NCT ID NCT06940622

First seen Nov 01, 2025 · Last updated May 01, 2026 · Updated 27 times

Summary

This study tests whether taking a daily supplement called D-mannose (a type of sugar) can prevent repeated urinary tract infections (UTIs) in post-menopausal women aged 55 and older. About 90 women who have had at least 2 UTIs in 6 months or 3 in a year will take either D-mannose or a placebo for 12 months. The goal is to see if D-mannose reduces the number of UTIs and the need for antibiotics.
