Theoretically cranberry juice is thought to reduce UTIs by preventing bacteria from sticking to the walls of the bladder, thus preventing infections. There is, however, limited evidence to suggest that cranberry juice is actually effective in the management of urinary tract infections. Some of the smaller studies showed a possible benefit for preventing UTIs in women with frequent urinary tract infections, however larger studies did not show any significant difference between women using cranberry juice and those who were not using cranberry juice.

Cranberry juice is not recommended as an alternative to treating urinary tract infections with antibiotics.
