Unlock the Power of the BLIS K12™ Probiotic Strain

One of the active ingredients in BioNaze

What is BLIS K12?

BLIS K12™ (Streptococcus salivarius K12) is a well-studied probiotic strain naturally found in the mouths and throats of some healthy children and adults. Professor John Tagg, a renowned microbiologist, discovered the strain. His pioneering research advanced the understanding of beneficial bacteria and their role in oral health.

Professor Tagg’s interest in Streptococcus pyogenes began with a personal experience that shaped his scientific career. While researching at the University of Otago in New Zealand, he identified BLIS K12™, a naturally occurring strain of Streptococcus salivarius. It produces bacteriocins that can inhibit the growth of Streptococcus pyogenes in laboratory settings, leading to further research into its potential role as an oral probiotic for supporting throat and oral health.

Regular use of BLIS K12™ may help support a balanced oral microbiome by promoting beneficial bacteria in the mouth and throat. A balanced microbial environment may help limit the growth of undesirable bacteria associated with certain oral health concerns. Learn more about the top scientifically backed probiotics here.

What Does BLIS K12™ Do?

BLIS K12™ (Streptococcus salivarius K12) has been studied to colonize the oral cavity by attaching to the surfaces of the mouth and throat. This may help support a balanced oral microbiome. Through bacterial interference, it competes with other microorganisms for space and nutrients.

BLIS K12™ may also support the oral immune environment. However, more research is needed to understand these effects fully. These characteristics make BLIS K12™ a popular choice for supporting daily oral health. This includes helping to maintain fresh breath.

Beneficial bacteria thrive in the warm, moist environment of the mouth. Longer contact time with oral tissues can improve colonization. Lozenges dissolve gradually, allowing more time for this interaction. This makes them a practical delivery method for supporting colonization.

Discover the Top BLIS K12™ Health Benefits

BLIS K12™ (Streptococcus salivarius K12) is a specific probiotic strain widely examined for its potential to support oral and immune health. It helps maintain a balanced oral microbiome. Under the right conditions, it may encourage beneficial bacteria and limit the growth of certain microorganisms. Incorporating BLIS K12™ into your daily routine may support overall oral wellness. Below are selected research findings exploring its potential benefits.

Potential Support for Recurrent Streptococcal Pharyngotonsillitis in Children

Clinical research in Milan studied BLIS K12™ (Streptococcus salivarius K12). The study suggests it may help reduce recurring streptococcal pharyngotonsillitis in some children. It may work by inhibiting the growth of Streptococcus pyogenes. More studies are needed to confirm these findings in larger groups.

Potential Support for Oral and Upper Respiratory Health

BLIS K12™ may support oral and upper respiratory health. It may help maintain a balanced oral microbiome. Some clinical research reported fewer recurrent pharyngeal infections in certain pediatric populations. Studies also found lower rates of streptococcal infections and acute otitis media. However, further well-designed clinical studies are needed to confirm these findings.

Potential Support for Managing Halitosis (Bad Breath)

A clinical study looked at children with halitosis. It found that BLIS K12™ (Streptococcus salivarius K12) improved their breath odor. This was observed when used after oral disinfection with chlorhexidine. More than 90% of parents reported noticeable improvements. Researchers have proposed another benefit. They suggest that a balanced oral microbiome may help maintain naturally fresh breath. However, more research is needed to better understand this relationship.

Potential Support for Oral Microbial Balance

Laboratory research suggests BLIS K12™ may inhibit the growth of Candida albicans. This fungus is commonly associated with oral candidiasis. These findings, published by the American Society for Microbiology, are promising. However, more clinical studies are needed to see if similar benefits occur in humans.

Potential Support During Oral Mucositis

Researchers are studying whether BLIS K12™ can help with oral mucositis from cancer treatment. The current evidence is preliminary. More clinical studies are needed before drawing conclusions.

Support for a Healthy Oral Microbiome

BLIS K12™ may support a balanced oral microbiome. It may facilitate the development of beneficial bacteria. This may help maintain a balanced environment in the mouth and limit harmful pathogens, lowering the risk of dental caries and gum disease. A balanced microbiome can contribute to overall oral health when combined with good hygiene practices. More research is needed to understand its effects on specific oral conditions.

Ongoing Research Into Immune-Related Conditions

Rheumatoid arthritis (RA) is an autoimmune ailment that affects roughly 0-5-1% of adults. It arises when the immune system erroneously attacks the joints, resulting in discomfort, swelling, and inflammation.

Emerging evidence suggests probiotics may play a supportive role in immune regulation. One preclinical study found that BLIS K12™ reduced disease severity in mice. Whether similar effects occur in humans remains unknown, and additional clinical research is required before conclusions can be drawn regarding its role in RA.

Emerging Research in Psoriasis

Psoriasis is a chronic type of autoimmune condition that affects around 125 million people worldwide. It causes red, dry, itchy, and scaly skin due to immune system dysfunction.

Preliminary research has probed into the potential role of BLIS K12™ in several immune-related conditions, including psoriasis. However, the current evidence is limited. Additional investigation is required before any conclusions can be drawn.

Promotion of Overall Oral Health

In addition to supporting a balanced oral microbiome, regular use of BLIS K12™ may complement good oral hygiene habits. When combined with routine brushing, flossing, and professional dental care, it may contribute to long-term oral wellness.

Where To Buy BLIS K12™

Today, a variety of probiotic supplements contain the BLIS K12™ (Streptococcus salivarius K12) strain. Products like BioNaze combine BLIS K12™ with other probiotic strains. These are selected for oral and upper respiratory use.

Probiotic lozenges and powders are best for optimal delivery. They’re designed for the mouth and throat and provide prolonged contact with oral tissues. This may support bacterial colonization more effectively than other delivery methods.

Recommended Dosage for BLIS K12™ Probiotics

BLIS K12™ (Streptococcus salivarius K12) may support oral and throat health. It may also contribute to normal immune function. Like many probiotics, daily use is key. Consistent use helps maintain beneficial bacteria in the mouth.

Some product guidelines suggest taking up to four lozenges per day for extra oral health support. This may be helpful during times of mild throat discomfort or while traveling. Some people begin supplementation at the first sign of symptoms. However, more clinical research is needed to confirm if this approach is effective.

Travel, particularly air travel, may expose individuals to shared environments. Some people choose to include oral probiotics such as BLIS K12™ as part of their daily wellness routine while traveling.

Safety, Side Effects, and Storage

A clinical study on the daily use of BLIS K12™ (Streptococcus salivarius K12) reports a favorable safety profile. Study participants showed no significant adverse effects. However, individual responses to probiotics can vary. Anyone with underlying medical conditions or compromised immunity should consult a healthcare professional before use.

In 2019, a preparation with Streptococcus salivarius K12 received Generally Recognized as Safe (GRAS) status. This notice was granted through the U.S. Food and Drug Administration’s (FDA) notification process for its intended use. GRAS status means experts have evaluated the supplement’s safety for specific use. It does not mean the FDA approves any health or therapeutic claims.

When stored according to the manufacturer’s instructions, probiotic powders and lozenges are generally formulated to remain stable for up to two years. Refrigeration is unnecessary. To help preserve product quality, store the supplement in a cool, dry place, particularly in hot or humid climates.
