What Is Florastor®?
Florastor is an all-in-1 probiotic that offers many benefits for your microbiota. It is the only probiotic containing the yeast Saccharomyces boulardii CNCM I-745, a unique probiotic strain studied in over 100 clinical trials and researched worldwide for over 65 years.
A century of improving health with probiotics
While traveling in Indochina in the early 1920s, Henri Boulard, a French microbiologist, noticed the locals drinking a special tea—made from lychee and mangosteen—to help with digestion. Fascinated by the healing properties of these two tropical fruits, Boulard conducted further research and discovered the active ingredient, a yeast, to be what he later called Saccharomyces boulardii.
S. boulardii was first introduced to the market in 1953 by the French pharmaceutical company, Biocodex. Since then, it has become available in over 100 countries making it the #1 probiotic worldwide.¹⁶
What Makes Florastor® Unique?

Antibiotic Associated diarrhea
Antibiotics can kill bad but also good bacteria found in the gut and dramatically change your gut, leading to long term gut disturbances, an unbalanced gut flora called dysbiosis.
Diarrhea is a common side effect of antibiotic use, signalling a warning from your gut.
