L-a-Glycerylphosphorylcholine (Alpha GPC) (CAS No 28319-77-9). L-Alpha glycerylphosphorylcholine (alpha-GPC, choline alfoscerate) is a natural choline compound found in the brain. It is also a parasympathomimetic acetylcholine precursor which may have potential for the treatment of Alzheimer's disease and other dementias.
Alpha-GPC rapidly delivers choline to the brain across the blood–brain barrier and is a biosynthetic precursor of acetylcholine. It is a non-prescription drug in most countries and in the United States it is classified as generally recognized as safe (GRAS).
