BLIS K12® is the first probiotic specifically developed to support ear, nose and throat health and to support immune system health. BLIS K12 is an extremely safe yet powerful strain of a probiotic called Streptococcus Salivarius which is one of the most numerous probiotic strains found in the mouth of healthy individuals.  However, only a small percentage of people have naturally occurring S. salivarius with the health-supporting attributes of BLIS K12. The BLIS K12 strain was originally discovered as scientists tracked a healthy child with exceptional throat health over several years. Scientists found that a particular strain of S. salivarius (later named BLIS K12) was associated with ear, nose, and throat (ENT) health.

BLIS K12® is an advanced probiotic for the oral cavity (mouth) and upper respiratory tract. It is a specific and proprietary strain of S. salivarius which helps support fresh breath naturally while promoting ENT immune health. It is safe and effective for children and adults and is supported with over 30 years of research.

BLIS K12® can be used in many unique delivery formats. Ideal applications for BLIS K12 are those that allow prolonged contact with the mouth, such as chewable tablets or lozenges, fast-melt tablets, chewing gum, stick packs, and powders.
