Creatine-alpha ketoglutarate

Creatine-alpha-ketoglutarate is a salt formed from alpha-ketoglutaric acid (AKG) and creatine. It is sold as a fitness supplement; however, its effects are experimentally unproven.[1]

Creatine is a mass-produced fitness supplement that is supposed to increase the user's muscle mass, strength and power. Arginine alpha-ketoglutarate itself is a chemical compound that is supposed to increase the blood flow to muscles and therefore, increasing nutrient delivery to muscle cells.[2]
