It contains an innovative combination of cranberry extract, D-mannose, common knotgrass and vitamin C. Cranberry is a natural help in thetreatment of frequent infections of the urinary tract. D-mannose acts in a simple way by firmly binding to surface strains of bacteria E. coli. The binding affinity of E.coli to D-mannose is higher than the affinity of binding to the cells of the bladder. Bacteria bound to D-mannose is excreted from the body by urination. Common knotgrass helps excrete water through the urinary tract. Vitamin C contributes to the normal function of the immune system.
