From Molecular Hydrogen to Next-Level Hydration

What happens when advanced infusion technology meets pure hydration?

The science-driven approach
to advanced hydration and performance

Hydrogen

The Smallest Molecule. A New Frontier in Hydration.

Molecular hydrogen is increasingly studied for its potential role in human physiology. Its small size allows it to dissolve into water when infused using precision-controlled technology.

  • Evaluated in controlled human research
  • Precision infusion
  • Clean, stimulant-free hydration

By infusing pure molecular hydrogen into water, we give your cells immediate access to this high-performance fuel — no pills, no guesswork, just hydration that works.

Deuterium

Refined Through Precision Distillation.

Deuterium is a naturally occurring form of hydrogen present in all water. HtoEAU® Deuterium-Depleted Water undergoes specialised distillation to reduce deuterium concentration and deliver refined hydration.

  • Precision-distilled to reduce deuterium levels
  • Produced under controlled quality standards
  • Clean, additive-free hydration
  • Exceptional purity and consistency

Find out more about the science

We Started With Physics. Not Marketing.

Hydrogen water is easy to talk about. It's much harder to produce properly.

Hydrogen escapes easily. It destabilises quickly. It demands precision. If you're not engineering for stability, you're producing a story.

We Engineer Hydrogen. We Do Not Simply Add It.

Our process is designed to optimise dissolved hydrogen concentration, protect hydrogen integrity, and preserve stability from infusion to sealing. Because hydrogen performance isn't a label claim. It's an experienced reality.

A New Standard

Engineered. Measured. Performance-driven. Not just hydration. Hydrogen precision.

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.

“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!”

Daniel Ventura WBFF Pro Fitness Model, Actor, Advanced Personal Trainer

“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.”

Endurance Cyclist, Age 62 Garmin VENU X1 User

“The results speak for themselves!”

“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.”

Heather Pearson MSc Sports Therapist & Strength Coach

"Hydration that goes beyond the surface."

“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.

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. Molecular hydrogen is colourless, odourless, and tasteless, so there are no added flavours or aftertaste.
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.
Is there real science behind hydrogen-infused water?

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.
How is HtoEAU® different from regular water?

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.
Who is HtoEAU® designed for?

HtoEAU® is developed for athletes, high performers, and individuals who prioritise advanced hydration as part of their daily performance and wellbeing routines.
