    Customer Questions

    All questions answered by probiotic experts Dr Kate Stephens PhD (Food and Microbial Sciences) BSc(Hons) Medical Microbiology and Kerry Beeson BSc (Nut. Med.) Nutritional Therapist.

    Is Saccharomyces boulardii a friendly bacteria strain?

    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.

    How much S boulardii should I take? 

    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.

    What is the best time to take S. boulardii?

    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 bacteria, and can resist high heat, humidity, and stomach acid levels4. It doesn’t need refrigeration, so you can take it with you, wherever you go!

    Can S.boulardii be taken with other live cultures?

    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.

    What makes Saccharomyces Boulardii suitable for travel?

    As a friendly yeast, Saccharomyces boulardii is hardier than most good bacteria. It survives well in very hot or humid conditions4, doesn’t require refrigeration and can be taken with or without food. It’s the perfect ‘friend’ to take on your worldwide travels!  

    Safety

    Live cultures are not recommended for those with serious medical conditions e.g. those who are severely immunosuppressed, have pancreatitis, are in the ICU, have melaena, have a central venous catheter, short bowel syndrome, or patients with open wounds following major surgery; unless under a doctor's care. Keep out of reach of children.

    This is a food supplement and is not intended to prevent, treat or diagnose any medical conditions. Probiotic supplements should not be used as a substitute for a healthy diet and lifestyle. If you are taking any medications or have a serious medical condition, consult a doctor before use. Optibac supplements will not cause dependency and may be used on an ongoing basis.

    Pregnant or breastfeeding women should consult their doctor before taking Saccharomyces boulardii.

    • Absolutely love this product. Use it regularly with many of my clients. Also like to combine with 'for when on antibiotics'. Highly recommend many of Optibac products.

      Nicola Warran - 29th June 2022

    • I have tried other probiotics but I have found Optibac S. Boulardii suits me very well and I can tell the effect even on the improvement in my skin. Customer service couldn’t have been more courteous and helpful when I emailed about a question I had.
