Molecular Hydrogen Tablets - Unflavored
Our Molecular Hydrogen Drinking Tablets transform ordinary water into hydrogen-rich water, delivering a potent 12 ppm dose that supports whole-body wellness at the cellular level.
CELLULAR HEALTH*
ENERGY + FOCUS*
GUT HEALTH*
PERFORMANCE + RECOVERY*
Molecular hydrogen works at the body's foundation: the cells. By promoting healthy cellular function, it provides 40+ researched benefits that support nearly every system in the body. That's why molecular hydrogen is backed by thousands of scientific studies and trusted by scientists and healthcare professionals alike.*
Each package of Molecular Hydrogen Drinking Tablets contains 30 magnesium-based tablets that dissolve in water to release billions of nanobubbles filled with pure molecular hydrogen gas. Highly bioavailable, molecular hydrogen rapidly absorbs into the bloodstream and penetrates deep into your tissues and cells. At the cellular level, it helps neutralize harmful free radicals and restore internal balance—supporting the foundation of how we perform, repair, and function.
Taken daily, Molecular Hydrogen Drinking Tablets may support energy, mental clarity, physical performance, muscle recovery, and gut health—delivering whole-body benefits in a convenient format that fits seamlessly into everyday life.*
Drop 1 tablet into 12–16 oz of room-temperature water and let it fully dissolve (approximately 90–120 seconds). Drink immediately for maximum hydrogen gas concentration. Finish within 20 minutes of the tablet dissolving.
We recommend starting with 1 tablet per day. Increase to 2–3 tablets as needed. For best results, take daily.
+ Do not swallow tablets directly.
+ Store tablets at room temperature.
Elemental magnesium, dextrose, malic acid, tartaric acid, adipic acid.
No fragrance, dyes, or artificial additives.
H2Tab are primarily made from elemental magnesium: the key to generating pure molecular hydrogen. When dissolved in water, our tablets create a clean and highly effective reaction, releasing ultra-pure hydrogen gas.
To optimize this process, we use a carefully selected blend of natural acids—malic acid (found in apples), tartaric acid (found in grapes), and adipic acid (found in sugar beets)—which help break down the magnesium and activate hydrogen production. We also include a small amount of non-GMO dextrose, serving as a binder to hold the ingredients together.

WHY IS IT IMPORTANT?
Known as the 'second brain,' the gut is a cornerstone of health, influencing numerous physiological processes, with the microbiome being one of the key components.
HYDROGEN'S IMPACT
Studies show that drinking hydrogen-rich water can help reduce stress in your gut, strengthen its defenses, and support a healthier balance of gut bacteria, all of which lead to better digestive health.

WHY IS IT IMPORTANT?
Every day, your body fights off harmful molecules called free radicals. Free radicals come from things like pollution, stress, and even the food you eat. When your body has too many of these free radicals, it causes something called oxidative stress. This causes damage to your cells and can lead to a variety of diseases.
HYDROGEN'S IMPACT
Hydrogen acts as a powerful antioxidant, neutralizing the harmful molecules in your body.

WHY IS IT IMPORTANT?
Increasing absorption in the gut is crucial because it ensures the body efficiently utilizes nutrients from food or supplements, to support overall health. It enhances energy levels, boosts immune function, and promotes digestive health.
HYDROGEN'S IMPACT
Molecular hydrogen enhances nutrient absorption by reducing oxidative stress, which can improve nutrient uptake and support a balanced gut microbiome. By creating a healthier gut environment, it helps your body absorb vitamins and minerals more efficiently, maximizing the benefits of the nutrients you consume.

H2 Tabs
I like the tabs and ordered some for my sons.
It works!
I was skeptical at first. Not that I disbelieved the health benefits, I just wasn't sure it would make any noticeable difference. But it works. I definitely noticed more energy and focus when taken first thing in the morning.
Small boost of energy
So far I've noticed a little boost in energy after I take these. I'm taking them about 3 times a week.
Feel the Difference
I feel more energized and clear. I notice a big difference in my endurance and strength when exercising. I am very happy with H2Tab, will continue to take them everyday.
5 Stars
Amazing.
Tastes great!
I love how quickly it dissolves and tastes great.
