What is Hydrogen Water?

Hydrogen Water or hydrogen rich water (also called hydrogen enriched water) simply means normal water (H2O) that contains dissolved hydrogen(H2)

Isn’t that we learnt in school hydrogen is explosive and release a pop sound when we do experiment in school laboratory?

Yes, it is very explosive, however, when the gas is dissolved in water it is not explosive at all.

Just like mixing a gunpowder in water. It would not be explosive either. It is only flammable when it is in air.

Water is H2O. Doesn’t water already have hydrogen in it?

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 is an example:

We need Oxygen (O2) to live, so why can’t we just get our oxygen from drinking water h20? The oxygen is chemically tied up in the water molecule. We need available oxygen gas, (o2) that is not bonded to other atoms or molecules. By the same means, we need the available hydrogen gas (h2).

This is why water is also not explosive although it contains hydrogen.

Won’t any dissolved hydrogen gas immediately escape out of the water?

Yes, it does immediately start coming out of the water, but it does not 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”

What is the pH of hydrogen water?

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

Normal water has hydrogen, what makes this different?

In normal water, two hydrogen atoms are bound to Oxygen (H₂O) making it difficult for our bodies to enjoy the benefits of Hydrogen. In hydrogen rich water, molecular hydrogen gas (H₂) is dissolved into water creating free, active hydrogen atoms that are accessible to our bodies. Molecular Hydrogen, small and soluble, has the potential to quickly circulate into many locations of our body, including the hard-to-reach powerhouses of our cells.

How much water should I drink?

The recommended daily water intake is between one and three liters. 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.

Is it recommended for cooking?

No hydrogen evaporates easily.

Is it possible to take overdose of Hydrogen Water?

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.

Are there any calorie in hydrogen water?

No. Hydrogen water has zero calories.

When do I start noticing the effects of the hydrogen water?

Right from the start you will notice you have more energy, are better hydrated, with improved general well-being, better digestion, 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.

Is hydrogen water the same as alkaline water?

No. Alkaline water has large quantities of minerals dissolved in it, and it does not normally have an electric charge or contain active hydrogen. Only “ionised alkaline” water has an antioxidant electric charge and some dissolved hydrogen, although most of the electric charge comes from the ionised minerals, which do not have a useful antioxidant charge. The excess minerals in this type of water and its high pH, that come from ionised minerals mean that “ionised alkaline water” is not recommended as a long-term water choice.

Can babies and pregnant women drink hydrogen water?

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

Does it have any effects when applied to the body, skin, and scalp?

Yes. It eliminates free radicals from the skin. Hydrogen water can be applied with a cloth or directly to the skin and left to work for a few minutes.

Can drinking hydrogen water helps me in weight loss?

The body refuses to convert energy into food when our oxidation level is 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.

Does drinking hydrogen water affect our stomach pH?

Hydrogen has no influence on pH. Hydrogen is neutral gas, so it’s neither alkaline nor acidic. When you drink hydrogen water, the H2 molecules does not dissociate into protons and electrons. It is stable molecule. It is absorbed by the body and enters the blood stream.

Why does drinking hydrogen water gives more energy?

When our level of oxidation is high, the body refuses to convert food into energy, because this further increases the oxidation. The antioxidant charge of hydrogen water helps to adjust the level of oxidation in the body, which enables food to be converted into energy, instead of being stored as fat.
