D Ribose is a natural 5 carbon sugar found in all living cells. The body naturally produces d ribose, which begins the metabolic process for cellular energy production via adenosine triphosphate (ATP). The production of ATP, either through the synthesis of new energy or via the salvage pathway of energy preservation, is rate-limited by the availability of d ribose. d-Ribose supplementation can support increased metabolic demands, reduce exercise recovery time, improve cardiac function, improve muscle recovery, reduced muscle stiffness, soreness, and fatigue post exercise. *
