Hydrogen Water vs. Regular Water: Is There a Difference?

In recent years, hydrogen water has sparked interest among health enthusiasts, touted for its potential benefits over regular drinking water. This article explores the intriguing concept of hydrogen water, comparing it to the traditional H2O we rely on for daily hydration.

What is Hydrogen Water?

Hydrogen water is essentially regular water (H2O) infused with additional hydrogen gas (H2), creating a beverage with a higher concentration of hydrogen than standard water. Methods such as electrolysis are commonly used to dissolve hydrogen gas into water, with proponents claiming that this process endows the water with various health benefits.

Potential Benefits of Hydrogen Water

The potential benefits of hydrogen water are rooted in its enhanced content of hydrogen molecules. Here's a deeper look into how these supposed benefits work:

Anti-inflammatory Properties

  • Mechanism: The additional hydrogen in hydrogen water is thought to have the capability to act as a selective antioxidant. This means it can target and neutralize specific harmful radicals in the body, particularly the reactive oxygen species (ROS) that contribute to inflammation.

  • Implications: By reducing the levels of ROS, hydrogen water could potentially diminish inflammation in the body. This is important because autoimmune disorders, cancer, heart disease, and other diseases are associated with chronic inflammation.

Antioxidant Properties

  • Mechanism: Antioxidants can stop or lessen the damage that free radicals, unstable chemicals created as a result of regular cell activity, and environmental factors like pollution do to cells. Hydrogen, a small and highly diffusible molecule, can easily penetrate cells and tissues where it can exert its antioxidant effects.

  • Implications: The antioxidant effect of hydrogen water could help protect cells from oxidative stress, a condition characterized by an excessive amount of free radicals that can lead to cell damage, aging, and various health issues.

Oxidative Stress Reduction

  • Explanation: Oxidative stress is the result of an imbalance between the body's generation of free radicals and its antioxidant capacity to neutralize their damaging effects. Hydrogen water's purported ability to act as an antioxidant could help restore this balance, reducing oxidative stress.

  • Potential Health Benefits: Lowering oxidative stress may contribute to reduced risk of chronic diseases, improved longevity, and better overall health. Conditions like neurodegenerative diseases (e.g., Alzheimer's and Parkinson's disease), diabetes, and cardiovascular diseases have been linked to oxidative stress.

Need for More Research

  • While some studies support the idea that hydrogen water can offer these health benefits, the evidence is not yet robust. Many of the studies are preliminary, conducted in vitro (in test tubes) or in animal models, with fewer studies in humans.

  • The exact mechanisms through which hydrogen exerts these effects, the optimal amount of hydrogen water for health benefits, and the long-term impacts of consuming hydrogen water require further scientific exploration.

Regular Water: The Basis of Hydration

Regular water remains the fundamental source of hydration, vital for numerous bodily functions and overall health. It's generally considered sufficient for maintaining hydration, with no added elements necessary for its health-supporting role.

Hydrogen Water vs. Regular Water: The Differences

The main difference between hydrogen water and regular water is, as mentioned, the added hydrogen gas (H2) in hydrogen water. Let's delve deeper into what this means and its implications:

Hydrogen Water

  • Composition: Hydrogen water contains dissolved hydrogen gas. This doesn't change water's H2O structure; instead, molecular hydrogen is added to the water in its gaseous form (H2), increasing its concentration.

  • How It's Made: Usually, electrolysis is used to do this, in which water is divided into hydrogen gas and oxygen by an electric current, with the hydrogen then being dissolved back into the water.

  • Proposed Benefits: The added H2 is believed to act as an antioxidant, selectively neutralizing harmful free radicals in the body. Proponents argue this can reduce oxidative stress, inflammation, and associated health risks.

Regular Water

  • Composition: Regular water, whether tap, bottled, or filtered, consists of two hydrogen atoms bonded to one oxygen atom (H2O). It does not contain additional hydrogen gas.

  • Health Benefits: Essential for life, regular water aids in hydration, digestion, nutrient absorption, and detoxification, among other vital bodily functions. It's universally acknowledged as crucial for maintaining health.

The Debate on Health Benefits

  • Scientific Scrutiny: While adding hydrogen to water for health benefits is intriguing, the scientific community continues to examine whether these benefits are significantly greater than those of regular water. The key questions are whether the concentration of dissolved hydrogen in hydrogen water can have a measurable impact on health and whether these effects are sustained over time and in varying conditions.

  • Antioxidant Properties: The idea that hydrogen water serves as a potent antioxidant is central to its purported health benefits. However, the human body already has complex antioxidant systems in place. Researchers are investigating how supplemental antioxidants from hydrogen water might interact with these systems and whether they provide added value.

  • Clinical Evidence: Some studies have suggested potential benefits, such as improved athletic performance, reduced markers of inflammation, and enhanced metabolic health. Yet, many of these studies are small-scale, short-term, or have been conducted primarily on animals. Comprehensive, long-term clinical trials on humans are necessary to substantiate these claims.

Cost Consideration and Accessibility

Hydrogen water often comes at a higher price than regular tap or bottled water, making it less accessible for everyday consumption. The cost factor is a significant consideration for those pondering its regular inclusion in their hydration routine.

Skepticism and Criticisms

There's a fair amount of skepticism regarding the marketed benefits of hydrogen water, with critics pointing to the lack of definitive scientific evidence and suggesting that the placebo effect may influence the observed benefits. Additionally, consumer testimonials, while compelling, cannot substitute for rigorous scientific validation.

Who Might Benefit from Hydrogen Water?

Though the jury is still out on the broad benefits of hydrogen water, some research suggests specific populations or individuals with certain conditions might experience health improvements from its consumption. Nevertheless, it should be viewed as a supplementary hydration option rather than a replacement for regular water.


While hydrogen water presents an interesting addition to the myriad of hydration options available, its benefits over regular water are not conclusively proven. While potentially beneficial for some, the differences may not justify the cost and accessibility hurdles for the average consumer. 

As part of a balanced diet and hydration strategy, regular water remains an essential, universally accessible, and cost-effective choice. Exploring the benefits of hydrogen water is ongoing, and future research may shed more light on its role in health and hydration.
