A note before we start. X2O is a general-wellness hydration product and is not intended to diagnose, treat, cure or prevent any disease. None of these waters is a medical treatment. This is not medical advice.
Alkaline, hydrogen and light-infused water get lumped together, but they rest on different mechanisms and very different evidence. Here’s each one, separated from the marketing.
Key takeaways
- Alkaline: weak case; your body regulates blood pH tightly.
- Hydrogen: a real research area; small studies, mixed results.
- Light-infused: LifeWave’s patented process; no independent evidence.
- Volume and consistency of plain clean water beat all three.
Alkaline water
Water with a pH above 7, from ionisation or added minerals. Your lungs and kidneys keep blood pH in a narrow range, and stomach acid neutralises what you drink. The mainstream view is that healthy people don’t need pH help from a drink. One footnote: ionisers often produce some dissolved hydrogen, which may be what some users are responding to.
Hydrogen water
Dissolved H2, studied as a selective antioxidant, including for oxidative stress and exercise. There’s a coherent rationale, but the trials are mostly small and short with mixed results. See hydrogen water benefits and hydrogen water explained.
Light-infused water
LifeWave’s patented process, available only through X2O. The company says it carries light into the body. It draws on ideas from biophotonics, but there’s no independent evidence that water stores light or that drinking it has any effect. See what is light-infused water?
Which should you choose?
- Don’t pay a premium for alkalinity alone.
- If you’re curious about hydrogen, try it cheaply first with tablets or a bottle.
- Light-infused water is for people comfortable paying for an unproven idea. X2O also filters and adds hydrogen; filtration is the part with clear value.
- Whatever you choose, drinking enough clean water matters most.

Is alkaline water better than regular water?
The evidence doesn’t support meaningful benefits from alkalinity itself.
Is hydrogen water better than alkaline?
It has a stronger rationale, but its benefits aren’t established either.
What is light-infused water?
LifeWave’s term for X2O-processed water. Its effects are unproven.
Which has the most research?
Hydrogen water, though it’s still early.
Does X2O treat any condition?
No. No such claim is made. It is not intended to diagnose, treat, cure or prevent any disease.
