Bubbles O2 is a natural mineral water rich with dissolved oxygen drawn from an underground river 800 feet below the surface in the state of Negeri Sembilan, Malaysia. The source of the aquifer is located deep within the peninsula’s Central Mountain Range. The water is supersaturated naturally with oxygen after its years-long journey through weathered rock, resulting in pure oxygen-rich, crystal-clear water which bubbles upon surfacing and is then directly bottled at the source.
