H2 Water (Hydrogen Water)
In brief
Section titled “In brief”- H2 water (HRW) is drinking water with extra dissolved hydrogen gas, measured in mg/L or ppm
- Plausible mechanism via modulation of redox and inflammation signals
- Scientific support is preliminary: small studies, varying protocols
- HRW is a supplementary option, not a replacement for lifestyle or treatment
- Try it as a time-limited trial (4-8 weeks) with pre-selected measurement points
- Choose equipment based on H2 concentration and test data, not on ORP claims
1. What is H2 water?
Section titled “1. What is H2 water?”HRW is drinking water with extra dissolved molecular hydrogen gas (H2). The amount is preferably expressed as mg/L (numerically equal to ppm).
Important: Because H2 is volatile, the concentration decreases due to:
- Time
- Heat
- Movement
- Contact with air
Therefore, drink the water immediately after production and don’t leave it open for long.
2. Background and mechanism
Section titled “2. Background and mechanism”HRW is being researched for themes such as metabolic health, exercise, and recovery. The literature is heterogeneous: studies are often small, use varying devices and protocols, and hard clinical endpoints are limited.
Plausible mechanism
Section titled “Plausible mechanism”The presumed effect is mainly based on modulation of redox and inflammation signals, with possible influence on:
- Cellular stress responses
- Mitochondrial function
Mechanism and dose-response are not yet definitively established.
3. Metabolic effects
Section titled “3. Metabolic effects”In studies of cardiometabolic risk factors, favorable shifts in biomarkers are sometimes reported, but generalizability is limited. Practically, HRW is especially interesting when you can follow the effect on metabolic measurement points.
Measurement points you can follow
Section titled “Measurement points you can follow”Depending on your situation:
| Measurement point | Explanation |
|---|---|
| Glucose or HbA1c | Blood sugar regulation |
| Lipid profile | Triglycerides, HDL, LDL |
| Uric acid | Always interpret in context of nutrition, alcohol/fructose, and kidney function |
| Blood pressure | Home measurements |
| Waist circumference and weight | Metabolic markers |
4. When can H2 water be an option?
Section titled “4. When can H2 water be an option?”HRW can be considered when you:
- Are already working on basic factors (nutrition, exercise, sleep, stress)
- Want to try a supplementary option
- Are willing to systematically evaluate the effect
For exercise and recovery, signals of effect have been described, but translation to hard outcomes is uncertain.
5. Safety and points of attention
Section titled “5. Safety and points of attention”HRW is generally well tolerated. Points of attention are usually contextual:
- With fluid restriction (heart failure, advanced kidney disease): the risk is mainly in extra volume intake
- Medication: HRW is not a substitute for medication or monitoring
Assess HRW as a trial with evaluation.
6. Effect evaluation: approach as a trial
Section titled “6. Effect evaluation: approach as a trial”Make it testable with a time-limited trial and pre-selected outcome measures:
Step-by-step plan
Section titled “Step-by-step plan”-
Baseline (1 week)
- Note complaints and measurements
- Energy, sleep, blood pressure
-
Trial duration (4-8 weeks)
- As few other simultaneous changes as possible
- Consistent intake
-
Outcome measures (choose 3-6)
- Energy and fitness
- Recovery after exercise
- Sleep quality
- Blood pressure
- Weight and waist circumference
- Where appropriate: lab values
-
Evaluation
- Stop if there’s no noticeable effect after 6-8 weeks
- Or if use is too burdensome
7. Purchase advice
Section titled “7. Purchase advice”Core principle: choose based on reliability and transparency, not marketing claims.
What to look for?
Section titled “What to look for?”- Measurement of H2 concentration (mg/L or ppm) with clear test conditions
- Water, temperature, time, volume
- Preferably an independent lab report
- Device with clear gas separation technology (e.g., PEM/SPE)
- Clear maintenance instructions
ORP is not a good measure
Section titled “ORP is not a good measure”ORP means oxidation-reduction potential. ORP is not a direct measure of dissolved H2 and is unsuitable for comparing devices.
8. Device examples
Section titled “8. Device examples”Choose a device you can maintain daily. Specifications can vary by model and test conditions.
| Device | H2 concentration | Source |
|---|---|---|
| Echo Go+ | Up to 2.5 ppm (5 min), up to 4.5 ppm (10 min) | Manufacturer documentation |
| Echo Flask | 6.07 mg/L (10 min), 8.25 mg/L (20 min) | Lab report (gas chromatography) |
| Piurify Hydrogenator Bottle | 2.80 mg/L (5 min), 3.85 mg/L (10 min) | H2HUBB test report |
Summary
Section titled “Summary”Veelgestelde vragen
What is H2 water?
H2 water (HRW) is drinking water with extra dissolved molecular hydrogen gas (H2). The concentration is measured in mg/L or ppm. Because H2 is volatile, the concentration decreases over time, with heat, movement, and contact with air.
Does H2 water really work?
The literature shows preliminary signals for themes such as metabolic health and recovery after exercise. However, studies are often small with varying protocols. See HRW as a possible supplement, not a replacement for lifestyle or treatment.
How long should I try H2 water?
Do a time-limited trial of 4 to 8 weeks with pre-selected outcome measures. Measure energy, sleep, blood pressure, or lab values. Stop if there's no noticeable effect after 6 to 8 weeks.
Which H2 generator should I buy?
Choose based on reliability and transparency, not marketing claims. Look for devices with clear H2 concentration measurements (mg/L or ppm) and preferably an independent lab report. Avoid cheap or poorly documented products.
What does ORP mean for hydrogen water?
ORP stands for oxidation-reduction potential. ORP is not a direct measure of dissolved H2 and is unsuitable for comparing devices. Don't let ORP claims guide your purchase.
Is H2 water safe?
HRW is generally well tolerated. With fluid restriction (heart failure, advanced kidney disease), pay attention to the extra volume intake. HRW is not a substitute for medication or monitoring.
