Frequently asked questions
- What is Saccharomyces boulardii?
- A probiotic yeast (not a bacterium) — used most commonly for digestive support, particularly during antibiotic courses or travel.
- What is MOS?
- Mannan-oligosaccharide — a prebiotic compound. Pairing S. boulardii with MOS combines a probiotic with a substrate it can feed on.
- Is the IGEN cert a banned-substance test?
- No — IGEN Non-GMO Tested verifies non-GMO sourcing only.
- Where can I buy it?
- Amazon UK at £35 is the listed retailer.
- How does this compare to bacterial probiotics?
- S. boulardii is a yeast, so it's unaffected by antibiotics that target bacteria — often the reason it's recommended during antibiotic treatment. Bacterial probiotics (Lactobacillus, Bifidobacterium and others) work via different mechanisms.
