From the Guidelines
The current evidence for hydrogen water is limited and inconclusive, and its therapeutic effects remain unproven. While some preliminary research suggests potential benefits such as antioxidant effects, reduced inflammation, and possible improvements in certain health conditions, most studies have been small, short-term, or conducted primarily in animals. Human clinical trials are limited in number and quality, and the proposed mechanism involves hydrogen's ability to penetrate cell membranes and potentially reduce oxidative stress at the cellular level. If you're considering hydrogen water, understand that while it appears generally safe for consumption, its therapeutic effects remain unproven, and it should not replace conventional medical treatments or a balanced diet. Commercial hydrogen water products vary widely in hydrogen concentration, and many lose their hydrogen content quickly after opening 1. Some studies have explored the potential of hydrogen water in conditions like metabolic syndrome, athletic recovery, and neurological disorders, but these findings require larger, more rigorous studies for confirmation. It is essential to consult with a healthcare professional before using hydrogen water for any medical condition, as the current evidence is not sufficient to support its use as a treatment for any disease. In the context of hydration, the evidence suggests that plain water is sufficient for most individuals, and there is no conclusive evidence to support the use of hydrogen water over regular water for hydration purposes 1. Therefore, it is recommended to prioritize conventional medical treatments and a balanced diet over hydrogen water for any health condition, and to consult with a healthcare professional before using hydrogen water.
From the Research
Hydrogen Water Evidence
- The therapeutic potential of hydrogen water has been explored in various studies, with findings suggesting its ability to attenuate chronic inflammation, diminish oxidative stress, and refine tissue functioning 2.
- Hydrogen-rich water (HRW) has been shown to have therapeutic antioxidant properties, mitigating oxidative stress-induced damage through its anti-inflammatory and anti-apoptotic pathways 3.
- The biological effects of HRW include reducing oxidative stress, exerting anti-inflammatory effects, regulating glucose and lipid metabolism, protecting mitochondrial function, and regulating apoptosis 4.
- Molecular hydrogen (H2) has been found to have beneficial effects in diverse animal models and human diseases, including metabolic syndrome, organ injury, and cancer 5.
- A randomized, double-blind, controlled trial found that drinking hydrogen-rich water reduced inflammatory responses and prevented apoptosis of peripheral blood cells in healthy adults 6.
Key Findings
- Hydrogen water has been found to have antioxidant properties, which can neutralize harmful free radicals in the human body 3, 4.
- HRW has been shown to be beneficial in mitigating oxidative stress-induced damage, and may have potential applications in the prevention and treatment of various diseases 3, 5.
- The mechanisms behind the potential benefits of hydrogen-rich water are not yet fully understood, and further research is needed to substantiate the findings 3, 4.
- Studies have found that hydrogen water may have anti-inflammatory effects, and may be useful in reducing inflammatory responses in healthy adults 6.
Potential Applications
- Hydrogen water may have potential applications in the prevention and treatment of various diseases, including cardiovascular disease, mental health, COVID-19, and oxidative stress-related disorders 3, 5.
- HRW may be useful as an adjunctive therapeutic approach, and may have potential benefits for exercise capacity, physical endurance, liver function, and anti-aging research 3, 4.
- Further research is needed to fully explore the potential benefits and mechanisms of hydrogen-rich water, and to determine its safety and efficacy in various clinical applications 2, 3, 4.
