Is Hydrogen Water Worth It?
The evidence for hydrogen water benefits is preliminary and does not justify the high cost.
Hydrogen water is regular water with dissolved molecular hydrogen (H2) gas added. Proponents claim it has antioxidant, anti-inflammatory, and energy-boosting properties. While some early research in animals and small human studies shows potential, the evidence is far from conclusive. Hydrogen water products are significantly more expensive than regular water, often costing $3-10 per bottle or $100+ for generators. For most people, the potential benefits do not justify the cost when compared to simply drinking adequate regular water.
Hydrogen Water Claims vs Evidence
Antioxidant Claims
Some studies show H2 may act as a selective antioxidant. However, most studies are small, short-term, or conducted in animals. No large-scale human trials confirm significant antioxidant benefits.
Athletic Performance
A few small studies suggest hydrogen water may reduce exercise-related fatigue and lactate buildup. Results are inconsistent and the effects are modest at best.
Anti-Inflammatory Effects
Animal studies show some anti-inflammatory potential. Human evidence is limited to small studies with mixed results. More research is needed before claims can be validated.
Cost vs Benefit
At $3-10 per bottle, hydrogen water is 100-500x more expensive than tap water. The unproven benefits make it a poor value compared to simply drinking adequate regular water.
Practical Recommendations
- Hydrogen water is safe to drink but there is insufficient evidence to recommend it over regular water
- Save your money and focus on drinking adequate regular water instead
- If you want antioxidants, eat fruits and vegetables which provide proven benefits
- Be skeptical of marketing claims that are not backed by large-scale human clinical trials
- The most important factor for hydration is drinking enough water, regardless of type

Frequently Asked Questions
Is hydrogen water safe?
Yes, hydrogen water is safe to drink. The FDA recognizes dissolved hydrogen as GRAS (generally recognized as safe). There are no known side effects from drinking hydrogen water.
How is hydrogen water made?
Hydrogen gas is dissolved into water under pressure, either during manufacturing or via home hydrogen generators. Some products use magnesium tablets that react with water to produce hydrogen.
Does hydrogen water taste different?
Most people cannot taste a difference between hydrogen water and regular water. Some report a slightly smoother or softer taste, but this is subjective.
How long does hydrogen stay in the water?
Dissolved hydrogen begins escaping once the container is opened. Hydrogen water should be consumed quickly after opening for maximum hydrogen content.
Are hydrogen water generators worth buying?
At $100-500, generators are expensive. Given the limited evidence for benefits, they are not recommended for most consumers. Regular water or a quality filter is a better investment.
