Gut Health

The Little-known Microbe That Supports Strong Lungs and Healthy Breathing

When you’re feeling stuffed up, wheezy, and “tight” when you try to breath, you probably don’t give much thought to your gut.

But your gut microbiome – the trillions of bacteria that live in your gut – plays a surprisingly big role in respiratory health. 

And when your gut microbiome is out of balance (more bad bacteria than good), you can be more susceptible to respiratory challenges like allergies, asthma, colds, and infections.

That’s why researchers are getting excited about probiotics – Both in how they support the growth of our beneficial bacteria AND how they improve respiratory health… Read more here

And one spore-based probiotic in particular has been shown to deliver respiratory benefits in study after study...  

Quick Answer: Your gut microbiome plays a surprisingly large role in respiratory health, and one spore-based probiotic strain stands out: Bacillus clausii. Like other spore probiotics, it survives heat, cold, and stomach acid to arrive in the gut alive. There it helps balance the microbiome and regulate immune-signaling proteins called cytokines, supporting a healthy response in the airways. In studies, including trials in young children, Bacillus clausii has been associated with fewer recurrent respiratory issues and faster recovery. It also offers wider benefits, from gut-barrier support to an unusual ability to survive alongside common antibiotics, which helps protect beneficial gut bacteria.

 

What Makes Spore-based Probiotics Unique?

Spore-based probiotics are tougher than standard store-bought probiotics: they survive extreme temperatures and stomach acid to reach the gut alive, where they crowd out harmful bacteria and help beneficial bacteria thrive. The Bacillus clausii strain adds particular benefits for respiratory health.

Spore probiotics aren’t the same as the regular probiotics you buy at the store. Unlike standard commercial probiotics, spore-based probiotics bring superior strength and resilience to the party. 

Among their many talents, spore probiotics can:

  • Survive extreme temperatures, from blazing heat to frozen tundra
  • Get through your highly acidic digestive system perfectly intact
  • Arrive in the gut 100% alive and ready to go to work
  • Neutralize and starve out harmful bacteria
  • Encourage your beneficial bacteria to thrive

Along with all of these plusses, the Bacillus clausii spore strain brings its own particular benefits… Especially when it comes to respiratory health. 

In fact, this particular probiotic has been tested in several human clinical trials – including trials with young children – for safety and effectiveness with extremely positive results...

Can Bacillus Clausii Help Kids Breathe Easier?

In a 3-month pilot study of 80 daycare children, those given Bacillus clausii recovered up to 4 days faster and had about 33% fewer respiratory issues than the control group, suggesting it may help with recurrent respiratory challenges in kids.

If you have kids in your life – especially young kids – you know they are germ magnets. 

Upper respiratory infections get passed around like Play-Doh in the daycares and school yards. That’s why so many children seem to always be sneezing and coughing and dealing with runny noses.

Turns out that Bacillus clausii may help with that.

In a 3-month pilot study, researchers found that Bacillus clausii helped address recurrent respiratory challenges in children. 

The study included 80 kiddos who attended daycare. Half of the children received Bacillus clausii and the other 40 didn’t... And the probiotic made a huge difference.

The children who got Bacillus clausii:

  • Felt better up to 4 days faster AND
  • Got about 33% fewer respiratory issues than the control group

 

How Does Bacillus Clausii Support the Immune System and Breathing?

Bacillus clausii helps regulate immune-signaling proteins called cytokines, encouraging ones that fight infection (like IFN-gamma) while reducing others (like IL-4) that can hamper a healthy inflammatory response, which supports respiratory health, especially in people with nasal allergies.

One of the ways Bacillus clausii keeps you breathing freely is by regulating immune system proteins called cytokines.

Bacillus clausii encourages extra production of specific cytokines (such as IFN-gamma) that help fight infections. 

At the same time, the spore probiotic reduces production of other cytokines like IL-4, which can hamper a healthy inflammatory response.

By helping the immune system in this way, Bacillus clausii drives optimal respiratory health, particularly in people with nasal allergies. 

Plus, Bacillus clausii also seems to help reduce allergic respiratory issues. In one clinical trial, teens with nasal allergies who took Bacillus clausii were able to significantly reduce the amount of allergy medicine they took.

What Other Benefits Does Bacillus Clausii Have?

Beyond breathing, studies link Bacillus clausii to a healthier gut microbiome and gut barrier, support for immune function against viruses, production of antibacterial compounds, and bone-health benefits. It also uniquely resists damage from several common antibiotics, helping protect beneficial gut bacteria during treatment.

Like other spore probiotics, Bacillus clausii improves overall health in a variety of different ways. 

Some of those benefits come from its positive impact on the gut microbiome… others come from the beneficial compounds (like nutrients) that Bacillus clausii produces.

Among its many benefits, Bacillus clausii has been shown in scientific studies to:

And check this out:

Bacillus clausii stands alone among its spore-based peers via its unique ability to resist damage from several common antibiotics. 

Normally, antibiotic therapies wipe out beneficial bacteria in the gut microbiome, paving the way for harmful, opportunistic infections (such as C. difficile). 

By surviving and standing its ground even during prolonged antibiotic treatment, Bacillus clausii helps maintain and restore a healthy balance of beneficial bacteria in the gut microbiome. 

In turn, Bacillus clausii helps stand guard at the gates of your gut and keep opportunistic pathogens from taking over. 

 

Frequently Asked Questions About Probiotics and Respiratory Health

How is the gut microbiome connected to respiratory health?
The trillions of bacteria in your gut help shape immune responses throughout the body, including the airways. When the gut microbiome is out of balance, you may be more susceptible to respiratory challenges like allergies, colds, and infections.

What is Bacillus clausii?
Bacillus clausii is a spore-based probiotic strain. Like other spore probiotics, it survives heat, cold, and stomach acid to reach the gut alive, and it has been studied specifically for respiratory and immune support, including in young children.

How does Bacillus clausii support breathing?
It helps regulate immune-signaling cytokines, boosting ones that fight infection while dialing down others that can drive an unhealthy inflammatory response. This is thought to support airway health, particularly for people with nasal allergies.

Is Bacillus clausii good for kids?
In a 3-month study of 80 daycare children, those given Bacillus clausii recovered faster and had about 33% fewer respiratory issues than the control group. The strain has been tested in several human trials, including with young children.

What other benefits does Bacillus clausii have?
Studies link it to a balanced gut microbiome, a healthy gut barrier, immune support against viruses, antibacterial compounds, and bone health. It also resists several common antibiotics, helping protect beneficial gut bacteria during treatment.
