Meet Prof. Sergej Ostojic
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:
- Maximal running speed (vmax)
- Anaerobic threshold performance (vANT)
- Hydration and physiological biomarkers
- Self-reported wellbeing and physical readiness
These findings contribute to the growing scientific interest in molecular hydrogen and its potential role in advanced hydration and human physiology.
The Community of High Performers
Trusted by athletes, innovators, and performance-driven individuals who prioritise precision hydration.
“I drink before every workout”
“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!”
“sleep scores were better”
“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.”
“The results speak for themselves!”
“HtoEau® had a positive effect on my chronic fatigue, hydration and recovery from exercise. As I work in professional sport, I would also recommend this water to any competitive athlete.”

Frequently Asked Questions
Everything you need to know about hydrogen-infused hydration and the science behind HtoEAU.
What does it taste like?
HtoEAU® tastes like exceptionally pure, clean water, with no aftertaste. Molecular hydrogen is colourless, odourless, and tasteless, so the purity of naturally alkaline glacial water is all that you will experience.

How many cans should I drink per day?
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.
