Your daily dose of good probiotic bacteria to keep the balance right in the mouth & throat.​

• Your daily dose of good probiotic bacteria to benefit the mouth & throat.​
• Every day, what you eat, drink and breathe introduces new unfavourable bacteria that try their best to displace the beneficial bacteria. This continuous struggle for space can cause a change or imbalance of the beneficial bacteria in the mouth and throat, which can then affect your overall health and wellbeing. ​
• Taken daily, DailyDefence with BLIS K12™ leaves no room for harmful bacteria. ​
• DailyDefence utilises BLIS K12™, a new generation of advanced oral probiotics, developed from a special strain of beneficial bacteria ​Streptococcus salivarius K12 (BLIS K12™) that is found to occur naturally in the mouths & throats of healthy adults and children. While everyone has these bacteria in their oral cavity, very few (2-5%) have high enough quantities of this specific strain to be effective. ​

My 4-year old daughter loves it!!!

I am so worried if my daughter won’t take it as she is very picky but she loves it and me too! She loves strawberry flavor and I love the vanilla. They taste good! Her pedia recommended this Blis K12 as she always gets sick every other week since the school started. They said JK always get sick but I get so tired from getting sick too. To the point I stopped counting how many times she got sick. I am so hopeful that this will help us not to get sick all the time. We are taking at least once a day after brushing teeth before went to bed. I will order more in the next 2 weeks just to make sure we won’t skip taking them.

I have been taking Daily Defence for years which I find helps keep my breath fresh. Double doses were a good preventative when travelling.

Unrivalled cure for my bad breath !

I’ve been purchasing blis products for some years now and will continue to do so. My bad breath issue has been helped massively. I’m a little disappointed that the costs have gone up so ordering from the uk 🇬🇧 is now a lot more expensive.

Thank you to the Blis team for this amazing product. I would have given a 5 star if the price was a little lower.

Very satisfied

We have been using Daily Defence with BLIS K12 for the last two years and it works absolutely perfect for me and my wife! The problem we had now and then with halitosis is now reduced to almost zero! The only problem is the shipping costs as we live in Sweden!

Why choose blis?

Here at BLIS we've decided to get back to basics, think of this like a BLIS 101 class, focusing on our core and pioneering products - oral probiotics, or probiotics for the mouth and throat.

Keep reading if you'd like to learn more about what oral probiotics are, how they work, and most importantly how you can benefit from them.

Backed by science

BLIS Probiotics champions healthy mouths for all through their innovative, scientifically developed and researched probiotics for the mouth and throat.

BLIS Probiotics are leaders when it comes to applying the science of​ probiotics to the mouth and throat by adding the good bacteria in to crowd out and target the harmful bacteria.

Frequently Asked Questions

Glad you asked! BLIS is an acronym for Bacteriocin-Like Inhibitory Substances - and the core of our science and advanced probiotics.

Probiotics are good bacteria that have been characterised for their beneficial properties. They work by rapidly reproducing and crowding out any bad bacteria. You might be familiar with probiotics aimed to maintain a good balance in the gut, but your gut is not the only place that has a microbiome worth keeping in balance.

Advanced probiotics are slightly different in that they also provide the benefit of producing bacteriocins (small proteins) that are inhibitory against other bacteria species. So, not only do they crowd out the bad bacteria, they inhibit them with bacteriocins.

However, not all probiotic strains can do this. BLIS K12™ and BLIS M18™ are both advanced probiotics strains that utilise Streptococcus salivarius, which means that they have this additional capability.

Streptococcus salivarius is a species of spherical, gram-positive, facultative anaerobic bacteria that is both catalase and oxidase negative. S. salivarius colonises (usually in chains) the mouth and upper respiratory tract of humans just a few hours after birth, making further exposure to the bacteria harmless in most circumstances.

Some strains of S. salivarius are marketed as a probiotic for oral health. Some strains of S. salivarius are found to produce BLIS (the above-mentioned bacteriocin-like inhibitory substances) which are peptides that display interspecies inhibition.

BLIS K12™ and BLIS M18™ are both specific strains of Streptococcus salivarius and the core of our oral probiotics.

As noted, most probiotics are targeted towards the gut and digestive tract.

Oral probiotics, however, are those that support the mouth and throat, protecting the oral cavity (a fancy way of saying mouth, teeth, gums and throat).

BLIS K12™ probiotics populate the mouth and throat with good bacteria, crowding out the bad. In science terms – this is known as ‘bacterial interference’.

By creating a forcefield, oral probiotics can support mouth and throat health. BLIS K12™ is also used in our FreshBreath kits which restore the balance of good bacteria to the oral cavity and can aid bad breath and halitosis.

BLIS M18™ works in a similar way but it is targeted specifically at the bad bacteria that can cause teeth and gum issues.
