Saccharomyces boulardii

Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

A yeast strain isolated from various tropical fruits. Related to saccharomyces cerevisiae or brewer's yeast. Unicellular fungus which produces lactic acid used as a probiotic to regenerate the intestinal flora in case of infectious diarrhea or diarrhea associated with taking antibiotics.

Since the last update we have not found published data on its excretion in breast milk, but due to its lack of intestinal absorption it is considered safe during breastfeeding.

There is controversy about its effectiveness (Poncelet 2021, Williams 2010) and although it is considered a safe product in immunocompetent people, there have been cases of widespread infection by the fungus itself in the absence of immune deficiency. (Martin 2017)

Administration of probiotics and other live organisms is contraindicated in immunocompromised persons. (Poncelet 2021, Williams 2010)
