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.
