The pH of Hint is between 3.5 and 4, which is at least 10 times LESS acidic than a typical soda. Many people who ask us about pH have been told that they should only drink pH 7 or higher beverages. this is not the case. The acidity of Hint is insignificant relative to the acidity found in the stomach, for example, and will have no impact on the pH of your body.
Unlike sports drinks and sodas, Hint's pH is easily neutralized because it does not have a strong buffer system. The buffers in many "sports" drinks can significantly delay the mouth's ability to eliminate excess acidity on dental surfaces.
