Dietary supplement made from D-mannose, which is naturally present in the human metabolism. D-mannose binds to E. coli bacteria and prevents them from adhering to the walls of the urinary tract. Thus, the bacteria can be easily eliminated from the body during urination. This composition contributes to the care of urinary tract infections of the bladder (caused by E. coli) and the prevention of recurrent urinary tract infections (bladder infections or cystitis).
