How Probiotics help with Immunity?

How do Probiotics help our Immune System?

*This blog has been updated on 29th May 2024

The immune system is a complex network of cells, tissues, and organs that work together to defend the body against harmful microorganisms like viruses, bacteria, and parasites. When functioning optimally, it can distinguish between the body's own healthy cells and foreign invaders, launching an attack against the latter to keep us healthy. However, it isn't always 100% effective, especially when encountering new or particularly aggressive pathogens. 

A significant portion of the immune system, approximately 70%, resides in the gut. This means that maintaining gut health is crucial for a robust immune system. BLIS offers a range of probiotics for immunity to support and enhance your immune system.

How Probiotics Support Your Immune System 

Probiotics play a vital role in supporting the immune system by promoting a healthy gut microbiome. These beneficial bacteria help balance the gut flora, crowding out harmful bacteria and enhancing the gut's ability to function effectively. Consuming probiotic-rich foods like yogurt and fermented products can introduce good bacteria into the gut. Additionally, taking scientifically proven probiotic supplements can further support gut health and, consequently, the immune system. 

The mouth also serves as a critical gateway to the body. Most pathogens enter through the mouth, whether by inhalation or contact with contaminated surfaces. Probiotics that support oral health can act as a "first line of defence" against these invaders. 

BLIS Probiotics and Immune Support 

Professor John Tagg of BLIS Technologies identified specific strains of 'friendly' bacteria, such as Streptococcus salivarius K12 and Streptococcus salivarius M18, which are abundant in the mouths of healthy individuals, but only around 2-5% of the population have these good bacteria in enough quantities to be supportive. His work has shown that these bacteria can crowd out harmful bacteria, enhancing immune function and resistance. 

BLIS K12™ is a specific strain of Streptococcus salivarius that not only inhibits harmful bacteria in the mouth and throat but also supports the immune defences in the upper respiratory tract. While everyone has some Streptococcus salivarius K12, most people lack sufficient beneficial BLIS K12™, making supplementation a beneficial option. 

Comprehensive Immune Support with UltraBLIS 

UltraBLIS combines BLIS K12™ with Bifidobacterium lactis HN019 and Lactobacillus acidophilus La-14 to create a powerful supplement that supports both gut and oral health. These strains are scientifically proven to enhance the immune system, making UltraBLIS a comprehensive probiotic solution. 

While probiotics are beneficial, they should be part of a holistic approach to health, which includes a balanced diet, regular exercise, adequate sleep, and stress management. Probiotics can provide significant support, but they are not a standalone solution. 

Frequently Asked Questions on Probiotics for the Immune System  

Do probiotics improve your immune system?  

Yes, probiotics can enhance the immune system by crowding out harmful bacteria and repopulating with beneficial bacteria. This helps strengthen the gut barrier, reducing inflammation and supporting the body’s natural defence mechanisms. 

Do probiotics stop you from getting sick?  

Probiotics can help support the natural immune system, reducing the frequency and severity of certain illnesses, particularly those related to the gut and respiratory tract. Probiotic products are health supplements and therefore cannot claim to treat, cure, or prevent disease. 

How do healthy gut bacteria help increase immunity in the human body?  

Healthy gut bacteria support the immune system by enhancing the gut barrier, reducing harmful inflammation, and producing substances that inhibit pathogen growth. They also communicate with the immune system to regulate immune responses, making the body more effective at fighting off infections.
