Summary: Agmatine is an amino acid that offers a wide of cognitive boosting benefits. It also has excellent effects on reducing neuropathic pain, as well as drug addiction habits. It is neuroprotectant and can reduce tolerance built to many medications like benzodiazepines, morphine, and other painkillers. It also synergizes with SSRI’s & cannabis.
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.
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.
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:
For treatment of neuropathic pain: 1,000 to 2,500 mg of agmatine (daily)
For improving cognitive function: 200 to 500 mg of agmatine (daily)
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
“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.”
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]
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

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.
The typical dose for general wellness and gut health is 500mg per day taken in the morning on an empty stomach 800to2,400mg are the most common across clinical studies. However, for a chronic health condition, consider a higher dose. Studies concerning addiction and mental health issues use doses closer to 3000 mg/day.
Daily doses should be taken at 2-3 times a day.
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?

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.
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  to enhancing brain function. 
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.
Research proves ALCAR beneficial to the brain and body in many ways. From enhancing cognitive abilities  to increasing energy , reducing pain, and even preventing damage from alcohol consumption. 
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. 
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. 
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. 
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.  
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.  
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.
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.
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).”
What Are Acetyl-L-Carnitine Side Effects?
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.
Nausea is the most common side effect. It is easily preventable by taking ALCAR alongside food rather than on an empty stomach.
Headaches are the second most common side effect, which may imply an excessive amounts of choline.
Users report that headaches from ALCAR use decrease when they reduce the amount of choline in their stacks and diets.
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
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: L-theanine is a natural amino acid, often called the “natural xanax”. It almost only exists in green tea leaves. It works brilliantly in unwinding and relaxing the body and brain without causing drowsiness, while reducing stress and increasing cognitive function. Due to not causing drowsiness, it is the perfect choice to combine with stimulants of any sort to take the edge off.
It is an amino acid that naturally exists in green tea leaves as its main active ingredient, and that is the only source that provides it. It is famous for its fantastic nootropic features such as improving memory, expanding learning capacity, as well as providing a calming, zen-like effect.
L-Theanine, for the most part, is a relaxing but not sedating amino acid that is synergistic with stimulants such as caffeine as it can ‘take the edge off’. It is effective by itself in the standard supplemental dosages as well, and although it can be attained via a diet high in green tea ingestion that is the only dietary source of L-Theanine.
A review by researchers of a small set of trials concluded that there are benefits of L-theanine in reducing acute stress and anxiety in people with stressful conditions. [R]
Oral intake of L-theanine in rats at feasible dosages reduces circulating biomarkers of stress with or without an actual stressor being present. Therefore, it reduces the adverse effects of stress such as memory impairment. Reductions of perceived stress reported in human subjects given oral theanine at the standard dosages. [R] [R] [R]
L-Theanine Improves Memory, Attention, and Cognition
In a 16-week long study on individuals with mild cognitive impairment, supplementing with l-theanine shows an improved delayed recognition as well as immediate recall comparing to those receiving a placebo during a mental exercise. Furthermore, attention span and alertness levels increased during the memory test. [R]
L-Theanine Enhances Sleep Quality
Theanine enhances sleep quality. In a study measuring sleep time with individuals supplementing with L-theanine, sleep time increases by 11 and up to 21%, therefore making it a valuable compound for achieving better nighttime sleep. (R)
L-Theanine Promotes Longevity and Increases Lifespan
In a study using the model organism C. elegans, L-theanine shows to promote longevity and promote healthy and increased lifespan. Due to those findings, the study suggests that the compound might have similar effects on mammals and humans (R)
L-Theanine Reduces Symptoms of Depression
L-Theanine intake for a period of eight weeks during an open-label study helped easing depressive symptoms, anxiety, sleep disturbance, as well as cognitive impairments in subject suffering major depressive disorder. (R)
L-Theanine Promotes Relaxation without causing Drowsiness
Theanine is proving to be a great agent in promoting relaxation without the accompanying effect of drowsiness. The company developing ‘suntheanine’, l-theanine supplement, won the 1998’s Food Ingredient Research Award for the outstanding research and findings. (R)
L-Theanine Significantly Reduces Symptoms of Schizophrenia
In persons diagnosed schizophrenia receiving 400mg L-theanine in addition to antipsychotic medication for eight weeks were able to reduce anxiety as well as psychopathology symptoms significantly. (R)
L-Theanine Enhances Blood Flow and Stimulates Nitric Oxide Production
Theanine appears to promote nitric oxide formation at relatively low concentrations and is likely practically relevant following oral ingestion. (R)
Theanine and caffeine are typically found together in tea. A combination of caffeine and theanine together significantly improves alertness, reduce fatigue, and improves task-switching accuracy.
