I have used Optislim in the past and lost 30kg with ease . Not only that but I continued to lose weight once I went back to normal eating thanks to advice leant on the program . 20 years later I need help to lose weight again so didn't hesitate to use Optislim again but this time I will try the Optislim platinum . Already down 4kg .

I began using the manshake for weigjt loss two years but then swapped to dukes for one year. I discovered optislim one month ago and so far have tried vanilla and caramel and am happy to say I comfortably prefer the flavors from the other options. Only wish that I found optislim sooner!

They work well, would like to see more soups in the box and the price of the meals are too high.

The new flavour MANGO is amazing and obviously all other flavours are great too especially BANANA.

Great tasting shakes that have given me excellent weight loss results (40kg so far). I have a lot of food sensitivities so the shakes have been a convenient and easy way for me to manage my diet.

I started two replacement meals a day the morning it arrived. I have been consitent on this for nearly two weeks. I am hoping to continue in the way l have been. I have lost weight although can't tell you how much. Its just that my clothes are showing it as is my face.

I find the Optislim range to be smooth, and not gritty like some others. The range of flavours is pretty standard. I’m not 100% sold on the mango flavour, but it’s certainly not unpleasant

I have been using Optislim for 3 years. Recommended by physiotherapist and dietitian to lose weight which it did successfully and made me feel better and lighter. I intend to continue with Optislim and Optislim soup to keep my weight in check I have also persuaded my husband to join me and it has settled his rumbling tummy.

The Platinum chocolate and strawberry shakes taste great and are much more filling than I expected making it easy to use.
