BLIS M18™ Probiotics
BLIS M18™: an oral probiotic that naturally lives in a healthy mouth.

BLIS M18™ is the second strain of advanced oral probiotics bought to market by Blis Technologies.
What does BLIS M18™ do?
The mouth is a constant battleground – on a daily basis, billions of bacteria attempt to displace the natural and beneficial bacteria of the mouth, teeth and gums*. Even on properly brushed teeth, the bacteria that cause tooth decay and gum disease will find a place to hide*. This causes a change or imbalance of the normal bacteria in our mouths and can affect the health of our teeth and gums*.
BLIS M18™ colonises the mouth with beneficial bacteria by attaching to cells in the mouth and crowding out bacteria (competitive exclusion). *
Taking BLIS M18™ regularly – one or two lozenges a day – helps maintain a healthy population of the beneficial BLIS M18™ bacteria in the mouth*.
BLIS M18™ does not replace your usual dental routine. It has most benefit when used in conjunction with regular brushing and flossing. *
Taking an oral probiotic that contains BLIS M18™ will promote levels of beneficial bacteria in the oral cavity which may support the health of teeth and gums*.
How does BLIS M18™ work?
BLIS M18™ is best taken at night, after brushing and flossing teeth. BLIS M18™ bacteria activates in the mouth where conditions are moist and warm*. At night, the mouth produces less saliva which provides the ideal time for BLIS M18™ to colonise.* The longer BLIS M18™ is in your mouth before swallowing, the more effective it will be, and therefore more bacteria can be crowded out. That’s why a slowly sucked lozenge is recommended*.
Lozenges are an ideal delivery format because BLIS M18™ 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. BLIS M18™ is the key ingredient in Teeth & Gums with BLIS M18™.
How is BLIS M18™ different from BLIS K12™?
Both BLIS K12™ and BLIS M18™ are specific strains of Streptococcus salivarius but they work to do different things.
For example, we know that BLIS K12™ can help support upper respiratory health, throat health and bad breath*. BLIS M18™, on the other hand help support teeth and gum health*.
There might be some cross-over in what both of these probiotics can do, however, we believe that each strain has a specific set of capabilities and we manufacture probiotics to be specific in their impact on overall well-being*.
BLIS M18™ has been granted GRAS status by the FDA (Generally Regarded As Safe).
