DailyDefence Junior is a daily probiotic powder for the littlest members of your family, aimed at supporting ear, nose & throat health.​


Probiotics are live bacteria and yeasts that provide numerous health benefits when consumed in adequate amounts. While bacteria are often associated with illness, not all bacteria are bad. In fact, our bodies are home to trillions of bacteria, many of which are beneficial and essential for optimal health.

Probiotics for kids, such as DailyDefence Junior, are specifically formulated to introduce these beneficial bacteria into your child's system. These friendly bacteria help restore and maintain a healthy balance in their gut, which in turn supports their immune system, digestive health, and even dental health.


The tunnels that connect a child's ear, nose, and throat are much smaller than those of adults, which means they are more prone to accumulating nasty bacteria.

Every day, the things they eat, drink, and breathe introduce new bad bacteria that try their best to displace the beneficial bacteria. This continuous struggle for space can disrupt the balance of good bacteria in their mouth and throat, which can then affect their overall health and wellbeing.


Our DailyDefence Junior probiotic is safe and beneficial for kids, from 6 months +.

However, kid's probiotics are not recommended for babies under 6 months of age, unless otherwise advised by a healthcare professional.

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.

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.
