What is Saccharomyces boulardii?

Saccharomyces boulardii, or S. boulardii, is a probiotic which differs greatly from the well-known species such as L. acidophilus.  Saccharomyces boulardii is actually a probiotic yeast, originally extracted from the lychee fruit. 

It is a transient probiotic, meaning that it passes through the system without binding to the gut wall lining.  S. boulardii has undergone years of rigorous clinical research demonstrating its safety, and its ability to bind to and flush out pathogens such as E. coli and Salmonella; thereby naturally working against diarrhoea.  In fact, research on Saccharomyces boulardii is so extensive, that this strain is registered as a medicine in over 100 countries.  S. boulardii  has also been shown to have considerable anti-inflammatory properties, helping to maintain gut health in those with Inflammatory Bowel Disease or Irritable Bowel Syndrome.  It has furthermore been shown to help clear overgrowth of pathogenic yeasts such as Candida albicans.

The name 

Saccharomyces boulardii lends its name to the French scientist, Henri Boulard, who discovered the probiotic yeast in 1923 in South East Asia where he noticed people using the skin of lychee fruit for its beneficial health properties.  S. boulardii is often referred to as S. boulardii lyo, where the 'lyo' is short for 'lyophilisation' - a form of freeze-drying which S. boulardii normally undergoes in its supplement form. This process allows the supplement to be shelf-stable so that refrigeration is not necessary.  OptiBac Probiotics For bowel calm is lyophilised.
