NOW OralBiotic lozenges feature the clinically studied probiotic strain BLIS K12, a strain of Streptococcus salivarius naturally found in the mouth. This beneficial bacterium is commonly one of the first probiotic species acquired in early life and plays a role in maintaining a balanced oral microbiome. When used regularly, BLIS K12 helps support healthy mouth, throat, ear, and nose environments while also helping to maintain fresh breath. These lozenges are suitable for both children and adults and are gluten-free.
