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 and/or minimal health benefit. | |
How much is usually taken?
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.
Are there any side effects or interactions?
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.
