Arginine Alpha-Ketoglutarate (AAKG) is the main ingredient in most popular cell volumisers. The combination of Alpha-Ketoglutarate with Arginine helps improve amino acid synthesis and both Arginine and AKG may improve protein availability.
Arginine is a precursor for Nitric Oxide (NO2) a very powerful vasodilator that increases the intensity and duration of the "pump" when working out with heavy weights. In men with low urinary nitric oxide values l-arginine may support healthy sexual function.
Although more studies are needed research suggests that Arginine supports healthy endothelial function in blood vessels of healthy males. It has been shown to support healthy lipid metabolism. Arginine also plays a role in the synthesis anabolic hormones such as insulin and growth hormone.
