Alpha-GPC (Alpha-glycerophosphocholine or sometimes just glycerophosphocholine) is a Choline-containing supplement.
Alpha-GPC also appears to support the structure of cellular membranes, which is not a common mechanism attributed to choline prodrugs (only CDP-choline is associated with lipid membranes in this sense).
Alpha-GPC seems to increase a chemical in the brain called acetylcholine. This brainchemical is important for memory and learning functions.
Oral supplementation of alpha-GPC is of interest for nootropic purposes, as it appears to have cognitive-enhancing properties and attenuate the rate of cognitive decline in the elderly. Athletes are at times interested in alpha-GPC due to its ability to enhance growth hormone production.
Use under Medical supervision.
