Bacillus coagulans is a probiotic bacteria species that forms spores and is resistant to high temperatures and acid in the gastrointestinal tract.
This probiotic is used to treat diarrhea, IBS (Irritable Bowel Syndrome), IBD (Inflammatory Bowel Disease), Clostridum difficile colitis and bacterial over-abundance in SBS (Short Bowel Syndrome).
Bacillus coagulans probiotic supplements are also effective for supporting the immune system, preventing respiratory infections in treating helicobacter pylori infections which can cause ulcers.
Bacillus coagulans produce coagulin (a protease-sensitive antibacterial substance) and lactic acid which have antibacterial properties.
Together with other strains of probiotic bacteria, these microorganisms help to combat the growth of unfriendly pathogenic bacteria in the intestinal system.



- Supports a healthy immune system & microflora

Bacillus coagulans was previously known as Lactobacillus Sporogenes, but researchers now distinguish it from other species of Lactobacillus probiotics.
Lactobacillus is the classification of Lactic-Acid Producing Bacteria. These bacteria are used in the production of milk and dairy products. They also produce lactic acid in the digestive tract, helping to break down foods and lowering the pH balance to make the environment inhospitable to harmful bacteria.
While Bacillus coagulans does produce lactic acid as well, it is not a Lactobacillus strain because it also forms spores. This differentiates it from many other probiotic species used in dietary supplements.
Bacillus coagulans is considered to be safe as a dietary ingredient and has been added to the Qualified Presumption of Safety list by the European Food Safety Authority.
This supplement is frequently used promote vaginal flora in women, improve bloating and abdominal pain, and boosting the function of the immune system and resistance to viruses and infections.
A number of different products with Bacillus coagulans cultures are available for sale today. It is most often found in the form of supplement capsules, typically combined with other species of probiotic bacteria to improve efficacy.
It is important to note that unlike other probiotic bacteria species, Bacillus coagulans microorganisms are not normally found in the human microflora. There is less clinical research available regarding the effects of this probiotic strain compared to many others.
However, some research suggests that this strain may be more hardy and have a greater degree of viability compared to certain lactobacillus bacteria. This species can be stored for long periods of time in desiccated form.
Bacillus Coagulans Effects
The primary reason for taking probiotic bacteria supplements is to seed the digestive tract with friendly microorganisms. These health-conferring bacteria promote a positive balance in the microflora of the gut, which can contribute to digestive health and support the immune system.
A clinical study published in the Journal of Nutrition in July 2015 showed that taking Bacillus coagulans (BC30) daily by adults (aged 65-80) increased beneficial groups of bacteria in the human gut and the production of anti-inflammatory cytokines.
This clinical study concluded that this probiotic strain had potential benefits to improve dysbiosis (microfloral imbalance) by balancing the microflora in older persons.
In vitro, this probiotic has been observed to help reduce fungal growth associated with Fusarium. Fusarium can cause a variety of infections in humans.
B. coagulans has also been shown to reduce the colonization of the intestinal tract by the pathogenic and vancomycin-resistant enterococcus bacterium.
A clinical study published in the Iran Red Crescent Medical Journal in April 2015 showed the peppermint oil capsule and Lactol tablet with Bacillus coagulans plus FOS (a prebiotic fiber had better results than the placebo in relieving GI (Gastrointestinal) disorders.
A notable decrease was seen in the duration, frequency and severity of abdominal pain associated with functional GI disorders.
Bacillus Coagulans and SBS
B. coagulans is sometimes recommended to combat the proliferation of harmful bacteria in patients with Short Bowel Syndrome.
SBS (Short Bowel Syndrome) is a malabsorption disorder associated mostly with the surgical removal of the small intestine, although it can also be a genetic disorder found in children. Symptoms include pain in the abdomen, dehydration, diarrhea, fatigue, malnutrition, steatorrhea (smelly oily or sticky stools) and weight loss.
The malabsorption of vitamins A, D. E. K, B9 (folic acid) calcium, magnesium, iron and zinc causes complications. These include anemia, bone pain, easy bruising, hyperkeratosis (skin scaling) muscle spasms and poor blood clotting.
Bacillus coagulans is the exception for probiotics in its ability to treat SBS pathogen bacteria overgrowth as most probiotics are recommended not to be used for SBS patients.
Bacillus Coagulans Side Effects
Bacillus coagulans has been affirmed as GRAS (Generally Regarded as Safe) by the FDA and is considered safe by the EFSA.
However, there is limited human research available to determine the full potential for drug interactions, contraindications and side effects from using this probiotic.
In generally, probiotic supplements are not recommended for anyone with an impaired immune system, individuals who have open surgical wounds or those using a catheter. Unless otherwise directed by a medical care professional, probiotics should not be taken during pregnancy.
It is recommended to take probiotics at least two hours apart from antibiotic medications; antibiotics can kill both the good and bad bacteria in the intestinal tract, which is why it is important to not take them together.
Bacillus coagulans are beneficial for treating diarrhea, infections, IBS and IBD conditions and for boosting the immune system. Speak to your doctor to find out whether this probiotic is appropriate for you.
