Saccharomyces boulardii is a viable yeast that is genetically different from Baker's yeast, and does not contain milk components. S. boulardii is a true biotic, or living organism, which has been shown to have beneficial effects by improving intestinal microbalance when administered in adequate amounts. S. boulardii is not part of the naturally occurring gut flora, and is not significantly impacted by antibiotics. Oral administration achieves steady state concentrations in the colon within three days, but does not colonize in the intestinal tract. The organism is typically cleared from the intestinal tract within 2 to 5 days after discontinuation. Each capsule supplies 235 mg of Saccharomyces boulardii, providing a minimum of 4 billion organisms at the time of manufacture.
