Ribose is a naturally occurring five carbon sugar found in all living cells. Ribose is very essential for life, since some of the most important biological molecules in the body contains ribose, such as ATP (adenosine triphosphate, all the nucleotides and nucleotide coenzymes and all forms of RNA (ribonucleic acid).* Ribose supplementation has been shown to enhance the rate at which ATP is replenished in skeletal muscle tissue, decreasing recovery time from exercise dramatically. * Physicians Desk Reference for Nutritional Supplements, pp 139-41.
