Arginine alpha-ketoglutarate (AKG) is a salt formed by combining two molecules of the amino acid L-Arginine and one molecule of alpha-ketoglutarate.L- Arginine is a nonessential amino acid that influences several metabolic factors that are important to athletes. AKG (alpha-ketoglutarate) is the nitrogen-free portion of the amino acids known as glutamine and glutamic acid. It is formed in the Krebs cycle; the energy-producing process that occurs in most body cells. AKG is used by cells during growth and in healing from injuries and other wounds and is especially important in the healing of muscle tissue.
The alpha-ketoglutarate version of arginine is more efficient. When you combine these two things it's more easily absorbed, plus you get the benefits of both compounds. This combination has been shown to boost insulin in healthy men and help small children grow faster. So not only will it improve your blood flow but it also boosts your hormones and makes you grow faster.
