What is Saccharomyces Boulardii?

Saccharomyces boulardii is a unique probiotic yeast that has been extensively studied for its benefits in supporting digestive and immune health. Unlike traditional bacterial probiotics, which are typically strains of Lactobacillus or Bifidobacterium, S. boulardii is a beneficial yeast that functions differently in the gut.

Originally discovered in the 1920s by a French scientist observing that people in Southeast Asia who consumed a particular type of lychee and mangosteen skin had lower incidences of digestive distress, S. boulardii has since been widely used as a probiotic supplement.

How Does Saccharomyces Boulardii Work?

S. boulardii supports gut health by:

• Restoring Balance in the Microbiome – Helps maintain a healthy gut environment by competing with harmful bacteria.

• Supporting Gut Barrier Integrity – Strengthens the intestinal lining to prevent leaky gut and inflammation.

• Producing Bioactive Compounds – Generates substances that inhibit the growth of harmful bacteria and promote beneficial microbial balance.

• Enhancing Immune Function – Modulates immune responses to help the body defend against pathogens.

Who Can Benefit from Saccharomyces Boulardii?

S. boulardii may be particularly beneficial for individuals experiencing:

• Antibiotic-Associated Diarrhea (AAD) – Since antibiotics can disrupt gut flora, S. boulardii helps replenish beneficial microbes and prevent diarrhea.

• Traveler’s Diarrhea – Helps protect against digestive disturbances commonly experienced while traveling.

• Irritable Bowel Syndrome (IBS) & Inflammatory Bowel Disease (IBD) – Can help manage symptoms such as bloating, diarrhea, and gut inflammation.

• Clostridioides difficile (C. diff) Infections – May aid in reducing the recurrence of this serious bacterial infection.

• Leaky Gut & Chronic Inflammation – Strengthens the gut lining to reduce permeability and inflammation.

• Candida & Yeast Overgrowth – As a beneficial yeast, S. boulardii does not contribute to Candida overgrowth and may help maintain a balanced gut microbiome.
