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. There is controversy about its effectiveness (Hayes 2016, Ehrhardt 2016, MedlinePlus 2015, Szajewska 2015) 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) . 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.
