Ribose 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 body's crucial antioxidant defenses.

Research suggests that optimal heart function requires a consistent supply of essential cofactor nutrients including CoQ10, D-ribose, L-carnitine and Magnesium. Consider these other high quality Doctor's Best products in combination with Best D-Ribose for enhanced cardiovascular support: High Absorption CoQ10, High Absorption Magnesium, Best L-Carnitine Fumarate.

A good high dose D-Ribose

Posted by iHerb Customer on July 13 2017 | Verified Purchase

We started taking D-Ribose for two reasons. 1. To alleviate muscle pain after exercising and 2. because it was recommended for heart health by a respected heart doctor. We have found that it stops muscle pain and the muscles recover much faster and it is also brilliant if the heart acts up with irregular heart beat because that can cause the heart muscle to become sore after doing more work. It works to heal the heart muscle fast.
