Title: Nutritional Supplementation for Extending Time Between Recurrent Urinary Tract Infections in Women: a Randomized Double Blind Cross-over Trial
Brief Summary: The study will test the ability of specially formulated nutritional supplement capsules to extend the time between recurrent urinary tract infections in women. This objective will be completed by enrolling women who have suffered from 3-4 uncomplicated UTIs in the past 12 months into a double blind placebo controlled cross-over trial. Cross-over and study completion are triggered by the next two UTI recurrences. The goal of the study is for the supplement to extend the time to the next UTI for study participants as compared to placebo.
