Practitioner product


SB 5B is an evidence-based probiotic yeast that provides targeted support for healthy immune function and diarrhoeal illness.

Saccharomyces cerevisiae ssp. boulardii (SB) is a beneficial probiotic yeast that helps to maintain gastrointestinal function and integrity by supporting a healthy gut microbial profile; increasing the production of secretory IgA (sIgA), short-chain fatty acids and the activity of brush border disaccharide digestive enzymes. SB has demonstrated clinical efficacy in relieving diarrhoea severity and duration due to various triggers in both children and adults and may be used to support symptoms of infectious, antibiotic-associated or traveller’s diarrhoea. SB supports immune function with a predominant anti-inflammatory effect and also neutralises bacterial toxins along the gastrointestinal tract.
