D-Ribose is a natural pentose sugar that is the backbone of the ATP molecular structure, which supports the body's natural energy production. Corvalen® chewable tablets have a great-tasting, natural vanilla flavor, are sweetened with xylitol, and are convenient for on-the-go supplementation. ‡
D-ribose is a naturally occurring monosaccharide that is found in all cells and is involved in mitochondrial energy production. D-ribose is a substrate of the adenosine triphosphate (ATP) molecule, which is responsible for proper cell function and maintenance, including the synthesis of DNA and RNA. The pentose phosphate pathway (PPP) forms ribose-5-phosphate to ultimately produce ATP. This process is slow, as it requires a ratelimiting enzyme called glucose-6-phosphate dehydrogenase (G6PD). Alternatively, supplemental D-ribose may bypass the need for G6PD via purine metabolism, which occurs in the mitochondria. This process is more efficient, as it enables cells to efficiently reuse ATP metabolites to form new ATP molecules. ‡
D-ribose plays a critical role in energy metabolism by restoring and enhancing ATP concentrations. Clinical studies have shown that supplementation with D-ribose improved blood flow and enhanced the recovery rate of ATP synthesis, thus restoring cardiac energy metabolism. Following exercise, skeletal muscle ATP levels are depleted and may impact recovery time and subsequent performance. Supplemental D-ribose has been shown to restore tissue energy levels and improve recovery and performance in humans. The involvement of ribose in mitochondrial energy production may also indicate a supportive role of D-ribose in overall mitochondrial function and quality.‡

Mild, transient hypoglycemia may occur if taken on an empty stomach. Insulin-dependent diabetics and pregnant women should consult their physician before use. Ribose may cause a transient increase in uric acid levels; therefore, those that have chronic gout should consult their physician before use.
Store in a cool, dry place, away from direct light. Keep out of reach of children.
