How Can I Protect My Gut Microbiome When on Antibiotics?

Sometimes antibiotics are truly necessary and life-saving. They can clear bacterial infections, prevent complications, and support recovery when the body needs assistance. However, antibiotics do not distinguish between harmful bacteria and beneficial microbes. In eliminating the infection, they can also disrupt the healthy bacteria that support digestion, immune balance, and the integrity of the gut lining. This is why many people notice digestive shifts—like bloating or diarrhea—during or after a course of antibiotics.

One simple and well-studied way to support the gut during antibiotic therapy is with Saccharomyces boulardii, a beneficial probiotic yeast. Unlike bacterial probiotics, it is not destroyed by antibiotics, which means it can be taken at the same time. A typical adult dose is 5 billion CFU twice daily during the course of antibiotics (and often for 1–2 weeks afterward). Research shows it may help reduce antibiotic-associated diarrhea, support the intestinal barrier, and lower the risk of C. difficile infections by helping maintain microbial balance while the ecosystem is temporarily disrupted. As always, probiotic use should be individualized, particularly in immunocompromised individuals.

Supporting the microbiome while treating an infection is part of honoring the body’s terrain, not just eliminating symptoms. When antibiotics are necessary, thoughtful support with Saccharomyces boulardii can help preserve gut resilience and promote a smoother recovery.
