D-Ribose, a monosaccharide sugar found in all living cells, plays a critical role in cellular metabolic pathways that generate energy. D-Ribose supports normal heart muscle function and may also support normal skeletal muscle function during exercise and in people with certain muscular dystrophies or fibromyalgia. As a fundamental constituent of adenosine triphosphate (ATP), D-ribose is essential for normal energy production. It is also a component of nucleotides, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). D-ribose is only found in small amounts in the diet. The body must synthesize D-ribose from glucose. Cardiac muscle is especially vulnerable to conditions that deplete ATP and nucleotide pools. It may take days for ATP levels to be restored after strenuous exercise or ischemia as both cardiac and skeletal muscle have low levels of enzymes needed to convert D-ribose to D-ribose-5-phosphate, the activated form of D-ribose that plays a critical role in regenerating cellular ATP. D-Ribose administration has been shown to significantly accelerate restoration of heart ATP levels, especially in the setting of inadequate blood flow to the heart muscle and diminished exercise capacity. Pure D-Ribose is supplied in powder form for convenient supplementation of multi-gram amounts found to be beneficial.
D-Ribose powder has a natural, slightly sweet taste and mixes readily in water or juice.
