Hydration & molecular hydrogen

What does the science really say about hydration?

There is a lot of information about water, hydration, minerals, alkalinity and hydrogen. Some claims are well supported, some are still being researched and others are often misunderstood. This page will help you separate them.

Written for anyone who has been told a great deal about water and would like to know which parts of it hold up.

How this works

A simpler way to understand your options.

Four simple steps to help you understand the evidence, explore the options and decide what makes sense for you.

01

Discover

See what different approaches to hydration actually do.

02

Understand

Learn where the evidence is strong and where questions remain.

03

Explore

Compare habits, water quality and hydration technologies.

04

Choose

Decide what makes sense for you.

02 · Why it matters

Hydration is about more than simply drinking more water.

Water is not a nutrient you top up in isolation. It is the medium every other process runs in. Blood volume, temperature regulation, joint lubrication, the transport of nutrients and the removal of waste through the kidneys all depend on fluid balance. This part is not contested. It is ordinary physiology, taught in every medical school.

Two practical consequences follow. Thirst arrives after a deficit has already started, so it is a lagging signal rather than an early one. And because the effects are systemic rather than local, mild shortfalls tend to show up as something vague, tiredness, a headache, poorer concentration, rather than as thirst.

03 · What the evidence says

Not every hydration claim is backed by the same level of evidence.

Established

Everyday hydration

Strong evidence supports the importance of adequate fluid intake for normal body function.

Early

Molecular hydrogen

An emerging area of research with a growing body of published studies.

Often overstated

Alkalinity and blood pH

Your body tightly regulates blood pH. Drinking alkaline water should not be presented as a way of changing blood pH.

Do you think all water is the same?

04 · The options

Three areas worth paying attention to.

Daily habits

How much you drink, what you eat, activity, climate and lifestyle all influence hydration.

Water quality

What is in your water can vary considerably depending on source, treatment and location.

Hydrogen technology

Some water technologies are designed to produce dissolved molecular hydrogen, an area now being studied for potential biological effects.

Not all water technologies do the same job.

Water treatment can involve very different processes and understanding the difference matters.

Filtration
Designed to reduce specific contaminants or unwanted substances from water. The effectiveness depends on the filter media used and what it has actually been tested to remove.

Reverse Osmosis
Uses a membrane to remove a very wide range of dissolved substances from water. In doing so, it can also remove naturally occurring minerals. Some systems therefore include a remineralisation stage.

Water Ionisation
Uses electrolysis to produce waters with different properties and applications. The quality of the technology, internal materials and source water all matter.

Molecular Hydrogen Technology
Designed to produce dissolved molecular hydrogen in water. How that hydrogen is generated, the materials involved and the engineering of the system can vary significantly between technologies.

The important question is not simply, "What type of water is this?" It is, "What is the technology actually doing to the water?

05 · The limits

Not all water ionisers and molecular hydrogen technologies are the same.

The technology used to produce molecular hydrogen matters.

Different systems use different internal components, materials and methods and they are not all manufactured to the same standard. Understanding how molecular hydrogen is produced, what materials come into contact with the water and how the technology has been designed is an important part of making an informed decision.

This is one of the areas we help people understand.
