FAQ

About Opal Hydrogen Water

What is hydrogen water?

Hydrogen water is regular water (H₂O) that has been infused with dissolved molecular hydrogen gas (H₂). The dissolved hydrogen molecules act as a selective antioxidant in the body, targeting the most harmful free radicals — particularly hydroxyl radicals — without interfering with beneficial reactive oxygen species your body needs.

How is Opal Hydrogen Water different from regular water or alkaline water?

Unlike alkaline water, which simply changes the pH of your water, Opal Hydrogen Water delivers dissolved molecular hydrogen — the actual therapeutic molecule backed by over 1,000 published scientific studies. Our hydrogen water is produced using an electrolysis method with zero chemical additives or residues, meaning what you get is pure hydrogen-enriched water, nothing else.

Is there actual science behind hydrogen water?

Yes. There are over 1,000 peer-reviewed studies on molecular hydrogen and human health, including randomised controlled trials (RCTs) across areas such as sports recovery, inflammation, metabolic health, cognitive function, and more. Opal Hydrogen Water is produced to therapeutic hydrogen concentrations consistent with those used in clinical research.

Products & Usage

What products do you offer?

We offer a range of products to suit every lifestyle: our 250ml Can — ready-to-drink, perfect for on the go; our 1.5L Bag — ideal for daily drinks, gym sessions, or taking out and about; our 5L Bag — great for home use, families, or refilling throughout the day; and our Starter Pack (10 cans + 1 x 5L bag) — perfect for first-time buyers who want to try both formats.

How much hydrogen is in each can?

Our 250ml cans are produced to contain hydrogen at therapeutic concentrations (typically 1.0–1.6 ppm dissolved hydrogen). Exact levels may vary slightly by batch due to the nature of dissolved gas, but all cans are produced to meet or exceed the levels used in published clinical studies.

When is the best time to drink hydrogen water?

There is no single "best" time — hydrogen water can be consumed any time of day. Many customers drink it first thing in the morning, before or after exercise, or during periods of stress or mental fatigue. For best results, drink it promptly after opening, as dissolved hydrogen dissipates over time once exposed to air.

Can I drink it every day?

Yes. Hydrogen water is safe for daily consumption. It is simply water with dissolved hydrogen — there are no stimulants, additives, or chemicals involved. Many of our customers incorporate it into their daily health routine.

Is it safe for children or pregnant women?

Hydrogen water contains no additives and is generally considered safe. However, as with any health product, we recommend consulting your healthcare provider before use if you are pregnant, breastfeeding, or giving it to young children.
