Creatine Monohydrate is a naturally occurring 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 reservoir, especially during intense physical exertion. During short, intense bursts of activity, the body breaks down adenosine triphosphate (ATP) into adenosine diphosphate (ADP) 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. Creatine can also be stored for later use by cells, creating the “energy reservoir” active individuals desire.* NOW® Creatine Monohydrate is 100% pure and contains no additives or preservatives.
