Is Saccharomyces boulardii a well-known friendly bacteria strain?

Saccharomyces boulardii is an internationally acclaimed strain; in fact, it is one of the most highly researched strains in the world! The unusual thing about it, however, is that it is actually a yeast, rather than a type of bacteria. Optibac first introduced Saccharomyces boulardii to the UK, but it has been used safely^1,2  for over 50 years in countries around the world and has been used in numerous clinical trials.

How many Saccharomyces Boulardii capsules should I take a day?

As we all have a unique gut microbiome, the response to Saccharomyces boulardii is different for each individual. You can take up to a maximum of 6 capsules per day, but it is recommended to start with 1-2 capsules per day and build up from there as required. When taking a higher number of capsules (3-6 capsules) it is advised to spread these across the course of the day, though if desired you can take 3-4 capsules together initially.

What time should I take Saccharomyces Boulardii?

There is no right or wrong time of the day to take Saccharomyces Boulardii, so whenever fits in with your schedule is fine. This strain of yeast is more robust to environmental stressors than more common bacterial live cultures, and shows strong resistance to heat, humidity, and stomach acidity levels. It doesn’t need to be refrigerated and can be taken with or without food.

Can I take Saccharomyces Boulardii alongside other friendly bacteria supplements?

Yes, it is fine to take Saccharomyces Boulardii alongside your other live cultures supplements, in fact it is recommended to do so. Saccharomyces Boulardii works differently to other friendly bacteria supplements because it is a ‘friendly yeast’³ and does not colonise for long in the gut, but it works well with other live cultures supplements, so most people take it alongside.

What makes Saccharomyces Boulardii suitable for travel?

Saccharomyces boulardii is a resilient strain of yeast which survives well in hot and humid conditions⁴, making it great for travelling. It doesn't need to be refrigerated meaning you can take it with you wherever you travel around the world.

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.

Customer reviews

• 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.

• 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.
