bit careless. I suppose the greatest concern would likely be down regulation of choline receptors and reduced choline production, but I doubt that any studies of the effects of long-term heavy choline supplementation currently exist to prove that one way or another. [find thread here]

Second user experience:

As the title says, Alpha GPC has next to eradicated my social anxiety. It’s incredible. Only downside is I’m having a hard time sleeping at night. Guess my question is, how long can I cycle this stuff safely. [find thread here]

Third user experience:

So I used to take Alpha GPC, as well as a ton of other nootropics for a few months but recently took a couple months off. Anyway, I’ve been trying to get back into them so I took only Alpha GPC this morning. I already feel more at ease with everything. I font have much depression but its crazy how great I feel already. I happened to just see this and put it all together. [find thread here]


Conclusion

Alpha-GPC is a compound with decades of research, and its worldwide appreciation comes from the effects of memory enhancement. In addition to the dominant nootropic qualities, it’s also an excellent companion to racetams. Moreover, it stimulates the production of human growth hormone. This hormone production improves strength, reduces recovery time, and support the development of lean muscle mass. Therefore; it is an excellent nootropic for individuals who enjoy leading an active lifestyle.


Frequently Asked Questions

Is Alpha-GPC Safe?

Personally never experienced any side effects from its use. But I’ve never taken more than 300mg in one dose, and never more than 600mg in a 24-hours frame. Additionally, according to a study by Food Chem Toxicol in 2011 said Alpha-GPC does not appear to possess mutagenic activity, as well that No Observed Adverse Effect Level (NOAEL) for humans was at least 150 mg/kg over 26 weeks based on extrapolation from dogs.

Is Alpha-GPC the Same as Choline?

Alpha-GPC is cholinergic (compounds that increase the levels of acetylcholine or choline in the brain). While Choline is actually a molecule mostly used for turning into acetylcholine, the learning neurotransmitter, as well as live health agent reducing fatty liver buildup.

Is Alpha-GPC Water Soluble?

Alpha-GPC is very water-soluble. It’s much more likely to be soluble in water than non-polar solvents such as fat. The reasons why I would say that are as follows: the molecule itself has two ionic sites, ionic organic compounds generally have at least some solubility in water. Two ionic sites significantly increases the likelihood of it being soluble in water. Furthermore, the molecule has many OH a Oxygen moieties. Molecules with a lot of oxygen containing moieties are also likely to be water soluble, due to the hydrogen bonding of water. A good example of this are monosaccharides, they are not ionic, yet dissolve readily in water because of the numerous oxygen containing functional groups on the molecule.

Does Alpha-GPC Work?

Yes. Alpha-GPC is comprising of choline, glycerol, and phosphate and its classification is cholinergic. The mechanism of its action is examined with high understanding. However, the manner in which it affects some neuronal functions remains unclear. A water-soluble supplement that is fast-acting and highly bioavailable orally. It crosses the blood-brain barrier shortly after ingestion, and effects work within an hour. It metabolizes into a combination of choline and byproduct glycerophosphate. Additional choline forming by Alpha-GPC is the essence of its nootropic abilities.

Does Alpha-GPC Keep You Awake?

Although traditionally known as being non-stimulating, some persons do report cognitive stimulation with supplemental alpha-GPC.

Can Alpha-GPC Increase Dopamine?

Yes, some research studies suggests that oral ingestion of Alpha-GPC can be dopaminergic, by both increasing dopamine release during neuronal action potentials and possibly by stimulating the expression of receptors

How Much Alpha-GPC To Take?

A standard dosage of alpha-GPC is 300-600 mg, according to the most common label doses. 300mg for general use, and 600 mg for increasing power output. This dose is in accordance with the study using alpha-GPC to enhance power output (600 mg) and the two studies noting an increase in growth hormone secretion, and is likely a good dose to take for athletes.

and Alpha-GPC: 300 mg.

How Much Alpha-GPC to take with Aniracetam?

Same as with Piracetam, when taking an Aniracetam and Alpha-GPC stack, the ideal dosage would be: 750 mg of Aniracetam and 300 mg of Alpha-GPC.

How Much Alpha-GPC to Take with Noopept?

