Alpha-GPC (L-Alpha-Glycerylphosphorylcholin)
Overview
Alpha-GPC (L-alpha-glycerylphosphorylcholine) is a natural choline compound containing 41% choline by weight, efficiently crossing the blood-brain barrier as a superior acetylcholine precursor. A comprehensive review confirmed bioactivity across cognitive, cardiometabolic, and anti-aging applications. Generally well tolerated at standard doses (300–600 mg/day). As a choline compound, high doses carry TMAO-related cardiovascular concerns. Possible interaction with cholinesterase inhibitor medications.
