Saccharomyces Boulardii

Saccharomyces boulardii is a beneficial probiotic yeast, first discovered in the 1920s by French microbiologist Henri Boulard. Since its discovery, over 250 peer-reviewed studies have been conducted, making it one of the most extensively researched probiotics available. Unlike Saccharomyces cerevisiae, or "brewer’s yeast," S. boulardii is a non-pathogenic yeast with distinct properties that support gastrointestinal and immune health.

S. boulardii has been shown to enhance secretory IgA (sIgA) levels, a key immunoglobulin found in the digestive tract and mucosal secretions. sIgA plays a vital role in immune defense by binding to and neutralizing foreign substances in the gut, protecting against unwanted agents. Maintaining healthy sIgA levels is essential for immune health, particularly for those with low immune response, food intolerances, or dysbiosis—a condition where beneficial gut bacteria are outnumbered by less desirable species. Additionally, S. boulardii supports gastrointestinal health by competing with harmful organisms for space and nutrients.

To function effectively as a probiotic, microorganisms must survive the body’s natural defenses, including stomach acid and high temperatures. This advanced formulation of S. boulardii is stomach acid-resistant, freeze-dried, lactose-free, and genetically verified for strain purity and efficacy. It is specifically designed to deliver maximum probiotic support by ensuring survival through gastrointestinal transit and into the intestines.

Take 1 capsule twice daily, or as directed by your healthcare professional.
