Hydrogen water is drinking water with added hydrogen gas, proposed to ease oxidative stress and inflammation. The strongest human signals are modest, mainly small cholesterol and metabolic improvements in people with existing metabolic problems, plus limited exercise-recovery and fatigue benefits. Anti-aging claims stay speculative. Safety is high; the evidence base remains young and weak. (Full Review)
| Marker | Target | Why |
|---|---|---|
| LDL Cholesterol | < 100 mg/dL (lower often preferred) | Primary lipid target where hydrogen water shows a small signal |
| Total Cholesterol | ~150–200 mg/dL | Tracks the most reproducible lipid effect |
| Triglycerides | < 90 mg/dL | Inconsistent but possible response marker |
| HbA1c | < 5.4% | Captures average blood sugar; relevant in metabolic users |
| Fasting Glucose | 75–90 mg/dL | Glycemic marker where metabolic trials report change |
| hs-CRP | < 1.0 mg/L | Reflects systemic inflammation, a proposed target |
| ALT | < 25 U/L (varies by sex) | Liver-cell stress marker; relevant for fatty-liver users |
| Fasting Insulin | 2–6 µIU/mL | Early marker of insulin resistance |
Cadence: Baseline before starting, then ~8–12 weeks after starting, and every 6–12 months if use continues.
