PlaqueOff is added to food and controls plaque in cats and dogs, and is effective against bad breath and tartar. PlaqueOff is made from a specially selected and clinically tested arctic ocean alga, Ascophyllum nodosum. Free from artificial colours, preservatives, gluten and sugar. When the unique agents of the product reach the saliva, they effectively prevent oral bacteria from producing plaque, tartar and gum disease by disrupting the biofilm and affecting the ability of plaque to ‘stick’ to surfaces in the mouth.
