Many people drink cranberry juice to prevent UTIs. There's some indication that cranberry products, in either juice or tablet form, may have infection-fighting properties. Researchers continue to study the ability of cranberry juice to prevent UTIs, but results are not conclusive.

If you enjoy drinking cranberry juice and feel it helps you prevent UTIs, there's little harm in it, but watch the calories. For most people, drinking cranberry juice is safe, but some people report an upset stomach or diarrhea.

However, don't drink cranberry juice if you're taking blood-thinning medication such warfarin, medications that affect the liver or aspirin.
