Question: Do probiotics that come in different forms, like gum or lozenges, really work?
Answer: There is some clinical evidence showing that probiotic gum or lozenges may be beneficial for conditions affecting the mouth or throat, such as gum disease and throat infections. There do not appear to be studies on their effects on gastrointestinal symptoms, as shown with probiotic pills, drinks and powders. You can learn more about probiotic gums and lozenges, plus evidence of other uses of probiotics, and our tests of popular products, in the Probiotic Supplements Review.
