Alpha GPC, also known as L-Alpha glycerylphosphorylcholine, is a unique and naturally occurring choline compound in the brain. Alpha GPC has been shown to increase levels of acetylcholine in the brain via its ability to cross over the blood-brain barrier, where it becomes metabolized into choline, a precursor to Acetylcholine. -In addition to this, Alpha GPC has been found to increase levels of dopamine within the cerebellum and frontal cortex. This naturally occurring choline source does not only have significant nootropic properties but has been shown to enhance cell membrane health, improve physical recovery and increase in somatropin, or HGH, production.
