Benefits of Alpha Glycerophosphocholine

  1. Increase human growth hormone (HGH)
    The anterior pituitary, in combination with growth hormone releasing hormone (GHRH), boosts the secretion of endogenous human growth hormone (hGH). In other words, Alpha - GPC and GHRH cooperate to naturally stimulate the release of hGH.

  2. Improve mental focus and stimulate cognitive function
    It stimulates the enzymatic synthesis of phosphatidylcholine (PC) in nerves, muscle cells, and all cell membranes, offsetting the decline in age - related phospholipid (PC) biosynthesis. Thus, Alpha - GPC directly helps improve mental concentration and stimulates cognitive function.

  3. Get more power through exercise and training programs
    It serves as a precursor of Acetylcholine (ACh). As a result, Alpha - GPC activates cholinergic transmission, thereby providing greater strength for exercise and training programs and reducing the level of somatostatin in the hypothalamic - pituitary axis.

  4. Improve liver's fat nutrition function
    An increase in the levels of the essential nutrient choline in the blood and tissues can enhance the fat nutritional function (methyltransferase) in the liver. Studies have indicated that fatty liver associated with obesity, diabetes, and heavy alcohol consumption often leads to cirrhosis or liver failure. Research carried out by Alan L. Buchman (M.D.), an associate professor of medicine at Northwestern University's Feinberg School of Medicine, shows that elevated choline levels can prevent or even eliminate fatty liver. Alpha - GPC also works in synergy with the body's S - adenosyl - L - methionine (SAM or SAMe) and the storage (and/or supplementation) of folic acid, vitamin B12, and vitamin B6 to promote the transfer of methyl groups in the brain and liver.
