Arginine-alpha-ketoglutarate, also known as AAKG, is a salt of the amino acid arginine and alpha-ketoglutaric acid and is a precursor to nitric oxide production.
Basically, the arginine, which is known as essential amino acid is necessary for the production of creatine, it increases blood flow to the muscles.
While alpha-ketoglutarate (AKG) is known as an intermediate to generate the energy through the transamination of glutamate. Also, the AKG has antioxidant properties.
Therefore, AAKG, by increasing the blood flow in muscles, can ensure that muscles have energy during all the training. And is necessary to increase the nitric oxide production in body, as better workout with higher levels of nitric oxide may help to promote greater levels of muscle mass and greater energy.
