Bioglan Medlab SB 5B (Saccharomyces cerevisiae) 60vc




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; by increasing the production of secretory IgA (sIgA), short-chain fatty acids (SCFAs) and helping to promote the activity of brush border disaccharide enzymes. SB has demonstrated efficacy in relieving diarrhoea severity and duration in both adults and children due to various triggers. SB assists in supporting healthy immune function and may help to reduce inflammatory mediators in the gastrointestinal tract.

  • If diarrhoea persists for more than 6 hours in infants under 6 months, 12 hours in children under 3 years, 24 hours in children aged 3-6 years or 48 hours in adults and children over 6 years, seek medical advice.
  • If symptoms persist consult your healthcare practitioner.


SB has shown to be well tolerated in adults when taken orally for up to 15 month’s duration. It can cause flatulence in some people. Infrequent cases of fungaemia have been reported in case reports but only in patients with serious diseases in which they have been hospitalised. SB has shown to be well tolerated in children when taken orally appropriately. However, a healthcare practitioner should evaluate diarrhoea in children before using SB 5B™.


Medications for fungal infections (i.e. dicflonac) interact with and reduce the therapeutic effectiveness of SB due to SB being a yeast.
