Composition.

O1 Natural Mineral Water

The origin of O1 Natural Mineral Water lies in the crystalline snowflakes that descend on the towering Karakoram and Himalayan peaks to form one of the world’s largest ice cover outside the polar regions. Over the course of several years, it is filtered through several layers of rocks, gravel, and sand, giving it a unique mineral content and making it as crisp as the mountain air. 


Unparalleled purity & the elixir of life.

Up to 60% of the human adult body is water - that’s why we take water very seriously. We’re very protective of O1’s composition because we’re very aware of the pivotal role water plays in allowing our bodies to function properly.

Our stringent externally audited systems ensure the composition of O1 Natural Mineral Water is remarkably consistent. In addition to being certified by the ISO (International Organisation for Standardisation) for both our quality and environmental management processes, we can attest our bottles' mineral content to the milligram. O1 is untouched from source to bottle.

Unique (and stable) mineral content.

The singular journey of O1 Natural Mineral Water from the towering peaks to the source’s deep aquifer creates its unique mineral content with a mild alkaline composition. O1 is not subjected to any treatment or process that alters the original composition of the water from the source. The composition of minerals is stable, so you know what you’re drinking.

Water as nature intended, fortified with perfect mineral balance. Nothing added, nothing removed.
