What is hydrogen?

Hydrogen, or H1 as the scientists amongst us refer to it, is a gas – in fact it is the lightest element in the periodic table. In nature, hydrogen atoms tend to bond with other atoms. For example, when two hydrogen atoms bond, they form molecular hydrogen, or H2. When H2 bonds with a single oxygen atom, this becomes water – commonly known as H2O.

So, what exactly is hydrogen water?

Well, obviously hydrogen is present in all water, but HtoEau® contains pure molecular hydrogen. It is infused into the water under pressure and infiltrates the water molecules.

Why do you add molecular hydrogen to water, anyway?

Because one of the most accessible and easy ways to consume molecular hydrogen is by drinking hydrogen-enriched water!

Due to current levels of stress, pollution, poor diet and certain lifestyles, our bodies gain free-radicals, excess levels of which contribute to the breakdown of our DNA, ribonucleic acid and proteins, leading to cell damage and disease. Because hydrogen molecules are so small, they can easily and quickly be diffused into the bloodstream, and have an antioxidant effect, amongst other potential benefits. By penetrating cells, and even crossing the blood-brain barrier, hydrogen can repair and protect our DNA, and enhance mitochondrial health.

What’s so great about hydrogen water, as opposed to ‘normal’ water?

The list is long, but these are just some of the potential benefits:

  • Reduced oxidative stress
  • Increased antioxidants
  • Weight loss
  • More balanced glucose levels
  • Better performance in sports
  • Improved Heart Rate Variability (HRV)
  • Higher VO2 max
  • Improved mood and quality of life
  • Improved gut microbiota
  • Skin improvement

Is hydrogen water safe?

Completely! Studies have proven that you cannot ingest too much – anything more than your cells need is just expelled through your breath. It has been suggested that the more hydrogen you consume, the greater the benefits – this is called the ‘dose-dependent effect’.

How much hydrogen is in HtoEau® hydrogen water?

Well, we are very proud to say that, thanks to our science whizz, Donny, we have packed an unrivalled 3ppm into each can – far more than other pure, molecular hydrogen waters out there! This means that you are getting more for your money, and potentially maximising the benefits to your body.

How did you get your ppm so high?

Sorry, but that is a very closely-guarded secret that Donny won’t even share with the rest of the team!

Why is a higher PPM favourable?

Because we are all unique, and some may require higher levels of hydrogen to do the good work. Considering the dose-dependent effect, it is advantageous to reach the highest levels we can, in order to give you optimal benefits.

What makes your water different to tablet-infused hydrogen water?

Good question! Well primarily, the H2 supplements that you add to water are in tablet or powder form and, therefore contain certain compounds in order to form the Hydrogen (and sometimes sugars). HtoEau® hydrogen water, not only gives you the benefit of drinking pure glacial water, but also pure, unadulterated hydrogen molecules, just like nature made them. That has to be an advantage!

How much should I drink?

1-2 litres per day is the optimum amount, but it’s fine to drink more if you wish.

Do I need to keep it chilled?

You can keep the water in or out of the fridge, and it can be consumed chilled or at room temperature.

Does it have a taste or smell?

Hydrogen is a colourless, tasteless, odourless gas and therefore all you will taste in HtoEau® is our pure, refreshing, glacial water.

How long will the hydrogen stay in my can?

We have seen that the levels of hydrogen deplete one hour after opening the can, so in order to get the most out of HtoEau® hydrogen water, drink it as soon as you can!

What does the research say?

There are numerous potential benefits to be gained from consuming and using hydrogen-rich water:


Studies have shown that skin healing was expedited significantly when applied to damaged skin. Further research proved that hydrogen water diminished wrinkles by increasing type-1 collagen production and reducing keratin damage. The anti-aging effects on damage to periodontal tissue have also been observed. Please click here, here  and here for the full reports.

Molecular hydrogen as an antioxidant

A report by Ohsawa et al. (2007) was the first to demonstrate that molecular hydrogen acts, at least in part, as an antioxidant, as it binds to hydroxyl ions produced in central nervous system injuries. Read more here.

One of the advantages of hydrogen water is the ability to cross the blood-brain barrier, offering high potential to reduce oxidative stress in the brain. A study found that levels of a marker of oxidative stress were almost 5 times higher in the brain than in the blood. This suggests that hydrogen water may reduce oxidative stress in the brain in daily life, potentially contributing to the maintenance of central nervous system activity and preventing decrease in quality of life.

The impact of hydrogen on Alzheimer’s

Another study related to Alzheimer's disease, showed that hydrogen-rich saline prevented neuro-inflammation and oxidative stress, and improved memory function. Read more here and here.

The positive effect on mood and quality of life

Drinking hydrogen-rich water has been proven to affect not only physical conditions, but also mental conditions such as mood, anxiety, and autonomic nerve function. Read more here.

Hydrogen water administration succeeded in suppressing depression-like behaviours, reducing oxidative stress and inflammation of the central nervous system. Read more here.

The association between hydrogen water and quality of life was exhibited in a study of patients treated with radiotherapy for liver tumours. Read more here.

Potential weight loss and cholesterol levels

Research into metabolic syndrome – which is associated with risk factors such as obesity and dyslipidaemia and hyperglycaemia - showed that molecular hydrogen significantly reduced blood cholesterol and glucose levels, as well as BMI (body mass index) and waist-to-hip ratio. In other words, the subjects that drank the hydrogen water lost weight and inches! Read more here.