Ideally when pairing Alpha-GPC and Noopept stack, the dosage would be 30mg of Noopept (or 15mg if you prefer 2 doses per day instead than one), and 300mg of Alpha-GPC.

When to Take Alpha-GPC?

Alpha-GPC can be taken any time, although preferably not late in the evening due to some reports that it stimulates some people. Other than that, you can take it any time with or without food because its water-soluble.

Where to Buy Alpha-GPC?

Alpha-GPC can be bought on many places. You local drugstore, pharmacies, department store where they have supplements. Its also available with many different vendors online and on Amazon.

Which is the Best Alpha-GPC brand?

Personally, I only used Nootropic Depot’s Alpha-GPC which I highly recommend. It can be found either on their website or on Amazon here.

Does Alpha-GPC Increase HGH?

Yes, Alpha-GPC increases growth hormone, but due to a rapid normalization of growth hormone concentrations within 2 hours it may not lead to practical benefits.

Is Alpha-GPC Natural?

Yes, Alpha-GPC is a natural compound.

Introduction

What is Phenibut?

Phenibut might not have as widespread use as other nootropics on the market. However, it has demonstrated numerous benefits over tens of decades through both formal studies and anecdotal documentation. It’s a nootropic designed to simulate the inhibitory neurotransmitter γ-aminobutyric acid (GABA) that acts on the central nervous system. It marketed as a psychotropic with a positive effect on mental capability and improved neurological functioning. The anxiety diminishing effects of phenibut are the most praised of all its attributes. Once anxiety is resolved, natural sleep patterns and enhanced cognitive processes shortly start following.

Phenibut Skeletal Structure

Phenibut was invented in the Soviet Union almost half a century ago. A fascinating, documented anecdote reveals that Russian cosmonauts were supplementing with phenibut especially during the 1975 mission Apollo-Soyuz at the joint of the USSR and US. It remains in use to date in Russia as a treatment and remedy to many conditions including anxiety, depression, prevention of motion sickness, even alcohol withdrawal syndrome, to name a few. Not to mention, of course, its nootropic attributes.

Phenibut, sold under the brand names Anvifen, Fenibut, and Noofen among others, is a central nervous system depressant with anxiolytic and stimulant effects which is used in the treatment of anxiety, insomnia, and for a variety of other indications.

Phenibut Reduces Anxiety and Stress Levels

Anyone who suffers from anxiety knows that it can be extremely hard to control, it’s not just something that can simply be ‘switched’ off. When taking Phenibut, you will be able to gain more control. Once administered, you can expect to feel more relaxed and composed.

This attribute is the most appreciated benefit of phenibut which is documented by Izyaslav Lapin (R). Anxiety is often the result of overactivity in brain’s concentration and overthinking and analyzation of unnecessary, or irrelevant matters; often with the inability to realize the direction to which the train of thought is heading. Turning down and resting the continuous and distracting neuron processing frees the negative thought preoccupation which in turn opens a fresher, vibrant, and often productive range of possibilities.

Phenibut Increases Sociability

The anxiolytic effect leads to openness towards social interaction which by itself is an issue almost always associating with anxiety disorders. Studies suggest phenibut to be a promoter of enhanced cognitive processing, but the fundamental reason practically still due to the anxiety relief. Those seeking to improve interaction in social settings report better results with the supplement in comparison with alcohol or prescription medication such as benzodiazepines. While attempted anxiety-reduction using traditional tranquilizers often lead to drowsiness and reduction in motor skill and cognitive ability, phenibut seems to mitigate the feelings, except without the associating and undesired side effects that associate with traditional prescription medication. [R]

Promotes Healthy Sleep Patterns and Quality

People living through the depression, anxiety, stressful life events, while going through hormonal changes such as menopause, often report degenerating sleep quality, sleep disturbance, and insomnia. While melatonin is a remarkable and beneficial supplement to consider, some require pharmaceutical sleep aid for more sedating and sleep-inducing effects. Lack of continuous quality sleep can cause an impairment in cognitive processing, opening the way to more anxiety and more sleep disturbance. Used consciously, Phenibut an excellent supplement that can restore significant, natural sleep patterns, duration, and quality. The ability to fall asleep, remain asleep, maintaining an extended period of healthy, rejuvenating deep sleep is attainable with phenibut. [R] [R]

Phenibut May Improve ADHD

Since phenibut improves attention, it may also help with ADHD symptoms. In one clinical trial of 50 children with ADHD, it improved cognition, self-control, sustained, attention, and memory after 1 month (500-700 mg/day). One month is a short time for evaluating ADHD effects; long-term studies need to determine if the beneficial effect can be sustained.

