Hydrogen-Rich Water

Estimated longevity benefit: +0.7 years. Evidence score: 70/100.

Hydrogen-rich water (HRW) contains dissolved molecular hydrogen (H₂) gas which acts as a selective antioxidant by targeting the most damaging reactive oxygen species. This selective reduction of oxidative stress has shown potential in preliminary human trials to preserve telomere length and reduce systemic inflammation, markers of biological age.
