    Alpha-GPC (alpha-glycerophosphocholine or choline alphoscerate) is a choline-containing phospholipid. When ingested, alpha-GPC is rapidly absorbed and easily crosses the blood-brain barrier. It is metabolized into choline and glycerol-1-phosphate. Choline is a precursor of acetylcholine, a neurotransmitter involved in memory, attention, and skeletal muscle contraction. Glycerol-1-phosphate is used to support cellular membranes.[1]
