This study aims to determine whether a cranberry concentrate reduces recurrent urinary tract
infections (UTIs) in women who consume it. About 150 adult women will participate in this
study. Subjects will be randomized (like flipping a coin) to take either cranberry capsule or
a placebo for 12 months. We expect cranberry supplement to have better results than the
placebo. Subjects will not know which supplement they are taking. The primary outcome is the
number of UTIs over 12 months.
