Corvalen M ® D-ribose, is a natural pentose sugar that is designed for the support of fatigue, energy production, and mitochondrial functionニ. Magnesium and malate are added to this formula to help in the utilization of energy and support symptoms of fatigue.


Corvalen M® contains pure D-ribose, a safe and clinically researched ingredient that supports the natural way our bodies produce adenosine triphosphate (ATP), the energy currency of the cell. Ribose is the vital structural backbone of critical cellular compounds called purines and pyrimidines. Our bodies must have an adequate supply of purines and pyrimidines to form major cellular constituents such as our genetic material (DNA and RNA), numerous cofactors, certain vitamins, and, importantly, adenosine triphosphate (ATP).

Ribose is the starting point for the synthesis of these fundamental cellular compounds, and the availability of ribose determines the rate at which they can be made by our cells and tissues. D-ribose is a structural component of DNA, RNA, ATP, GTP, flavins (FAD, riboflavin) and other important nucleotides found in all living cells.

Purine nucleotides (ATP and its precursors) lost due to ischemia, hypoxia, or genetic predisposition are replaced via the purine nucleotide pathway. This pathway is rate limited by the availability of ribose in tissue.

A deficiency of ATP energy in the cell, also called mitochondrial dysfunction, can lead to symptoms of occasional muscle pain, fatigue, sleep disturbances, and brain fog.

A study performed on 41 patients with symptoms of fatigue and muscle pain resulted in approximately 66% of patients experiencing significant improvement while on D-ribose, with an average increase in energy on the visual analog scale of 45%, and an average improvement in overall well-being of 30%.

Malic acid is a naturally occurring organic acid and an important intermediate in the Krebs cycle, acting as an electron donor to the phosphorylization reactions in the mitochondria. Magnesium is critical in facilitating hundreds of biochemical reactions including those involved in energy production.

Although D-ribose is a five-carbon monosaccharide, it does not raise blood sugar. Corvalen M® D-ribose is highly soluble in both hot and cold solutions and tastes slightly sweet and tart.

Corvalen M® D-ribose is non-GMO. D-ribose is rapidly and readily (~95%) absorbed with peak blood levels found within 30 ヨ 45 minutes. Ribose not taken up by the cell is excreted unchanged in the urine. Corvalen® D-ribose is GRAS (generally recognized as safe), a determination that results only after considerable toxicology studies are performed by the FDA.

Corvalen M® D-ribose is a useful dietary supplement for those patients that want to restore energy and support the symptoms of fatigue with the added benefit of magnesium and malate to help relieve occasionally sore muscles.
