Creatine Monohydrate is a naturally occuring compound found in the human body and obtained in the diet primarily from meat and fish. Creatine is a popular supplement among active individuals because of its ability to serve as an energy reservior, especially during intense physical exertion. During short, intense bursts of activity, the body breaks down adenosine triphosphate into adenosine diphosphate and phosphate for energy. Creatine helps the body convert ADP back to ATP, providing greater amounts of ATP for energy, which may increase short-term endurance and strength.
