Amazing

For years I have been getting at least 3 chest infections a year. Since I have been taking a lozenge every night, I have not had one cold or any type of infection. Amazing at my age (71)

O/seas travel with BLIS

I was first introduced to BLIS in an earlier version while travelling around NZ. I used it while on cruises since then. I haven't used the current ThroatGuard or the Travel version yet but I'm committed wholeheartedly to BLIS. It's a must have when you're travelling anywhere !

Keeping healthy in the age of Covid

Read some reviews on studies about Blis ThroatGuard PRO and got some for Hubby & me. It's good to have another weapon in the armory against Covid & other nasty bugs.

My older kid kept having bad bouts of upper respiratory problems. Had to be on antibiotics every other month. Since Oct'23, we started him on the ThroatGuard Pro & he is doing much better. We will continue using it and post a follow-up at a later time.

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.
