Does D-Mannose Actually Work for Utis?

D-Mannose shows promise for UTI prevention and treatment, though evidence remains limited. This simple sugar works by preventing E. coli bacteria from adhering to urinary tract walls, potentially reducing infection risk. Clinical studies suggest 2 grams daily may decrease UTI recurrence by up to 77% in women with frequent infections. However, most research involves small sample sizes and short durations. D-Mannose appears most effective against E. coli UTIs, which cause about 85% of uncomplicated urinary tract infections. While generally safe with minimal side effects, it should complement rather than replace antibiotic treatment for active infections.
