Understanding Saccharomyces Boulardii:

Saccharomyces boulardii is a beneficial yeast strain that has gained attention for its potential health-enhancing properties. Differing from typical yeast strains, Saccharomyces boulardii isn’t a harmful pathogen but rather functions as a supportive microorganism, offering an array of advantageous effects for the body.

Furthermore, unlike other yeast strains, it doesn’t belong to the Candida family and is not related to the Saccharomyces cerevisiae strain used in baking and brewing.

No. 1 – Gastrointestinal Health

One of the primary benefits of Saccharomyces boulardii is its positive impact on gastrointestinal health. This beneficial yeast helps to restore balance in the gut flora by supporting the growth of beneficial bacteria while restraining the proliferation of harmful organisms. This is especially the case during times of imbalance caused by antibiotics, infections, or other factors.  

No. 2 – Prevention of Antibiotic-Linked Diarrhea

One of Saccharomyces boulardii’s biggest uses is in helping to alleviate symptoms of diarrhea, whether stemming from infections, antibiotic use, or other factors. It does so by restoring the natural equilibrium of the gut.
While antibiotics are sometimes crucial for combating infections, they can occasionally disrupt the delicate balance of our gut ecosystem. Saccharomyces boulardii helps to prevent diarrhea associated with antibiotic use by preventing harmful bacteria, such as Clostridium difficile, from overpowering the system, while allowing beneficial bacteria to thrive.

No. 3 – Defense Against Traveller’s Diarrhea

I’m not sure we’ve discussed poo enough.. so let’s add another poo-related point!
The unpleasantness of traveller’s diarrhea will put a damper on any journey. Unsurprising to you now, Saccharomyces boulardii helps to reduce the risk of contracting traveller’s diarrhea in the first place, by strengthening gut defenses and thwarting the colonization of harmful pathogens.

No. 4 – Easing Irritable Bowel Syndrome (IBS) Discomfort

Many individuals grappling with irritable bowel syndrome often contend with uncomfortable symptoms like bloating, gas, and irregular bowel movements. Saccharomyces boulardii has the potential to alleviate these symptoms by encouraging a more balanced gut environment and mitigating inflammation.

No. 5 – Support for the Immune System

A healthy gut is closely linked to a strong immune system. By promoting a balanced gut microbiota and helping to prevent gut-related issues, Saccharomyces boulardii indirectly supports immune function. It enhances the gut’s barrier function, preventing harmful substances from entering the bloodstream. This, in turn, aids the immune system’s capacity to ward off infections and maintain overall health.

No. 6 – Regulation of Candida Overgrowth

Despite being a yeast itself, Saccharomyces boulardii can actually help combat the overgrowth of the pathogenic Candida yeast. It does so by competing for resources and producing compounds that inhibit Candida growth.
Since Saccharomyces boulardii is naturally antimicrobial, it produces compounds that inhibit the growth of harmful bacteria and pathogens. It does so by competing for nutrients and binding to the surface of intestinal cells, preventing the adhesion of harmful microorganisms. By competing with Candida for nutrients and adhesion sites in the gut, it curtails their excessive growth.

No. 7 – Management of Inflammatory Bowel Disease (IBD)

Research suggests that Saccharomyces boulardii might have a role to play in managing inflammatory bowel diseases like Crohn’s disease and ulcerative colitis. Its ability to modulate the immune response and reduce inflammation in the gut shows promise in alleviating symptoms and promoting remission.

At the very least Saccharomyces boulardii’s anti-inflammatory attributes may assist in managing symptoms and enhancing the quality of life for individuals with these conditions.


Saccharomyces boulardii is a fascinating yeast that offers a range of potential benefits for our digestive and overall health. From its ability to restore digestive balance to its support for the immune system and relief of various gastrointestinal issues, this beneficial yeast strain offers a holistic approach to better health.

Saccharomyces boulardii is undoubtedly a microorganism worth exploring further and it’s incredibly easy to incorporate into your wellness regime.

How to Take Saccharomyces Boulardii 

If you’re looking for a food-based source, you can definitely try introducing some fermented foods into your diet. Fermented foods such as sauerkraut, kimchi, miso, and tempeh, naturally contain a variety of bacteria and yeast strains that may support gut health. While Saccharomyces boulardii might not be the primary strain in these foods, the overall diversity can contribute to a balanced gut environment.
