Product FAQs

What is an advanced probiotic?

Probiotics are good bacteria that have been characterized for their beneficial properties. 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. Not all probiotic strains can do this. BLIS K12™ and BLIS M18™ are both advanced probiotics strains because they have this additional capability.


What is S. salivarius?

Streptococcus salivarius is a species of spherical, gram-positive, facultative anaerobic bacteria that is both catalase and oxidase negative. S. salivarius colonizes (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 (Bacteriocin-like Inhibitory Substances) which are peptides that display interspecies inhibition.


What are oral probiotics? How do they differ from other probiotics?

Most probiotics are targeted towards the gut and digestive tract. Oral probiotics are those that support the mouth and throat, protecting the oral cavity. 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.


What is the benefit of taking an oral probiotic?

In an ideal situation, everybody would have the right balance of microbes in their oral cavity. Unfortunately this is not the case. For a small portion of the population (about 2%) they already have the natural presence of BLIS-producing Streptococcus salivarius (the good stuff). For the rest of us, a Blis probiotic will boost the oral cavity with these healthy bacteria and support good oral health. This is known as ‘bacterial interference’.

Blis probiotics are intended to help protect the mouth and throat, creating a forcefield to support oral health. The properties in Blis probiotics also work to crowd out bad bacteria that causes halitosis.


Is it true that the active ingredient in both ThroatGuard PRO / DailyDefence and FreshBreath is the same? If so, why do I need to purchase both products? And if so, is it safe?

The lozenges in our ThroatGuard PRO / DailyDefence and FreshBreath kits are the same – BLIS K12™. However, for people who suffer from bad breath (halitosis), it is important they use the antibacterial mouthwash and tongue scraper as directed. The FreshBreath kit is a specially designed concept which removes the bacterial layer that forms on the mouth and aims to repopulate the oral cavity with good bacteria (Streptococcus salivarius K12).


I’ve been using the FreshBreath kit for several months now and I’m experiencing fantastic results. Should I continuously use it all the time, or take a break for a while?

We’ve found that continuing to use the FreshBreath kit achieves long-term sustained fresh breath. Therefore, the FreshBreath kit should be made a regular part of your dental hygiene routine. We know that there is some ongoing effect when taking BLIS K12™ but it does drop off if not maintained so using one FreshBreath kit will not stop bad breath forever.


My child has strep throat and is currently on antibiotics. Should I start him on Blis Probiotics now or wait until he has finished the antibiotics?

We would recommend beginning Blis Probiotics the day after the course of antibiotics is complete. It is important to take the full course of antibiotics as they will kill off the bad bacteria.  But they also kill the ‘good’ bacteria – so the optimum time to recolonize the oral cavity quickly with good bacteria (BLIS K12™) is immediately following antibiotics.


Is it okay to take Blis Probiotics straight after food or cleaning teeth?

It’s fine to take lozenges when you wish and you can take up to 4 lozenges in one day. If you are taking it during the day it is best not to eat or drink at least 45 minutes after taking the lozenge. At night, you should take the lozenge after brushing your teeth.


Will BLIS K12™ or BLIS M18™ help with recurring mouth ulcers?

We have not conducted any trials in this area so we are unable to say if this is an area that Blis Probiotics can be utilized for.


What is the best form of BLIS K12™ and BLIS M18™? Lozenges? Gum? Powder?

We typically produce BLIS K12™ and BLIS M18™ in lozenge form as it is the most effective way to colonise the mouth and throat with the good bacteria.  Allowing the lozenge to dissolve slowly on the tongue gives it the best opportunity to colonize in the mouth and throat. We also have a powdered form which is suitable for toddlers who would struggle to suck on a lozenge.


What is the bacteria count for your products?

We measure the bacteria count in CFU: colony forming units at the date of manufacture. ToothGuard and ToothGuard Junior (BLIS M18™) contains 2.50 billion CFU/dose. ThroatGuard PRO (BLIS K12™) contains 2.50 billion CFU/dose, DailyDefence (BLIS K12™) contains 1.25 billion/dose. TravelProtect (BLIS K12™) contains 1.5 billion CFU/dose. DailyDefence Junior (BLIS K12™) contains 1.25 billion CFU/dose. HoneyBlis (BLIS K12™) contains 1.0 billion CFU/dose

Can BLIS K12™ and BLIS M18™ be taken together?

We recommend that while you can take both BLIS K12™ and BLIS M18™ in the same day – you should separate when you take the lozenges to get optimum benefit from each. We would recommend you take BLIS M18™ at night and BLIS K12™ in the morning. We would not recommend both lozenges are taken together or immediately after each other.


How does Blis TravelProtect work?

By taking a high dose over a short intense timeframe, you can boost your immune defences. The dosage of BLIS K12™ in TravelProtect is enough to support this response so that you have additional protection from bad bacteria. This is particularly relevant when travelling on airplanes as there are a lot of airborne germs filtering through the airplane air-conditioning system.


I’ve seen other branded products that contain BLIS K12™. Is this the same Blis probiotic?

Our company, Blis Technologies Limited, has the world patent for both the BLIS K12™ and BLIS M18™ strains. We produce our own finished goods which are available here, online, and in New Zealand pharmacies. But also supply ingredients to manufacturers who sell and distribute in overseas markets.

This is potentially why you have seen our oral probiotics under different brand names. If you are concerned about it being ‘real’ look for reference to Blis Technologies and the strain that the product contains.  Any product that includes our active ingredients need to correctly label their packaging and reference both the company and the strain name.


Do Blis probiotics contain sugar or gluten?

All Blis probiotics are sugar free and gluten free.


How should I store my Blis probiotics?

We recommend storing Blis probiotics below 25 degrees Celsius.  They are shelf-stable so they do not need to go into the fridge.


Are Blis probiotics safe to take alongside other medications?

While you shouldn’t incur problems taking a Blis probiotic alongside other prescription medication, you should seek the advice from your physician. If you are taking antibiotics you should complete the antibiotics before starting to take Blis probiotics.

All Blis probiotics are GRAS approved (Generally Recognised as Safe) by the United States Food and Drug Administration.


Are there any products that will interfere with BLIS K12™?

We do not recommend using Blis Probiotics at the same time as taking antibiotics.  Antibiotics will kill off probiotics.

Anti-microbial mouthwash also kill off good and bad bacteria. If you use anti-microbial mouthwash – always take Blis probiotics as the last step in your dental hygiene routine.
