The chemical compound alpha-glycerophosphocholine (alpha-GPC) has choline-containing properties and can be used to increase the brain and body's levels of choline.


In this role it serves as a precursor for both acetylcholine and phosphatidylcholine biosynthesis.


The nootropic forms of choline are alpha-GPC and citicoline (i.e., CDP-choline). They increase brain choline levels, act as building blocks of acetylcholine, and support choline-dependent neurotransmission.


Alpha-GPC, however, contains a higher proportion of choline, so a lower dose of alpha-GPC provides more choline support than a similar dose of citicoline.

Alpha-GPC is therefore more effective by weight as a choline precursor. Alpha-GPC is metabolized into choline and phospholipid glycerophosphate following oral administration.


Acetylcholine is a key neurotransmitter in the brain; it's also used in the flight or fight response of the autonomic nervous system; and it is a signaling molecule that activates muscles.[3,8–13] Choline can be used to synthesize acetylcholine and to transmit it through neural pathways.


Because alpha-GPC is a precursor in the biosynthesis of acetylcholine, it plays a supportive role in a variety of cognitive functions, including attention, concentration, mental focus, and memory formation and recall.[15]*


Alpha-GPC also supports aspects of muscle performance, and is involved in maintaining organs and tissues.* And, because alpha-GPC can be readily metabolized into phosphatidylcholine, it can be used to support the structure and function of cell membranes. Alpha-GPC is found in low amounts in a variety of foods[16] and in breast milk.[17,18] effects [2–5].
