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.

This is my first order and I had already received the goods of my third order without any problem. I would say iherb is simply the best. I fully recommend to use the iherb service. Regarding the supplements, we start to use a few weeks ago and I think it is too early to make a comment.

I need the D-Ribose to give to my dog with congestive heart failure as a supplement. Doctor's best at iherb is the only one I could find that carries the exact dosage I need for her. It's always delivered very fast so I never have to worry about her running out before it gets here. Also, it's been close to a year since she's been diagnosed and not only is she still with me but her veterinarian is always amazed at how well she's doing so it's obviously doing it's job. Thanks so much.