Selfhacked

My Thought on That

Well I am ADHD and have taken Phenibut and similar “GABA-acting” drugs, such as gabapentin for about a year. Its interesting that, at the time, I had not been diagnosed with ADHD yet and was not aware nor had a clue what ADHD is. I self-medicated with gabapentin and phenibut along the way, and now years later, looking back at how routinely I was taking it, I realize the reason I was hooked and amazed by it was its effect on me as an ADHD, prior to any anxiety triggers that might associate. It was a transformative medication – but overtime, mister W (withdrawals) had been sitting and just waiting for me to get off it in order to introduce himself – and that horrible experience was almost equally as transformative.

Mechanism of Action

How Does Phenibut Work?

Gamma-aminobutyric acid (also known as GABA) is the chief inhibitory neurotransmitter in our central nervous system.The blood-brain barrier makes supplementing with GABA close to being ineffective due to its inability to bypass the blood-brain barrier. However, phenibut crosses the barrier due to the addition of the phenyl group molecule. Once in the brain, it slows the neuronal excitability, resulting in the effects as mentioned earlier.

GABA frees up channels in the neurons, reduces the function of other neurotransmitters, and diminish collective fears and anxieties in the neuron. It remains vague whether or not phenibut binds to the GABA receptor, although some studies suggest that it only does so in high concentrations.

Lapin’s research found that phenibut increases the levels of dopamine as well. Dopamine is another vital neurotransmitter in the central nervous system. It regulates emotions and creates the reaction of what we call motivation.

More from the Web

In order to affect one’s cognitive functioning, mood, and overall relaxation levels, this supplement needs to cross the blood-brain barrier. GABA cannot effectively do this, while Phenibut can. This is due to a phenyl group that is attached to GABA’s structure.

Naturally, GABA balances out the effects of chemicals that stimulate neurons. When neurons are overstimulated, this can lead to feelings of anxiety and restlessness. Since Phenibut works like GABA, it helps to restore this balance.

The result is neurons firing only when they’re supposed to. Once Phenibut reaches the brain, it targets GABA receptor sites.

It is believed that Phenibut is non-selective, as it stimulates both GABA-A and GABA-B receptors. This allows you to feel a sense of relaxation, lessening anxiety. This is fairly different than other nootropic supplements, which is why it’s beneficial in a stack.

Phenibut also stimulates dopamine receptors, which is key in terms of your mood. Once dopamine is increased, you will experience a more positive mood. Users also tend to experience high levels of motivation, allowing them to achieve more.

Dosage

How to Take Phenibut?

Phenibut is a potent compound. Start at the lowest effective dose and monitor your response to it, then adjust according to your needs. A dose of 250 mg is a good starting point for first-timers with no tolerance. 500 mg would be ideal in my opinion.

Phenibut effects build up gradually, so avoid taking a second dose without a reasonable timeframe in between. Initial kick-in is around 45 minutes after consumption, and optimal peak effect is usually 2 hours later.

Phenibut is GABA (the major calming neurotransmitter in your brain) with a phenyl ring attached, which allows the molecule to pass your blood-brain barrier and reach receptors in your brain. Phenibut was originally developed for Russian astronauts, to ease the stress of flight and help them sleep in space. It relieves anxiety and drives you into deeper sleep. Phenibut is also a nootropic: it boosts cognition, giving you relaxed clarity of thought.

Phenibut can be addictive, so it’s very important to take it correctly. The two common mistakes people make are taking phenibut daily and increasing the dose over time. Phenibut’s effects last for 48-72 hours, so you only want to take it once every three days (twice a week max).

You also want to cycle it to avoid tolerance. Go two weeks on phenibut, two weeks off. Don’t go past 250 mg doses; if you stop feeling the effects at 250mg, cycle off for a couple weeks. Don’t mix phenibut with alcohol, either. It amplifies the effects, which can be dangerous.

