The mineral zinc boosts the immune system. It also coats the mouth and throat, preventing some germs from taking up residence there. When unwanted invaders can't get a strong foothold in the mouth or throat, they often struggle to proliferate, shortening the duration and intensity of a cold or flu. All of this in a great-tasting lozenge!
