The following doses have been studied in scientific research:
ADULTS
BY MOUTH:
- For clogged heart arteries (coronary artery disease): 60 grams daily for 3 days has been taken under the direction of a healthcare provider.
- Congestive heart failure (CHF): 5 grams three times daily has been taken for up to 8 weeks.
INTRAVENOUS (THROUGH THE VEIN):
- For clogged heart arteries (coronary artery disease): A 10% ribose solution may be given at a dose determined by a healthcare provider. *
We don't yet have a standard dosing recommendation for d-ribose supplements. In the study on fibromyalgia and chronic fatigue syndrome, participants took five-gram doses three times a day.
In some studies of d-ribose for people with heart failure, researchers have used doses of 15 grams four times a day.
D-ribose supplements are widely available. They are typically sold in powder form. *