High dose caffeine (250 mg, equivalent to 2.5 cups of coffee) has some negative effects, such as jitters and increased blood pressure. Theanine was able to mitigate the increase in blood pressure.
“L-Theanine decreases the negative and jittery effects of caffeine in rats.
However, human studies found that L-Theanine helps reduce caffeine jitters, although the changes were not significant.
L-Theanine changes the pharmacological profile of caffeine in humans, as the combination of caffeine and L-Theanine have somewhat different cognitive enhancement effects. “- Selfhacked
Additional L-Theanine Benefits
Large studies in humans have not been undertaken; however, several smaller-scale studies (fewer than 100 participants) have shown increased alpha wave generation and lowered anxiety, along with benefits to sleep quality in people with ADHD. [R]
Mechanism of Action
How Does L-Theanine Work?
L-theanine has a comparable chemical composition to glutamate, an amino acid that assists in the transmission of nerve impulses in the brain. Thereby, providing a host of benefits for the mind. It has a remarkable ability of crossing the blood-brain barrier, which means that it reaches the brain directly. Furthermore, it has positive effects on stress levels proving to increase both dopamine and serotonin levels in brain; which are two of the brain’s feel-good chemicals. Green tea is known to be effective at helping people relax due to the positive impact on those neurotransmitters.
Theanine is an antagonist of the NMDA receptors (albeit with fairly weak efficacy) and can inhibit synaptic release of glutamate via blocking the transporter competitively. Theanine may also reduce glutamate levels, but this is also a fairly weak mechanism requiring a high concentration of theanine – Examine
How to Take L-Theanine?
The effective l-theanine dose is 200mg. For optimal nootropic results, take l-theanine with caffeine (coffee or supplement, whatever suits you) at a 2:1 ratio. As a stack, it would be:
For those interested, you can actually purchase a supplement pre-made that has 200 mg Theanine & 100 mg Caffeine pressed into one capsule. I’ve personally used and still use Nootropic Depot’s.
Note: if you have anxiety or hypertension, you may want to skip caffeine entirely as it aggravates the symptoms.
Experimenting is the best way to find out how you react to it.
What Are L-Theanine Side Effects?
L-theanine is very safe as very high doses have failed to cause toxicity. However, that doesn’t mean you should go for such high dosage. (R)
L-theanine is exceptionally reliable. Furthermore, it is classified Generally Recognized as Safe by the Fraud and Deception FDA in the US.
L-Theanine is a natural safe amino acid offering many benefits. It’s a popular choice for individuals wanting a simple and effective way to boost their mental performance. Alone, with caffeine, or even with an advanced nootropic stack; L-theanine is worth trying.
Frequently Asked Questions
What is L-Theanine and how does it work?
L-theanine is one of the main psychoactive constituents of green tea (camellia sinensis) generally used as a dietary supplement to promote relaxation, lift mood, and reduce anxiety without sedation. Beyond that, it’s been shown to generate creativity and higher learning via the ability to ignore distracting information during complex tasks. Now the science: L-theanine induces a calm state of mind by promoting alpha waves in the brain, and has been shown to increase dopamine, GABA, and glycine levels in various areas of the brain, as well as modulate BDNF (Brain derived neurotrophic factor) and NGF (Nerve Growth Factor) levels. In fact, in one recent animal study l-theanine consumption was associated with about a 25% increase in BDNF and about a 100% increase in NGF in the hippocampus. L-Theanine has structural similarities to glutamine and both neurotransmitters that are produced from it (GABA and glutamate) help balance and maintain stress levels while maintaining a state of wakeful relaxation. Lately, L-theanine has been growing in popularity due to its synergistic effects with caffeine to help boost focus. Systematic reviews show that L-theanine significantly mitigates the anxiety inducing side-effects of caffeine to create a balanced focus.
Should I take L-Theanine every time I drink coffee? Are there any adverse effects from long-term L-Theanine usage?
