Hydrogen water to reduce fatigue and improve function in ME/CFS

Heart Rate Variability as an Autonomic Marker of Improvement in ME/CFS in a Hydrogen Water Treatment Study

NA · Stony Brook University · NCT07009691

This project will try hydrogen water in adults with ME/CFS to see if it reduces fatigue and improves function and whether heart rate variability can predict who benefits.

What this trial studies

This pilot interventional study enrolls adults with ME/CFS and gives hydrogen water made from an over-the-counter magnesium-based supplement using a 10-day graduated dosing schedule followed by a standard daily dose for 16 weeks. Participants will be monitored for changes in fatigue-related symptoms and physical functioning, and heart rate variability (HRV) will be measured as a candidate biomarker. Investigators plan to identify two outcome subgroups—improvers and non-improvers—and test whether higher baseline HRV predicts clinical improvement. The single-site study at Stony Brook University is intended to generate preliminary data to guide larger trials.

Who should consider this trial

Good fit: Adults who meet the Institute of Medicine criteria for ME/CFS, whose fatigue is not explained by another medical illness, and who do not have psychosis are ideal candidates.

Not a fit: People whose fatigue is due to another diagnosed medical condition or who have active psychosis are unlikely to benefit and would be excluded.

Why it matters

Potential benefit: If successful, hydrogen water could reduce fatigue and increase physical function for some people with ME/CFS.

How similar studies have performed: Prior clinical evidence for hydrogen water in ME/CFS is limited, and using HRV as a predictive biomarker in this condition is largely novel.
