Saccharomyces boulardii is a non-colonising lactic acid
producing yeast. It checks or treats antibiotic-associated
diarrhoea, C. difficile related disorders, acute diarrhoea,
traveller’s diarrhoea in tube-fed patients. They are also
beneficial in AIDS-associated diarrhoea and in preventing
relapse of Crohn’s disease. Most eminent feature is that
they secrete proteases and other substances that
breakdown bacterial enterotoxins and hinder their
binding to intestinal receptors. They also help in
enhancement of immune function. Most of the beneficial
species enhance vitamin production and decrease serum
cholesterol levels and have a role in anticarcinogenic
