Product Information Menu
Clinical research in humans and animals has demonstrated that GPC (L-alpha-glycerylphosphorylcholine) helps support higher brain function, mental acuity, and the release of human growth hormone. L-alpha-glycerylphosphorylcholine is a precursor to the neurotransmitter acetylcholine and the membrane constituent phosphatidylcholine. Research suggests that it is more bioavailable than other forms of choline for the maintenance of learning and memory.
