The HYDROGENYX promise
Pas une bouteille.
Une mesure.
Most hydrogen water bottles advertise figures that cannot be verified. We took the opposite approach.
Hydrogen content is not a promise: it is verified with the DPD reagent. A few drops, the water changes color, the level is read.
Platinum-Iridium SPE/PEM cell, touchscreen, wireless charging base included. An object designed to last.
Online DPD kit (~€20): check the concentration at home, whenever you want.
5-year cell warranty: free replacement if the water is no longer properly enriched (DPD control).
Benefits
Why hydrogen water
Selective antioxidant (under study)
Molecular hydrogen is being studied as a "selective" antioxidant. Research is progressing – we remain factual, without making any health promises.
Flavorless, calorie-free
The taste of pure water: zero flavor, zero calories, zero sugar. Just water enriched with H₂, for daily consumption.
A Lasting Ritual
Refillable water bottle from a French brand, 5-year warranty on the cell. A simple daily gesture, not a consumable item.
Molecular hydrogen has been studied since 2007 (Ohsawa, Aoki, Ostojic, LeBaron). It's a field of research — never proof of effect.
First Use
Your ritual, in three steps
-
Fill in
400 ml of still water, preferably low in mineral content. The Flask fits everywhere.
-
Start the Cycle
A touch on the screen: the SPE/PEM Platinum-Iridium cell enriches the water with molecular hydrogen.
-
Drink — or Check
Consume immediately, or check the concentration with a DPD reagent (online kit ~€20).

Questions fréquentes
Hydrogenated water, what is it?
Pure water enriched with molecular hydrogen (H₂), a gas. Tastes the same as normal water, with a verifiable concentration using the DPD reagent: a few drops, the water changes color, and the level can be read. Science in detail.
Is it safe?
Hydrogenated water is drunk like regular water. We do not claim any therapeutic effects, and our bottle does not replace any treatment — for any health questions, please consult a professional.
Which product should I choose?
- Flask — nomadic flask, €239 instead of €299, 4x Klarna interest-free
- Inhalers (Station, Air, Pro) — gaseous hydrogen
