Patented Hydrogen Infusion Technology
IZUMIO uses a patented hydrogen infusion process to achieve high hydrogen concentration and stability, delivering 3.3 ppm of dissolved hydrogen at production while refining the water through an advanced degassing process.
Quality Water Matters
IZUMIO is crafted from artesian well water drawn from Tochigi, Japan. Its naturally low REDOX potential (−570 to −700 mV) reflects a strong antioxidant environment—showing that water quality matters from the very start.
Hydrogen Retention Packaging
IZUMIO’s four-layer aluminum pouch helps minimize hydrogen loss. The patented upside-down packaging plays a key role in hydrogen retention. Pre-pouched for grab-and-go convenience—no preparation.
Continuing Legacy of Trust
Since its launch in 2007, IZUMIO has stood as Japan’s longest-running and most trusted hydrogenized water brand, serving as the global benchmark for excellence.
Scientifically Endorsed
Grounded in hydrogen research and endorsed by leading experts, including Nobel Prize nominee Prof. Emeritus Garth L. Nicolson, for its technical precision and proven innovation.
