What is S. Boulardii
Saccharomyces boulardii – pronounced sac-car-oh-my-sees boo-lard-dee – is a well-known probiotic organism. While many people think it's a bacterium, Saccharomyces boulardii (also known as S.boulardii) is actually a form of yeast. It is a non-pathogenic and transient yeast, meaning it just passes through the gut without attaching to the gastrointestinal wall and proliferating.
Benefits of S. Boulardii
- Promotes a healthy, balanced gut microbiome
- Supports optimal digestive function and wellness
- Reduces diarrhea
- Supports travelers and those who have taken antibiotics
- May reduce levels of Candida albicans

How it Works
Most people think of yeast as something harmful, however, saccharomyces boulardii functions like the good bacteria in the gut. S.boulardii promotes balanced digestion by encouraging the proliferation of beneficial microorganisms and preventing infection-causing bacteria and yeast in your gut from growing out of control. For example, research has shown it can reduce levels of pathogenic bacteria like H.pylori and E.coli bacteria. A transient, non-pathogenic yeast, S.boulardii moves through the digestive tract, balancing the health of the microbiome and disrupting the ability of pathogens to adhere to the gut wall.
Studies show S.boulardii helps improve symptoms and quality of life in those with chronic and debilitating digestive conditions like IBS and ulcerative colitis.
Diarrhea is a common symptom of a disrupted gut microbiome, which allows pathogenic bacteria to grow out of control. Research has repeatedly shown that S.boulardii reduces antibiotic-induced diarrhea, so it's frequently prescribed by medical doctors to minimize antibiotic side-effects. It's also great for travelers who experience diarrhea when they visit foreign destinations and eat food that they may not be used to.
Additionally, as a non-pathogenic yeast, Saccharomyces boulardii may help to keep levels of the opportunistic yeast, Candida albicans, under control. This is great news for women in particular because candida overgrowth may lead to vaginal thrush.
