Decades-Old Science Behind Florastor
Back in 1923, French microbiologist Henri Boulard traveled across Southeast Asia. He noticed local people drinking brews made from mangosteen and lychee peels rarely suffered digestive upset.He isolated a special yeast strain from those fruit skins - later named Saccharomyces boulardii CNCM I-745.
This original strain was brought to market by Biocodex in 1953. In 1988, the authentic strain was preserved at Paris Pasteur Institute's CNCM culture bank. Florastor holds exclusive rights to this original strain, trusted across more than 100 countries for over 70 years.
