Izumio - Features

IZUMIO is the No. 1 bestselling product in the hydrogenated water market in Japan. With more than 230 million units distributed since its launch in 2007, IZUMIO is a brand of hydrogenised water product widely consumed by many customers in Japan.

There has been a growing awareness of hydrogenized water in the past few years. In 2017, the cumulative shipping volume of IZUMIO exceeded 230 million units, attesting to its worldwide popularity.

Izumio - Hydrogen Dissolution Ratio

What is “hydrogen dissolution ratio”?

Hydrogen dissolution ratio refers to the concentration of hydrogen dissolved in water.

IZUMIO now gives you more hydrogen than before. With improved filling technology, the hydrogen dissolution ratio of IZUMIO is now among the highest in the industry at 2.6 ppm (parts per million).

Until recently, IZUMIO hydrogenised water was stored temporarily in a filling tank before being filled into aluminium film pouches. But with the implementation of an improved method, by which hydrogenised water is packaged immediately under high pressure without first passing through the filling tank, even the slightest escape of hydrogen gas can be prevented. This new method has made it possible to raise IZUMIO’s hydrogen dissolution ratio even higher. (You are advised to consume IZUMIO as soon as possible after opening the product to minimise the escape of hydrogen gas.)
