What it is

Saccharomyces Cerevisiae (Boulardii) is a probiotic & yeast supplement. Saccharomyces cerevisiae var. boulardii is a probiotic yeast (the species behind 'S. boulardii') robust to antibiotics and stomach acid.

How it works

As a yeast it resists antibiotics, neutralises bacterial toxins, secretes proteases against C. difficile toxin and boosts secretory IgA, protecting the gut during disruption. Effects are dose-dependent and typically measurable within days for acute use.
