Alkaline water refers to water with a higher pH level than regular drinking water. While tap water typically has a neutral pH of around 7, alkaline water has a pH level of 8 or 9. Proponents of alkaline water believe that it can neutralize acid in the body, providing health benefits such as improved hydration, detoxification, and even disease prevention. Ionized water, a type of alkaline water, is produced through a process called electrolysis. During electrolysis, water is split into two streams—acidic and alkaline—using an ionizer machine. The ionized water is then consumed for its supposed health benefits.
