Can a simple hydrogen drink ease chronic fatigue?
NCT ID NCT07753122
First seen Aug 07, 2026 · Last updated Aug 07, 2026
Summary
This trial tests whether drinking hydrogen-rich water for 16 weeks can reduce fatigue and improve physical functioning in people with ME/CFS (chronic fatigue syndrome). Half of the 80 participants will receive the active supplement, while the other half gets a placebo. The study also checks if a heart-rate variability measure can predict who improves, which could help personalize future treatments.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Molecular hydrogen produced by a metallic magnesium tablet dissolved in water, taken three times daily for 16 weeks.
- What this could lead to
- If effective, hydrogen water could offer a simple, over-the-counter option to reduce fatigue and improve daily functioning in ME/CFS.
- What could go wrong
- This is a small, early-stage trial, and the supplement may prove no better than placebo. The biomarker prediction is exploratory and not yet confirmed.