Dose: 250 mg (never higher)

Time: Anytime, but only twice a week max (Monday and Thursday, for example).

Do two weeks on phenibut, two weeks off.

Side Effects

What Are Phenibut Side Effects?

Like anything we put inside our body, the best source of measurement and criticism is the human body itself. To avoid adverse effects, start at a low dose and see your body’s reaction and adaptation to it.

Often individuals report dizziness and drunk-life sensation as a side effect. On the other hand, many people use to supplement with phenibut for the very same impact.

The experience is entirely subjective. Rarely users report fatigue, nausea, and stomach discomfort. People on epilepsy medication or MAO inhibitors are advised to consult a professional doctor before taking phenibut. Alcohol should be consumption should cautiously within reasonable limits ion due to the synergistic effects of alcohol and phenibut.

Avoid taking on a daily basis.

Phenibut has high abuse potential. If taken regularly, be mindful of possible withdrawal effects upon discontinuation. It’s wise to limit intake to once or twice a week. Thereby maintain a low tolerance, enjoy its benefits, and avoid building a destructive habit of use. Do not underestimate the power of phenibut and do your research if you decide to include it in your stack.

Legal Status

Is Phenibut Legal?

  • As of 2018, Phenibut is not a controlled substance in any country apart from Australia and Hungary.
  • In 2015, it was suggested that the legal status of phenibut in Europe should be reconsidered due to its recreational potential.
  • In February 2018, the Australian Therapeutic Goods Administration declared it a prohibited (schedule 9) substance, citing health concerns due to withdrawal and overdose.[R]
  • As of 14 November 2018, Hungary added phenibut and 10 other items to its New Psychoactive Substances ban list.

User Experience

This is one of the most interesting user experiences I’ve read on Phenibut. It was posted by Reddit user on Phenibut sub-Reddit:

We all love phenibut. It removes our social anxiety (which everybody has nowadays), removes inhibitions we have as humans, removes a mental condition we didn’t know we had before the use of this substance, makes us more motivated so we can focus on tasks.

Phenibut is a substance which is very handy to treat all of this. You can use it for the rest of your life. You will have continuous anxiolysis, but the motivational aspects will disappear. This is because of a down-regulation of GABA-B on the lesser hand and especially down-regulation of your dopamine receptors. It’s called tolerance.

I was 3 years addicted and I have a long road of nootropic use behind me. Herbal extracts, synthetic nootropics, soft- and hard drugs… Some to get high, others to make me smarter and others to remove phenibut tolerance. But 99% of these maybe 100+ compounds I used really helped.

However I discovered 2 very useful substances on my long road.

First of all, memantine. It’s an Alzheimer’s medication. It works as an NMDA-antagonist. NMDA receptors are receptors in your brain part of the glutamate system, used for learning and memory. These are said to reverse tolerance for stimulants such as caffeine and amphetamine. Phenibut can be classified as a relaxant and stimulant, and while it has like all the other stimulants tolerance problems, NMDA antagonists come in handy to reduce this. Various reports of people you can find on the internet indeed back this claim up. Other compounds who work in this system are ketamine, DXM (cough surpressant), MXE and N20. We also call these compounds dissociatives. Memantine is dissociative in higher doses as a recreational drug but for Phenibut it’s more suited in 1-10mg doses for tolerance reduction. It’s also a dopamine agonist. You read that good: an NMDA-antagonist (reduces tolerance for dopaminergic stimulants) and dopamine antagonist. So memantine is a stimulant while reducing tolerance for stimulants. In my use of this substance I learned this: start low – with 1 mg to begin with. Because memantine is also a nicotinic acetylcholine receptor, it can have anti-nootropic effects the first week while starting. This may contribute to initial worsening of cognitive function during early memantine treatment and is the reason why many people don’t take memantine for longer than I week and why you can’t find many succesful reports on the internet. I was very succesful in doing this but had to way for minimum 2 weeks. Memantine is also the best in the 2 chemicals I describe in the post when comparing price/efficacy. You can find 10 grams for €75 on the internet (contact me when interested).

