Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1This trial looked at how molecular hydrogen affects 400-meter fin-swimming performance and oxidative stress in elite swimmers — could hydrogen supplementation be relevant to my own training situation, or is it really only meaningful for national-level competitive athletes?
2Since this study has already been completed, would my doctor be able to help me find or access any published results showing whether hydrogen administration actually reduced muscle fatigue or improved swim times?
3The trial measured oxidative stress as part of the body's response to exercise — can my doctor explain what oxidative stress means for muscle recovery, and whether there are already proven strategies I should consider before exploring hydrogen supplementation?
4Molecular hydrogen is the intervention here, but I'm not sure how it's typically administered — would my doctor know whether the delivery method used in this trial (like hydrogen-rich water or gas inhalation) carries any safety considerations I should understand?
5Because this trial was categorized as Phase NA, meaning it wasn't a standard drug-approval phase study, what does that tell us about how much we can trust the findings, and would my doctor consider the evidence strong enough to inform any real decisions about my training or recovery?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
