Florastor works by:

• Introducing Saccharomyces boulardii, a beneficial yeast, into the gut
  
  
• Competing with harmful bacteria and yeast that cause infections or digestive problems
  
  
• Supporting the gut’s natural defense system and immune response
  
  
• Helping restore balance in the gut flora after disruption from antibiotics, illness, or poor diet
  
  
• Producing substances that inhibit harmful microbes
  
  

This unique probiotic yeast is resistant to antibiotics, so it can be taken alongside them to help prevent antibiotic-associated diarrhea.
