In dogs, HRW treatment promoted skin wound healing in dogs, accelerated wound epithelization, reduced inflammatory reaction, stimulated the expression of cytokines related to wound healing, and shortened wound healing time. These preclinical findings add evidence supporting molecular hydrogen's therapeutic potential within the…
Read ArticleThis narrative review examined the available molecular-hydrogen literature. Many studies demonstrate the safety of alkaline-electrolyzed-reduced water (ERW); however, several animal studies have reported significant tissue damage and hyperkalemia…
Read ArticleThe results demonstrated that H₂ treatment reduced the immobility time in the FST ( Figure 3, F = 4.449, p = 0.038). These preclinical findings add evidence supporting…
Read ArticleIn 4 patients with hyperuricemia, following an 8-week period, the High-HRW group exhibited a significant reduction in blood uric acid levels compared to the baseline (488.2 ± 54.1…
Read ArticleIn 2 patients, compared to the control group, participants in HI group maintained greater improvement in the level of HbA1c (-0.94% vs -0.46%), FPG (-22.7 mg/dL vs -11.7…
Read ArticleIn an animal model, after infusion of the H₂-rich glucose solution, H₂ concentration in the portal vein peaked at 0.05 mg/L and remained at more than 0.016 mg/L…
Read ArticleIn 2025 participants with mean body mass index (BMI) ≥ 25 kg/m², HRW significantly reduced total cholesterol (TC) (WMD: − 6.71 mg/dL; 95% CI: − 10.38 to −…
Read ArticleThis meta-analysis examined the available evidence on molecular hydrogen. The results showed a slight decrease in ALT, AST, and ALP levels in the treated group with HRW compared…
Read ArticleJing Chu et al., 2021 Cervical cancer Independent H₂ study in vitro & in vivo Hydrogen gas (67% H₂) 7 days - Treatment with hydrogen promoted apoptosis while…
Read ArticleThis narrative review examined the available molecular-hydrogen literature. H₂ has been found to have selective antioxidant properties against the most dangerous oxidants (hydroxyl radicals and peroxynitrite). The reviewed…
Read ArticleThis meta analysis examined the available molecular-hydrogen literature. The results for the pooled meta-analysis showed a significant reduction in total cholesterol, low-density lipoprotein, and triglycerides after HRW intake…
Read ArticleIn mice, it was found that the collagen content of the treatment group was comparable to that of the control group and the hydrogen water group at 3…
Read ArticleThe authors concluded that administration of hydrogen-rich water improves lung function and alleviates morphological impairments of lung through alleviating inflammation, reducing oxidative stress and lessening mucus hypersecretion in…
Read ArticleIn mice, H₂ decreases H₂O₂ -induced pro-inflammatory cytokine release in human bronchial epithelial cells Under the exposure of 42% H₂, concentration of H₂ in cell culture medium gradually…
Read ArticleIn C57BL/6 mice, levels of inflammatory cytokines (interleukin-1β, interleukin-6, and tumor necrosis factor α) and oxidative stress markers (ie, malondialdehyde) were significantly lower, whereas antioxidant enzyme (total superoxide…
