How long does molecular hydrogen stay dissolved in water?


Imagine you pour a carbonated drink like soda into a glass and let it sit for some time. At some point, all carbon dioxide (those bubbles of gas) will dissipate back into the air and you will no longer feel it buzzing on your tongue when drinking it.

If you, however, keep the original packaging unopened where the carbon dioxide is kept under the right amount of pressure, its presence in water will last for much longer.


H2 is a gas


The same principle applies to molecular hydrogen (H2 or also called hydrogen gas), which forms nano bubbles when dissolved in water (it might be useful you also check out our blog post called 'How to produce molecular hydrogen (H2)' ).


From a therapeutic perspective, the reason why we're interested in the dissolved H2 in water is that when you get it into your stomach it's able to reach the gut and get absorbed through intestinal wall into the blood stream and into your cells.


We can measure dissolved H2 through either using an H2 meter or H2 blue reagent (more on this topic in another upcoming blog post).


Designed to be drunk fresh from the tap


Hydrogen-rich water technology is generally designed to provide households, offices, gyms or yoga studios (etc.) with filtered clean fresh hydrogen-rich water on tap. The actual hydrogen-rich water produced this way isn't to be sold with the intention of having a long shelf-life.



Why? Because hydrogen gas isn't really designed for long-term storage and long shelf-life. That's why, in order to get the most of the therapeutic benefits of H2, drinking fresh hydrogen-rich water on tap, produced by a unit, will be the most convenient and efficient alternative. 


Many people, including myself, will still not have access to their water machine outside of their home or place of work or recreation. And here's the question: Will it help to carry a bottle of hydrogen-rich water with you? Will last last long enough when going on holiday for couple of days?


The answer is: You're all good. Yes, it will!


How long the dissolved H2 lasts in your water depends on three factors:


1/ Exposure to air

2/ Container material

3/ Temperature


1/ Exposure to air


When poured into a pint glass ( roughly 20 US ounces) of water, the hydrogen can easily last for a few hours and H2 will eventually dissipate. Our assumption is, however, that it doesn't take you a few hours to drink that much water so you're fine with that one :-)


Closed container is much better for keeping the hydrogen in longer.


2/ Container material


The best materials to use for hydrogen-rich water storage are high quality stainless steal and glass. Plastic wouldn't be my personal favourite, but if you there's no other option, choose a higher quality BPA free bottle.

If you fill up your water bottle all the way to the very top with no air space in it and you put a nice lid on it that seals very well, you can keep the hydrogen for up to 10 days.


You need to keep in mind, however, that because it's a gas, it's going to decrease each day - roughly by .1 parts per million (ppm) when kept in a cool environment with no direct sunlight. So if you start at 1ppm on day one, on day eight you may only have .2 parts per million dissolved H2. By day ten you may have lost all of your hydrogen or you may not.


3/ Temperature


We said "you may not lose all the hydrogen by day 10" because it depends on the temperature of the water. The colder the water, the slower the hydrogen gas moves. For that reason it may be best to keep your bottle in a fridge. 


And the practicality of it all? If you have a hydrogen-rich water machine at home already or you're planning to get one, don't get too hung up on it all. Worrying, stress and anxiety can do much more damage to your body than happily enjoying a clean glass of water even with very little or no hydrogen in it! :-)
