About Probiotics

Probiotics, from the Latin preposition “pro,” which means “for” and the Greek word “biotic” meaning “bios” or “life” are beneficial live bacteria strains that work to help the body's immunity by crowding out bad bacteria with friendly bacteria.

Professor Emeritus John Tagg’s discovery of specific strains of friendly bacteria that have advanced ways of crowding out the bad bacteria has led his work to be focused on Streptococcus salivarius; the most abundant bacteria naturally present in the oral cavity. These bacteria reside in the mouths of healthy people and is an indication of healthy immune function and natural resistance to bad bacteria that enter through the mouth.

The understanding behind this scientific discovery is that most friendly bacteria work by ‘crowding out’ bad bacteria, thereby supporting our health. Our discovery also revealed that certain types of bacteria can also naturally produce additional substances made of peptides and proteins that inhibit the bad bacteria from coming back.

BLIS probiotics – BLIS K12™ and BLIS M18™ – are specific strains of Streptococcus salivarius. These are advanced probiotics because they not only crowd out the bad stuff – they inhibit them from coming back when they are under threat.

These proteins dubbed "Bacteriocin-like Inhibitory Substances" are the inspiration behind our company's name and patented strains - BLIS K12™ and BLIS M18™.

BLIS K12™ and BLIS M18™ have been extensively safety-tested and have been commercially used now for more than 15 years. Streptococcus salivarius is the dominant organism in a healthy oral cavity. It is naturally present in breast milk and is listed as a Biosafety Level 1 (safest) organism in the United States.

The Microbiome

The microbiome consists of microbes that are both helpful and potentially harmful. Most are symbiotic (where both the human body and microbiota benefit) and some, in smaller numbers, are pathogenic (promoting disease).

In a healthy body, pathogenic and symbiotic microbiota coexist without problems. But if there is a disturbance in that balance—brought on by infectious illnesses, certain diets, or the prolonged use of antibiotics or other bacteria-destroying medications—dysbiosis occurs, stopping these normal interactions. As a result, the body may become more susceptible to illness and disease.

BLIS K12™ and BLIS M18™ can support a healthy balance of bacteria.
