InosineSkip to the navigation
Inosine is a nucleoside, one of the basic compounds comprising cells. It is a precursor to adenosine, an important energy molecule, and plays many supportive roles in the body.
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.
3 Stars Reliable and relatively consistent scientific data showing a substantial health benefit.
2 Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1 Star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
This supplement has been used in connection with the following health conditions:
Refer to label instructions
Inosine is a precursor to uric acid, which is believed to block the effect of a compound that may play a role in MS development. Patients given inosine in order to raise uric acid levels experienced improved function in one study.
Inosine is a precursor to uric acid, a compound that occurs naturally in the body. Uric acid is believed to block the effect of a toxic free-radical compound (peroxynitrite) that may play a role in the development of multiple sclerosis.1 In an attempt to raise uric acid levels, ten patients with MS were treated with inosine in amounts up to 3 grams per day for 46 weeks. Three of the ten treated patients showed some evidence of improved function and the others remained stable.2 Controlled studies are needed to confirm these preliminary results.
How It Works
How to Use It
Although a common amount of inosine taken by athletes is 5,000–6,000 mg per day, little scientific evidence supports the use of this supplement in any amount.
Where to Find It
Inosine is found in brewer’s yeast and organ meats. It is also available as a supplement.
Inosine is not an essential nutrient, so deficiencies do not occur.
Interactions with Supplements, Foods, & Other Compounds
Interactions with Medicines
No side effects have been reported with the use of inosine for two to five days in the limited research available. However, unused inosine is converted by the body to uric acid, which may be hazardous to people at risk for gout.
