FAQs

Hydrogen water or hydrogen-rich water (also called hydrogen-enriched water) simply means normal water (H2O) that contains dissolved hydrogen gas (H2). For example, there are carbonated waters or beverages (soda pop), which contain dissolved carbon dioxide gas (CO2), or oxygen water, which contains dissolved oxygen gas (O2). Similarly, you can have water that contains dissolved hydrogen gas.


The water molecule has two hydrogen atoms, chemically bound to the oxygen atom. This is different from the hydrogen gas molecule (H2), which is just two hydrogen atoms bound only to each other.

Here’s an example: we need oxygen (O2) to live, so why can’t we just get our oxygen from drinking water, H2O? It’s because the oxygen is chemically tied up in the water molecule. We need available oxygen gas, (O2) that is not bound to other atoms or molecules. In the same way, in order for the dissolved hydrogen gas (H2) to benefit us, it must be in an unbound form, and therefore available for therapeutic benefit.


Hydrogen water has a pH of around 8 – 9, which is far more alkaline. This makes a difference.

Drinking hydrogen-rich alkaline water from a hydrogen water machine can pay significant dividends when it comes to your health and well-being.


The earliest account of hydrogen gas having medicinal properties was in 1798, for things like inflammation. But, it didn’t become a popular topic among scientists until 2007, when an article about the benefits of hydrogen was published in the prestigious journal of Nature Medicine by Dr. Ohta’s group.


Great question! If the water is rich in positive hydrogen ions (H+), then yes it IS acidic. But in this case, we’re talking about neutral hydrogen gas (H2), which is two hydrogen atoms tied together.

It can be confusing to hear “hydrogen water” because we usually think of hydrogen (meaning the hydrogen ion, H+) as acidic, and that is basically the definition of pH. The p stands for potential or power, meaning a mathematical exponent (in this case a logarithmic function), and the H stands for the hydrogen ion, which is just a proton and no electron. So pH literally means the logarithmic concentration of the hydrogen ion.

But when we say “hydrogen water” we are referring to dihydrogen or molecular hydrogen, which is a neutral gas that is dissolved in the water.


Yes, it does immediately start coming out of the water, but it doesn’t just vanish immediately. Depending on the surface area, agitation, etc., the hydrogen gas can stay in the water for a few hours or longer before it drops below a therapeutic level. This is much like carbonated water or soda that contains carbon dioxide gas (CO2), but because it does leave, it is best to drink the water promptly before it goes “flat”.


Yes. Hydrogen gas has been shown to be very safe at concentrations hundreds of times higher than what is being used for therapy. A good example of its safety is that hydrogen gas has been used in deep sea diving since 1943 (at very high concentrations) to prevent decompression sickness. Studies have shown no toxic effects from hydrogen when at very high levels and pressures of 98.87% H2 and 1.26% O2 at 19.1 atm.

Furthermore, hydrogen gas is natural to the body because after a fiber-rich meal, our gut bacteria can produce liters of hydrogen on a daily basis (which is yet another benefit from eating fruits and vegetables).

In short, hydrogen gas is very natural to our bodies, not like a foreign or alien substance that can only be synthesized in a chemistry lab.


Depending on water source conditions, the pH can range from 7.5-8.5. Production of Hydrogen water raises the pH of water by , making the water slightly alkaline.


Everything contains hydrogen. It is the most abundant element in the universe. However hydrogen is usually bound to other atoms and molecules and therefore not available purely as H2.

Just as we don’t get oxygen from H2O, we don’t get H2 from water. This is because H2 and O2 in H2O are not available because they are chemically bound to the water molecule. When used therapeutically hydrogen is dissolved into water in its molecular form, H2.


Because hydrogen is a very powerful antioxidant that helps to neutralise free radicals and reduce oxidative stress, which is a cause of most of illnesses and premature ageing. As well as hydrogen, which is the smallest element in the universe, it penetrates parts of the body where other antioxidants cannot reach, such as the neurons and the cell nuclei.


When you drink it you will notice it has a more atomised, lighter taste, so it does have a subtly different flavour.


Just as carbonated drinks start to gas off as soon as the lid is removed, H2 will start to escape immediately. Similarly, it takes time for all of the dissolved H2 to escape from water. For best results, hydrogen-rich water should be consumed as fresh as possible, or stored in an air tight glass or metal container (aluminium or stainless steel) that is filled to the brim.


No. Even if you drink hydrogen water, vitamins and antioxidant minerals in food are necessary, because they have other vital functions, apart from the antioxidants themselves.


Depending on your home, work and lifestyle choices, there are many potential ways that hydrogen rich water may enhance your health and wellness.
It has been documented through hundreds of studies that molecular hydrogen may have the potential to improve athletic performance and recovery, energy levels, jet lag, hangovers, anti-aging, allergies, skin irritation, inflammation chronic diseases such as many chronic diseases such cancer, diabetes, cardiovascular, neurological, pulmonary diseases. Hydrogen water has been proven as effective antioxidant therapy.


Right from the start you will notice you have more energy, are better hydrated, with improved general well-being, better digestion and better quality rest. But if you are talking about important improvements, you will only notice these after a few weeks or even months, if you manage to reduce oxidative stress, which is the cause of most illnesses and premature ageing.


No. hydrogen water has zero calories.


The body refuses to convert energy into food when our oxidation levels are high, because burning fat causes even more oxidation. The antioxidant charge of hydrogen water helps us to lower the level of oxidation, enabling the metabolism to transform fat into energy. However, the body never loses fat deposits unless we burn more calories than we consume.


No. However long you hydrogenate the water, it is impossible to overload it with hydrogen. Once it becomes saturated, any excess just evaporates. What’s more, however much hydrogen saturated water you drink, you’ll never reach the recommended maximum.


Yes. The only effect of hydrogen-rich water is to help to maintain a suitable oxidation level for good health. It has no contraindications.


The recommended daily water intake is between two and three litres. We recommend that you drink only hydrogen water, although anything more than one glass a day will be highly beneficial for regulating your oxidation level.
