Saccharomyces boulardii is one of the most studied and proven supplements on the market today. It has been shown to help prevent incidents of antibiotic associated diarrhea and traveler's diarrhea. It can be taken alongside a course of antibiotics, or after an event that has compromised gut health, to restore intestinal balance.

First discovered by the French scientist Henri Boulard almost 100 years ago, Saccharomyces boulardii is strain of non-pathogenic yeast that has been the subject of over 250 peer reviewed articles. As a probiotic yeast, S. Boulardii is often taken alongside a course of antibiotics, as the yeast will survive the treatment. This is why we named our S. boulardiiproduct Spartan Strain. Each capsule of Spartan Strain contains 5 billion colony forming units of the probiotic yeast. The formula is freeze dried for maximum potency, and does not need to be refrigerated.
