alpha-GPC, aka alpha-glycerylphosphorylcholine, is a naturally occurring alkaloid and a prodrug for choline. It is a metabolic intermediate in the biological production of the neurotransmitter acetylcholine, as well as phosphatidylcholine (which is a phospholipid used by the body in the creation of cellular membranes). It is produced naturally in the human body from choline itself. Alpha-GPC is a bioavailable prodrug and can elevate endogenous levels of choline. Each mole of alpha-GPC metabolizes into equimolar ratios of choline, phosphate, and glycerol.

Placebo controlled, human clinical trials demonstrate alpha-GPC to be effective in alleviating symptoms of cognitive decline in patients with Alzheimer’s disease, cerebral ischemia, vascular dementia, and stroke [3]. Choline (as well as its prodrugs) can reduce the risk of neural tube defects in pregnant women [4] [5], and low-choline diets are associated with pre-eclampsia, premature birth, and low birth weight [1]. In healthy subjects, alpha-GPC (supplemented alongside caffeine) has been shown to improve test scores and reaction times during acute stress [6].

A human clinical trial conducted by MiT professor Richard Wurtman found that choline, in combination with docosahexanoic acid (an omega-3 fatty acid from fish oil) and uridine (a nucleoside from RNA) consistently alleviated symptoms of Alzheimer's in diagnosed patients [7].