Yes, and no. Let me explain. L-Theanine is a phenomenal compound when mixed with coffee, due to the stacking of effect, as well as the reduction in some of the negative effects of caffeine itself. For example, in my biohacking course The Alchemist’s Guide To Biohacking, I talk about how I stack coffee blended with grass-fed butter, coconut oil, MCT, L-Theanine, macadamia or almond butter, and sometimes raw honey almost every single morning. It’s a part of my daily routine, and probably my most favourite (and definitely tastiest) part of it, if I have to choose one. However, like all compounds I take on a regular basis, I try to observe a 6/1 or 6/2 cycle with them, meaning six weeks on, then one or two weeks off, depending on the compound. This is to reduce dependency, as well as ensure my body isn’t getting used to the effects, resulting in me possibly having to take more. I’m currently in an off phase now with pine pollen, one of my go-to herbal supplements to boost my testosterone levels. With L-Theanine, I tend to take a week off at the same time I give myself a week off from coffee/caffeine, as it helps to do both at the same time for me.
Has anyone used L-Theanine as a meditation aid?
When you take L-theanine your thinking will seemingly slow down considerably, but you are not fully conscious when L-Theanine is in your bloodstream. It shuts off certain areas of the brain and limits the bandwidth of brain waves to predominantly alpha waves (1). Full meditative consciousness requires great brain wave bandwidth from delta – to high gamma waves and full activity of the neurotransmitter systems. It is best to meditate completely sober, then your brain will adapt properly to fully receive consciousness. Theanine is beneficial though, after it has metabolized by the body. It acts like an adaptogen and increases strength of brain. Your alertness increases 24 h after consumption and meditation is easier for 48 h. This is because brain have adapted to the presence of L-theanine, and once it has been metabolized, the brain neurons will fire with greater intensity, until brain is again adapted to absence of L-Theanine. L-theanine, a natural constituent in tea, and its effect on mental state.
Summary: N-Acetyl L-Tyrosine, often abbreviated to NALT, is a more bioavailable form of L-Tyrosine, an amino acid that also has nootropic benefits. It improves mood, memory, and enhances cognitive abilities in many ways. It has great effects of reducing stress and maintaining mental performance during sleep deprivation.
What is N-Acetyl-L-Tyrosine? (NALT)
Tyrosine is an amino acid the body produces from various dietary sources. Some of its primary functions are maintaining brain chemistry. A result of providing the necessities for the formation of dopamine, norepinephrine, and epinephrine; which are vital neurotransmitters that profoundly affect energy levels, moods motivation, and brain function. It works as the buffer delivering the necessary materials for the brain to produces them. Particularly under conditions where stress has depleted them. Another feature is its protein synthesis and the regulation of hormones required in the creation of melanin; supporting skin, hair, and eyes. Moreover, Tyrosine is related to the thyroid hormones.
It also supports weight maintenance and loss by suppressing appetite and helping the body’s ability to burn fats. Although the body produces sufficient amounts of L-Tyrosine on its own, studies suggest that additional supplementation provide physical and mental benefits especially under the circumstances of environmental stress.
N-Acetyl L-Tyrosine Enhances Cognition Under Stress
A recent study found that Tyrosine effectively impacts memory and information processing decline under stressors such as extreme weather or extreme cognitive demand. The study hypothesizes that this effect is because tyrosine grants substance from which the brain can produce neurotransmitters. Thereby neutralizing the depletes caused by stress. The report concludes that individuals are facing demanding requirements, whether mountain climbing or meeting job deadline, can benefit from L-Tyrosine. (R), (R)
Improves Memory Under Pressure and Challenges
A study investigating L-Tyrosine’s impact on individuals doing challenging mental tasks shows that those receiving L-Tyrosine perform better at the more difficult levels of the job. The study confirms L-Tyrosine to provide most benefits at higher levels of demand. (R)
Additionally, NALT is able to attenuate a decrease in memory formation associated with acute stressors
Increases Dopamine in the Brain and Boosts Cognitive Flexibility
A study of 22 individuals shows L-Tyrosine supplementation enhances cognitive flexibility as well as the ability to switch between tasks and thoughts. This result is attributed to L-Tyrosine’s capability to increase dopamine in the brain, which further enhances mental versatility.
Increases Focus and Supports ADHD Treatment
A study on ADHD patients shows 77% of participants receiving L-Tyrosine alone showed significant improvement over a period of 10 weeks. Further studies indicate that the simultaneous use of L-Tyrosine especially boosted the effect of ADHD medication such as Ritalin and Adderall. Non-ADHD nootropic users report that tyrosine improves focus. Therefore it is commonly added in nootropic stacks for that purpose. (R)
Mechanism of Action
How Does N-Acetyl L-Tyrosine Work?
