D-Ribose Powder 10.58 oz (300 grams) by Klaire Labs

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 and skeletal muscle function.^† As a fundamental constituent of adenosine triphosphate (ATP), D-ribose is essential for normal energy production. It is also a component of the nucleotides DNA and RNA. 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 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 support heart ATP levels, especially in the setting of 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.
