Abstract

fetched live from OpenAlex

Hydrogen-rich water (HRW) has emerged as a promising therapeutic intervention due to its antioxidant and anti-inflammatory properties. Recent studies suggest that the ingestion of HRW may alter gut microbiota composition, potentially influencing various health outcomes such as metabolic, inflammatory, and neurological conditions. However, no comprehensive synthesis of the evidence exists. This systematic review aims to evaluate and synthesize the available literature on the effects of HRW on gut microbiota composition and its associated health outcomes. We conducted a systematic search of electronic databases, including PubMed, Scopus, Google Scholar, Cochrane Library, ProQuest, Web of Science, and Gray Literature. We included studies of human or animal populations exposed to HRW, focusing on randomized controlled trials, cohort studies, case-control studies, and relevant in vivo / in vitro studies. Two independent reviewers carried out data extraction, and they assessed the risk of bias using appropriate tools for each study design. We will synthesize the findings narratively to identify the impact of HRW on gut microbiota diversity and health-related outcomes such as metabolic, inflammatory, and immune system markers. This review aims to provide a comprehensive understanding of HRW's effects on gut microbiota and its broader health implications, highlighting current evidence gaps and suggesting directions for future research.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