The other succesful substance I used is fasoracetam. It’s a nootropic in the racetam family. Some other nootropics in this family are piracetam and aniracetam. 2 famous nootropics known for there ability to increase blood flow in your brain and make you more sharper. But only fasoracetam has the ability to increase GABA-B receptors in the brain. It’s no GABA-B agonist and no GABA-B antagonist. This is good to know because GABA-B antagonists have a negative on your ability to relax in the beginning and are dangerous in general (because they can damage your nervous system). GABA-B antagonists don’t know as far as I know, so this is purely hypothetical. Just wanted to say fasoracetam is an ideal substance. Fasoracetam is more expensive compared to memantine, I can find 10 grams on the internet for €60. Since you need to use higher doses (10-50mg) it will cost you more.

Because of my discovery of these substances and success with it, I decided to be a social butterfly and highly motivational person for the rest of my life. I decided it long before I discovered this, but I couldn’t make it true because of the disappearment of phenibut’s effects. I hope I stay them for the rest of my life.

My current method? I make 000 capsules which hold approximately 800mg powder. With a weighing scale I weigh 100g phenibut, 2.5g fasoracetam and 0.5g memantine. Then I mix it. By doing this I get a nice mixture of these powders. Be aware, people will say this is not 100% mixed because you do it manually. But this is not a huge problem, it’s not really a bad thing if you get sometimes 1 mg memantine and other times 3 mg memantine. If you want to do it more precisely, you can buy a super accurate weighing scale and put 1mg memantine every morning under your tongue. But you lose the comfort of easy dosing.

Thanks for reading 🙂

Conclusion

Phenibut is a useful anxiety-relieving supplement that does not cause the infamous drowsiness often accompanying anxiety medication. It is well-studied and standing amongst the top in line when it comes to anxiety relief, sleep regulation, and cognitive improvement.

How long for Phenibut to kick in?

Phenibut has a long onset time of around 1.5 – 2 hours until its peak effect, for most people. The time that it takes to kick in depends on the amount of food in your stomach, your metabolism, the dosage, and how you took it. Taking Phenibut sublingually results in a faster onset time that taking it with water or juice.

How much Phenibut to take?

For first-time, 250mg, If you’re experienced and know well enough about it, you can take 500mg. The best approach is to start low and see how you react to it, and increase accordingly if needed. But keep in mind that it takes around an hour and a half to be felt, so make sure you keep about 2 hours interval between doses.

Introduction

What is Piracetam?

Piracetam is a nootropic that enhances memory and brain function. It’s been around for a surprisingly long period, thus becoming a “classic” amongst the rest on the list. It allows creative and logical thoughts to run together into a stream of higher-level reasoning. It is the father of all nootropics and often the first choice for individuals looking to improve cognitive abilities.

Nootropics such as Phenylpiracetam, Fasoracetam, and Pramiracetam are all derivatives of this compound.

“Synthetic molecule designed to enhance brain function. Piracetam is the basic ‘racetam’ molecule of a family of related compounds”

Examine

Furthermore, it increases the amount of knowledge the brain can process, as well as preserve, for future reference. Piracetam is an invention by Romanian psychologist and chemist Dr. Corneliu E. Giurgea dating over 50 years ago, to create a supplement to enhance memory and learning capacity. It is in medical use in Europe, Russia, and South America, amongst other countries, as a treatment for a type of muscle spasm called molycous. However, due to its nootropic effects, it became one of the most prominent cognitive enhancers. Confined studies show that Piracetam reverses the effects of Alzheimer’s disease as well as dementia in elderly individuals. There is also sufficient evidence proposing that it prevents brain damage caused by excessive alcohol intake.

“Piracetam is a medication in the racetams group, with chemical name 2-oxo-1-pyrrolidine acetamide. It is approved in the United Kingdom but is not approved in the United States. In the UK, piracetam is prescribed mainly for myoclonus, but is used off-label for other conditions.”

