Alpha-GPC (L-alpha-glycerylphosphorylcholine) is a choline compound, a water-soluble derivative of phosphatidylcholine that carries a choline group, and the Celyfe compound library files it as a choline precursor studied in acetylcholine synthesis. It is not carried in any Celyfe pen.
What is Alpha-GPC?
Alpha-GPC is glycerophosphocholine: a glycerol backbone joined through a phosphate to choline, without the two fatty-acid chains that make phosphatidylcholine a membrane lipid. That makes it a small, water-soluble choline carrier. The Celyfe library classes it as a choline compound with an oral delivery route and the mechanism note: choline precursor studied in acetylcholine synthesis. Acetylcholine is a neurotransmitter built from choline, which is the textbook reason a choline compound sits in a cognitive layer. It is not a peptide and not a regulated compound.
Is Alpha-GPC in a Celyfe pen?
No. The closest relative in a pen is phosphatidylcholine, the phospholipid carrier in the NAD+ Precision Pen vehicle, which shares the choline head group but is a different molecule. Alpha-GPC is not in any of the four pens, Celyfe does not currently sell it as a product, and Celyfe lists no Alpha-GPC reference, so this page makes no statement about research findings.
