Customer Questions
All questions answered by probiotic experts Dr. Kate Stephens PhD (Food and Microbial Sciences) BSc (Hons) Medical Microbiology and Kerry Beeson BSc (Nutritional Medicine) Nutritional Therapist.
Is One Week Flat suitable for both men and women?
Definitely! Friendly gut bacteria are not gender specific. This means that One Week Flat is suitable to be taken by everyone over the age of 4 years: women, men, and trans and non-binary people too!
How often should I take this friendly bacteria supplement?
It is recommended to take One Week Flat every day for at least one week. After that the rest is down to personal preference. One Week Flat can be used in the short term, as a week-long course for those who are looking for an affordable way to complement their natural gut bacteria every now and then. Equally, it can be used on an ongoing basis. There is no ‘right’ or ‘wrong’ way to take it. Here are some of the ways that our loyal One Week Flat customers take this supplement:
- a 7-day course regularly every month
- a 7-day course as and when desired
- one sachet every day on an ongoing basis
What does One Week Flat taste of?
One Week Flat has a fairly ‘neutral’ taste and most people find it easy and pleasant to take. You may notice a slight natural sweetness which comes from the Fructooligosaccharide (FOS) fibres, but you can rest assured that the supplement contains no added flavourings, sugar, or sweeteners.
I get bloated when I eat foods like dairy or gluten - can I take One Week Flat?
One Week Flat is gluten-free, so is fine to be taken by those with food-related bloating. It is also suitable to be taken by those with lactose intolerance1,2,3. This high-quality supplement contains 4 well-researched strains of friendly bacteria combined with 0.3g FOS fibres. Individual responses to a supplement can vary, but the majority of our customers get on well with this formulation, and purchase on a regular basis.
I'm on a calorie-restricted diet. Can I take One Week Flat?
One Week Flat contains just 7.72 calories per sachet, and 0g fat. Most of the carbohydrate in the supplement comes from the FOS fibres which are not digested, and therefore have almost no calorific content.

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)
-
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 belly! If ever I have a an event like a wedding / or holiday ( or if I am having a bad month) I take for a week before and it works everytime my bloat is massively reduced alongside that horrible uncomfortable bloated feeling. I 100% reccomend :)

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