Supporting Research

Piracetam Improves Memory

Piracetam is popular first and foremost because of its positive, profound impact on improving memory. In a meta-analysis of 19 different double-blind studies, Piracetam shows an exceptional improvement relating to memory. However, it is important noting that memory improvement effects build up gradually. The studies show minor improvement after a 7-day administration and a significant increase after a 14-day administration. Today, most individuals benefiting from Piracetam do so entirely for its memory-enhancing result. [1] [2]

Piracetam Enhances Cognitive Function

There is a healthy amount of studies administering the effects of piracetam on cognition enhancement. Piracetam improves cognitive performance especially in individuals with neurodegenerative conditions. While most studies are governing elderly individuals with chronic disease, there is nevertheless sufficient evidence proving it to be beneficial for healthy, young adults. Piracetam is especially helpful for individuals suffering from chronic conditions. Healthy individuals tend to embrace it for the nootropic traits. [3] [4] [5]

Neuroprotective and Prevents Neurodegeneration

Piracetam supports neuroprotection as well as encouraging healthy brain growth and protects as well as prevents it from neurodegeneration related to aging. In this particular area, it serves greater as a preventative rather than a treatment. Prevention is of often the best medicine there is. [6] [7]

Increases Self-Awareness and Promotes Clarity of Thought

There is evidence indicating that piracetam improves sensory perception by increasing acetylcholine activity in the hippocampus. In this particular example, it suggests an increase in self-awareness, zen-like state as well as an increased feeling of overall well-being. Many report colors are appearing brighter and more vivid. Furthermore, many report a heightened sense of perception and a higher level of vibration, along with a feeling of connectedness to nature and other beings. [8]

Reduces Anxiety, Stress, and Eases Depression

In a study by the Department of Pharmacology in India examining the antianxiety effects of Piracetam taken orally over the period of 7 and 14 days, it confirms that; although a single dose does not seem to induce immediate anxiolytic effect, a delayed anti anxiety impact was rather apparent. It is especially evident in individuals with anxiety due to alcohol withdrawal. Anecdotal reports imply piracetam is a useful tool for managing stress and anxiety levels, and to a certain extent, easing depression symptoms. However, clinical research is limited relating to depression. Therefore, piracetam should not be a source to rely on should you be clinically diagnosed with depression. Use with caution. With that said, it is nevertheless useful and worth experimenting if your anxiety is somewhat generalized or social [9] [10] – (high-five btw, makes two of us!)

Improves Verbal Learning and Fluency in Dyslexics

Over a 21 day study, piracetam shows an increase in verbal learning by 8.6% compared to placebo in healthy volunteering individuals. In patients with dyslexia, however, verbal learning shows a significant 15% increase. Piracetam, therefore, proves to be beneficial to individuals with dyslexia. Moreover, children tests in letter analyzing while receiving 3.3mg per day over 36 weeks showed an increase in letter-matching as well as reaction time. [11] [12]

Piracetam Helps with Schizophrenia

Piracetam shows to reduce symptoms of uncontrolled movement in individuals with schizophrenia. Furthermore, Piracetam may have a protective effect upon glutamatergic receptors within the hippocampus. [13] [14]

Mechanism of Action

How Does Piracetam Work?

Interestingly, piracetam doesn’t seem to show any effect on the GABAergic system even though it is a cyclic derivative of GABA. Piracetam’ mechanism of action relates to how it increases the activity of acetylcholine, a neurotransmitter involved in memory function. It works to improve memory by making the transfer of acetylcholine more effective. It also affects NMDA glutamate receptors which also play a role in the memory formation and learning processes. Scientists believe piracetam works through these possible mechanisms in the brain: compromised neuronal cells experience a loss of fluidity which prevents signaling molecules from crossing the lipid bilayer membrane of the corpus callosum, the part of the brain separating the left and the right hemispheres. Piracetam can restore or even increase the membrane fluidity of these neuronal cells, making neurotransmission a more effective and effortless process.

“Overall, Piracetam increases glucose and oxygen consumption in brains which precedes cognitive improvement (as these benefits are global (not favoring certain brain regions) and more significant in cognitively impaired persons, both of which are in accordance with interventions in humans).

The exact mechanisms underlying the enhancement of glucose and oxygen consumption are currently not established.

