Explore H2HUBB articles covering molecular hydrogen research, hydrogen water, hydrogen inhalation, dosing, product testing, safety, technology, and practical education for consumers and the hydrogen industry.
In 8 healthy participants, although these data suggest that inhaled hydrogen gas may be well tolerated, future studies need to be powered to further evaluate safety. These findings add human evidence supporting molecular hydrogen's therapeutic potential for stroke recovery.
Read ArticleThis human publication evaluated hydrogen gas in 2014 patients with out-of-hospital cardiac arrest achieved spontaneous return of circulation. This pilot study suggests therapeutic potential, while larger randomized, placebo-controlled…
Read ArticleIn an animal model, no change in the PH or composition of the solution was observed due to hydrogen filling. These preclinical findings add evidence supporting molecular hydrogen's…
Read ArticleIn 2025 participants with placebo or standard water in adults with mean body mass index (BMI) ≥ 25 kg/m2, HRW significantly reduced total cholesterol (TC) (WMD: − 6.71…
Read ArticleThis systematic review examined the available molecular-hydrogen literature. The potential benefits of hydrogen-rich water on various aspects of health, including exercise capacity, physical endurance, liver function, cardiovascular disease,…
Read ArticleIn rats, hydrogen inhalation significantly reduced the number of inflammatory cells in the bronchoalveolar lavage fluid, and the mRNA and protein expression levels of tumor necrosis factor alpha,…
Read ArticleIn a laboratory model, it was confirmed by immunofluorescence that hydrogen treatment could restore the expression of autophagy marker protein LC3 (microtubule-associated protein 1 light chain 3) in…
Read ArticleIn rats, treatment with molecular hydrogen-rich water (HRW) reduced these values to the level of non-irradiated controls. miRNA-1 is known to be involved in cardiac hypertrophy, and was…
Read ArticleIn Both groups received standard treatment plus 4 daily 1-h interventions for 14 consecutive days, although it is generally safe and feasible, its potential effects on myocardial, liver…
Read ArticleIn an animal model, this study used a swine model of mildly hypothermic prolonged circulatory arrest and found that the addition of 2.4% inhaled hydrogen gas to inspiratory…
Read ArticleThis publication examined hydrogen gas using the study design reported by the authoritative source. No study results are reported because this publication is a protocol.
Read ArticleIn 300 participants with correspondingly higher plasma ORP levels compared with control subjects, by investigating this novel approach, the researchers aim to contribute to the growing body of…
Read ArticleIn an animal model, marginal kidney processed by hydrogen gas-containing preservation solution has been engrafted for long-term (longer than 100 days). These preclinical findings add evidence supporting molecular…
Read ArticleThis narrative review examined the available molecular-hydrogen literature. Clinical studies have reported that systemic oxidative stress in patients undergoing dialysis treatment using EHW is suppressed, leading to a…
Read ArticleThis narrative review examined the available molecular-hydrogen literature. Despite compelling preclinical evidence demonstrating efficacy in myocardial injury, neurodegeneration, and systemic inflammation, significant translational barriers remain including delivery optimization,…
