The gut microbiota plays a critical role in maintaining digestive health, immune regulation, and protection against harmful microorganisms. While antibiotics are essential for treating bacterial infections, their use can disrupt the natural balance of gut microorganisms, reducing microbial diversity and weakening intestinal defense mechanisms. This imbalance may increase susceptibility to gastrointestinal disturbances, inflammation, and various long-term health complications. Restoring microbial balance has become an important consideration in gastrointestinal care. S. boulardii has been studied for its ability to support gut microbial health, help maintain intestinal integrity, reduce the risk of antibiotic-associated diarrhea, and improve symptoms and quality of life in individuals with irritable bowel syndrome.^[1][2]
