Reviews
"I was skeptical at first, but after using hydrogen water regularly, I noticed that my digestion had significantly improved. This hydrogen bottle is so easy to use, just the right size, and the battery lasts for quite a while. I would definitely recommend using it for your health benefit."
"Because of sensitive guts, I often suffered from cramping pain in the abdomen. However, since I replaced all my drinking water with hydrogen water, I don't feel this pain anymore. Feeling free of this discomfort has greatly improved the quality of my life. Furthermore, the bottle is easy to use and of the right size."
"I have been drinking my hydrogen water after my tennis and gym sessions, and I do find that my recovery time is much faster than with regular water. All I need to do is make the water and keep it in an aluminum bottle. Easy!"
"Ever since I drank hydrogen water, I can feel the difference between drinking regular water and hydrogen water. Pretty much immediately after drinking hydrogen water, I don't feel as tired and have more energy. The H Fizz Bottle is so easy to carry and use, I take it pretty much wherever I go. Highly recommend."
"I have been using H-Fizz as my regular water bottle in the office and I've been drinking hydrogen water exclusively. I feel that it gives me more energy throughout the day, and watching the hydrogen bubbles during the preparation is quite therapeutic! Another benefit is that I end up drinking more water than before."
"I suffer from occasional eczema and sensitive skin conditions, but I find that after a month of drinking hydrogen water, my skin condition has improved overall. My skin feels more bouncy and supple."
"I tried inhaling hydrogen gas for an hour each day. At the end of each session, I feel I can breathe more easily and smoothly, my muscles are less tight, and I feel more relaxed. My mind also becomes clearer. It is a good way to end each day before bed."
"I am a stage 3 lung cancer patient, and I constantly struggle with breathing difficulty. I started inhaling hydrogen gas to help me reduce these symptoms. I can notice immediate ease with my breathing, helping me sleep and rest better. Most of all, this does not interfere with my regular treatments. Thank you for such a good invention!"
"I started using the H Fizz machine when I had the flu. It helped my symptoms and sped up the recovery process. I continued to use the machine to breathe hydrogen as it helps my concentration, energy, and overall health. Several friends told me it was the only product that helped them with their long COVID symptoms."
"I used the H Fizz Lite Machine when I had COVID. As my symptoms were very bad, I felt that the machine had helped me recover better and sleep better."

H Fizz® FAQs
Hydrogen Water
What is hydrogen water?
What is hydrogen water?
Hydrogen water (also called hydrogen-rich water) is regular drinking water infused with dissolved molecular hydrogen gas (H₂).
The hydrogen in hydrogen water is free molecular hydrogen gas, not the hydrogen chemically bound in H₂O.
Doesn’t water already contain hydrogen because it’s H₂O?
Doesn’t water already contain hydrogen because it’s H₂O?
No. The hydrogen in H₂O is chemically bonded to oxygen and is not available as molecular hydrogen gas.
Hydrogen water contains additional dissolved H₂ gas, which is the form studied in scientific research.
Is hydrogen water the same as alkaline water?
Is hydrogen water the same as alkaline water?
No.
Hydrogen water refers to dissolved molecular hydrogen gas.
Alkaline water refers to higher pH levels.
Hydrogen infusion does not necessarily change pH, and the research on hydrogen water focuses on dissolved H₂ — not alkalinity.
What are the health benefits of molecular hydrogen?
What are the health benefits of molecular hydrogen?
Research suggests molecular hydrogen may:
- Support the body’s response to oxidative stress
- Help regulate inflammatory signaling pathways
- Support cellular stress response mechanisms
- Support metabolic markers in certain populations
Evidence strength varies depending on the condition and study design. Hydrogen water is best considered a supportive wellness tool, not a medical treatment.
How does molecular hydrogen work?
How does molecular hydrogen work?
Hydrogen (H₂) is a small, neutral molecule that diffuses rapidly through tissues.
Scientific literature proposes that hydrogen may:
- Influence oxidative stress pathways
- Activate endogenous antioxidant systems
- Modulate inflammatory signaling networks
- Influence mitochondrial function and cellular signaling
Its effects are thought to occur through signaling modulation rather than accumulation in the body.
When was hydrogen’s therapeutic benefit discovered?
When was hydrogen’s therapeutic benefit discovered?
Modern research interest accelerated after a 2007 peer-reviewed publication describing hydrogen as a selective antioxidant. Since then, thousands of studies have explored its biological effects.
How long does hydrogen stay in water?
How long does hydrogen stay in water?
Dissolved hydrogen gradually escapes from water.
To preserve concentration:
- Drink within 10–15 minutes of generation, or
- Keep sealed until consumption
Like carbonation, hydrogen does not disappear instantly but declines over time.
How much hydrogen water should I drink per day?
How much hydrogen water should I drink per day?
There is no universally agreed dose.
Many studies use:
- 0.5–1.6 ppm hydrogen concentration
- Several hundred milliliters to ~1–2 liters per day
Consistency over weeks appears more important than very high single-day intake.
Can you overdose on hydrogen water?
Can you overdose on hydrogen water?
Hydrogen does not accumulate in the body and is exhaled.
There is no known toxic oral dose at levels studied in humans.
The main risk would be excessive water consumption (hyponatremia), not hydrogen itself.
Is hydrogen water safe?
Is hydrogen water safe?
Published human studies report a favorable safety profile at studied intake levels.
Hydrogen is not stored in tissues and is eliminated through breathing.
Individuals with kidney disease or fluid restrictions should follow medical advice regarding total fluid intake.
Is hydrogen water safe for children?
Is hydrogen water safe for children?
Pediatric-specific data are limited.
Adult safety data suggest low toxicity, but regular use in children — particularly those with chronic illness — should be discussed with a healthcare professional.
Does hydrogen water taste different?
Does hydrogen water taste different?
Hydrogen is colorless, odorless, and tasteless.
Most users report little to no difference in taste compared to regular water.
Does hydrogen water replace medication or supplements?
Does hydrogen water replace medication or supplements?
No.
Hydrogen water is not a replacement for prescribed medication or medically necessary supplements. It is a complementary wellness tool.
Is hydrogen water a hoax or backed by science?
Is hydrogen water a hoax or backed by science?
Hydrogen therapy is supported by a large body of preclinical research and a growing number of human trials.
However, large long-term clinical trials remain limited in many conditions. The most accurate position is: promising and actively researched, but still evolving.
