Description
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, L0carnitine 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 L0Carnitine Fumaraate.

Health Notes

Ribose

Ribose
This nutrient has been used in connection with the following health goals
  • Reliable and relatively consistent scientific data showing a substantial health benefit.
  • Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
  • For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary "Star-Rating" system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

This supplement has been used in connection with the following health conditions:

Angina
Dose: Refer to label instructions
In one study, men with severe coronary heart disease who took ribose were able to exercise significantly longer than those taking placebo before experiencing chest pain and before abnormalities appeared on their electrocardiogram (ECG).(more)
Athletic Performance
Dose: Refer to label instructions
Ribose is a type of sugar used by the body to make the energy-containing substance adenosine triphosphate (ATP), which gets depleted during intense exercise. Reports have suggested that taking ribose might increase power during short, intense bouts of exercise.(more)
Angina
Dose: Refer to label instructions

In a controlled study, men with severe coronary heart disease were given an exercise test, after which they took either 15 grams of ribose or a placebo four times daily for three days. Compared with the initial test, men taking ribose were able to exercise significantly longer before experiencing chest pain and before abnormalities appeared on their electrocardiogram (ECG), but only the ECG changes were significantly improved compared with those in the placebo group.1 Sports supplement manufacturers recommend 1 to 10 grams per day of ribose, while heart disease patients and people with rare enzyme deficiencies have been given up to 60 grams per day.

Athletic Performance
Dose: Refer to label instructions

Ribose is a type of sugar used by the body to make the energy-containing substance adenosine triphosphate (ATP). Intense exercise depletes muscle cells of ATP as well as the ATP precursors made from ribose,1, 2 though these deficits are typically replaced within minutes.3 Unpublished reports suggested that ribose supplementation might increase power during short, intense bouts of exercise.4, 5 However, in a double-blind study, exercisers took four grams of ribose four times per day during a six-day strength-training regimen, and no effects on muscle power or ATP recovery in exercised muscles were found.6 In two other controlled studies, either 10 grams of ribose per day for five days or 8 grams every 12 hours for 36 hours resulted in only minor improvements in some measures of performance during repetitive sprint cycling.7, 8
