D-Mannose is a naturally occurring sugar that adheres to E. coli bacteria preventing their attachment to urinary tract walls, which supports urinary tract health, helps prevent recurrent UTIs, and provides a non-antibiotic approach to managing susceptibility to urinary infections.
How to Take D-Mannose
D-Mannose is typically dosed at 1500-2000 mg daily for prevention or 1000 mg every 2-3 hours during active UTI symptoms, best taken with water on an empty stomach, and works specifically for E. coli-based infections which account for approximately 90% of UTIs.
