The Active Ingredient Is: Streptococcus salivarius M18 (BLIS M18)

Streptococcus salivarius M18 is a probiotic bacterial strain that helps balance your oral microbiome. It is delivered as a vegetarian lozenge so it acts right in your mouth and is linked to producing antimicrobial peptides that help modulate the oral bacterial environment.

This version comes as a vegetarian lozenge containing a probiotic organism aimed at promoting a healthy oral flora and supporting gum comfort and resilience by targeting the mouth's microbial balance.

What Does Streptococcus salivarius M18 Do?

Streptococcus salivarius M18 helps curb harmful oral bacteria and support gum health by contributing to a balanced mouth microbiome, while the accompanying ingredients in the formula further help local immune responses in the gums.

The combination, together with Immuno-LP20, offers extra support to maintain normal inflammatory responses in the oral cavity and helps keep a comfortable, resilient mouth environment.
