All alkaline waters are not created equal. Most people who are familiar with the term “alkaline water” associate it with water that has been put through an ionizer—a machine that uses electricity to split water molecules. This process, called electrolysis, increases water’s pH and thereby makes it artificially alkaline. Unfortunately, artificial alkaline water confers almost no health benefits, does not effectively neutralize acidity and indeed may actually worsen the body’s acid-alkaline balance.

This is because most water that is processed through ionizer machines is basic, run-of-the mill tap water that is sourced from rivers, lakes or wells, and thus lacks the alkaline minerals that are crucial in neutralizing excess acid. It is the mineral content in water, not just its alkaline pH, that the body needs to restore and maintain a healthy balance.
