Complete your selection
Saccharomyces Boulardii is a supplement containing a non-pathogenic yeast resistant to stomach acids and proteolysis.
The concept of incorporating microorganisms into the human diet dates back several thousand years: today, traditional fermented milks and supplements containing live microorganisms are consumed all over the world by people keen to improve their health.
What exactly is the yeast Saccharomyces Boulardii?
Saccharomyces boulardii is a natural-source yeast, first isolated from lychee and mangosteen peel by the French microbiologist Henri Boulard at the beginning of the 20th century. It is now sold in almost 200 countries under various brand names, the best-known being ‘Ultra Levure’.
A healthy gut microbiota is a “complex, balanced collection of microorganisms which normally live in the gastrointestinal (GI) tract and which fulfil a role in the host’s nutrition, physiology and immune system control” (1). Environmental factors (smoking, antibiotics, intense stress, poor diet) can upset the balance of this flora, potentially allowing certain pathogenic bacteria to spread and cause damage.
Though not naturally present in human microbial flora, Saccharomyces Boulardii is able to grow there. It can rapidly reach high concentrations in the GI tract and remain there for several days. Once supplementation stops, Saccharomyces boulardii is gradually eliminated within 2 to 4 days in stools (2).
How does it act in the body?
Saccharomyces Boulardii is able to synthesise proteins in response to the various types of stress it encounters, in order to adapt to its environment. Stomach acids encourage it, in particular, to produce heat shock proteins (3) and various factors (more than 1500 have been identified) able to influence certain of the body’s functions and correlated with various mechanisms of action (Buts & De Keyser, 2006).
Five good reasons to choose the supplement Saccharomyces Boulardii
- It survives stomach acidity (because of its optimal pH of between 4.5 and 6.5) and proteolysis (digestion of food) very well (4).
- It can be taken at the same time as antibiotics because, as a yeast microbe, it is resistant to them.
- Its optimal temperature of 37° C enables it to survive in the body, unlike its related strain Saccharomyces cerevisiae (5).
- It contains 20 billion CFU (the unit used to estimate the amount of viable fungal cells) per dose.
- It contains no synthetic additives – likely to upset the microflora – which is not the case for most Saccharomyces Boulardii supplements and medicines.
What is in Saccharomyces Boulardii
Any questions?
Antibiotics are sometimes necessary to treat a bacterial infection. However, they upset the balance of gut flora because they also destroy or block the growth of beneficial bacteria. As a result, there is normally a significant decrease in the proportion of Clostridium bacteria in the tract following a course of antibiotics (6).
There are many definitions of the word probiotic. This is the one used by the UN Food and Agriculture Organization (FAO) in 2002, and adopted by the World Health Organization (WHO): “a probiotic is a live microorganism (also called bacteria or yeast) which, when administered in adequate amounts, confers a health benefit on the host, beyond traditional nutritional effects”.

Are there any precautions attached to taking Saccharomyces Boulardii supplements?
Saccharomyces Boulardii supplementation is is not recommended for pregnant women, those who are immune-deficient or seriously ill, and those with a central venous catheter (slight risk of fungemia).
We recommend a dose of 2 capsules before lunch and 2 before dinner if you’re taking antibiotics, are travelling to a tropical country or are suffering from acute diarrhoea. The period of supplementation can range from 5 to 30 days, depending on your symptoms.
In the case of diarrhoea, we recommend adopting the following measures alongside your Saccharomyces Boulardii supplementation:
- Make sure you stay well-hydrated (drink at least 2 litres of water a day) ;
- Don’t eat crudités, fruit, green vegetables, spicy dishes or frozen foods;
- Focus on grilled meats and rice.

This product’s capsules are made of pullulan, a natural polysaccharide obtained by fermenting tapioca or corn. Pullulan contains no animal ingredients and provides an excellent barrier to oxygen, helping to preserve the integrity of the capsule’s ingredients. It is also an eco-friendly alternative to synthetic materials.
