Saccharomyces boulardii is a unique, non-pathogenic probiotic yeast known for its powerful ability to support gut health, restore digestive balance, and protect against intestinal disturbances. Unlike bacterial probiotics, this yeast-based strain is particularly resistant to antibiotics, making it ideal for use during and after antibiotic treatment.

Originally discovered in the 1920s by French scientist Henri Boulard, who isolated the strain from tropical fruit skins during a cholera outbreak in Southeast Asia, S. boulardii has since become one of the most clinically studied probiotic yeasts in the world.

The Benefits of Saccharomyces boulardii

Saccharomyces boulardii offers a range of well-documented health benefits, particularly in the management of gastrointestinal conditions. Its primary benefits include:

• Supporting digestive balance during and after antibiotic use

• Preventing and reducing diarrhoea, including antibiotic-associated, traveller’s, and infectious diarrhoea

• Helping restore the intestinal lining and reducing inflammation in the gut

• Providing resistance to harmful bacteria and toxins

• Supporting gut flora without being destroyed by antibiotics

Because it's a yeast rather than a bacterium, S. boulardii can be used alongside standard probiotics like Lactobacillus acidophilus or Bifidobacterium longum without interference.
