Molecular Hydrogen Research
In just 13 years of molecular hydrogen research, there have been over 2,000 published scientific articles on the health benefits of various methods of hydrogen consumption. Publications on human trials using hydrogen as a therapeutic agent are over 120. Hydrogen therapy has been shown to benefit every organ in the mammalian body in over 170 trials.
As of our last update on molecular hydrogen research, there are 128 publications on hydrogen therapy in humans. The majority, 68, cover drinking hydrogen water. Hydrogen inhalation is a distant second with 25 publications, hydrogen-rich saline is third with 11 publications, and topical hydrogen therapy has ten publications, eight of them on hydrogen water bathing. Finally, three publications cover a product used to create hydrogen gas inside the body, two by hydrogen tablets, and one by the drug acarbose, and several additional methods. This totals 130 administration methods because in two of the publications more than one delivery method of hydrogen therapy was used.
Of the 124 human trials, four did not find a benefit. But 120 did, which is a 97% success rate of using hydrogen therapy. Of note, none of the molecular hydrogen research trials that have found a benefit are phase III–type multicenter trials, although many are randomized, double-blind, placebo-controlled phase I– and phase II–type trials. As such, no firm conclusions can be made on the efficacy of hydrogen therapy for any of these indications. Also of note, precise dosing and delivery method, as well as the timing of consumption, are not yet established for any indication, and the literature varies widely in this regard.
This molecular hydrogen research database compiles the ongoing human research on hydrogen therapy for researchers and consumers alike and is not intended to be used to diagnose, treat, or cure any disease.

There are currently 15 publications on human trials for hydrogen therapy and various metabolic outcomes. Hydrogen water is the most common mode of delivery, with hydrogen water research accounting for twelve of the 15 publications. Two publications discuss ways to produce molecular hydrogen within the body, and one discusses hydrogen inhalation.

Athletic Performance, Recovery, and Athlete Health
There are currently 36 publications on hydrogen therapy in humans, exploring various outcomes related to athletic performance, recovery, athlete health, and recovery from sports-induced injuries. The overwhelming majority of these studies is again using hydrogen water, with 26 of the publications on consuming hydrogen water orally (although one did not find a benefit), four studies using topical hydrogen water or hydrogen gel, four studies using hydrogen inhalation, one study using hydrogen tablets intended to produce hydrogen gas within the body, one study with H2-rich calcium powder and one study using H2-infused beverage. This total adds to 37, not 36, as one of the studies used a two-pronged intervention of both the oral hydrogen tablets as well as the topical hydrogen-rich gel.

Brain Recovery From Acute Injury, Neurological Conditions, and Brain Health
There are currently 17 publications exploring various neurological outcomes from hydrogen therapy in humans. Regarding hydrogen therapy and the brain, the methods are more spread out, with seven of the 16 studies involving hydrogen water (although one did not find a benefit), six of the studies using hydrogen inhalation (although two did not find a benefit), two of the studies using hydrogen-rich saline, one using intravenous hydrogen therapy and one using H2-infused, nitric oxide-producing functional beverage.

****This one needs some context. There were massive failures in this trial, namely there were mix ups in the placebo control group where they were intermittently given high doses of hydrogen in the water. Both placebo and control saw significant improvements over expectations and analysis against similar trials, but no benefit against each other. Both were receiving high dose hydrogen. One daily, the other perhaps every other day, and daily receiving at least 0.16mg/L cited in paper. The exact routine is unknown. There is currently underway a 52-week, 70-participant trial on Parkinson’s Disease in the USA. The registration can be found here
Regardless, we cannot state that H2 is beneficial for PD. We simply do not know. I cannot overstate this enough. We do not know, and it is unethical for marketers to push H2 for patients with PD.

Electrically Reduced Water and Magnesium-Based Ingestible Interventions for “-ORP”
“Ionized water” or “electrolyzed water” uses electrolysis and dissolves H2 gas in varying amounts into the water. This is what gives it the negative “ORP.” Likewise, elemental magnesium-based products designed for a “negative ORP” were creating said “negative ORP” by generating molecular hydrogen. That said, exact dosages and concentrations are not known from these studies, so we have segmented them off from the “molecular hydrogen research.”

Magnesium Implants
Researchers in the field of biodegradable magnesium implants are certainly aware that the degradation of the magnesium produces molecular hydrogen. They even use hydrogen gas creation to map the degradation of the implants.[i] However, they seem unaware of any potential therapeutic benefits of said molecular hydrogen, and as such, none of these studies mention anything relevant in order to ascertain dosages and benefits of the hydrogen gas, such as mass of magnesium needed to extrapolate hydrogen creation or rate of reaction. These studies should be tracked, nonetheless, in the event they may be included into the molecular hydrogen therapy story in the future.
