About Hydrogen & Hydrogen Therapy
Hydrogen water—also called hydrogen‑rich water—is plain H₂O that contains dissolved molecular hydrogen gas (H₂). Just as carbonated beverages contain dissolved CO₂ and oxygen water contains O₂, hydrogen water contains free H₂ molecules. This dissolved H₂ is being studied for antioxidant and cell‑signaling benefits.
Doesn’t water already have hydrogen in it because water isH₂O?
Water (H₂O) contains hydrogen atoms that are chemically bound to oxygen and therefore not available as free hydrogen gas. Free H₂ means two hydrogen atoms bonded together in their gaseous state—the form studied for potential health benefits—so it must be infused separately.
Is hydrogen water similar to alkaline water?
Hydrogen infusion does not alter the pH of your source water. If you prefer alkaline water, you can hydrogenate alkaline water, but hydrogen water’s benefits relate to dissolved H₂, not alkalinity.
What are the benefits of molecular hydrogen therapy?
Research suggests molecular hydrogen may help reduce oxidative stress and inflammation and support healthy cell signaling—areas linked to recovery, metabolic health, neurological wellness, and overall vitality.
When was hydrogen’s therapeutic benefit first discovered?
Early observations date to the 18th century. In 1975, Baylor College of Medicine explored hyperbaric hydrogen in tumor‑bearing mice. The field accelerated in 2007 with Dr. Shigeo Ohta’s Nature Medicine paper describing hydrogen as a selective antioxidant. Since then, 2,000+ peer‑reviewed papers have been published.
Will dissolved hydrogen gas immediately escape from the water?
Like carbonation, dissolved H₂ gradually escapes but not instantly. Consume within 10–15 minutes, or place in a sealed stainless‑steel container to slow the loss (can last a few hours).
Is Molecular Hydrogen safe for kids?
Molecular hydrogen is generally considered safe when used appropriately for different age groups. Please consult your clinician for personal situations. For practical tips, see our blog “Is Molecular Hydrogen Safe for Kids?”.
Can I drink hydrogen water instead of taking medication orsupplements?
Hydrogen therapy is a supportive wellness tool and must not replace medications or essential supplements. Always follow your clinician’s advice for diagnosis and treatment.
When will I notice effects from hydrogen water?
Immediate changes may include better hydration or energy. Benefits related to oxidative stress often require weeks or months of consistent use—similar to vitamins where effects accumulate over time.
Is it possible to overdose on hydrogen‑rich water?
Hydrogen does not build up to toxic levels. Unused H₂ is released through breath and urine, so large intakes are generally considered safe.
How much hydrogen water should I drink daily?
Many users aim for 1–3 liters per day. If you are new to hydrogen water, begin with one bottle and increase to ~1.5 L (around four H Fizz bottles) over 1–2 weeks, adjusting if mild digestive discomfort occurs.
Safety & Scientific Backing
What mainstream research supports hydrogen therapy?
Hydrogen therapy has been explored in 2,000+ peer‑reviewed publications, including journals such as Nature Medicine and Scientific Reports, describing antioxidant, anti‑inflammatory, and
cell‑signaling effects. See the Molecular Hydrogen Institute and hydrogen studies databases for curated lists.
Is hydrogen safe to inhale?
Hydrogen gas is non‑toxic and
non‑allergenic; the gut also produces small amounts naturally. Clinical trials and decades of practice indicate that recommended personal‑use flow rates are safe. It has also been used safely in hospitals and deep‑sea diving applications.
How much H₂ should I inhale for effectiveness?
Most studies use 1–3 liters per minute for 30–60 minutes daily. Home devices deliver lower flows but may still be beneficial when used consistently. H Fizz Lite: 150 mL/min; H Fizz Complete: 300 mL/min.
If it’s effective, why haven’t I heard of it?
Hydrogen therapy has been used for over a decade in Japan, Korea, and China (including hospitals and wellness clinics). As a natural, non‑patentable molecule, it receives less pharmaceutical promotion in the West—but awareness is growing via research and media.
Products & Comparisons
Where are your products made?
H Fizz products are manufactured in mainland China by leading hydrogen therapy equipment makers with CE/ISO certifications and rigorous quality control at the factory and before delivery to Hong Kong customers.
Why are your products affordable?
We work directly with manufacturers, cut out middlemen, and keep advertising overhead low. This lets us pass savings to customers while meeting or exceeding safety and performance standards.
Classic vs. Plus hydrogen bottles
Classic produces about 1.2–1.6 ppm dissolved H₂ for daily hydration. Plus reaches higher concentrations, runs faster cycles, and includes a larger battery. Both use SPE/PEM membranes to infuse pure H₂ without ozone or chlorine.
Lite vs. Complete machines
H Fizz Lite outputs 150 mL/min. H Fizz Complete outputs 300 mL/min and has dual outlets for inhalation and water infusion—ideal for stronger, faster sessions. Both are CE‑certified with advanced SPE/PEM membranes.
Usage & Maintenance
How do the bottles work?
All H Fizz bottles use SPE/PEM electrolysis to split H₂O and infuse only pure H₂ into the water; oxygen by‑product is vented away for purity.
What type of watershould I use?
For best performance and membrane longevity, use distilled, purified, or mineral water. Do not use juices, tea, milk, or other beverages as they may damage the electrolysis plate.
Can I use hot or cold water?
Use room‑temperature, cool, or warm water up to 60°C. Do not pour boiling water, which can damage the PEM membrane and may void the warranty.
Cleaning instructions
Daily: rinse glass and lid with mild detergent and dry; wipe the base—do not submerge. Weekly: descale with warm water + vinegar or citric acid. Keep generator water <95°C. For long storage, keep the electrolysis plate damp with distilled water.
What is the ozone water function?
The bottle’s ozone water mode generates O₃ water for routine cleaning, helping reduce scale and sanitize the bottle. Activate by long‑pressing the power button for a 5‑minute cycle. Do not drink the ozone water.
Common issues &solutions
If no bubbles appear, prime the PEM by soaking with warm water for 8–24 hours. If leaking, check that the glass and base are tightly screwed; vent pressure between cycles. Low bubbles are normal at first—run several cycles or use warm water. Residual water on arrival is normal—plates are pre‑moistened to protect the membrane.
Battery & charging
Charge for 3–4 hours using the supplied 5V/1A USB cable to power ~8–10 cycles (varies by water quality). Indicator lights: Blue = hydrogenating; Red = charging; Green = full; Blinking red during a cycle = low battery.
Delivery & shipping

Warranty claims
To file a claim, email or WhatsApp your name, order number, issue description, and photos/videos. Approvals typically take 3–5 days; replacement units usuallyship within ~2 days after approval.
Does hydrogen water taste different?
Molecular hydrogen is colorless, tasteless, and odorless, so most users report no significant taste difference. A minority notice a subtle mouthfeel difference similar to flat vs. lightly sparkling water.
