Alpha ketoglutarate (AKG) is a precursor to glutamine and glutamate, which makes it a central fuel in various metabolic processes. Combined with ornithine, and amino acid, alpha ketoglutarate forms a salt (ornithine alpha ketoglutarate, or OKG) that is commonly taken by bodybuilders and athletes to help with muscle growth, endurance, and recovery. Alpha ketoglutarate is also available with arginine as L-arginine alpha ketoglutarate (AAKG). Alpha ketoglutarate, as OKG, works to increase energy, boost athletic endurance, and aid the muscles in exercise recovery.* OKG also promotes healthy skin, liver function, and brain function.** These statements have not been evaluated by the Food and Drug Administration.