L-Tyrosine forms in the body from a range of high dietary sources such as meats, fish, seeds, milk, yogurt, and cheese. It develops as a result of the precursor aminoalkanoic acid, known as essential amino acid, metabolizing within the liver. After metabolizing into L-Tyrosine, it further metabolizes by an associate protein known as hydroxylase, which prepares L-Tyrosine to be in use for the creation of different neurotransmitters. Once the protein hydrolyzes it, L-Tyrosine is carried in plasma and may metabolize into catecholamines in various membranes.
The discharge is activated by stimulation of adrenergic neurons within the brain, creating a restrictive interior system that maintains adequate internal secretion levels when the body is experiencing stress. Once there’s a high demand on the body’s stores of the vasoconstrictor, the brain responds with the release of adrenergic transmitters. The release, therefore, increases the quantity of the modifying protein discharged. A lot of L-Tyrosine transforms into catecholamines, thereby preventing deficits. This process is associating evidence in favor of L-Tyrosine supplement.
Once the discharge multiplies over a sustained amount, internal secretion synthesis is assumed to be addicted to concentrations of amino acid. Moreover, supplementation could increase internal secretion synthesis and unleash by making a certain sufficiency of amino acid throughout prolonged periods of stimulation.
How To Take N-Acetyl L-Tyrosine (NALT)?
The NALT dosage, however, is lower due to its higher bioavailability. With NALT, the typical daily dosage is 300 mg.
How To Take L-Tyrosine?
The standard L-Tyrosine dosage is 500-1000 mg daily, divided into 2 to 3 doses, half-hour before meals.
“Studies in humans showing most anti-stress promise for acute supplemental L-Tyrosine use a dosage range of 100-150mg/kg bodyweight which can be taken 60 minutes before exercise; this is a dosage range of 9-13.5g for a 200lb person and 7-10g for a 150lb person.
If using higher doses and finding digestive issues, this may be split into two doses separated by half an hour (30 and 60 minutes prior to acute stress).” as mentioned on Examine.com
L-Tyrosine is highly effective at improving cognition in situations involving intense stress. A robust body of research indicates that L-Tyrosine prevents cognitive decline in these situations. Furthermore, studies show that it enhances memory, increases cognitive flexibility, and improves mental performance under stress and cognitive demand.
The clinical studies, as well as anecdotal data from the nootropic community, indicate that L-Tyrosine is useful to everyone; not necessarily limited to those experiencing military-grade stress.
Working or studying long hours, struggling with anxiety, and even intense exercise are all stressors that impact cognition. Because L-Tyrosine is available through familiar dietary sources, supplementation is a choice rather than a health necessity. In situations that involve acute environmental stressors, it is a wise choice that will boost cognition. Therefore, tyrosine is worthy of consideration as a day to day supplement.
I have been taking l-tyrosine with some other amino acids and supplements every day 3 times a day for a while now. I take it bc I am on Adderall and Wellbutrin, so I like to give support to those systems they affect. I’ve had no side effects. I think they are doing great for my mood, but that could be the dl-phenylalanine, too.
I have been taking L-Tyrosine for 15 years or so as part of my ADHD stack. I do 500mg once a day 3-5 days a week. It can elevate anxiety levels and I find it seems to elevate norepinephrine more than dopamine based on my experience with other nootropics and meds. I notice if I go more than three or four days without it I start to feel foggy and don’t have the same level of mental clarity. But I take it with Taurine to take the edge off. If I take it for a couple of days without Taurine I also notice that it makes me a little edgy. It’s definitely a balance with this one.
Frequently Asked Questions
How does L Tyrosine help with fatigue?
The amino acid tyrosine (500 – 1000 mg each morning) is the raw material your body uses to make the neurotransmitters dopamine and norepinephrine. These both stimulate energy. There can be some immediate boost, but it takes six weeks to see the full steady-state effect
Does taking L-tyrosine supplements actually increase dopamine production in the brain?
A study of 22 individuals shows L-Tyrosine supplementation enhances cognitive flexibility as well as the ability to switch between tasks and thoughts. This result is attributed to L-Tyrosine’s capability to increase dopamine in the brain, which further enhances mental versatility.
Can L-Tyrosine ease depressive symptoms in a patient being treated for ADHD with stimulant medication?
Yes, it is helpful in relieving stress, building adrenaline stores, improving mood and in improving mental acuity. … Some studies show that children suffering from ADHD usually have low levels of Tyrosine. Both my sons take L-Tyrosine with their Adderall and Concerta respectively. I tried a lot of things before I finally let them try medication. Bingo! That was the magic bullet for them.
