2022 · LeBaron — Electrolyzed-Reduced Water: Review I. Molecular Hydrogen Is the Exclusive Agent Responsible for the Therapeutic Effects
Super-Abstract
With alkaline electrolyzed-reduced water (ERW), it is not „alkaline water“, not „microclusters“, not „free electrons“ that work — but solely the dissolved molecular hydrogen (H₂). This review clears away the pseudo-scientific marketing and traces every documented effect back to H₂. (International Journal of Molecular Sciences, 2022.)
Commentary
This paper by Tyler LeBaron — one of the best-known hydrogen researchers — is a clean-up manifesto. For years, „ionized water“ has been surrounded by sometimes absurd claims: altered „water memory“, microclusters, free electrons, „active hydrogen“, mineral hydrides, or the idea that alkaline water neutralizes „acidic waste“ in the body. It is exactly this pseudo-marketing that long kept serious science from taking ionized water seriously. LeBaron and colleagues go through these claims one by one across in-vitro and in-vivo studies — and refute them. What remains is a clear, chemically sound statement: molecular hydrogen is the only agent that explains both the negative redox potential and the observed therapeutic effects — without any metaphysics. The practical consequence: measure the H₂ concentration of any ionizer, because only that counts — not the pH, not the ORP display alone.
Key quotes
- „it was conclusively demonstrated that H2 was the exclusive agent responsible for both the negative ORP and the observed therapeutic effects of ERW.“ — the core finding: only H₂ acts
- „The associated pseudoscientific marketing has contributed to the reluctance of mainstream science to accept ERW as having biological effects.“ — why ionized water was unfairly dismissed
- „The H2 concentration of ERW should be measured to ensure it is comparable to those used in clinical studies.“ — the practical recommendation: measure H₂, don’t guess from pH/ORP
Our assessment
This is a key reference for the field. It provides the honest, engineering-clean argument that separates serious H₂ use from the esoteric „miracle-machine“ narrative: it is not about „magic alkaline water“ but about a measurable H₂ dose. Mechanistically it puts H₂ concentration at the centre — instead of pH or ORP showmanship. The paper comes from a recognised specialist author (LeBaron, Molecular Hydrogen Institute) and is a systematic synthesis of the primary literature. Limitations, stated honestly: it is a review, not new proof of efficacy — and LeBaron is not impartial in the H₂ field (conflict-of-interest context through his role at the Molecular Hydrogen Institute). Its strength is the mechanistic-chemical debunking of myths, not new clinical endpoints.
Study design
- Type: narrative/critical review (analysis of in-vitro and in-vivo studies) · n: n/a (literature analysis) · H₂ delivery: electrolyzed-reduced (ionized) water as H₂ source
- Result: no pooled effect sizes (narrative synthesis); central conclusion: H₂ is the „exclusive agent“ for the negative ORP and therapeutic effects of ERW; competing explanations (microclusters, free electrons, mineral hydrides, alkaline buffering) are refuted individually
Abstract
Numerous benefits have been attributed to alkaline-electrolyzed-reduced water (ERW). Sometimes these claims are associated with easily debunked concepts. The observed benefits have been conjectured to be due to the intrinsic properties of ERW (e.g., negative oxidation-reduction potential (ORP), alkaline pH, H2 gas), as well enigmatic characteristics (e.g., altered water structure, microclusters, free electrons, active hydrogen, mineral hydrides). The associated pseudoscientific marketing has contributed to the reluctance of mainstream science to accept ERW as having biological effects. Finally, through many in vitro and in vivo studies, each one of these propositions was examined and refuted one-by-one until it was conclusively demonstrated that H2 was the exclusive agent responsible for both the negative ORP and the observed therapeutic effects of ERW. This article briefly apprised the history of ERW and comprehensively reviewed the sequential research demonstrating the importance of H2. We illustrated that the effects of ERW could be readily explained by the known biological effects of H2 and by utilizing conventional chemistry without requiring any metaphysical conjecture (e.g., microclustering, free electrons, etc.) or reliance on implausible notions (e.g., alkaline water neutralizes acidic waste). The H2 concentration of ERW should be measured to ensure it is comparable to those used in clinical studies.
