    • I was living with serious bloating when I discovered One Week Flat. I use it regularly now and that bloating no longer happens! I no longer live in England, but I was delighted to find that I could buy it locally. (EU)

      Dorian - 14th June 2021

    • I have used these on and off when required for years now they are a holy grail supplement when it comes to debloating my awful endometriosis belly! If ever I have a an event like a wedding / or holiday ( or if I am having a bad month with my endo) I take for a week before and it works everytime my bloat is massively reduced alongside that horrible uncomfortable bloated feeling. I 100% reccomend :)

      Georgie - 10th April 2021

    • Find they are very difficult to dissolve, no matter how much you vigorously swirl
