Patient Education

Saccharomyces Boulardii


What is it? Saccharomyces boulardii is a yeast believed to be a strain of Saccharomyces cerevisiae. It is likely effective for treating certain types of diarrhea.

Saccharomyces boulardii is called a "probiotic," a friendly organism that helps to fight off "bad" organisms that might cause diseases. Saccharomyces boulardii is different from other strains of Saccharomyces cerevisiae, commonly known as brewer's yeast and baker's yeast.

Saccharomyces boulardii is most commonly used for treating and preventing diarrhea, including rotaviral diarrhea in children. It has some evidence of use for other types of diarrhea, acne, and a digestive tract infection that can lead to ulcers. There is no good evidence to support using Saccharomyces boulardii for COVID-19.
