How long does hydrogen water last in a glass?

Hydrogen water is drinking water with dissolved molecular hydrogen, H2. Hydrogen is a gas, and it starts to leave open water the moment the glass is made. So how long does hydrogen stay in water? We won't give you a minute count we can't back up. What we can say is simple. The longer a glass sits, the less hydrogen is left in it. That's what people mean when they ask if hydrogen water goes flat. The fix is to drink it within a few minutes of making it. Should you drink all your hydrogen water at once? Yes. Finish the glass then, rather than sipping it through the morning.

Stored hydrogen water vs a glass made fresh

How you get hydrogen water decides how fresh it is. Cans and pouches are filled ahead of time. They're only as fresh as their packaging and shelf time allow. A machine or bottle makes it on the spot. You still drink it from the jug or bottle rather than saving it. A tablet works in any glass, at home, at work or in a hotel room. You carry the tablets, and they're TSA-friendly. That's how to store hydrogen water in practice. Keep the tablets, and make each glass when you're ready to drink it.

How our tablets make every glass fresh

Each Clover & Young tablet stays sealed in its own blister pack until you open it. Drop it in water and its 40 mg of magnesium reacts with the water, releasing hydrogen gas. In 90 to 120 seconds, one tablet makes 10+ PPM of molecular hydrogen in 12 oz. So the hydrogen is made right before you drink, with nothing stored. Hydrogen content is tested by H2 Analytics, an independent lab. The tablets are made in an FDA-registered, GMP-certified facility, with zero sugar, caffeine and calories. To compare any tablet's label, read our guide to H2 tablets.

How to drink hydrogen water while it's fresh, step by step

  1. Make it. Pour 12 oz of still water and drop in one tablet straight from its blister.
  2. Wait 90 to 120 seconds while it fizzes. The fizz is the hydrogen being made.
  3. Drink it within a few minutes of the fizz stopping. Finish the whole glass.
  4. Make the next one fresh. Want another glass later? Use a new tablet.

And what not to do:

  • Don't make a glass ahead and leave it for later.
  • Don't sip one glass over an hour.
  • Don't store an opened glass or bottle to finish tomorrow.

How much to drink each day is its own question. For the amounts studies used, see how much hydrogen water per day. Try a fresh glass daily for 90 days. If you don't feel the difference, we refund every dollar, and you keep the tablets.
