    Customer Questions

    All questions answered by probiotic experts Dr Kate Steed PhD (Food and Microbial Sciences) BSc(Hons) Medical Biology and Helen Morton BSc (Hons) DipION Nutritional Therapist

    Yes! In fact, it’s highly recommended. S. boulardii does not colonise for long in the gut but it harmonises extremely well with all types of friendly bacteria, so most people take them in combination.

    Research shows that the friendly yeast Saccharomyces Boulardii is suitable to take alongside antibiotic medication1. This has also been mentioned in a ZOE podcast. 

    Our gut microbiomes are unique, so the response to Saccharomyces boulardii varies. If taking Optibac S. Boulardii supplement, each capsule contains 5 billion live cultures. Try 1-2 capsules initially (or a stronger 3-4 capsules together if desired) and increase if necessary up to a maximum of 6 capsules (30 billion live cultures) spread over the day. Within these guidelines, then take as much or as little as you need, on an occasional or ongoing basis.

    Saccharomyces boulardii is one of the most highly researched strains in the world! But it’s actually a friendly yeast, not a type of bacteria. This internationally acclaimed strain has been used safely1,2 for over 50 years around the world, but it was Optibac that first introduced a Saccharomyces boulardii supplement to the UK.

    It’s easy to take S. boulardii live cultures – they can be taken at any time of day, with or without food! This friendly yeast is more robust than most bacteria1, and can resist high heat, humidity, and stomach acid levels. It doesn’t need refrigeration, so you can take it with you, wherever you go!

    Read references

    As a friendly yeast, Saccharomyces boulardii is hardier than most good bacteria. It survives well in very hot or humid conditions1, doesn’t require refrigeration and can be taken with or without food. It’s the perfect ‘friend’ to take on your worldwide travels!
