FAQ — SULI Hydration

Your Questions, Answered

Hydrogen water is regular water (H₂O) that has been infused with extra dissolved molecular hydrogen gas (H₂). Think of it like carbonated water - except instead of CO₂ bubbles, you're getting dissolved hydrogen molecules your body can actually use.
Yes - but that hydrogen is chemically bonded to oxygen in the H₂O molecule. In hydrogen water, there are free-floating H₂ molecules that are not bound, which is what allows the body to absorb them and benefit from their antioxidant properties.
Hydrogen water has a subtly lighter, more "smooth" taste compared to regular water - often described as feeling more refreshing without any metallic or mineral aftertaste.
Hydrogen water can be produced through electrolysis, direct pressurized infusion, or Mg reactions. Pre-packaged products like SULI use sealed containers to maintain the hydrogen concentration so it reaches you at full potency

Research suggests molecular hydrogen acts as a selective antioxidant — it targets harmful free radicals (like hydroxyl radicals) without disrupting the body's beneficial processes. Potential benefits backed by studies can be seen on our Health Benefits page above.
There's a growing body of evidence. Over 1,000 studies have been published on hydrogen water since 2007, and over 100 clinical studies have demonstrated its therapeutic potential across a variety of conditions.
Early research does support hydrogen water's role in reducing lactate buildup and muscle fatigue after exercise. It works by neutralizing the excess free radicals that build up during intense physical activity, which supports faster recovery.
No - and SULI doesn't claim to be. Hydrogen water is a wellness tool supported by science, not a replacement for medical care, nutrition, or exercise. It's best understood as a premium daily hydration upgrade that supports your body through numerous health effects.

Yes - molecular hydrogen shows no known toxicity, even at elevated quantities. Your body naturally expels any excess hydrogen through your lungs, so it doesn't accumulate. It is generally recognized as safe for all healthy beings.
There is no established upper limit for hydrogen water intake because your body simply breathes out the excess. The hydration risk is the same as regular water, drink according to your body's needs.
Currently, there is no evidence that hydrogen water negatively interacts with any medications. If you have specific health conditions or concerns, consulting your doctor is always a good idea.

These are two different things. Alkaline water has a raised pH (typically 8–9.5) due to added minerals; hydrogen water has a neutral pH and its benefit comes entirely from dissolved H₂ molecules acting as antioxidants. SULI is hydrogen water - not alkaline water.
Regular water is excellent for hydration - and SULI delivers all of that plus molecular hydrogen's antioxidant benefits. Think of it as regular water with a meaningful wellness upgrade to supercharge your cells.
Most enhanced waters add vitamins, electrolytes, or flavours. SULI's hydrogen infusion works at a molecular, cellular level - targeting free radicals rather than just supplementing micronutrients.

The effectiveness of hydrogen water is tied to its concentration, measured in PPM (parts per million). The International Hydrogen Standards Association (IHSA) sets the minimum effective dose at 0.5 mg of hydrogen per serving. Studies showing real benefits typically use concentrations at 1.6 PPM. SULI is formulated to deliver a therapeutically meaningful dose.
Packaging matters a lot for hydrogen water. Hydrogen gas escapes quickly from plastic containers, while aluminum is far less permeable, helping retain H₂ concentration longer. A properly sealed aluminum can is one of the best formats for delivering hydrogen water at effective levels right to the consumer.
Once opened, hydrogen starts escaping immediately. For the best experience, drink SULI shortly after opening - ideally within 30 minutes - to get the full antioxidant benefit. Treat it like sparkling water: fresh is best.
Cooler temperatures help hydrogen stay dissolved longer. Refrigerating SULI before drinking will preserve its hydrogen concentration and enhance the drinking experience - though the sealed can protects H₂ until it's opened.
SULI is currently offered in three flavours: Juneberry, Orange-Vanilla, and Italian Lemon. We are always exploring new flavours and opportunities, so we would love to hear suggestions from you. Please fill out our contact form with your ideas and we will send you test samples if your flavour is chosen!

The name SULI comes from the Roman-Celtic Goddess of healing water - Sulis. We started to bring the healing benefits of hydrogen to all - more about this can be seen in our “About” section.
SULI is currently working towards a lunch with hopes of bringing our product to a shelf near you at the end of 2026. If you have an office or facility that you would like SULI in, please reach out so we can send some over for you to try!
Our packaging is fully recyclable and we are exploring opportunities to help fund sustainable projects in the industry and make our company a leader in supporting our home. More information can be found on our “SULI Supports” page.
SULI is designed for anyone seeking better hydration and health - athletes, busy professionals, health-conscious individuals, and people who just want a daily wellness habit. The anti-inflammatory and recovery benefits make it especially appealing for active lifestyles.
