pH is a measure of how acidic/basic (alkaline) water is. The range spans 0 - 14, where 7 is neutral. pHs of less than 7 indicate acidity, where a pHs of greater than 7 indicate alkalinity.
At the acidic end of the spectrum you would find fizzy, sugary soft drinks, fast food and alcohol. With its pH of 9+, Actiph provides a refreshing alkaline alternative to our increasingly acidic diets.
