OptiBac Probiotics 'Saccharomyces boulardii' has been created especially for those seeking a natural option. It contains 5 billion pure live cultures of the internationally acclaimed Saccharomyces boulardii, with no additives nor fillers. This well-researched and unique strain has been used safely around the world for over 50 years. Suggested for daily use, each capsule provides 5 billion live microorganisms guaranteed, and it's proven to survive through stomach acidity and reach the gut alive. This supplement does not interfere with medicines or supplements for Candida, IBS or diarrhoea.

The strain within OptiBac Probiotics 'Saccharomyces boulardii' is extremely well-researched. Each pack contains 80 capsules.

This supplement, unlike many products containing live cultures, does not require refrigeration. This is thanks to improvements in freeze drying techniques, as well as the S. boulardii strain being naturally robust and able to survive harsher conditions. All OptiBac Probiotics strains are thoroughly researched and documented, so you can be confident you're getting a high quality supplement, which is right for you.


Adults: take one to four capsules initially, and depending on severity of symptoms take up to six capsules daily; or as professionally directed.

Children (one year and over): take in smaller doses

For children the dosage can be lowered. For anyone unable to swallow capsules, the capsule can be opened and the contents mixed with cold food or drink. 

Safety Warnings

Do not exceed recommended daily dosage. Food supplements should not be used as a substitute for a healthy diet and lifestyle. Pregnant or breastfeeding women, or those with serious medical conditions, should consult their doctor before use.

OptiBac Probiotics may be used on an ongoing basis and can safely be used on either an occasional or daily basis, depending on reasons for use.

    Use this to keep bouts of diarrhoea at bay. Nice product - bringing good bacteria to gut and usually my stomach clears up within a day.

    Effective product and efficient service from Blukoo.
    Prefer blister packs to screw top container for ease of use.

    I was surprised when my recent order arrived in a plastic screw top container instead of the usual packet with foil strips.
    Whilst the product is still effective, I prefer the strips as they are easier to take away on holiday.
