The Active Ingredient Is: Streptococcus salivarius K12 (BLIS K12)

Streptococcus salivarius K12 is a friendly bacteria strain used to help keep the mouth and throat area performing normally.

This form is delivered as a lozenge holding the BLIS K12 strain, with extra prebiotic and flavour components to help its stay in the oral space.

What Does Streptococcus salivarius K12 Do?

Streptococcus salivarius K12 helps crowd out odour-causing bacteria in the mouth and throat and might contribute to fresher breath, depending on clinical context. Scientific research suggests it could play a part in reducing recurrent throat and ear infections in children, and in supporting oral health through competitive inhibition of harmful bacteria.

This effect is discussed by Dr. Di Pierro of the University of Bologna, who notes the strain’s potential to shield against throat and ear infections and to support fresh breath.
