Alkaline Water: What It Is and Why People Like It
Alkaline water is our most popular water. Here's what it is, why people choose it, and what the experts say, in plain language.
What "alkaline" means
pH measures how acidic or alkaline something is, on a scale from 0 to 14. Seven is neutral, and anything above 7 is alkaline. Our alkaline water is pH 9–9.5, and we check it every day.
Why people drink it
The reason we hear most at the counter is simple: people like the taste. Many describe it as smooth and easy to drink. When you enjoy the taste of your water, it's easier to drink enough of it, and staying hydrated matters (see our article on the benefits of drinking water).
What the experts say
Mayo Clinic says that for most people, alkaline water isn't proven to be better than plain water, and that researchers are still studying it. We agree with keeping it simple: alkaline water is a great-tasting way to stay hydrated. We don't claim it cures, treats or prevents any health condition.
Who should check with a doctor first
Mayo Clinic notes that very high pH water (above 9.8) has been linked to high potassium levels, which is a particular concern for people with kidney disease. If you have kidney disease or take medication that affects potassium, talk to your doctor before drinking alkaline water regularly.
Try it for yourself
Alkaline water at our Grantville store is $1.50 a gallon, and you can fill any clean 1 to 5 gallon jug. Not sure which you'll like? Fill a gallon of each and taste them side by side. Here's how alkaline and purified water compare.
