Methods at a glance
Adults with gastroesophageal reflux disease
84 participants: PPI plus H₂-rich water n=44; PPI plus tap water n=40
3 months
Pantoprazole plus 1,500 mL/day electrolyzed reduced water containing dissolved H₂
H₂ dissolved in electrolyzed reduced water — H₂ only, not Brown’s gas.
The complete article does not report a numeric dissolved-H₂ concentration. The device allowed pH 8.10–11.60 and ORP −200 to −800 mV, but these do not substitute for an H₂ concentration.
Not applicable — oral water, not gas inhalation.
No O₂ was co-delivered as part of the intervention.
Pantoprazole plus 1,500 mL/day tap water
Outcomes and reported result
GERD health-related quality of life and oxidative/nitrosative-stress laboratory measures
Symptoms and several redox measures improved in both groups, with some changes reported as greater after electrolyzed water. All participants also received active PPI treatment.
The complete open-access article was checked for intervention preparation, participant flow, outcome tables, funding and conflicts. A numeric H₂ concentration is not reported in the article.
A reported association, difference or mechanism is not automatically a clinical benefit. Null findings, outcome type, study design and precision all matter.
Cautions and applicability
Adjunctive design with active PPI in both groups, questionnaire and laboratory outcomes, and no reported numeric H₂ concentration. The device was supplied by a named provider; authors declared no conflicts and reported public funding.
Adults with GERD receiving pantoprazole under the study protocol; not H₂-water monotherapy.

No single-study GRADE certainty rating is assigned. Certainty is assessed by important outcome across a complete eligible evidence set, not by attaching a final grade to one source.
