What is Alpha-GPC?
Alpha-GPC (alpha-glycerophosphocholine) is a cholinergic compound praised for its cognitive-promoting properties. Alpha-GPC may aid in preventing cognitive decline by supporting cellular membranes. Additionally, it is sometimes used to stimulate bursts of energy in athletes, and it is perfect for stacking with other nootropics in order to create powerful synergies. This compound naturally occurs in our brain and can be found in several food groups such as eggs, fish, meat, and dairy. Studies have shown that using Alpha-GPC as a dietary supplement can improve both physical and cognitive performance by affecting growth-hormone in healthy adults. It also aids brain health by supporting its structure and when taken as a supplement. Alpha-GPC has a nootropic effect which can be considered similar to that of caffeine.
Choline is an essential nutrient that can be found in some animal food groups such as organ meat, eggs, fish, and dairy. Choline is used broadly for metabolism in the body, with functions like aiding in cell structure through the creation of phospholipids and producing acetylcholine, an important neurotransmitter that plays a key role in mood, memory and muscle control, gene expression and brain development. Studies have shown that using Alpha-GPC as a dietary supplement can improve both physical and cognitive performance by affecting growth-hormone in healthy adults. As a nootropic, Alpha-GPC has a stimulating effect similar to that of caffeine and can mitigate common side effects, such as headache, resulting from the use of -racetams.

Alpha-GPC Guidelines
Alpha-GPC dosage: As a dietary supplement, take 1 – 2 capsules per day.
Effect onset: 60 – 120 minutes
Effect duration: Peak effect duration of 1 – 3 hours.
Extended use: Safe for extended use, it is non-addictive, is not known to cause harm, and has an extremely low toxicity relative to dose.
Usage notes:
- Alpha-GPC is not habit-forming and the desire to use it can actually decrease with use. It is most often self-regulating.
- Tolerance to the effects of Alpha-GPC is built after prolonged and repeated usage. It takes about 7 days for the tolerance to be reduced to half, and 14 days to be back at baseline.
- It stacks well with other nootropic supplements.
Alcohol note: Alpha-GPC presents cross-tolerance with no other known compounds, meaning that after the use of Alpha-GPC all other psychoactive compounds will not have a reduced effect.
Caution: Alpha-GPC and MAOIs (Monoamine Oxidase Inhibitors) are a potentially dangerous combination. It is likely that MAOIs could increase the effects of Alpha-GPC unpredictably. Taking this chemical while on MAOIs prescription is strongly discouraged. Please talk to your doctor about this.
