Product Description

Optibac One week flat is an easy-to-take, 7-day probiotic course, providing 5 billion live microorganisms and 0.3g FOS fibres (Fructooligosaccharides) per sachet.

This multistrain supplement has been created especially for bloating symptoms, and contains four high-quality strains: Bifidobacterium bifidum Rosell-71, Lactobacillus casei Rosell-215, Lactococcus lactis Rosell-1058, and the world-renowned Lactobacillus acidophilus Rosell-52. These premium probiotic strains are well-researched, proven to reach the gut alive, and to adhere to the gut wall. They help to reduce bloating by inhibiting the harmful pathogens which can cause gas, and by helping with the digestion of problematic foods. The FOS fibres further help to support bloating symptoms by encouraging the growth of good bacteria, optimising bowel regularity.

This probiotic course is designed to be taken for 7 consecutive days, with breakfast for best results. Contents can added to cool, non-acidic foods or drinks. Each pack contains 7 sachets.

This safe, natural vegetarian supplement is free from GMOs and gluten. It is safe for use by all from the age of 4 years, including pregnant & breastfeeding women.

Unlike many products containing live cultures, this supplement does not require refrigeration if stored in a cool dry place below 77oF (25°C). All OptiBac Probiotics strains are thoroughly researched and tested, and our probiotic supplements undergo rigorous quality control and safety checks conducted by some of the world’s leading microbiology institutes, so you can be confident you're buying a supplement of the highest quality.

  • Continue to take for seven consecutive days, or as professionally directed.


Store in a cool dry place and avoid exposure to humid conditions. Live cultures should be mixed with cold, non-acidic food and drink only, as heat and acidity can damage the bacteria.
