During the 1920's a biochemist, Henri Boulard, was living in French Indochina. He noticed that the local people were scrapping a substance off the skin of Lychee Nuts and Mangosteens and making a homemade remedy for digestive upset. Intrigued, Dr Boulard examined the substance in his laboratory and discovered that it was a yeast. In recognition of his discovery this Saccharomyces yeast was named after him, Saccharomyces boulardii.
When Dr Boulard returned to France, he brought the yeast culture with him. For the next 30 years he tested its use as a stomach remedy and in the mid 1950’s he sold this discovery to a French pharmacist who was able to create a commercialized product in France.
From that first discovery, Saccharomyces boulardii is now used in over 80 countries around the world. It is the first beneficial yeast probiotic. Other probiotics are all bacterial. This is significant when taking antibiotics because yeast probiotics are not affected by antibiotics. When used according to labeled directions StableGI® brand of Saccharomyces boulardii is safe for anyone older then 2 months of age.
