L-α-Glycerophosphorylcholine (alpha-GPC, choline alfoscerate, sn-glycero-3-phosphocholine) is a natural choline compound found in the brain. It is also a parasympathomimetic acetylcholine precursor[1] which has been investigated for its potential for the treatment of Alzheimer's disease[2] and other dementias.[3]

Alpha-GPC rapidly delivers choline to the brain across the blood–brain barrier and is a biosynthetic precursor of acetylcholine.[2] It is a non-prescription drug in most countries. The FDA determined that intake of no more than 196.2 mg/person/day is considered generally recognized as safe (GRAS).[4]

Production

Industrially, alpha-GPC is produced by the chemical or enzymatic deacylation of phosphatidylcholine enriched soya phospholipids followed by chromatographic purification. Alpha-GPC may also be derived in small amounts from highly purified soy lecithin as well as from purified sunflower lecithin.[5][6]
