Is It Safe? Unless you have a kidney disease, alkaline water doesn't pose any serious health risks. The high pH could make your skin dry and itchy or cause an upset stomach, but that's about all. Just because it's safe, though, doesn't mean it does anything for you.

Researchers find that levels are too low to offer benefit "While alkaline water products have a higher pH than regular water, they have a negligible alkali content, which suggests that they can't raise urine pH enough to affect the development of kidney and other urinary stones," says UCI Health urologist Dr.

Muscle Function: Some studies suggest that alkaline water improves muscle strength and endurance, potentially beneficial for older adults struggling with age-related muscle decline.
