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™ probiotic is credited to Professor John Tagg who dedicated his life’s work to research in microbiology.

BLIS Probiotics containg BLIS K12

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 increase 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 crowd out bad bacteria, BLIS probiotics support certain cells in the mouth, to support the immune system. This is another reason people take BLIS K12™ probiotics for bad breath. 

How does BLIS K12™ work?

Years of research went into finding a way to deliver BLIS K12™ probiotics to the mouth and throat in such a way that they 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 BLIS K12™?

BLIS K12™ helps support the immune system as well as a healthy mouth and throat which is linked to many health benefits*. BLIS K12™ is the key ingredient in ThroatGuard PRO, DailyDefence Junior, DailyDefenceHoneyBlis, TravelProtect, and FreshBreath Kit.

Sometimes you may need extra support. 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 helping hand. 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 immune defence – can provide extra support in the aeroplane environment where you can be exposed to a very high amount of bad bacteria in a short amount of time.

Or, as a professional athlete, you need to have the best support to remain healthy and on top of your performance. That’s where our extra strength oral probiotic ElitePRO comes into play. Tested for WADA banned substances, ElitePRO provides athletes with a high dose of BLIS K12™ to support the health of the mouth and throat when you’re pushing your physical and mental boundaries.

Why BLIS K12™ Probiotics Are Important

BLIS K12 probiotics are important because they help increase levels of beneficial bacteria in the oral cavity. You can take your BLIS K12 probiotic to help support your immune system, upper respiratory system, and overall oral cavity. You can also take a BLIS K12 probiotic for freshening bad breath.

BLIS K12 probiotic is an oral probiotic that lives naturally in a healthy mouth and throat. It is a specific strain called Streptococcus salivarius K12, which is found naturally in healthy adults and children. 

Our scientists discovered that even though everyone has Streptococcus salivius bacteria present, it is uncommon for people to have the specific K12 strain. By taking BLIS K12 probiotics, your mouth will effectively colonize bacteria so that you keep the good bacteria and crowd out the bad bacteria.

What Does BLIS K12™ Help With?

Dental Probiotics BLIS K12 helps to support healthy levels of beneficial bacteria in your oral cavity. It can also help support your immune system, upper respiratory system, and overall oral cavity, and can help freshen your breath. 

For it to properly help you, you should take BLIS K12 regularly, one or two doses daily, to maintain the healthy bacteria in your mouth and throat and crowd out the bad bacteria. 

The BLIS K12 probiotic bacteria activates in your mouth because of the warm and moist environment, helping it to be more effective. The longer you keep the lozenge in your mouth before swallowing, the better it will work to crowd out the bad bacteria living in your mouth.
