Your gut serves as a control centre for digestion, immunity, and overall well-being. When it's in balance, you feel energised and resilient. However, factors such as travel, antibiotics, illness, or even everyday stress can disrupt that balance.
Saccharomyces boulardii is a unique probiotic yeast that helps restore harmony in your gut. Discovered over a century ago in tropical fruit, it is known for its ability to survive stomach acid, resist antibiotics, and support the growth of beneficial microbes.
Whether for daily wellness or during travel, S. boulardii offers a simple and effective way to keep your digestion—and overall health—on track.
What is Saccharomyces Boulardii?
Saccharomyces boulardii is a tropical yeast that was first identified in the early 1900s by French microbiologist Henri Boulard. It is found on the skins of lychee and mangosteen fruits and has been recognised for its ability to support digestive health.
Unlike the yeast commonly used in baking or brewing, S. boulardii thrives at body temperature and can survive stomach acid. Once it enters the gut, it temporarily helps to maintain a healthy balance of microorganisms and naturally exits the body a few days after supplementation is discontinued.
How Saccharomyces Boulardii Works
| Action | Benefit |
|---|---|
| Blocks harmful bacteria | Prevents pathogens from attaching to and damaging the gut lining. |
| Neutralises toxins | Produces enzymes that break down toxins, supporting a healthier gut environment. |
| Supports immunity | Helps regulate intestinal immune responses and reduce inflammation. |
| Encourages balance | Promotes beneficial bacteria while limiting harmful overgrowth. |
