How Long Does Hydrogen Water Last?

A Comprehensive Guide to Maximizing Benefits

Hydrogen water, infused with molecular hydrogen gas (H2), is gaining attention for its potential antioxidant and therapeutic properties. But understanding its shelf life and how to maximize its benefits is crucial. Let's delve into the science behind hydrogen water and its storage.

Key Takeaways:

  • Hydrogen water loses potency over time due to the volatile nature of H2 gas.
  • Proper storage in airtight containers, preferably made of glass, Tritan or aluminum, is essential.
  • Consume hydrogen water within a few hours of opening for optimal benefits.

Factors Affecting Hydrogen Retention

  • Temperature: Higher temperatures increase the rate of hydrogen gas escaping the water.
  • Light Exposure: UV light can break down H2 molecules, decreasing its concentration.
  • Container Type: Glass, Tritan and aluminum are the best materials for preserving hydrogen water due to their non-porous nature. Regular plastic can allow H2 gas to permeate, shortening the water's shelf life.

Ideal Storage Conditions

To maximize the lifespan of hydrogen water:

  1. Store under pressure in airtight containers: This prevents hydrogen gas from escaping. As soon as you open your hydrogen water generator, the pressure will be released and the concentration will start lowering. You need to drink the water in the next 20 minutes for maximum benefits. If you don't open the pressurized container, the hydrogen water will be good for the next 2 days.
  2. Store in a cool, dark place: A refrigerator is ideal, as lower temperatures slow down the H2 gas dissipation. However do not store the hydrogen generator in the fridge. This option if good only if you transfer the water in a airtight glass bottle and store it in the fridge.
  3. Choose the right container: Opt for glass or Tritan bottles to minimize hydrogen loss.

Hydrogen Water Lifespan

  • Sealed Containers: In a properly sealed glass or aluminum container, without any air gap, hydrogen water can retain its potency for several hours to days, depending on the initial concentration of H2.
  • After Opening: Once opened, the hydrogen concentration will rapidly decrease as H2 escapes into the air. It's recommended to consume the water within a few hours for maximum benefit.

Enhancing and Preserving Benefits

  • Use cold water: Use cold water from your fridge as cold water stores more hydrogen and keeps it for longer.
  • Use High-Quality Containers: Invest in glass or Tritan bottles designed for storing hydrogen water.
  • Consume Quickly After Opening: Drink your hydrogen water soon after opening to enjoy its full potential.


Q: What is hydrogen water?

A: Hydrogen water is simply water enriched with molecular hydrogen gas (H2).

Q: How long does hydrogen water last?

A: Unopened, properly stored hydrogen water can last from 8 hours to 2 days. Once opened, consume within a few hours for best results.

Q: How can you tell if hydrogen water has lost its effectiveness?

A: The "Pssst" sound typical for opening a can of soda is the only indicator that there is still hydrogen gas in the water. If not, generate yourself a new batch.

In Conclusion

Hydrogen water can be a valuable addition to a healthy lifestyle, but understanding its storage and consumption is key to maximizing its potential benefits. By following these guidelines, you can ensure you're getting the most out of your hydrogen water. Remember, freshness is crucial when it comes to enjoying the full effects of this unique beverage.
