Saccharomyces Boulardii Is Good For SIBO

Latest Research: Saccharomyces Boulardii Is Good For SIBO

Do you live in Ottawa? Are you wondering whether the probiotic Saccharomyces Boulardii is good for SIBO?

If so, you are in the right place.

Today I will talk about some latest research that shows that the probiotic Saccharomyces Bourlardi is good for SIBO.

Let’s begin by describing what SIBO is.

What Is SIBO?

SIBO, or Small Intestinal Bacterial Overgrowth, is a condition in which there is an overgrowth of bacteria in the small intestine, leading to symptoms such as heartburn, bloating, diarrhea, and constipation.

The small intestine is where most of our calories and nutrients are absorbed, so the inflammation from SIBO can lead to malabsorption issues.

Furthermore, the small intestines have the body’s highest percentage of immune cells.

SIBO can cause these immune cells to trigger inflammation, affecting the rest of the body.

This inflammation can cause symptoms such as non-alcoholic fatty liver disease, skin issues, body odour, depression, metabolic disorders, and even malabsorption of thyroid medication.

Let’s look at what Saccharomyces Bourlardi is.

What Is Saccharomyces Bourlardi?

Henry Bourlard discovered Saccharomyces Bourlardii.

Henry Boulard was travelling through Indo-China to discover a new type of yeast for winemaking.

Simultaneously, there was an outbreak of Cholera when Boulard observed that those who drank a particular tea did not have cholera-induced diarrhea.

Later, Boulard isolated the yeast used in the fermentation of the tea, which was Saccharomyces Bourlardi.

Since then, researchers have found Saccharomyces Bourlardi has anti-bacterial, anti-carcinogenic, and anti-parasitic properties.

Because they have these properties does not mean they are effective as a treatment.

A double-blind, randomized clinical trial is the best scientific way to show the effectiveness of a particular treatment.

Let’s look at a recent study examining whether Saccharomyces Bourlardi’s is good for SIBO.

Latest Research: Saccharomyces Boulardii Is Good For SIBO

A recent study published in January 2023 looked at the effect of Saccharomyces Bourlardii plus a Low Fodmap diet on people with bacterial overgrowth associated with IBS-D and its impact on the intestinal microbiota.

The results of the study showed the following:

  • Reduced Bacterial Overgrowth in the Small Intestines
  • Reduced Abdominal Pain
  • Reduced Diarrhea
  • Restoration of the Microbiota

The study comprised two groups, one on the low Fodmap diet and the other on Saccharomyces Bourlardii plus a Low Fodmap diet.

After two weeks, researchers saw a 40% improvement in SIBO for people on Saccharomyces Bourlardii plus a Low Fodmap diet and 30% for people on the low Fodmap diet.

This confirms typical clinical findings that people usually see symptom improvements after 2-3 weeks.

The typical time to expect optimal symptom changes when taking probiotics is 2-3 months.

Let’s now look at a simple protocol based on the above study.

A Simple SIBO Treatment Protocol Using Saccharomyces Bourlardii.

Based on the study, I recommend taking a Saccharomyces Bourlardii supplement such as Floramyces, one capsule twice daily.

If you do not see any change in your symptoms by the two-week mark, I recommend trying a different type of probiotic.

The two other types of probiotics include the following:

If you see improvements, continue for 2-3 months or until symptoms level out.

If some symptoms remain, you could try introducing another type of the types of probiotics.

Note: If you start a probiotic and get digestive upset for more than 2-3 days, change to a different type.
