Drop
Place one tablet in 10–12 ounces of water. Use drinking water; the tablet does not filter or purify it.
Active H2 Ultra · Water & Wellness
The Simplest Way to Upgrade Your Water
Make fresh hydrogen water with one tablet. Choose Unflavored in our new 60-tablet bottle or a mild Raspberry flavor in 30- and 60-tablet blister packs. Just drop, dissolve, and drink.
Same great product — new packaging!
Unflavored 60ct now comes in a bottle.
Start with the basics
Your water already contains hydrogen. So what’s different?
In ordinary water, hydrogen is bound to oxygen as H₂O. Hydrogen water also contains molecular hydrogen gas—H₂. Active H2 tablets generate this gas when they react in water.
H₂O · Water
Hydrogen bonded to oxygen
H₂ · Molecular hydrogen
Two hydrogen atoms joined together
Illustration of molecular structure; not to scale.
A very small molecule. A growing field of research.
Hydrogen is the lightest element. Two hydrogen atoms form H₂, the lightest molecule. Its small size lets it diffuse readily through biological membranes. Researchers are studying how it interacts with the body’s responses to oxidative stress and exercise.
Molecular size helps explain the scientific interest; it does not, on its own, establish a health benefit.
What happens in your glass
A tablet that makes hydrogen fresh.
The magnesium in Active H2 reacts in water, with the help of the formula’s organic acids, to produce molecular hydrogen gas. You prepare it when you’re ready to drink.
Dissolve
Allow the tablet to dissolve completely. The reaction generates hydrogen gas in the water.
Drink
Drink immediately after the tablet has dissolved. Hydrogen gas gradually escapes, so prepare each glass fresh.
Label directions: one tablet, 1–3 times per day. Follow the directions on your pack. Do not swallow the tablet whole.
Why molecular hydrogen?
Look beyond the bubbles.
The interest in hydrogen water comes from research into how the body responds to physical effort and oxidative stress. Here are three areas scientists have explored in people.
Exercise & muscle fatigue
Small trials have reported promising findings in muscle function and fatigue during exercise. Results vary with the activity and study design. [1]
Oxidative stress
Researchers have measured changes in antioxidant activity and blood-cell responses. Some findings are encouraging, while others show no difference from plain water. [2]
Metabolic health
A longer trial in adults with metabolic syndrome reported changes in several blood markers. This research is specific to that population and regimen. [3]
These studies investigate hydrogen-rich water. They are not presented as trials of Active H2 Ultra or a promise of individual results.
Find your everyday favorite
Two flavors. Three ways to stock up.
Prefer no added fruit flavor? Choose Unflavored. Like a little Raspberry? Choose a 30- or 60-tablet pack. All three make hydrogen water in an ordinary glass.

Why make it with a tablet?
Fresh hydrogen water. No machine required.
The original Active H2 idea is simple: make hydrogen water in an open glass, wherever you have drinking water.
No equipment to set up
A glass, drinking water and one tablet are all you need.
Easy to take along
Choose a bottle for your daily routine or individually sealed Raspberry tablets to take along.
Magnesium in every tablet
Each tablet provides 80 mg of magnesium—19% of the Daily Value shown on the label.

01Exercise and muscle functionAoki et al. · 2012 · 10 male soccer players
In a double-blind crossover pilot, hydrogen-rich water was associated with lower exercise-related lactate and less early decline in muscle torque. Oxidative-injury markers and creatine kinase did not significantly change. The small sample limits how broadly the results apply.

View original publication02Blood-cell responses and oxidative stressSim et al. · 2020 · 38 adults completing four weeks
Participants drank 1.5 liters daily of hydrogen-rich or plain water. Researchers observed differences in some blood-cell and inflammatory-response measures. Overall changes in several antioxidant and oxidative-stress markers did not differ between groups; one antioxidant finding was confined to an age subgroup.

This randomized trial reported improvements in several glucose, lipid and inflammatory markers with a specific high-concentration hydrogen-water regimen. It studied adults with metabolic syndrome, not a general healthy population. It does not establish weight-loss or disease-treatment benefits for Active H2 Ultra.

A randomized crossover study found that acute pre-exercise hydrogen-rich water did not improve running performance at maximal aerobic speed. Together with positive trials, this shows why the activity, dose and timing matter—and why a study result should not become a guarantee.

View original publicationStudy methods and hydrogen preparations differ. Laboratory markers are not the same as a noticeable health benefit, and findings from one formulation or population do not automatically transfer to another.
Explore the study summariesA few things worth knowing.
What does Raspberry taste like?
The formula has a mild raspberry flavor. It contains natural raspberry powder and Chinese blackberry extract.
What’s in each tablet?
Both Ultra flavors provide 80 mg of magnesium per tablet. Unflavored lists malic acid, dextrose, tartaric acid, adipic acid and sodium stearyl fumarate. Raspberry also lists natural raspberry powder and Chinese blackberry extract. See your selected product label for the full ingredient list.
Is hydrogen water the same as alkaline water?
No. “Alkaline” describes pH. Hydrogen water contains molecular hydrogen gas. A high pH alone does not tell you how much H₂ is in a drink.
Can I prepare a bottle for later?
Prepare each glass when you’re ready to drink. Allow the tablet to dissolve completely, then drink immediately, as directed on the label.
Is this a water purifier?
No. Active H2 generates molecular hydrogen in water; it does not remove contaminants. Start with water that is suitable for drinking.
What changed with Unflavored?
Same great product — new packaging! Unflavored 60ct now comes in a bottle instead of a box. Unflavored 30ct and Chromax remain out of stock. Raspberry is available in 30- and 60-tablet blister packs.
How does this fit with Quinton?
They serve different purposes. Quinton provides marine minerals and trace elements. Active H2 generates molecular hydrogen in water and provides magnesium. You can explore each as part of the Water & Wellness Terrain Protocol.
Clean water. Minerals. Molecular hydrogen.
Start with the water you drink, replenish minerals with Quinton, and explore Active H2 as the hydrogen part of your Terrain Protocol.
