BLIS K12™ Probiotics

BLIS K12™ is a specific strain of bacteria called Streptococcus salivarius K12™, which is found naturally in your mouth and throat. Our scientists discovered that while everyone has Streptococcus salivarius bacteria, only a very few have the specific beneficial BLIS K12™ strain which is active against bad bacteria.

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 ‘bad’ bacteria. This process is known as bacterial interference. Taking an oral probiotic will boost the levels of BLIS K12™ in the oral cavity and will actively crowd out the bad bacteria, which can negatively affect your health.  In addition to their ability to inhibit bad bacteria, BLIS probiotics support certain cells in the mouth, to boost the immune system.

 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 colonise effectively. Lozenges and powder are ideal 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 as they are shelf-stable in their dry format. The bacteria activate when in the mouth, where conditions are moist and warm. The longer it is in the mouth, the better the colonisation will be, and the more the bad 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 DailyDefence Junior means little ones can get the same benefits.

How do I get the most benefit from probiotics?

BLIS K12™ helps support the immune system as well as supporting a healthy ear, nose and throat which is linked to many health benefits. BLIS K12™ is the key ingredient in DailyDefence, DailyDefence Junior, ThroatGuard PRO, HoneyBlis, TravelProtect and FreshBreath. 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 more effective than trying to crowd out the bad bacteria that may take over at times of stress or illness.

Sometimes you may need an extra boost. If you have a scratchy dry throat or feel under the weather, you can take up to four lozenges a day. Try to take them as soon as you start feeling unwell to help give your immune system a boost. ThroatGuard PRO is our high-dose product for this very purpose. The same could be said for when you’re travelling and at higher risk of contracting airborne germs on an aeroplane. For example, taking TravelProtect – which has been specifically designed at a higher dosing regimen for travel immunity – can provide extra protection in the aeroplane environment where you can be exposed to a very high amount of bad bacteria in a short amount of time.
