One of the active ingredients in Bionaze™
What Is BLIS K12?
BLIS K12™ (Streptococcus salivarius K12) is a unique strain of bacteria naturally found in the mouths and throats of some healthy children and adults. Professor John Tagg, a microbiologist who devoted his career to advancing our understanding of beneficial bacteria, is credited with its discovery.
A personal encounter inspired Professor Tagg’s journey into microbiology with Streptococcus pyogenes, the bacteria behind strep throat. While researching at the University of Otagu in New Zealand, he made a significant discovery. BLIS K12™ (Streptococcus salivarius K12), a natural strain of Streptococcus salivarius, can fight strep throat. It works by stopping the growth of Streptococcus pyogenes. This breakthrough unveiled its potential as a potent probiotic for throat health.
Regularly using this probiotic supports a healthy bacterial balance in the mouth and throat. It helps stop harmful bacteria from growing. These bacteria are a common cause of oral health problems. Learn more about the top scientifically backed probiotics here.
What Does BLIS K12™ Do?
BLIS K12™ (Streptococcus salivarius K12) works by colonizing the oral cavity and attaching to cells in your mouth. It outcompetes harmful bacteria through bacterial interference. Taking an oral probiotic increases the levels of beneficial bacteria in your mouth, helping eliminate bad strains that can harm your health.
Beyond crowding out harmful bacteria, it also supports specific cells in the mouth that strengthen the immune system. This dual action is one of the reasons many people turn to BLIS K12™ (Streptococcus salivarius K12) probiotics as an effective solution for combating bad breath.
Bacteria thrive best in the warm, moist environment of the mouth. The longer they stay, the more effectively they colonize, outcompeting harmful bacteria. Lozenges dissolve slowly, increasing contact between beneficial bacteria and oral surfaces. This helps the bacteria adhere better and colonize more effectively in the oral cavity.
Discover The Top BLIS K12 Health Benefits
BLIS K12™ (Streptococcus salivarius K12) is a unique probiotic strain recognized for its health benefits, primarily oral and immune health. It helps maintain equilibrium in the mouth’s microbiome. This balance helps prevent the spread of harmful bacteria, which can lead to health issues. Integrating the probiotic into your daily routine may improve overall wellness and encourage a healthier lifestyle. Below are some research studies highlighting the beneficial potential of BLIS K12™ (Streptococcus salivarius K12).
Prevention Of Streptococcal Pharyngotonsillitis
A Milan study found that BLIS K12™ (Streptococcus salivarius K12) helps prevent streptococcal pharyngotonsillitis in children. It works by stopping the growth of Streptococcus pyogenes. It reduces throat infections and lowers the risk of related complications.
Reduction Of Oral And Upper Respiratory Tract Infections
BLIS K12™ (Streptococcus salivarius K12) fights harmful bacteria that cause oral and respiratory infections. Studies show that regular use of this probiotic significantly reduces the incidence of pharyngeal infections. It also lowers the risk of streptococcal diseases and acute otitis media in young children.
Improvement Of Halitosis (Bad Breath)
In a clinical trial involving children suffering from halitosis demonstrated that BLIS K12™ (Streptococcus salivarius K12) given after oral disinfection with chlorhexidine significantly reduces bad breath. Over 90% of parents reported noticeable improvements in their children’s breath odor. This probiotic is also believed to contribute to the characteristic “baby breath” in infants by maintaining a balanced oral microbiome.
Protection Against Oral Candidiasis
Research by the American Society for Microbiology shows that BLIS K12™ (Streptococcus salivarius K12) protects against severe oral candidiasis. This probiotic controls the growth of Candida albicans, the fungus behind oral candidiasis. It prevents overgrowth and lowers the severity of infections.
Treatment Of Oral Mucositis In Cancer Patients
BLIS K12™ (Streptococcus salivarius K12) has shown promise in managing oral mucositis, a painful condition caused by radiation therapy in cancer patients. Studies show that it aids oral healing, helps reduce inflammation, and eases discomfort.
Support For A Healthy Oral Microbiome
BLIS K12™ (Streptococcus salivarius K12) goes beyond treating specific conditions. It promotes a healthy oral microbiome, which is crucial for overall dental hygiene. It supports the development of beneficial bacteria and helps limit harmful pathogens, reducing the risk of dental caries and gum disease. The result is better long-term oral health.
Management Of Rheumatoid Arthritis
Rheumatoid arthritis (RA) is an autoimmune ailment affecting 0.5–1% of adults. The immune system initiates an attack on the joints, causing joint pain, swelling, and inflammation.
Emerging research suggests probiotics may help manage RA. A recent study found that BLIS K12™ (Streptococcus salivarius K12) reduced the severity of RA in mice, both preventatively and therapeutically, though further clinical trials are needed to confirm similar benefits in humans.
Improvement Of Psoriasis
Psoriasis is a non-contagious autoimmune disease that affects around 125 million people worldwide. The condition causes red, dry, itchy, and scaly skin because T cells mistakenly attack skin cells.
A study examining the impact of BLIS K12™ (Streptococcus salivarius K12) on psoriasis revealed promising results. Participants who used the lozenges experienced a remarkable 75% or greater improvement in their condition. These findings suggest that probiotic supplementation could be a valuable option for managing psoriasis effectively.
Promotion Of Overall Oral Health
Beyond targeting specific infections, BLIS K12™ (Streptococcus salivarius K12) plays a vital role in maintaining oral hygiene. It helps prevent oral diseases, supports a healthy balance of beneficial bacteria, and contributes to long-term oral and throat health.
Where Can I Purchase BLIS K12?
The market offers a variety of probiotic supplements featuring the BLIS K12™ (Streptococcus salivarius K12) strain. Products like Bionaze incorporate additional probiotic strains to enhance their benefits.
To get the most out of a probiotic supplement, choose a lozenge or powder format. Studies reveal that the most effective way to deliver BLIS K12™ (Streptococcus salivarius K12) is by targeting the mouth and throat. These formats are ideal for supporting colonization, with research confirming their superior effectiveness compared to other methods.
How Often Should You Take BLIS K12 Probiotics?
BLIS K12™ (Streptococcus salivarius K12) supports your immune system while promoting a healthy mouth and throat, offering a range of health benefits. Like other probiotics, consistency is key. Taking the probiotic regularly is the best way to achieve optimal results.
Your body may need extra support at times. If you’re experiencing a scratchy throat or feeling unwell, you can take up to four lozenges daily. For the best results, start taking them as soon as you notice symptoms to boost your immune system.
This is especially useful when traveling. On airplanes, exposure to airborne germs is higher. Keeping the probiotic on hand can help protect your health when needed.
Safety, Side Effects, And Storage Considerations
A clinical study analyzing the daily use of the BLIS K12™ (Streptococcus salivarius K12) strain has consistently reported no side effects. For instance, a study conducted by the University of Otago in New Zealand found no adverse effects among participants or changes in their metabolic profiles.
In 2019, the FDA further endorsed a notice for the safety of probiotic strain by granting it “Generally Recognized as Safe” (GRAS) status. This designation, supported by expert evaluation, confirms that the strain poses no risk when used as intended.
Powder and lozenge probiotics can stay effective for up to two years if stored properly. No refrigeration is needed. However, in hot and humid climates, store them in a dry, cool place to prolong quality and potency.
