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

• D-Ribose with Magnesium and Malate
• Support for fatigue, energy production and mitochondrial function*

Corvalen M contains pure D-ribose, a clinically researched ingredient that supports the natural way our bodies produce adenosine triphosphate (ATP), the energy currency of the cell.* 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.*

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 to 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.
