UCI-led study: Alkaline water doesn’t help prevent kidney stones

Roshan M. Patel, MD

Bottled water marketed as "alkaline water" is unlikely to be an effective alternative for prevention of recurrent urinary stones, according to a UCI-led study.

"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. Roshan M. Patel, the paper’s senior author.

The paper was published in the January issue of The Journal of Urology®.
