D-Ribose is the material from which ATP (Adenosine Triphosphate) is made. D-Ribose boosts energy, endurance and enhances muscle recovery. In addition it is thought to work synergistically with creatine to give added value, with increased muscle health and fitness. As a dietary supplement, D-Ribose provides its benefits by giving the cells the fuel they need to rapidly increase ATP levels, and thus restore energy levels throughout the body for long periods of time.