Piracetam shows affinity for two subsets of AMPA (glutamate) receptors, Glu2 and Glu3, and may attenuate the rate of action potentials. It does not appear to directly act upon the other two glutamate receptors (Kainate and NMDA) although the ability of piracetam to possibly increase receptors in general in aged mice may influence these two receptor classes.” – Examine

Protein synthesis is an essential part of memory-storage in the brain. Piracetam can cause an increase in learning and memory when various steroids transport them in the brain. When steroids in the brain are blocked, the effects of nootropics are blocked as well. Recruitment of AMPA receptors that are generally not part of synaptic transmissions, essentially making more receptors available, when would undoubtedly cause an increase in learning. Moreover, of course, acetylcholine increases and increased transmission of this critical neurotransmitter which is one of the most important in memory storage and learning processes.

Dosage

How To Take Piracetam?

The typical Piracetam dosage for adults is between 1,200 to 4,800 mg a day.The most effective dose is 1,600 mg, taken three times a day, making a total of 4,800 mg per day.

For optimal results pair it with 300mg of Alpha GPC, CDP-choline, or your choline source of choice.

Side Effects

What Are Piracetam Side Effects?

Piracetam is considered very safe and side effects rarely occur. [15]

Headaches are often reported. It is due to lowered acetylcholine levels in the brain due to racetams utilizing them. Therefore, it is very important to pair racetams with a choline source like Citicoline or Alpha-Gpc, especially if you notice a headache after supplementing with Piracetam, or if you do so on regular basis.

Not only will choline prevent or eliminate the headache, it will even work synergistically together with Piracetam (or any other racetam) and potentiate both of their cognition benefits. [16]

User Experiences

A user on reddit shared his following piracetam experience which helped him getting off hard drugs:

So a bit of background. I have ADHD and aspergers and piracetam has been a godsend. Honestly i’ve never felt better. When I was diagnosed with ADHD and aspergers my life basically turned crappy and I started experimenting with drugs to “alleviate” my conditions. I’ve lost friends, lied, cheated and made a fool of myself. Now with piracetam i’ts another story. I always had a fascination with psychotropic substances, and went and abused ritalin for a long while. This lead me to have even worse depression and anxiety. With piracetam thought, it made me stable and understand that my drug abuse was not amusing, specially for those around me. Now I focus on what is important and I don’t care to get high, drunk or abuse anything. I’ve started dedicating more time to my hobbies and passions. I’ve also noted i’m more honest and don’t feel the need to judge others to make me feel better or have to justify myself. I take it when I need and take breaks. Also noted less apathy and dissociative/ antisocial behaviour. I was actually nice to my neighbours for once(Bc honestly i’ve been an asshole my whole life) Even so I’m still waiting to see if this change is permanent(I hope it is) If you have ADHD or some ASD I recommend this! But… Research your stuff and stay responsible. Meds are not the solution, they’re only one of many tools in your arsenal to improve yourself. Exercise, healthy diet are essential to getting better as well. ]Sorry if I seem overly exited, I just wanted to share my story to a community that showed me that I don’t have to take possibly addictive substances to be a better person. Nootropics worked for me. – an experience and condition very similar to my own.

Another reddit user experience, in which he says:

So I was using Piracetam sporadically for past 2-3 weeks, at the beginning I thought it is just a hyped up nootropic or maybe not potent at 800mg-1200mg dose or ineffective in comparison to other racetams (I have never tried any other racetam.) But today I can feel the effects, I took CDP choline for the first time this morning with 1 Piracetam 800 mg tab in the morning and and 1 at night sometime earlier. I am able to think quick, able to respond to what my friends say quickly and the music sounds so so good especially the percussions and I am only wanting to listen to fast paced songs, I did not expect a stimulating effect from piracetam, even I am typing this at a great pace, believe me I did not take caffeine. No benefit in terms of focus, I also didn’t expect it, in fact I feel a little distracted.

Conclusion

Overall, Piracetam (alongside Noopept, if I may add) is one of the most fundamental brain boosting nootropics out there. It has very noticeable effects on increasing memory and learning capability, and certainly has the potential to enhance cerebral performance.

Student looking to get the edge on academics, or merely wanting to think smarter and faster in their day to day life, this is a great nootropic to start with to introduce you to the world of nootropics. As well as safer than many other alternatives – especially stimulants, that most college students seem to favor.

Frequently Asked Questions

Is Piracetam Legal in the US?

