Product Details
Inside every HYDROGENYX device, special technology transforms ordinary water into hydrogen-rich water.
At the heart of the system is the HYDROGENYX hydrogen generator. It uses two platinum-coated titanium plates, separated by a thin proton exchange membrane (SPE/PEM). These laboratory-grade materials were rigorously selected for their strength, purity, and safety.
The proton exchange membrane was initially developed for NASA. Today, this same technology is used in hydrogen cars and the most advanced industrial machinery. It allows pure hydrogen gas to be dissolved directly into your water, while releasing residual oxygen into the air.
The carefully studied shape of our plates ensures perfectly uniform electrical current distribution, without overheating or risk of deterioration. This allows the HYDROGENYX generator to produce hydrogen much faster and more efficiently.
Each component is designed from laboratory-grade materials and built to last so you can always count on pure, high-quality hydrogenated water.
Concentration & DPD Verification
The announced concentration—up to 9,000 PPB (9.0 mg/L) of dissolved hydrogen at the end of the cycle—comes from the technical data of our partner manufacturer.
You don't have to take our word for it: the concentration can be verified with DPD reagent, the reference colorimetric method for measuring dissolved hydrogen. A kit costs about €20 online and the protocol takes two minutes—it is detailed on our Science page.
Hydrogen gas is also authorized as a food additive in the European Union (E 949). The materials in contact with water—BPA-free clear reservoir, medical-grade soft silicone, titanium cell and membrane—are selected for use with drinking water.
Shipping & Returns
Standard delivery free in France and Europe: 6 to 10 business days, tracking included. Need your device faster? Express: 4 to 8 business days, €10.99.
Not completely convinced? 60-day money-back guarantee: write to contact@hydrogenyx.fr, return label provided.
5-Year Warranty
5-year warranty on the SPE/PEM cell: if it no longer produces properly hydrogen-enriched water (checked with DPD reagent), free replacement. Battery guaranteed for 2 years. 60-day money-back guarantee, no questions asked.
Customer service in France: contact@hydrogenyx.fr — response within 24 business hours.

Hydrogen Water: What Research Is Studying
Designed for recovery
Studied for recovery: one study (Aoki 2012, footballers) observed a decrease in blood lactate during exercise — a study finding, not an individual promise.
Microbiome: an area of study
The role of H₂ in the gut microbial ecosystem is explored by research.
Designed for focus
Mental clarity is one of the areas explored by research on molecular hydrogen.
Designed for Sleep
Sleep is one of the areas studied by research — study results, never a promise.

How HYDROGENYX Flask Transforms Your Water
-
Step 1
Pour in the water. Tap, fountain, spring. The cell takes care of the rest.
-
Step 2
Start the cycle. The 4th generation SPE/PEM Pt-Ir cell activates: 5 min (4.5 ppm) or 10 min (9 ppm).
-
Step 3
Drink up to 9,000 PPB H₂. Manufacturer's data — verifiable with DPD reagent. Drink within 20-30 minutes after the cycle.
