INTRODUCTION

L-Alpha glycerylphosphorylcholine (alpha-GPC or choline alfoscerate) is a choline-containing phospholipid. When ingested, alpha-GPC 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.

Alpha-GPC appears to easily cross the blood-brain barrier and is rapidly absorbed. It is currently the best cholinergic for increasing plasma and brain choline levels.

Manufacture
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.

Structure

Applications

Alpha-GPC is a prescription medication for the treatment of Alzheimer s disease. It is available in two forms; one is taken by mouth, and the other is given as a shot. In the United States alpha-GPC is only available as a dietary supplement, mostly in products promoted to improve memory.
Alpha-GPC include treatment of various kinds of dementia, stroke, and “mini stroke” (transient ischemic attack, TIA).
Alpha GPC rapidly delivers choline to the brain across the blood–brain barrier and is a biosynthetic precursor of the acetylcholine neurotransmitter.
