Alpha-GPC

L-Alpha glycerylphosphorylcholine (alpha-GPC, choline alfoscerate) 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]

Research

An Italian multicentre clinical trial on 2,044 patients suffering from recent stroke were supplied alpha-GPC in doses of 1,000 mg/day for 28 days and 400 mg three times per day for the five ensuing months. The trial confirmed the therapeutic role of alpha-GPC on the cognitive recovery of patients based on four measurement scales, three of which reached statistical significance.[5]

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 from purified sunflower lecithin.
