Creatine is a natural energy source that is used in muscle and nerve tissue Creatine is stored as creatine phosphate (phosphocreatine) in muscle cells This phosphocreatine is the important factor that forms ATP (Adenosine Triphosphate), one of the body’s quick energy molecules Creatine replaces the ATP, which has been used up during muscle contraction, to allow prolonged intense activity Creatine Monohydrate supplementation increases phosphocreatine levels in the muscle, especially when accompanied by exercise or carbohydrate intake, therefore, forming an effective energy transfer system across cells
