Saccharomyces boulardii - restore gut microbiota balance
Saccharomyces boulardii 250 mg is a probiotic yeast capsule that supports digestive system health and the balance of gut microbiota. Each capsule provides 250 mg of probiotic dry mass of Saccharomyces boulardii, offering a convenient form of supplementation.
What is Saccharomyces boulardii?
It is a unique yeast strain classified as a probiotic, meaning it exerts a beneficial effect on the host’s health. Unlike most probiotic bacteria, S. boulardii is a live organism that acts temporarily in the gastrointestinal tract without permanently colonising it. Its key role is to support the intestinal barrier, modulate the immune response and effectively compete with pathogens, which makes it particularly effective in preventing and alleviating diarrhoea (especially antibiotic-associated and travellers’).

Supports gut microbiota balance and intestinal barrier integrity:
Helps maintain a proper set of microorganisms in the intestines and may support a healthy mucosal response.
Protective action against antibiotic-associated diarrhoea (AAD):
May reduce the incidence of diarrhoea after antibiotic therapy and support gastrointestinal comfort during treatment.
Supports the management of acute infectious diarrhoea:
Studies suggest a reduction in the duration of diarrhoea and the number of bowel movements, especially in children and adults. Helps in the prevention and alleviation of travellers’ diarrhoea. May reduce the risk of symptoms during travel and lessen their severity.
Influences the mucosal immune response of the intestines:
May modulate the local immune response (e.g., impact on the production of immunoglobulin A in the intestines) and support the body’s protective barriers.
Antimicrobial action through antagonism mechanisms:
By competing for adhesion sites and producing factors that hinder pathogen colonisation in the intestines. Neutralises toxins and limits pathogen activity (relatively confirmed in laboratory studies). Some studies suggest the possibility of partially neutralising bacterial toxins (e.g., C. difficile toxins) and inhibiting pathogen adhesion to the mucosa.
Supports convalescence after disturbances of intestinal function:
May support a return to normal bowel function after periods of intestinal stress, illness or antibiotic therapy.
Potential effect on reducing intestinal inflammation:
There are reports of cytokine modulation (e.g., lowering pro-inflammatory mediators), although mechanisms and effects depend on many clinical factors.
Supplementation of the daily diet in certain health situations:
May be used as an element supporting digestive health during stress, dietary changes or travel, but does not replace medical treatment.
The probiotic has undergone careful studies confirming its top quality.
High-quality Saccharomyces boulardii with confirmed activity of 26 billion CFU/g and microbiological purity confirmed by laboratory testing.

Who is Saccharomyces boulardii for? Discover the benefits for yourself:
Adults and adolescents over 4 years of age (as per doctor’s advice or the enclosed leaflet) seeking support for gut health.
People taking antibiotics who want to help maintain gut microbiota balance.

105 ItemsAdditional information
Directions for use: The usual recommended dose is 1 capsule 1–2 times daily with water.
If needed (e.g., during antibiotic therapy) use according to the manufacturer’s or doctor’s guidelines, continuing for an additional period after finishing antibiotics. Follow the on-pack instructions and do not exceed the recommended dose without consulting a doctor. The product is intended for adults and adolescents over 4 years of age (always according to the manufacturer’s recommendations).
FAQ
How does Saccharomyces boulardii stand out from other probiotics?
Saccharomyces boulardii is a yeast, not a bacterium—this is a fundamental difference that accounts for its natural resistance to antibiotics and its ability to be used concurrently with antibiotic therapy, which cannot be said of most bacterial probiotics. Unlike many bacterial strains, it does not permanently colonize the intestines but passes through the digestive tract, exerting an effect on it; therefore, the effects depend on the regularity of intake. Additionally, it is relatively well tolerated and may be considered by people who cannot tolerate certain bacterial probiotics, although any supplementation should be tailored to individual needs and discussed with a doctor.
When should you consider taking supplements?
Saccharomyces boulardii is often considered primarily during and immediately after a course of antibiotic therapy, as it can help restore the balance of the gut microbiota after it has been disrupted. Other situations in which many people turn to this strain include travel to countries with different sanitary conditions, periods of increased stress, and changes in dietary habits. It is advisable to take it regularly and according to the label instructions; for long-term supplementation or in cases of comorbidities, consult a doctor.
