Hydrogen water bottle benefits: Hype, risks, and what the science actually says

Hydrogen water bottles dissolve extra molecular hydrogen (H₂) into water, and early small human studies suggest modest reductions in oxidative-stress markers and post-exercise fatigue via a “selective antioxidant” effect. These results are not the dramatic recovery, focus, or anti-aging outcomes often marketed. Here’s how these devices generate H₂, what the research and real-world risks show, ...
