L-Alpha Glycerylphosphorylcholine (Alpha-GPC), also known as GPC (glycerophosphocholine), is a naturally occurring phospholipid precursor and metabolite obtained from soy lecithin.
Alpha-GPC potentiates the effects of growth hormone releasing hormone (GHRH) and improves human growth hormone (hGH) secretion.
Furthermore, Alpha-GPC stimulates the enzymatic synthesis of phosphatidylcholine (PC) in nerves, leading to sharper mental focus and general cognitive improvement.
Alpha-GPC, as an acetylcholine (ACh) precursor, activates cholinergic transmission, allowing strength improvement from work-outs. In addition, it lowers levels of somatostatin in the hypothalamic-pituitary axis.
Finally, Alpha-GPC improves lipotrophic functions in the liver and enhances balance and coordination.
