BLIS K12™ Probiotics

BLIS K12™: an oral probiotic that naturally lives in a healthy mouth and throat.

BLIS K12™ is a specific strain of bacteria called Streptococcus salivarius K12™ which can be found naturally in the mouth and throat of some healthy adults and children. Our scientists discovered that while everyone has Streptococcus salivarius bacteria, it is not as common to have the specific beneficial BLIS K12™ strain.

The discovery of BLIS K12™ is credited to Professor John Tagg who dedicated his life’s work to research in microbiology. 

What does BLIS K12™ do?

BLIS K12™ colonises in the oral cavity by attaching to cells in your mouth and crowding out bacteria*. This process is known as bacterial interference or competitive exclusion*. Taking an oral probiotic that contains BLIS K12™ will promote levels of beneficial bacteria in the oral cavity which may help support the immune system, fresher breath, upper respiratory system and oral cavity overall*. 


How does BLIS K12™ work?

Years of research went into finding a way to deliver BLIS K12™ to the mouth and throat in such a way that it could colonize effectively. Lozenges and powder are ideal formats as the BLIS K12™ bacteria can stay alive in that format for at least two years when stored correctly. They do not have to be kept in the fridge – but if you live in a hot, humid environment, you may want to give them added protection by keeping them cool.

The bacteria activate when in the mouth, where conditions are moist and warm*. The longer the lozenge can be kept in the mouth before swallowing, the more effective it will be, and more of the bacteria can be crowded out*. That’s why slowly sucking on a lozenge is recommended*. However, for infants who are unable to suck a lozenge, the powder format of ThroatHealth for Kids is a great way to give them the benefits of BLIS K12*.

How do I get the most benefit from BLIS K12™?

BLIS K12™ helps support the immune system as well as helping maintain a healthy mouth and throat which is linked to many health benefits*. BLIS K12™ is the key ingredient in ThroatHealth, ThroatHealth for Kids, HoneyBlisTravelProtect, and FreshBreath Kit.

It’s important to take BLIS K12™ regularly – one or two doses daily – because maintaining the healthy population of bacteria in your mouth and throat is the best way to crowd out bacteria and support a healthy immune system overall.

BLIS K12™ has been granted GRAS status by the FDA (Generally Regarded As Safe).
