H2HUBB TAKEAWAY

NHE water diminished hydroxyl radicals as demonstrated by ESR in a cell-free system. These findings come from a laboratory model and suggest molecular hydrogen's biological potential. Further research is needed to determine clinical relevance. This cellular study evaluated neutral-pH hydrogen-enriched electrolyzed water. Oxidant and peroxide-related terminology describes the experimental outcome rather than the identity of the intervention.

What the Researchers Tested

The properties and effects of neutral pH hydrogen-enriched electrolyzed water (NHE water) on tumor cells were examined.

Laboratory Model

The properties and effects of neutral pH hydrogen-enriched electrolyzed water (NHE water) on tumor cells were examined.

How Molecular Hydrogen Was Used

The properties and effects of neutral pH hydrogen-enriched electrolyzed water (NHE water) on tumor cells were examined. Intracellular oxidants such as hydroperoxides and hydrogen peroxides were scavenged in HSC-4 or HT-1080 cells by NHE water. In the human oral cavity, a dissolved hydrogen concentrations (DH) of NHE water was drastically declined from 1.1 to 0.5 ppm, but settled to 0.3-0.4 ppm until 180 s, upon static holding without gargling.
