Brought down the bloating massively. Impressed!
Honestly amazing. My stomach was bloated for quite some time. I had on and off heartburn. Just generally felt rubbish. I bought these because of some of the reviews. They were amazing. I think I had gas stick in my stomach as my tummy was bloated up 2 clothes sizes. By the end of the week, the difference was amazing. I do still have the on and off heartburn but my stomach issue has been sorted. Will take this every 6 weeks to keep on top of everything or just keep a box on stand by. There is practically no flavour at all, a bit like potato starch. Drank it to problem. It doesn't always dissolve but it does work, so not fussed about that really. 5 stars for sure. I lost 2 kgs but unsure if it was to do with stored gas etc but was pleased anyway. Tgat was 6 weeks ago and gas stayed off. My friend tried it for meno belly and was also pleasantly surprised after telling me it was probably rubbish. Shebus very happy. I think the stomach needs a prebiotic/prebiotic from time to time to align it. If in doubt, definitely give it a go.

Brilliant product which works
Brilliant product. I have gallstones so I deal with a lot of bloating, after a massive weight loss last year my stomach is one area of my body Iโm most self conscious about and I was struggling with the area of my body Iโm most self conscious about sticking out so I thought Iโd try these. As Iโm only on day 2 itโs still early days but i definitely feel less bloated after meals Iโve noticed, will see how I get on with the rest of the week but now considering taking these daily.

A miracle
This is obviously a product which works for some but not for others. About 5 years ago, for no obvious reason my waist shot up by several inches and coping with things like waistbands and tights was nigh impossible. Two or three months ago a dietician immediately diagnosed 'bloating' and suggested I try One Week Flat. The result was astonishing. Within that first week I was back to normal and able once again to get into some of my own clothes which I was close to discarding. And tights are no longer a problem. I am using it one week on, two weeks off. I am unaware of any side effects. But it is important to acknowledge that it really doesn't work for everybody. I would just say, if you have a bloating problem try it.

Didnโt work well for me
Reduced my bloat slightly on the first day but overall I donโt think it did much for me and if anything it made my stomach quite upset

Does the job
Definitely settled bloat on my stomach area within a couple of days, I had been suffering with bloating after lots of poor food choices and it wasnt going away but this helped a lot.

Fantastic at helping your body form a natural rhythm
This has worked wonders on my tummy, tried every product over the years but this has been brilliant for bringing a regular daily flow in the output department! No cramping, no excessive trips to the toilet, just right. Am goi g to start using on a regular basis it has been that good for the last week. Highly, highly recommend
