Our History

In the early 1920s, Henri Boulard, a French agricultural engineer and microbiologist, traveled to Indochina in search of heat-resistant yeast that could be used during the fermentation process at a distillery.

He was there during a cholera outbreak and noticed that the locals drank a special tea – made from lychee and mangosteen skins – to help with digestion.

Fascinated by the healing properties of these two tropical fruits, Boulard conducted research and discovered the skins contained a special and unique yeast, which he later called Saccharomyces boulardii

Boulard recognized the potential of this yeast in the medical field and sold his patented strain to the French pharmaceutical company, Biocodex in 1953. Biocodex enhanced the strain’s fermentation process to elevate it to pharmaceutical quality, and registered with the Pasteur Institute in 1988 as Saccharomyces boulardii CNCM I-745 (S. boulardii lyo CNCM I-745).

S. boulardii lyo CNCM I-745 was the first yeast to be demonstrated to have probiotic properties and the first probiotic in human medicine. Since it’s discovery, S. boulardii lyo CNCM I-745 has been investigated in more than 600 clinical trials and has been available as a probiotic treatment for gut health for nearly 65 years!

Florastor® is the only probiotic in North America to contain S. boulardii lyo CNCM I- 745.
