Bio-Kult Pro-Cyan is a triple action formulation scientifically developed with cranberry extract (36mg PACs), two specifically selected live bacteria strains and vitamin A which contributes to the normal function of the immune system and the maintenance of mucous membranes which can be found lining the urinary tract.
