Science

What the literature says.

Molecular hydrogen (H₂) has been studied since 2007 — the seminal publication by Ohsawa et al. in Nature Medicine.

H₂ acts as a selective antioxidant: it targets the hydroxyl radical (OH·) and peroxynitrite (ONOO-), without neutralizing species useful for cell signaling.

Since then, several hundred studies have been published in peer-reviewed journals: sport and recovery, oxidative stress, metabolism, fatigue, and mood.

7 reference studies are summarized on the studies page — cited as research, never as proof of effect.

Research, year by year.

  1. 2007 · Ohsawa et al.

    Nature Medicine. Landmark publication: H₂ identified as a selective antioxidant targeting OH· and ONOO- (preclinical models).

  2. 2008 · Kajiyama et al.

    Nutrition Research. Controlled trial in adults with impaired glucose metabolism: decrease in oxidative stress markers observed vs. placebo.

  3. 2012 · Aoki et al.

    Medical Gas Research. Elite footballers, n=10, crossover study vs placebo: decrease in blood lactate observed during exercise.

  4. 2017 · Mizuno et al.

    Medical Gas Research. Pilot study in healthy adults: fatigue and mood scores followed over 4 weeks.

  5. Today

    Hundreds of PubMed-indexed publications, literature reviews (LeBaron 2019, Ostojic). An active field of research — not proof of effect.

Scientific Honesty

"Hydrogen is not a drug. No curative effect has been demonstrated. But several hundred publications converge on a modulating effect on oxidative stress.

We summarize this literature — without distorting it."
