Creatine is a naturally-occurring amino acid (protein building block) that's found in meat and fish, and also made by the human body in the liver, kidneys, and pancreas.It is converted into creatine phosphate or phosphocreatine and stored in the muscles, where it is used for energy.ost studies have found no significant side effects at the doses used for up to 6 months. Rhabdomyolysis (breakdown of skeletal muscle tissue) and sudden kidney failure was reported in one case involving an athlete taking more than 10 grams daily of creatine for 6 weeks.
