Evidence Summary
Studies have concluded that Saccharomyces Cerevisiae can support the immune system and reduce inflammation resulting from bacterial infection. It may also be helpful in treating diarrhea (4).
Saccharomyces Cerevisiae contains compounds including, beta-1,3 glucan and glutathione, which are associated with enhanced immune function (5).
It is rich in polysaccharides, which are contained in the cell wall of Saccharomyces Cerevisiae. The two major polysaccharides, constituting up to 90% of the cell wall dry weight, are α-d-mannan and β-d-glucan, which have significant properties due to their interaction with the immune system of the host (5).
It is a source of iron and selenium which helps prevent deficiency of these minerals. Selenium repairs cell damage, and aids zinc in tissue repair, wound healing, and helps maintain our sense of taste and smell (6).
Studies have found Saccharomyces Cerevisiae to protect intestinal barrier integrity (7) and strengthen epithelial barrier function (8).
