Regular water (H₂O) with extra molecular hydrogen (H₂) dissolved in it - like how carbon dioxide is added to fizzy drinks. The hydrogen isn't bound to the water molecule; it's free-floating gas that has been the subject of over 1,400 published wellness studies

Yes, but it's chemically bound to oxygen (H₂O). Your body can't use bound hydrogen. Hydrogen water contains FREE molecular hydrogen (H₂) dissolved in the water - small enough to be absorbed quickly by the body

Yes. Molecular hydrogen is classified as Generally Recognised As Safe (GRAS) and has been used in hospitals in Japan for decades. Our bottle uses food-grade, BPA-free materials. No known side effects.

Fill with tap or filtered water, press the button once (5-min mode) or twice (10-min mode), wait for the cycle to finish. Drink immediately for best results, or within 30 minutes.

Any tap water or filtered water works perfectly. Filtered is always preferred, as it allows for higher hydrogen concentrations. Tap water is however okay as the bottle purifies it during the hydrogen generation process by venting out chlorine and other byproducts.

Most customers report feeling a difference within the first week or two. As with any wellness routine, individual experiences vary - some notice changes quickly, others find it builds gradually over consistent daily use. We recommend trying it for at least 30 days as part of your daily routine.

Once a week for typical daily use (2-3 bottles per day). Each charge lasts 12-15 cycles. Charges fully in 2-3 hours using any USB-C cable.

You're covered by our 60-day money-back guarantee. If you don't feel the difference, just return it for a full refund - no questions asked

You'll see tiny bubbles (like champagne) during the cycle, and the water will have a slightly smoother taste. For verification, you can use H2 Blue test drops (available separately) to confirm hydrogen concentration.

No - heat destroys the molecular hydrogen. Use it with cold or room temperature water only. The hydrogen stays effective for about 30 minutes after generation, so drink it fresh for best results.
