When you drink TEN, you experience water like no other. Many bottled waters can be acidic, but TEN is no ordinary water because it has been infused with a patented formulation of minerals for an optimal pH level of 10. With essential alkaline minerals including potassium and sodium ions, TEN water is rich with electrolytes, resulting in a higher pH, just like water found in the purest glaciers. TEN spring water is sourced from natural springs, filtered through at least 100 feet of fractured quartzite. Then traveling underground direct to a state-of-the-art bottling facility, this pristine water never reaches the surface until it's bottled and capped. When testing the pH of TEN please use a calibrated electronic meter.
