D-Ribose is a five-carbon sugar found in every cell in our bodies that combines with oxygen and ATP (adenosine triphoshate) to give energy to each cell. Ribose is also present in RNA (ribonucleic acid), which is one of the main information carriers of living organisms.
Oxidative stress, is measured by free radical damage to cells. Fortunately, our bodies handle this problem daily. However, if our bodies experience an abnormal increase in free radicals due to exercise, daily stress, excess smoking, excess saturated fat intake, depressed immune system, aging, etc., the body becomes fatigued and less efficient in producing D-Ribose to replenish cellular energy. Because of this, we need to supplement with D-Ribose in order to regenerate the cells energy system.*
