Can Hydrogen Water Lower Uric Acid? What an 8-Week Trial Found

High uric acid levels are the underlying driver of gout, and they're linked to broader metabolic and kidney health too — which makes this a meaningful outcome to test, not just a lab-value curiosity.

What the research looked at

Published in Heliyon in 2024, this randomized, placebo-controlled trial enrolled 100 adults with hyperuricemia (elevated blood uric acid). Participants were assigned to one of three groups for eight weeks: a placebo group drinking ordinary water, a low-dose hydrogen-rich water group, or a high-dose hydrogen-rich water group. Blood uric acid was measured at baseline, four weeks, and eight weeks.

What they found

After eight weeks, the high-dose hydrogen-rich water group showed a statistically significant drop in blood uric acid, from an average of 488.2 to 446.8 µmol/L — a reduction of about 41 µmol/L. The lower-dose group's results were less pronounced.

What this means in practice

This is a reasonably sized, well-controlled trial with a clear dose-response pattern (more hydrogen, bigger effect), which strengthens confidence in the result. It's a single trial, though, so it would benefit from independent replication before being treated as settled, and it doesn't tell us whether the uric acid reduction translates into fewer gout flares over the long term. For people managing elevated uric acid, this is a promising, low-risk data point to discuss with a doctor — not a replacement for standard gout management.
