Description & Details


  • INTERNATIONALLY ACCLAIMED – Optibac Saccharomyces boulardii contains the well-researched, internationally acclaimed strain of friendly yeast Saccharomyces boulardii which has been used safely for over 50 years. It is more robust to environmental stressors than common bacterial live cultures and is especially stable and resistant to heat and humidity. This supplement contains a guaranteed 5 billion live microorganisms per capsule, guaranteed until end of expiry.
  • HIGHLY RESEARCHED – Unlike many live cultures supplements on the market, this pure Saccharomyces boulardii supplement has been extensively researched in numerous clinical trials worldwide. It has been scientifically proven to pass through stomach acidity and survive to reach the gut alive.
  • NATURAL & VEGANE – This supplement contains natural live cultures. It is suitable for vegans, and like the rest of the range is gluten-free for those with coeliac disease or an intolerance. This product is also free from added sugars, artificial flavourings or colourings.
  • EASY TO TAKE & FRIDGE-FREE – Simply take 1-4 capsules a day, or up to 6 as professionally directed. If you prefer, capsules can also be opened and the contents sprinkled over cold, non-acidic foods and drinks. Optibac live cultures capsules do not need a special protective coating (the quality is in the strains themselves) and none of the range requires refrigeration, making them shelf-stable – so you can keep them on your desk, in your handbag, wherever you won't forget them!
  • CARING COMPANY – We specialise entirely in friendly bacteria, offering specific strains for your individual needs. We've spent nearly 2 decades working with the most researched strains in the world and use these to formulate our wide range. With an ‘excellent' rating for both our products & customer service, we're proud to be the UK's most recommended brand of friendly bacteria supplements.
