Creatine is a metabolite found in the body, which is composed of 3 amino acids: 1-methionine, 1-arginine and 1-glycine. It is found in the skeletal system in 2 forms, creatine phosphate and free chemically unbound creatine. Creatine monohydrate has been clinically used in improving plasma creatine concentrations by as much as 50%. Creatine is found naturally in red meats and some types of fish. The biggest reason why creatine supplementation is necessary for some athletes is because the creatine content found in these foods is usually destroyed when cooking the meats. Supplementing with creatine allows the athletes to get the correct dosage and compensate for what is lost when cooking meats.
