The Beneficial Action of Molecular Hydrogen
Since 2007 there have been around 2,000 research papers demonstrating that Molecular Hydrogen has both antioxidant and anti-inflammatory effects throughout a broad range of biological applications and species.
Molecular Hydrogen acts as a powerful antioxidant in biological systems both directly and indirectly. Directly by scavenging some Reactive Oxygen Species and indirectly by boosting our natural antioxidant system. Hydrogen alone consists only of one electron and one proton, but it is in its molecular form H2 that we see the amazing biological significance. Molecular Hydrogen is the smallest molecule in our universe and thus can diffuse passively throughout a body, reaching every part of every cell where larger antioxidants cannot. But that is only the beginning of the story. Research in humans and other animals that:
- Molecular Hydrogen manages oxidative stress1,2,2–17.
- Molecular Hydrogen acts as an anti-inflammatory3,18–30,30–32.
- Molecular Hydrogen decreases proinflammatory cytokines e.g.22,33,34.
- Molecular Hydrogen modulates the action of the NF-kB transcription factor e.g.34–37.
- Molecular Hydrogen can help combat cancers and help alleviate the undesirable side effects of common therapies 38–61
- Molecular Hydrogen supplementation induces reactivation of exhausted immune cells 38,39,62.
- Molecular Hydrogen can mitigate Diabetes type I and II 63–70
- Molecular Hydrogen attenuate the damage caused by ischemia and reperfusion 1,2,5,8,11,15,36,71–119
- Molecular Hydrogen shows positive action in models of mental disorder 120–122 as well as human 123 for review of the potential see 124.



Research related to food production has shown that:
- Molecular Hydrogen-rich water improves the yield of barley and wheat by up to 16% 125 to 31% (CSIRO studies).
- Molecular Hydrogen-rich water used on cherry tomatoes suppresses the need for fertiliser while improving the taste and the yield by 9.1% a yield superior to the one achieved with conventional compound fertiliser 126.
- Molecular Hydrogen-rich water used on cherry tomatoes while using fertiliser improves taste and yield by 26% 126.
- Molecular Hydrogen supplementation alleviate abiotic stress in plants 127–131
- Molecular Hydrogen supplementation improves post-harvest freshness 132–134
- Molecular hydrogen supplementation improves soil microbiota 125,135,136.
- For review see 137,138
It is likely that all these very diverse positive effects stem from an increased mitochondrial ATP production demonstrated by Gvozdjáková et al 139 and the suppression of superoxide production at complex I of the mitochondria 140. It is important to remember here that ATP is the main energy currency in biology and that it promotes protein folding while preventing the aggregation of misfolded protein 141,142.
We believe that the biological relevance of Molecular Hydrogen represents the single most important technology on the planet today.
