Walk through any grocery store beverage aisle, and you’ll likely spot sleek bottles of water boasting “high pH” or “alkaline” benefits. These claims promise everything from better hydration to improved energy and even disease prevention. But what do these terms actually mean—and is alkaline water really better for you, or is it just clever marketing?
Understanding pH and Alkalinity
pH is a scale that measures how acidic or basic (alkaline) a substance is, ranging from 0 (very acidic) to 14 (very alkaline), with 7 being neutral. Pure water sits around 7. Alkaline water usually has a pH between 8 and 10, achieved either naturally (via mineral content) or artificially through ionization.
Marketers claim that drinking water with a higher pH can help "neutralize" acid in your body, improve metabolism, and even slow aging. The idea stems from studies that suggest reducing acid-forming foods and drinks can support overall health.
What Science Says
Overall, there is limited scientific evidence to suggest any benefits. While it’s true that the pH of water can be altered, your body is already excellent at maintaining its acid-base balance, primarily through your lungs and kidneys. Drinking slightly alkaline water isn't harmful for most people.
Some small studies suggest that alkaline water may help reduce acid reflux or improve bone strength, but more results are needed for this to be conclusive. For most people, drinking clean, well-regulated tap or bottled water, regardless of pH, is perfectly sufficient.
The Takeaway
While the concept of alkaline water might sound appealing, most experts would agree it is a marketing-driven trend rather than a medical necessity. Unless you have a specific condition that might benefit from altered pH levels (and your doctor agrees), the most important thing is simply staying hydrated, whether your water is alkaline or not.
