Creatine is part of the ATP process that energizes muscles on a cellular level. During exercise the body will eventually exhaust its naturally produced creatine supply, forcing the ATP process to slow down and cause muscles to begin to tire. Supplementing the ATP process with orally consumed creatine ultimately encourages longer periods of training and heavier lifts. The most common side-effect of creatine monohydrate is water retention in muscle tissue causing a bloated appearance.
