l-Alpha-glycerophosphatidylcholine (GPC-choline, alpha-GPC) is a water-soluble phospholipid metabolite naturally occurring in the body. Alpha-GPC passes through the blood brain barrier providing a source of choline for acetylcholine and phosphatidylcholine biosynthesis. An open, multi-center clinical trial involving 2,044 subjects indicated that alpha-GPC supports cognitive health and has excellent tolerability. Research suggests that alpha-GPC plays a role in enhancing mental function, neurological function, and memory. In a multicenter, randomized, controlled study, 261 subjects supplemented with alpha- GPC demonstrated improved neuropsychological parameters in behavioral scales and tests.
Alpha-GPC is an important neurotransmitter and phospholipid precursor providing support for age-related decline in cognitive function, memory, and cerebrovascular health.
