Ohsawa et al. 2007
A landmark mechanism paper often cited in molecular hydrogen discussions. It is useful background, not a product claim.
Research library
Molecular hydrogen research: read the studies, not the hype.
Molecular hydrogen has a growing scientific literature. We summarize it carefully: what was studied, what was found, and what cannot be claimed from it.
Clinical reviews
Reviews summarize human research, administration routes, and safety discussion across the field.
Inhalation studies
Some studies use inhalation protocols. Their findings should not be transferred directly to this device.
Exercise literature
Reviews discuss antioxidant-capacity markers with mixed and still-developing evidence.
A note that applies to everything above: this research describes molecular hydrogen as a subject of scientific study. It is not a claim about the I regenerate device or any specific outcome for an individual user.
Reading list
Research belongs in context.
We treat studies as education about molecular hydrogen as a field, not as a promise about how any individual will feel.
Publications
Selected reading on molecular hydrogen.
The links go to PubMed. These studies describe molecular hydrogen as a field of research; they are not claims about Lita Air or about how any individual will experience the device. The evidence is promising but not yet sufficient for general clinical recommendations.
Hydrogen acts as a therapeutic antioxidant by selectively reducing cytotoxic oxygen radicals
The foundational study showing hydrogen selectively reduces the most cytotoxic oxygen radical without quenching radicals that have a physiological role.
