Bacillus coagulans is a probiotic, which is a type of beneficial bacteria. Use of dietary supplements containing it is said to aid in the treatment of many health conditions, including several digestive disorders.


In alternative medicine, Bacillus coagulans is used to treat the following health problems:

Bacillus coagulans is also said to stimulate the immune system. Some alternative medicine proponents claim that it can fight cancer as well.

In addition, it's thought that taking Bacillus coagulans while taking antibiotic medications may help protect against the side effects associated with antibiotic use (such as stomach troubles and yeast infections).


Although there is currently a lack of large-scale studies testing the effects of Bacillus coagulans, there's some evidence that this probiotic may offer certain health benefits. Here's a look at some findings from the available research.

Irritable Bowel Syndrome

Some research suggests that Bacillus coagulans may help treat certain symptoms of irritable bowel syndrome.

A small study published in Postgraduate Medicine in 2009, for example, indicates that Bacillus coagulans may help abdominal pain and bloating related to irritable bowel syndrome. For the study, 44 patients took either Bacillus coagulans or a placebo every day for eight weeks. At the study's end, those treated with Bacillus coagulans showed a significantly greater improvement in pain and bloating (compared to those given the placebo).

Additionally, a pilot study published in Methods and Findings in Experimental and Clinical Pharmacology in 2009 found that Bacillus coagulans may be helpful to irritable bowel syndrome patients suffering from diarrhea. In an eight-week-long experiment involving 52 diarrhea-predominant irritable bowel syndrome patients, researchers found that those given Bacillus coagulans experienced a significantly greater reduction in an average number of bowel movements per day than those given a placebo.

The Immune System

Bacillus coagulans may help boost the immune system and stave off virus-induced respiratory tract infections (such as the common cold and the flu, according to a small study published in Postgraduate Medicine in 2009. The study involved 10 healthy men and women, each of whom was given Bacillus coagulans daily for 30 days.

After their 30-day treatment, all of the study members were exposed to adenovirus (which causes respiratory illness) and influenza A (a strain of flu virus). Researchers found that using it significantly increased the production of cells that play a key role in the body's immune response. 


Because so few studies have looked into the health effects of Bacillus coagulans, little is known about the safety of long-term use of this supplement. However, there's some concern that the use of probiotics may trigger a range of side effects, including digestive issues like gas and bloating.

Since probiotics may interact with medications used to suppress the immune system, it's crucial to talk to your doctor before using Bacillus coagulans in combination with any type of immunosuppressant drug.

It's important to keep in mind that supplements haven't been tested for safety and dietary supplements are largely unregulated. In some cases, the product may deliver doses that differ from the specified amount for each herb. In other cases, the product may be contaminated with other substances such as metals. Also, the safety of supplements in pregnant women, nursing mothers, children, and those with medical conditions or who are taking medications has not been established. 


A number of other types of probiotics have been found to benefit health. For instance, Lactobacillus acidophilus may help relieve diarrhea, treat eczema, manage irritable bowel syndrome, and aid in diabetes control. What's more, Saccharomyces boulardii may help fend off both traveler's diarrhea and diarrhea associated with the use of antibiotics, as well as soothe certain symptoms of irritable bowel syndrome.

You can also increase your intake of probiotics by consuming cultured dairy products (such as yogurt or kefir) and/or fermented foods (such as sauerkraut, kimchi, miso, and tempeh).

Where to Find It

Many natural-foods stores and other stores specializing in dietary supplements sell Bacillus coagulans. You can also purchase supplements online.

Using Bacillus Coagulans for Health

Due to the limited research, it's too soon to recommend Bacillus coagulans as a treatment for any condition. It's also important to note that self-treating a condition and avoiding or delaying standard care may have serious consequences. If you're considering using it for any health purpose, make sure to consult your physician first.
