Creatine, when either synthesized by the body or consumed through meats or supplementation, is readily absorbed through the small intestine and delivered by the bloodstream and stored in muscles where creatine begins to exert its many benefits. Creatine is stored in human body as a compound known as "phosphocreatine", which further works as a reservoir of phosphate. Phosphocreatine is a substance that stores energy in the muscular tissues and provides energy for the muscular contractions. Phosphate produced from creatine is needed for regenerating adenosine triphosphate (ATP) molecules, which is the main fuel for your body during high intensity situations like weightlifting or other sports.
