Saccharomyces boulardii is a beneficial probiotic yeast recognized for its ability to support gastrointestinal health and immune function.
Unlike traditional bacterial probiotics, S. boulardii is naturally resistant to stomach acid and high temperatures, ensuring it survives transit through the digestive system to reach the intestines. Once there, it helps restore microbial balance, enhances the integrity of the gut barrier, and supports the body’s natural defenses.
Backed by more than 250 peer-reviewed studies and over 50 clinical trials, Saccharomyces boulardii has been shown to boost levels of secretory IgA (sIgA). This vital antibody plays a key role in immune protection within the digestive tract.
By promoting healthy intestinal barrier function, competing with unwanted microbes, and supporting balanced immune activity, S. boulardii offers comprehensive gastrointestinal support.
This formula is freeze-dried, lactose-free, and genetically verified for quality and potency, making it a reliable option for daily gut and immune wellness.
Take 1 capsule twice daily, or as recommended by your healthcare professional.
