Overview

NOW D-Mannose provides 500mg of D-mannose per capsule, a naturally occurring simple sugar that supports urinary tract health. D-mannose works by binding to E. coli bacteria (the cause of 80-90% of UTIs) and preventing them from adhering to the urinary tract walls, allowing them to be flushed out during urination. Research supports D-mannose for UTI prevention, with some studies showing effectiveness comparable to antibiotics for recurrent UTIs.
