evidence: Take a walk down the drink aisle at your local grocery store and you’ll probably be surprised by the number of different types of bottled water you see. They all advertise something different, from spring water to vitamin-enriched and everything in between. You may also notice some bottles that mention the pH level in the water and how that may benefit your health. [...] The pH of your water should only matter if it’s caustic enough to hurt you. Most commercial uncontaminated bottled water won’t make you healthier or sick due to its pH. Depending on the source and processing, most bottled water stays between a pH of 5 to 8. [...] A few bottled water brands run almost toward a pH of 8, but slightly more alkaline water doesn’t mean you’ll get additional health benefits. There isn’t any solid scientific evidence that says eating more alkaline foods or drinking alkaline water helps keep a person more disease-free than someone who doesn’t.
