Drinking cranberry juice has long been one of the most popular remedies for UTIs. Experts debate the effectiveness of this home remedy, but research shows the active ingredients in cranberries may modestly reduce the attachment of infection-causing bacteria to the bladder wall. However, benefits probably require a lot of juice, and many brands contain too much sugar and water to be worthwhile. Cranberry capsules may also help, as they offer a concentrated amount of the active ingredient. It is important to note that while cranberry juice could be a factor in preventing or reducing the severity of a UTI, it is unlikely to cure an already-established infection.
