One Week Flat

Recommended use

Natural dietary supplement suitable for adults and children (from 4 years onwards) with the following recommendations:

• Take 1 sachet daily for 7 consecutive days, preferably with breakfast.
• Pour an inch of water into a tall glass, leaving plenty of room for swirling.
• Shake the sachet before gently sprinkling the powder into the glass.
• Vigorously swirl the water around in the glass making sure the powder is dissolved.

We highly recommend you take One Week Flat for 7 consecutive days. Many consumers like to take this course once a month. However, it can be taken on an ongoing basis or as desired.

Storage

One Week Flat does not require refrigeration. Store in a cool, dry place below 25°C (77 °F) and out of direct sunlight.

Customer reviews

• 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 :)

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

  Lorna - 6th April 2021

• I started taking the 28 course for my wedding and did not think I was very bloated but apparently so. I feel so much more comfortable when using these, my periods are less bloaty and after a big or heavy meal the bloating is also controlled and my trousers fit so much better. Does not taste of anything and I drink lots of water so this product is nice and easy for me. I found it cheaper on Medino website - hence the one less star.
