Iron Kingdom - Creatine Monohydrate - Unflavoured Creatine is a molecule found in animal meats, primarily red meats and fish. It's produced in the body from the amino acids arginine, glycine, and methionine, and serves a critical role in energy production during times of anaerobic, high energy demand on the body, such as intense movement like weightlifting, hockey, or sprinting. Creatine carries high-energy phosphate groups when it gets phosphorylated in the body into phosphocreatine and donates these phosphate groups to recharge ADP to ATP, the primary energy molecule in the body in the ATP-creatine phosphate system. Daily dosing of creatine is required to saturate the body with creatine to improve available phosphocreatine levels.
