K12 Probiotics kill Bad Breath and Prevent Infection

If your bad breath just isn’t going away, no matter what you do, then perhaps it’s time you switched to K12 probiotics. These all-natural specialty breath fresheners fight fire with fire, using bacteria to combat the odor-causing microbes that live in your mouth. And they really work, as three separate studies just reaffirmed.

The news is pretty exciting, but it isn’t all that surprising. After all, TheraBreath has been making use of probiotics for years. Still, it’s nice to learn that we stake our reputation on a product that truly neutralizes chronic halitosis.

The first study appeared in the journal FEMS Immunology and Medical Microbiology. Published by a team of Italian scientists, the paper reported that quite a few bacterial strains can make BLIS, the “magic bullet” of K12 probiotics.

BLIS, or bacteriocin-like inhibitory substances, are a group of proteins produced by certain species of microbes. Unlike the compounds given off by most oral bacteria, which simply stink, BLIS has a special purpose: It makes it harder for other microorganisms to live.

Essentially, BLIS is a naturally occurring antimicrobial agent. Think of it as salt sown in the earth to keep anything from growing there – when BLIS-producing microbes take up residence on your tongue, they quickly muscle out the odor-causing species, leading to long-term fresh breath.

In the Italian study, researchers found that 24 different strains of bacteria produce BLIS, most of them being subtypes of the same species – Streptococcus salivarius K12. As a bonus, the group noted that S. salivarius also seems to prevent the growth of S. pneumoniae, a microbe responsible for sinusitis and middle ear infections.

A second study, this one conducted by Japanese and Canadian microbiologists, added that K12 probiotics appear to prevent thrush (in addition to bad breath). The group discovered this effect when they found that BLIS inhibits the growth of Candida albicans, the fungus responsible for the oral yeast infection known as “thrush.” Their results appeared in the journal Applied and Environmental Microbiology.

The third and final investigation, which took place in Switzerland, found that S. salivarius K12 also inhibits the spread of yet another oral bacteria, the notoriously stinky Solobacterium moorei.

In their report in the journal Archives of Oral Biology, the team wrote that “S. salivarius K12 has antimicrobial activity against bacteria involved in halitosis. This strain might be an interesting and valuable candidate for the development of an antimicrobial therapy for halitosis.”

It’s too late for that – we already use it in our K12 probiotics kits!
