The claimWhat Gary actually said
Brecka has promoted hydrogen-rich water as a daily habit, describing it in the terms quoted above while pointing to a pilot study in older adults that reported telomere lengthening. McGill University's Office for Science and Society reviewed the claim in November 2025 and noted that the pilot trial was funded in part by a company selling hydrogen-rich water. The underlying idea is that dissolved molecular hydrogen acts as a selective antioxidant.

- Zhou K, Frontiers in Nutrition, 2024, meta-analysis of 27 publications and 597 participants found hydrogen improved lower-limb explosive power and fatigue but not aerobic endurance or strength.
- Zhou K, Frontiers in Nutrition, 2023, systematic review and meta-analysis of molecular hydrogen supplementation on fatigue and aerobic capacity in healthy adults.
- Zanini D, Experimental Gerontology, 2021, six-month randomized controlled pilot trial in 40 adults aged 70 and over reported preserved telomere length with hydrogen-rich water, with most biomarkers unchanged.
Why it mattersWhy this matters for longevity
Hydrogen water devices and tablets are sold at a steep markup on the strength of pilot-stage evidence
Telomere length is a biomarker, not an outcome, and changes in it have never been shown to translate into longer life in humans
A study funded in part by a seller of the product being tested needs independent replication before it carries weight
The evidenceWhat the science says
A 2024 systematic review and meta-analysis covering 27 publications and 597 participants found that molecular hydrogen supplementation improved lower-limb explosive power, reduced rating of perceived exertion, and helped blood lactate clearance, while showing trivial and non-significant effects on aerobic endurance, anaerobic endurance, and muscular strength. A companion review reported similar small effects on fatigue and aerobic capacity. The authors called for more rigorous designs before drawing conclusions.
The evidence does not support hydrogen water as a longevity or anti-aging intervention. The single trial behind that claim randomized 40 adults over 70 to 0.5 litres a day for six months and reported preserved telomere length and better chair-stand performance, with most other biomarkers unchanged. It was explicitly a pilot, it was small, and per McGill's review it was funded in part by a company that sells hydrogen-rich water. There are no trials of hard outcomes such as disease incidence or mortality, and tablet-based delivery raises separate questions about whether a meaningful dose reaches the body at all.
TakeawayThe honest takeaway
The practical lesson
If you enjoy it and it is affordable, it is unlikely to hurt you, but treat it as an experiment rather than a longevity strategy.

SupplementsThe supplement angle: Antioxidant supplements generally
Support a habit, do not replace one
The wider antioxidant supplement literature is a caution rather than a promise, since several high-dose antioxidants have failed to improve outcomes and a few have blunted training adaptations. Hydrogen water sits at an early stage of testing and should be judged on future replication, not on current marketing.
Supplements can support good habits. They do not replace sleep, movement, nutrition, or medical care. Talk with your healthcare provider before starting anything new.
