Structured Water —
what are micro-clusters
and how they hydrate cells

We have been drinking water forever — but did you know that the structure of water molecules determines how effectively you hydrate your cells? Discover why regular water hydrates at only 15%, while Kangen Water hydrates at 95%.

What is structured water?

Electrolysis is a physical process — not a chemical one. No substances are added to the water. It is an electric current flowing through water via specially designed titanium-platinum plates that reorganizes the water molecules.

The problem with regular water — tap or bottled — is that the clusters are too large. Regular water forms clusters of 15 to 26 molecules. Cell membranes have pores of a specific size — and these large clusters simply cannot pass through them.

Water clusters — what they are and why they matter

Electrolysis is a physical process — not a chemical one. No substances are added to the water. It is an electric current flowing through water via specially designed titanium-platinum plates that reorganizes the water molecules.

The problem with regular water — tap or bottled — is that the clusters are too large. Regular water forms clusters of 15 to 26 molecules. Cell membranes have pores of a specific size — and these large clusters simply cannot pass through them.

Kangen Water, through the electrolytic process, breaks these large clusters down into smaller micro-clusters of just 5 to 8 molecules. These smaller groups pass freely through cell membranes, hydrating cells directly and effectively.

Cellular Hydration Efficiency

Comparison of how much water actually reaches the cells of the body.

Ordinary water (tap / bottled) 15%
Large clusters (15–26 molecules) — they penetrate cell membranes poorly
Kangen water (micro-clusters of 5–8 molecules) 95%
Micro-clusters freely pass through aquaporins — protein water channels in the cell membrane

Benefits of Cellular Hydration

When cells are truly hydrated — not just surrounded by water, but filled with it from the inside — the body functions better on many levels.

Frequently Asked Questions

Structured water — what is it, a short explanation?
Structured water is water whose H₂O molecules form smaller, more regular clusters than in ordinary water. Thanks to the smaller clusters (5–8 molecules vs 15–26 in ordinary water), it passes more easily through cell membranes, hydrating cells much more effectively. Kangen water is structured water — electrolysis changes the cluster structure.
Can the micro-clusters of Kangen water be measured scientifically?
Yes. The size of water clusters can be measured by NMR (nuclear magnetic resonance spectroscopy). Studies using this technique have shown that Kangen water forms clusters of significantly smaller size than ordinary tap or bottled water. It's a physical measurement — not a marketing claim.
How long does Kangen water retain its micro-cluster structure?
The micro-cluster structure gradually fades after the water is drawn — the clusters return to normal size over time. It's best to drink Kangen water freshly drawn or stored in a tightly sealed glass or stainless steel bottle, within 24–48 hours at most. Stored in the fridge, it keeps its properties longer.
How does structured water differ from mineral water?
Mineral water is valued for its mineral content. Structured Kangen water contains minerals (they aren't removed during electrolytic filtration), but additionally has smaller molecule clusters and a negative ORP (antioxidant properties). Bottled mineral water usually has a positive ORP and a standard cluster structure. Kangen combines minerals with the properties of structured water.
Cellular hydration — how long to wait for results?
The first effects — more energy, better well-being, less fatigue — many people feel within 2–4 weeks of drinking Kangen water regularly. Visible changes in skin appearance usually appear after 4–8 weeks. The full, long-term effects of cellular hydration are seen after several months of consistent use.
Are the properties of structured water scientifically confirmed?
The properties of alkaline ionized water (including the altered cluster structure) have been the subject of scientific research for several decades, especially in Japan and Korea. Studies in the PubMed database confirm various properties of ionized water, including antioxidant properties. The electrolytic technology itself is approved by the Japanese Ministry of Health as a medical device.
