    Now dispatching in our new look!

    We are introducing new, eco-conscious packaging this year, and the new designs will update gradually from product to product to minimise any waste. Please bear with us as you may receive orders with both current and new packaging over the coming months.  We hope you like the new look! 

    Update May 2021: This supplement was previously called OptiBac 'Bifidobacteria & fibre' in the EU and 'For maintaining regularity' in the rest of world. It's exactly the same great formula, which previously advertised 5 billion live cultures per sachet but has now been updated to 25 billion live cultures per sachet (based on latest stability data). Existing customers can continue to take it just as before!

    • It is strongly recommended to drink plenty of water with this supplement.
    • Shake the sachet, then slowly sprinkle contents into a glass of water and vigorously swirl to dissolve fully.

    • I have been taking these probiotics for a few months now. I have them in a smoothie every morning and sometimes on occasion give them a miss. They just became a part of my daily routine. I recently ran out of my supply so whilst I waited for them to be delivered I noticed a huge difference in frequency, digestion and other symptoms. I honestly never realised how much these probiotics help ease my symptoms and I would now be absolutely lost without them. They may not work for everyone but they are definitely worth a try if you’re all out of options. They were something I stumbled across when I was looking for my solution so definitely worth a try!

    • Oh my goodness these are amazing!! Have tried them before but only for a couple of days and stopped as they didn't work. But kept persevering and after about 6/7 days I went but just thought that would be it but I am still taking them and am going every single day now sometimes twice which is amazing considering that I only used to go once a week at the most. I have stopped taking laxatives now . If you keep on taking it you will definitely see results but I know for some people the time scale will be different.

    • This product is amazing. The cotton-candy taste of the powder reminds me of childhood :) The effect is even better!! My occasional bloating normalized just after one week and since then, I have not experienced such discomfort anymore! THANK YOU OptiBac!!!!
