What do our customers say?

Not only have I lost 10lb in three weeks using this product but I’ve also noticed a drastic improvement in my energy levels and I’m also sleeping better. I honestly can’t believe the change that this product has had on me, I feel happier, more confident and I wake up feeling rested. And unlike other products I’ve tried in the past I noticed a difference within days.


I have been using this for the past 3 weeks and I love it. The taste is so much nicer than I expected from a powder - very tropical. I have stopped snacking and I’m an overall better state of mind regarding my eating habits. I truly think it is because of the routine these sachets have given me.


I found most ‘replacement’ products left me hungry but now use this instead of buying lunch and it keeps me going to dinner. Seeing a slow but steady weight loss.


Use to buy boombod but after a quick google this is much cheaper & has a lot of science behind it. No brainier boombod way more expensive not sure why anyone would buy it over this


... I can’t recommend it highly enough. When I read the claims I was very sceptical but over the last three weeks my energy levels have increased, my mood is great and the size of portions I eat now are half what I used to. I lost 10lbs in three weeks and I haven’t felt like I am on a diet... If you’re unsure whether to get this, don’t be. Use it with a healthy diet and just let the magic (science) do its thing

SlimBiome® has also been the subject of scientific studies, in which the following evidence has been concluded:

  • Independent studies from Oxford Brookes University shows that volunteers who took SlimBiome® changed their food choices, had reduced cravings for sweet food types and ate less fatty food. This is because chromium contributes to the maintenance of normal blood glucose levels
  • The ingredients in SlimBiome® are backed by over 1000 scientific publications containing data from clinical studies which demonstrate they help people lose weight. Specifically, glucomannan contributes to weight loss when used with an energy restricted diet
