Science-based nutritionDietary supplementSupports healthy energy levels in heart and muscle tissueMaintains normal heart functionDecreases free radical formation during exerciseRibose is an essential pentose (5-carbon) sugar utilized by the body to synthesize DNA, RNA and produce energy. Ribose is a fundamental building block of adenosine triphosphate (ATP the substance in which the body stores intracellular energy), the preferential source of energy for skeletal muscle and heart tissue. Studies have shown that ribose supplementation can enhance cardiac energy levels and support cardiovascular metabolism. Further studies suggest that ribose plays a role in supporting energy recovery after exercise. Exercise increases free radical production in muscle tissue. Ribose may strengthen and support the bodys crucial antioxidant defenses.
