Inosine is a chemical that is found in RNA, which is present in all living cells. It can be made in a laboratory and is also used as medicine.

When people take inosine by mouth it is changed in the body to make a chemical called uric acid. Uric acid acts like an antioxidant and might protect cells in the brain.

People use inosine for Parkinson disease, multiple sclerosis (MS), athletic performance, and many other conditions, but there is no good scientific evidence to support these uses.
When taken by mouth: Inosine is possibly safe. Taking inosine can cause high levels of a chemical called uric acid in the blood and urine. This might cause kidney or bladder stones in some people.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if inosine is safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.

Gout: Taking inosine might increase levels of uric acid. This might make gout worse in some people.


There is interest in using inosine for a number of purposes, but there isn't enough reliable information to say whether it might be helpful.
