L-alpha glyceryl phosphorylcholine (Alpha GPC) is a form of choline that’s concentrated in brain cell membranes. It helps to synthesize the neurotransmitter acetylcholine and forms part of the phosphatidylcholine that’s used in building cell membranes.

It also freely crosses the blood-brain barrier to directly support acetylcholine production making it the ideal choline supplement. UK made to high quality GMP standards.

Product Description

Aliness Buy alpha GPC europeis a dietary supplement that provides a potent source of highly absorbable choline in the form of L-alpha glycerylphosphorylcholine (alpha-GPC). This naturally occurring phospholipid is found concentrated in key brain cell membranes and acts as a building block for the neurotransmitter acetylcholine, which plays an important role in memory, learning and mental acuity.

In clinical trials, alpha-GPC has been shown to stimulate the release of acetylcholine and boost learning and memory. It also may improve muscle strength and endurance, including during high-intensity training.

Alpha-GPC is non-GMO and vegan, containing no animal ingredients. It is manufactured in the UK to GMP standards, ensuring the highest quality. It is part of the Nootropics Depot line of products and is recommended for intellectually active individuals who seek to maintain concentration, clarity of mind and motivation to act. Each capsule contains 300 mg of choline alfoscerate, derived from the rainforest plant uncaria tomentosa. It does not contain any artificial technological additives, preservatives or dyes.


L-Alpha glycerylphosphorylcholine (abbreviated Alpha GPC) is a naturally occurring choline compound that is found concentrated in important brain cell membranes. It is a precursor in the synthesis of phosphatidylcholine, an important neurotransmitter that plays a role in memory, focus and REM sleep states.

A water-soluble choline supplement, Alpha GPC readily crosses the blood-brain barrier and is absorbed directly into brain tissue. This makes it one of the most effective choline sources available. It also promotes healthy acetylcholine levels, which enhances neuronal communication and supports cognitive function.

Contains: cellulose powder, magnesium silicate, stearic acid (vegetable source), pharmaceutical glaze, silica.

Nootropics Depot’s Alpha GPC 50% Powder is a high quality, GRAS-affirmed product that is manufactured in the USA. It has been shown to improve memory and attention, while enhancing the ability to process information quickly. It also appears to support cellular membranes and may help prevent the degeneration of neurons that occurs with age. It is also used as a nootropic to increase power output during intense exercise and to reduce muscle fatigue.


Buy alpha GPCis a water-soluble choline supplement that easily crosses the blood brain barrier and is absorbed by cells. It serves as a precursor for the neurotransmitter acetylcholine and is thought to support cognitive function, including memory and focus.

It also appears to stimulate the production of phosphatidylcholine in neurons, which can increase strength and encourage the release of human growth hormone (hGH). Studies on humans show that alpha GPC may help reduce age-related mental decline and improve athletic performance.

A 1994 study found that a-GPC enhances overall brain health by promoting the cholinergic system, which handles cognitive functions like memory recall and thinking. It is a preferred source of choline for nootropic users because it is less likely to cause side effects, such as fatigue or gastrointestinal upset, than CDP choline. It also contains the essential B vitamin folic acid.

Side Effects

Alpha GPC is a choline-containing compound that supports the brain’s ability to synthesize acetylcholine, a neurotransmitter involved in memory and focus. It also promotes healthy cell membranes and increases dopamine levels. It is considered a nootropic and is often stacked with piracetam and other cognition-boosting compounds.

Alpha-GPC is a more stable form of choline that can pass through the blood-brain barrier easier than other forms of choline. It may be beneficial for people with epilepsy because it protects neurons and may boost cognitive function in these individuals (Lee, 2017).

However, the scientific evidence supporting alpha-GPC’s benefits is limited and mostly from animal studies and small clinical trials. More research is needed to establish whether it is a reliable nootropic for improving mood and concentration. Moreover, it is not suitable for children and pregnant women. It can also irritate the stomach.
