Hydrogen Water: The Complete Guide

Everything you need to know about molecular hydrogen water, what the research says, how it compares to alkaline water, and where to buy it in South Africa.

What Is Hydrogen Water?

Hydrogen water is drinking water that contains dissolved molecular hydrogen (H2) gas. Molecular hydrogen is the smallest and lightest molecule in existence, consisting of just two hydrogen atoms bonded together.

Regular water is H2O. Hydrogen water is H2O with additional H2 molecules dissolved into it, similar to how carbon dioxide is dissolved into sparkling water. The hydrogen does not change the water's chemical formula. It remains water with extra molecular hydrogen in solution.

The concept is straightforward: take high-quality water and infuse it with molecular hydrogen during the production process. The result is water that looks, pours, and hydrates like any other water, but contains dissolved H2 gas that would not normally be present in standard drinking water.

Key fact: Molecular hydrogen (H2) is the smallest molecule in existence. It is colourless, odourless, and tasteless. When infused into water during bottling, it dissolves into solution without altering the water's appearance or basic properties.

What Does ORP Mean?

You will often see ORP mentioned alongside hydrogen water. ORP stands for Oxidation-Reduction Potential, measured in millivolts (mV). It indicates the water's electrochemical potential.

Standard tap water typically has a positive ORP value, while hydrogen-rich water tends to have a reduced (lower) ORP. Designer Water has a reduced ORP at the time of bottling, which is a measurable characteristic of the molecular hydrogen infusion process.

How Molecular Hydrogen Is Infused Into Water

There are several methods used to produce hydrogen water:

Industrial Infusion (Bottled Hydrogen Water)

Professional bottling facilities use specialised equipment to dissolve molecular hydrogen gas directly into purified water under controlled conditions. This is the method used in commercial hydrogen water production, including at Designer Water's SANBWA-accredited facility in Midrand, South Africa. The infusion occurs at the time of bottling, and the water is sealed immediately to retain the dissolved hydrogen.

Electrolysis Machines

Hydrogen water machines (also called ionisers) use electrolysis to split water molecules, generating hydrogen gas at the cathode. Some dissolved hydrogen remains in the water that flows from the machine. These devices vary widely in quality and hydrogen output.

Hydrogen Tablets

Magnesium-based tablets react with water to produce molecular hydrogen gas. These are portable but produce variable concentrations and often leave a metallic taste.

Designer Water's approach: Molecular hydrogen infusion at the time of bottling. This is a controlled, industrial process at our ISO 22000-certified facility, ensuring consistency across every bottle produced.

Hydrogen Water vs Alkaline Water

These terms are related but describe different things. Understanding the distinction matters if you are comparing products.

FeatureHydrogen WaterAlkaline WaterDesigner Water pH10
DefinitionWater with dissolved H2 gasWater with pH above 7Both: alkaline pH 10 + H2 infusion
pH LevelCan be any pHTypically 8-10+10+
Molecular HydrogenYes (dissolved H2)Not necessarilyYes, infused at time of bottling
MineralsVariesCa, Mg, K typically addedCalcium, Magnesium, Potassium
ORPTypically reducedVariesReduced ORP at time of bottling
ProcessH2 gas infusionMineralisation/ionisation14-stage purification + mineralisation + H2 infusion

Most alkaline water brands focus only on pH. Most hydrogen water products focus only on dissolved H2. Designer Water pH10 combines both: alkaline mineralisation to pH 10+ with molecular hydrogen infusion at the time of bottling, plus a reduced ORP at the time of bottling.

This is not a common combination in the South African market. Most bottled water companies offer one or the other, not both.

What the Research Says

Molecular hydrogen has become one of the most actively researched molecules in the scientific community. The numbers are notable:

  • Over 1,000 peer-reviewed scientific publications on molecular hydrogen
  • Research conducted across 170+ disease models in cell and animal studies
  • Over 100 human clinical trials published or in progress
  • Studies published in journals including Nature Medicine, Free Radical Research, and Medical Gas Research

The first landmark study was published in Nature Medicine in 2007 by Ohsawa et al., which generated significant interest in molecular hydrogen research. Since then, the field has expanded rapidly, with researchers across Japan, China, Korea, the United States, and Europe publishing findings.

Important note: Designer Water presents this research information for educational purposes only. We describe our production process factually: molecular hydrogen infusion at the time of bottling, and reduced ORP at the time of bottling. These are process descriptions, not health claims. We encourage consumers to review the published research independently.

Key Research Areas

Published scientific studies on molecular hydrogen cover a wide range of research areas. The Molecular Hydrogen Institute (MHI) maintains a comprehensive database of these publications. Research topics include:

  • Exercise performance and recovery (human clinical trials)
  • Metabolic parameters (human clinical trials)
  • Cognitive function research (animal and cell studies)
  • Gut microbiome interactions (emerging research)
  • Athletic hydration studies (human trials)

The volume of published research is substantial and growing. Between 2007 and 2025, the annual number of published papers on molecular hydrogen increased significantly each year. This is an active field of scientific investigation, not a fringe topic.

Research Resources

For those who want to explore the published research:

  • Molecular Hydrogen Institute (MHI) — maintains the largest database of H2 research, with categorised studies and summaries
  • PubMed — search "molecular hydrogen" for peer-reviewed publications
  • Medical Gas Research — a dedicated journal covering hydrogen and other therapeutic gases

Hydrogen Water in South Africa

The South African hydrogen water market is still developing. While hydrogen water has been established in Japan and Korea for over a decade, South African consumers are only now becoming aware of it. Search interest for "hydrogen water" in South Africa has grown steadily, with approximately 800 searches per month for the term.

Currently, options for hydrogen water in South Africa are limited:

  • Imported hydrogen water — expensive due to shipping and import duties, with uncertain hydrogen retention during transit
  • Hydrogen water machines — available from R3,000 to R15,000+, with variable quality and maintenance requirements
  • Hydrogen tablets — available online, but inconsistent concentration and taste
  • Locally produced hydrogen-infused water — Designer Water is among the few South African producers offering molecular hydrogen infusion at the time of bottling

For South African consumers looking for hydrogen water, locally produced options offer several advantages: fresher product (shorter time from bottling to consumption), no import markups, and accountability to local regulatory standards including SANBWA accreditation.

Designer Water's Molecular Hydrogen Infusion Process

Designer Water produces premium alkaline water at its facility in Midrand, Gauteng. The production process combines multi-stage purification, alkaline mineralisation, and molecular hydrogen infusion.

The 14-Stage Process

  1. Source water intake and pre-filtration
  2. Sediment removal (5 micron)
  3. Activated carbon filtration (chlorine and organics removal)
  4. Fine sediment filtration (1 micron)
  5. Reverse osmosis purification
  6. Post-RO polishing
  7. Mineral injection (Calcium, Magnesium, Potassium)
  8. pH adjustment to 10+
  9. Molecular hydrogen infusion
  10. UV sterilisation
  11. Ozone treatment
  12. Final quality control testing
  13. Bottling and sealing
  14. Batch testing and release

The molecular hydrogen infusion occurs at step 9, after mineralisation and pH adjustment but before final sterilisation and bottling. This sequencing is deliberate: the water is already purified and mineralised before H2 is introduced, and it is sealed immediately after infusion to retain the dissolved hydrogen.
