This high quality supplement from OptiBac Probiotics offers you a natural option, which can be safely taken alongside medicines or supplements for diarrhoea, IBS or Candida. Accharomyces boulardii is a highly researched, natural and safe yeast with different properties and actions to other yeasts. OptiBac Probiotics was the first company to introduce Saccharomyces boulardii to the UK. Having an imbalance of good and bad bacteria in the gut may be associated with various digestive health conditions such as diarrhoea, Candida, IBS & IBD. This microorganism is more robust to environmental stressors than more common bacterial live cultures, and shows strong resistance to heat, humidity and stomach acidity levels. These live cultures of Saccharomyces boulardii from OptiBac Probiotics have been tested and shown to be especially stable and resistant. Saccharomyces boulardii is a natural food supplement and not a medicine. Choose OptiBac Probiotics Saccharomyces boulardii if you want a quality supplement containing the internationally acclaimed and highly researched S. boulardii.
