Inosine: What it is and why people try it

Inosine is a naturally occurring molecule your body makes when it breaks down RNA and other nucleotides. People take it as a supplement for different reasons: some hope it helps brain health, others use it for athletic recovery, and researchers have tested it to raise uric acid in Parkinson’s studies. That doesn’t mean it’s a cure — it’s a tool with clear pros and cons.

What inosine does

Inosine can raise serum uric acid because it breaks down into urate in the body. Higher urate levels may have antioxidant effects, which is why some Parkinson’s trials (for example, the SURE-PD studies) tested inosine to see if it slowed disease progression. Results showed inosine reliably increased urate, but benefit for slowing Parkinson’s symptoms isn’t proven.

As a supplement, people report better energy or recovery, but strong clinical proof for athletic performance is limited. Don’t confuse plain inosine with prescription drugs that contain inosine-related compounds (like inosine pranobex), which are different and used in some countries as antivirals or immune modulators.

Safety, dosing, and practical tips

Common side effects include upset stomach and increased uric acid. The real risks come from elevated uric acid: gout flares and kidney stones. If you have a history of gout, kidney disease, or high uric acid, avoid inosine unless your doctor says otherwise.

Doses used in studies vary. Supplement users often take 500–2,000 mg per day in divided doses, but clinical trials that raised urate used carefully monitored regimens. Don’t copy someone else’s dose — talk to a clinician first.

Before trying inosine, get a baseline serum uric acid test. If you start it, check uric acid again within a few weeks and periodically after that. Drink enough water to lower stone risk. Stop and contact your doctor if you get sudden joint pain, sharp flank pain, or persistent nausea.

Watch for drug interactions. If you take medications that affect uric acid or kidney function, discuss inosine with your prescriber. Also avoid combining it with other supplements that raise uric acid without medical advice.

Bottom line: inosine has interesting biological effects and was useful in some research settings, but it’s not risk-free. If you’re curious, get medical guidance, test your uric acid, start at a low dose if cleared by your doctor, and monitor for side effects.