It’s legal to buy, but might not be legal to sell. FDA regulations affecting “dietary supplements” may not apply to piracetam. But regardless, those regulations only control the sale of substances and not the purchase of substances. So buying is OK.

What’s the difference between Piracetam and Noopept?

Noopept seems to be effective – and longer lasting than Piracetam, due to its effect on the NMDA receptors. It works in a similar way and has similar mechanisms as Piracetam, but at a much lower dosage – when it comes to whole brain function. The research available along with the anecdotal reports seem to strongly support this claim. “Oral ingestion of Noopept results in a very rapid absorption and metabolism of Noopept, although the kinetics of metabolites (which are thought to be bioactive) is not yet known. A true bioavailability study has not been conducted, although it appears that an oral dose is about the equivalent of one tenth an injected dose (10% bioavailability).”

Whereas Piracetam shows affinity for two subsets of AMPA (glutamate) receptors, Glu2 and Glu3, and may attenuate the rate of action potentials. It does not appear to directly act upon the other two glutamate receptors (Kainate and NMDA) although the ability of piracetam to possibly increase receptors in general in aged mice may influence these two receptor classes.”

What are the long-term possible risks of using piracetam?

Although there is no hard evidence on the matter, some users would say Piracetam as well as many other cholinergic nootropics (with notable exceptions like coluracetam), can subdue mood. It can make you have trouble turning off automatic memory associations, and being ‘locked’ in a particular state of consciousness for many hours.

What is the correct way to take Piracetam?

“The correct way to take piracetam is whatever way works for you. If you cannot abide the bitter taste, taking piracetam in pills or capsules is the better way to go. I found that the bitter taste grew on me, so paying extra for capsules (or pharmaceutical tablets with excipients and dyes) is not worth it. For some, it’s taking it constantly, like 600–1000 mg three times a day. For me, I often take the entire daily dose in the morning, which greatly helps my circadian rhythm sync to the day when it is drifting into my old pattern of night-owl-ism. I know people who only take piracetam in certain circumstances, like before a public talk or interview, or flying on an airplane, or traveling to a high-altitude location for business or vacation. I take it when I’m going to be putting demands on my verbal, editing and writing skills. For people with high cholinergic tone (like me), taking piracetam with minimal cholinergic support is best. For a more cholinergically recessive person, taking piracetam with B5, choline, phosphatidylcholine, etc. is best. So I think there is no one correct answer to your question.”

Why does piracetam take so long to act?

Piracetam does not efficiently cross the blood-brain barrier, so it takes a while to build up enough to modify neurological activity. The time depends on the dose, which is why it is common practice to use a loading dose for the first day or three. When I used an aggressive 6400 mg loading dose (2.6 times the standard daily dose), I got conspicuous effects the first day. The “conservative” escalating loading dose that I suggest is wise for children with Down’s syndrome takes roughly a week to get the level of piracetam into the therapeutic range. The delay with piracetam also depends on the integrity of your blood-brain barrier, which if low facilitates piracetam acting quickly.

Why is piracetam considered a nootropic?

The research done on piracetam actually led to the coining of the term “Nootropic” and is the first member of the “Racetam” class of cognitive enhancers. There are several definitions of Nootropic. Corneliu E. Giurgea, the lead scientist that termed Nootropics, has his own list of qualifiers. More anecdotally, Nootropics must meet two identifying criteria:

1. Enhance some form of cognition.
2. Have either neuroprotective or regenerative effects, or at the very least possess very few side effects and extremely low toxicity.

For the first Qualifier:

Chemically, piracetam is a synthetic derivative of our major inhibitory neurotransmitter, GABA, Piracetam is understood to act primarily on the glutamate system within brain areas specific to memory and learning.

Research suggests that, as a primary mode of action, Piracetam increases neural activity in the hippocampus and cortex by upregulating AMPA and NMDA receptor densities, thereby enhancing glutamate transmission. Piracetam has also been reported to increase cerebral blood flow and the acetylcholine efficacy in the brain, both of which have been suggested to positively influence focus, memory, and learning.

Second Qualifier:

Piracetam is one of the most research nootropics, probably the most researched synthetic one. Piracetam demonstrates relatively low toxicity and shows promise in studies that examine its potential in cognitive decline. [R]
