H2 Water (Hydrogen Water)

  • 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

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.

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.

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.

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.

Depending on your situation:

Measurement pointExplanation
Glucose or HbA1cBlood sugar regulation
Lipid profileTriglycerides, HDL, LDL
Uric acidAlways interpret in context of nutrition, alcohol/fructose, and kidney function
Blood pressureHome measurements
Waist circumference and weightMetabolic markers

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.

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.

Make it testable with a time-limited trial and pre-selected outcome measures:

  1. Baseline (1 week)

    • Note complaints and measurements
    • Energy, sleep, blood pressure
  2. Trial duration (4-8 weeks)

    • As few other simultaneous changes as possible
    • Consistent intake
  3. Outcome measures (choose 3-6)

    • Energy and fitness
    • Recovery after exercise
    • Sleep quality
    • Blood pressure
    • Weight and waist circumference
    • Where appropriate: lab values
  4. Evaluation

    • Stop if there’s no noticeable effect after 6-8 weeks
    • Or if use is too burdensome

Core principle: choose based on reliability and transparency, not marketing claims.

  • 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 means oxidation-reduction potential. ORP is not a direct measure of dissolved H2 and is unsuitable for comparing devices.

Choose a device you can maintain daily. Specifications can vary by model and test conditions.

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.
