Infused to a minimum therapeutic level of 5 mg/L dissolved hydrogen at the point of filling, ensuring reliable hydrogen concentration in every can.
Pressurised filling and controlled headspace help preserve dissolved hydrogen, maintaining stability from production to consumption.
Hydrogen’s extremely small molecular size allows it to dissolve easily in water and disperse efficiently throughout the body.
No sugar, stimulants, or additives. Just purified water and molecular hydrogen.
Minimum 5 mg/L dissolved hydrogen at filling.
Three-stage filtered and UV-treated water.
Recyclable aluminium cans designed to preserve product quality.
Zero sugar. Zero calories. No additives.
HtoEAU® Hydrogen-Infused Water was evaluated in a 4-week randomized, double-blind, placebo-controlled study led by Professor Sergej Ostojic (MD, PhD), a leading researcher in human physiology and exercise science.
The study examined hydrogen-infused water in trained collegiate athletes under controlled conditions, measuring key physiological and wellbeing indicators, including:
These findings contribute to the growing scientific interest in molecular hydrogen and its potential role in advanced hydration and human physiology.

“I’ve reached a level of physical fitness where I can ascertain if any supplement I take can give me an extra edge. HtoEau is something I drink before every workout now, and no matter how tired I may feel before training I can now push through with seemingly an extra gear and end up having a great session. If you’re serious about fitness and recovery it’s a must have pre-workout!”
“Last summer, I kept track of three weeks of training and recovery, during which I consumed one can of HtoEAU Hydrogen Water every morning and evening. What helped me the most and also surprised me was that my sleep scores were better than usual. I have noticed that the right nutrition and the use of HtoEAU Hydrogen Water have contributed to improving my values, so even at my more advanced age, it is possible to improve.”
“HtoEau® DDW water had a positive effect on my chronic fatigue, hydration and recovery from exercise. Hence, I would highly recommend this water to anyone suffering with a chronic illness. As I work in professional sport, I would also recommend this water to any competitive athlete.”
“I started drinking DDW alongside my psoriasis treatment, aiming for around 2L a day. It was easy to drink and tasted great, so helped me stay consistent. Within weeks, my skin looked noticeably better, and I felt an improvement in my overall well-being. I strongly feel that the Deuterium Depleted Water has supported my results, especially in terms of hydration, skin appearance, and recovery.

Everything you need to know about hydrogen-infused hydration and the science behind HtoEAU.
HtoEAU® tastes like exceptionally pure, clean water. Molecular hydrogen is colourless, odourless, and tasteless, so there are no added flavours or aftertaste.
Individual hydration needs vary depending on activity level, environment, and personal routine.
In the clinical study, participants consumed 660 mL daily. Many users incorporate 1–2 cans per day as part of their regular hydration and performance routines, but it is perfectly safe to drink more.
Yes. Molecular hydrogen has been the subject of growing scientific research exploring its potential role in human physiology and performance.
HtoEAU® Hydrogen-Infused Water was evaluated in a 4-week randomized, double-blind, placebo-controlled study involving trained collegiate athletes. The study examined performance, physiological, and wellbeing indicators under controlled conditions.
This research contributes to the broader scientific interest in hydrogen-infused hydration and its potential applications in performance-focused environments.
While research is ongoing, hydrogen-infused water continues to be studied as part of the evolving field of advance hydration science.
HtoEAU® is infused with molecular hydrogen using a precision-controlled system designed to maximise hydrogen stability and retention.
Molecular hydrogen has been widely studied for its potential interaction with oxidative stress and inflammatory pathways, contributing to growing scientific interest in its role within human physiology.
HtoEAU® is developed for athletes, high performers, and individuals who prioritise advanced hydration as part of their daily performance and wellbeing routines.
It is especially suited to those seeking clean, stimulant-free hydration supported by emerging scientific research.
