Hydrogen water (molecular hydrogen)

Tier 2 — promising · Antioxidant · Anti-inflammatory · Trending

Water infused with dissolved molecular hydrogen (H2) gas. Over 50 small clinical trials show modest anti-inflammatory and antioxidant effects. A 2024 meta-analysis found hydrogen-rich water significantly reduced inflammatory markers (IL-6, CRP) in metabolic syndrome. Extremely safe — H2 is inert and non-toxic. Main limitation is that dissolved H2 escapes rapidly once the container is opened. Evidence is preliminary.

Dose: 500 mL–1.5 L hydrogen-rich water daily (0.5–1.6 ppm dissolved H2); drink immediately after opening
