Our take on the H2next Hydrogen Water Bottle

The H2next is a rechargeable portable bottle that runs electrolysis on the water inside it to add dissolved hydrogen gas, which the maker markets as an antioxidant boost. It is a single-wall bottle with a built-in generator base, so it is heavier and more complex than a plain stainless or plastic bottle. It suits people curious about hydrogen water who want to make it themselves instead of buying it bottled. Against ordinary insulated bottles it adds a feature most rivals don't have, but it does not keep drinks hot or cold and the health claims are not backed by strong evidence.

Questions and answers

Does it actually make hydrogen water?
Yes. It uses electrolysis on the water in the bottle to produce dissolved hydrogen gas. Concentration is highest right after a cycle and drops over time, so drink it soon after generating.
Does it keep water cold?
No. It is not an insulated bottle, so it does not hold temperature like a vacuum flask. It works as a regular bottle plus a generator base.
How is it powered?
It has a built-in rechargeable battery charged over USB. A charge covers several generation cycles, and you recharge it rather than replacing cartridges.
Can I put juice or soda in it?
Use plain drinking water. Sugary or acidic drinks can foul the electrodes and affect the electrolysis. Rinse and dry the base after use.
Is the hydrogen water proven to help health?
Evidence is limited and mostly small studies. Hydrogen water is marketed for antioxidant effects, but it is not a treatment for any condition. Treat the claims with caution.
Why does it carry a Proposition 65 warning?
California requires the warning when a product may expose users to listed chemicals. It does not by itself mean the bottle is unsafe, but read the label if you are concerned.
Where is the H2next Hydrogen Water Bottle cheapest?
At Walmart, for $31.68, as of our latest check.
What do buyers say about the H2next Hydrogen Water Bottle?
