This is a high quality, short term course of live cultures. 'One week flat' from OptiBac is gluten free and therefore may be especially suitable for those with bloating.

  • I have just tried the One week flat and it was great for me. I have IBS-C and have been advised to take probiotics. I've tried other but none of them were as great as this one.
    I am also trying a different OptiBac product and I have high hopes.
    Massive thank you to Kerry for her assistance and time responding to my enquiry.

  • After taking a long course of strong anti-inflammatory medication for a back problem and eating too many rich foods over Christmas, my tummy was so bloated and painful, especially at night.
    These sachets have made a huge difference to me, my tummy feels back to normal now. They really helped.

  • The first sachet I took I didn't feel a lot of difference. My stomach always looked huge. I suffered with IBS and bloating. Stopped taking it.
    Then I found I felt worse.
    I then ordered 4packs. This then worked. Bloating has gone. Stomach a lot smaller. I stopped looking like a pregant woman at 72.
    Now having once a month.

  • I bought this to try & get rid of my bloating around the time of the month. It was ok and did work quite well. The main difference I noticed was how my constant indigestion caused by a gall stone has eased off. I've bought another pack to see if gets even better.

  • First of all I am sorry because English is my second language.
    I have tried all types of probiotics here in California, but none of them do me any good. But a problem with bloating, constipation. I keep searching for more brands, finally I have found Optibac One week flat that solved all the problem from all brands I have been taking.

  • Omg!!! Saving my insides - only 2 days in! I'd been on painkillers for nearly a fortnight due to dental pain, and was so bloated and felt horrible for it. So taking these and on my 2nd day I feel so much better and the bloat I had is down almost by half already. Will defs be repurchasing and having this on hand for future such emergencies, and also starting the everyday as I do suffer with water retention and irregular bowels sometimes!

  • I bought this product because I was suffering from severe bloating after taking another probiotic product. I do suffer from IBS but never was bloated. My IBS is mostly cramping with diarrhea. After taking the other product I was severely bloated and now was constipated. And the problem was not temporary, and has been ongoing since December 2015. After seven days on this product my bloating was a lot less and I went back to IBS-D with minor bloating. So I would recommend this product and I have ordered a second box. I also going to try the daily probiotic. Sometimes your digestion system may take some time to fix. As in my case.

  • Saw plenty of positive reviews on this products and decided to give it a shot as I have been suffering from bulimia bloating. However I was greatly disappointed as it has done practically nothing for me, I feel and look the same. I would not purchase this ever again.

  • I've been using these since for at least two years and have repeat purchased on multiple occasions. I find them great the morning after a heavy meal to depress that bloated feeling without using anything too pharmaceutical. They're also great (like the other products) for when you're taking antibiotics to help keep that balance. Overall, would recommend.

  • I took the seven day course and my bloating disappeared, however I got constipated and I had to take laxatives. Therefore I am not buying this product again.
