A study financed by the U.S pharmaceutical company Biocodex, investigated the effects of Saccharomyces boulardii (a probiotic yeast), and a commonly prescribed antibiotic Am***cillin/Clavulanate, on the microbiome of the healthy human digestive tract.
Saccharomyces boulardii is a probiotic yeast, found naturally on the skin of lychee fruits
The particular substrain used in this study was Saccharomyces boulardii CNCM 1-745. The study carried out by Dr Kelly, a Professor of medicine at Harvard Medical School, and Dr. Kabbani a gastroenterology fellow at Beth Israel Deaconess Medical Center concluded that; commonly prescribed antibiotics, such as Am***cillin, indiscriminately wipe out both friendly and unfriendly bacteria from the gut, and have a negative impact on the microbiome and therefore our health.
However, when patients were given Saccharomyces boulardii alongside a course of antibiotics, the study showed that the populations of good and bad bacteria in the GI tract were kept in a healthy balance.
The Executive Vice President of Biocodex, Marc Rohman, stated that: ‘These findings demonstrate that this probiotic yeast, now proven to preserve gut flora balance, even when an antibiotic is on board, can significantly contribute to preventative health care’.
