L-Alpha Glycerylphosphorylcholine (Alpha GPC, choline alfoscerate) CAS NO.: 28319-77-9  is a natural choline compound found in the brain and in milk. It is also a parasympathomimetic acetylcholine precursor which may have potential for the treatment of Alzheimer's disease and is used as a nootropic dietary supplement to enhance memory and cognition.
L-α-glycerophosphatidylcholine (GPC) is the simplest phospholipid, and an intermediate metabolite in the choline pathway. In addition, GPC serves as an organic osmolyte in the kidney and may play a role in sperm motility. In diet, it is normally presented in low amounts,

 
Alpha GPC 28319-77-9 increase a chemical in the brain called acetylcholine. This brain chemical is important for memory and learning functions
 
 
In Europe 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.Other uses for alpha-GPC include treatment of various kinds of dementia, stroke, and “mini stroke” (transient ischemic attack, TIA). Alpha-GPC is also used for improving memory, thinking skills, and learning.
 
Alpha GPC rapidly delivers choline to the brain across the blood–brain barrier and is a biosynthetic precursor of the acetylcholine neurotransmitter. Alpha GPC is derived from highly purified soy lecithin.
 
Alpha GPC or GPC has been documented extensively by published studies in both
animals and humans to contribute to at least five (5) signt human health functions.
