Things worth knowing about "Saccharomyces boulardii"

Saccharomyces boulardii is a dry yeast that is contained in medicines in freeze-dried form. Saccharomyces boulardii works exclusively in the intestine. There the probiotic active ingredient colonises the intestinal wall.

Saccharomyces boulardii is a probiotic yeastintestinal disorders, diarrhoea and antibiotic-associated dysbiosis. In contrast to classic probiotic bacteria such as Lactobacillus or Bifidobacterium, S. boulardii is a single-celled fungus, which is not part of the physiological intestinal floratemporarily colonises and develops a variety of health-promoting effects.

Particularly valuable is S. boulardii due to its ability to neutralise pathogenic bacteria and toxins, which stabilise the intestinal mucosa and inhibit inflammatory processes. Clinical studies have shown that the intake of S. boulardii significantly reduces the risk of traveller's diarrhoea, Clostridioides difficile recurrence and antibiotic-associated diarrhoea. The yeast strain also shows positive effects in chronic inflammatory bowel disease, irritable bowel syndrome, SIBO and in restoring the intestinal flora after antibiotic therapies.

Another advantage: As a yeast, S. boulardii is not sensitive to antibiotics, which makes it the ideal complementary probiotic during antibiotic treatments. It also promotes the secretion of immunoglobulin A (IgA), regulates proinflammatory cytokines and protects the intestinal mucosa by strengthening the tight junctions. In functional microbiome protocols, S. boulardii is often combined with other pro- and prebiotics to support holistic gut rehabilitation and immunomodulation.

Important characteristics of Saccharomyces boulardii:

  • Probiotic yeast with immunomodulatory properties

  • Resistant to antibiotics, ideal for dysbiosis and diarrhoea

  • Used for traveller's diarrhoea, antibiotic-associated complaints, SIBO, C. difficile

  • Supports the mucosal barrier, IgA production and cytokine regulation

  • Combinable with classical probiotics and micronutrients
