    • Initial use: Take 1 sachet (and up to 4 sachets if required) daily with food.
    • Ongoing use: 1 sachet will often suffice but more can be taken as desired or as professionally directed.
    • 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, after a particularly bad flare up of IBS. 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 and I without noticing my IBS settling down. I recently ran out of my supply so whilst I waited for them to be delivered I noticed a huge difference in pain, BM frequency, digestion and all of the other symptoms that come with IBS. 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. Was very constipated and decided to try them only took one a day after a few days nothing!! 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 power 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!!!!
