I have been using Optislim for 20 weeks replacing two meals. So far I have lost 13kgs with the help of light exercise.

The decision to commence on Optislim has to date been one of the best decisions I have made in recent times. I am committed and it is working. I also enjoy the variety, keeps me on track.

Optislim shakes have enabled my wife and I to lose a bit of weight and maintain that weight lose. We enjoy the shake flavours, especially the banana and strawberry that make it easy to return to program whenever our dietary intake has strayed offcourse.

Great Flavours and So Easy!! First time trying OptiSlim and wanting to lose weight in preparation for knee replacement surgery. Seems to be working - even with an enforced break from Optislim due to unplanned hospital admission. BAck home now and back on the shakes and have had steady weight loss. Favourite flavours - Espresso and Salted Caramel. Was good to try the variety pack as keen to try Strawberry and Vanilla, just wish that ChocMint was part of the variety pack as keen to try that too without buy a full pack.

Prompt delivery. Whether the shakes work time will tell. Taste good but a bit watery for my liking

Optislim platinum shakes are great value for money. The meal replacement plan provides a nutritious and filling meal. I have lost a little weight thiss week but it is too early to tell about long term results.

I like the flavours of the shakes and I am having two a day and have lost 6 kilos in 2 weeks. Would be nice if there were more flavours.

Firstly the cost is better than other weight loss Shakes I've tried! The flavours are yummy, blended with ice & water in the Blender, it like having a milk shake! More ice thicker drink yummy! Online have more variety of flavours than in store. My favourite is Espresso. I have lost weight & maintaining it with having atleast one shake a day combined with a balanced diet. I absolutely love and recommend this product!

Lovely tasting shakes leaving you full only down side I placed a large order and they did not send a shake container so I had it arrive and couldn’t make a shake till I could go out and purchase one I purchased 8 boxes and was new to the shakes so didn’t have one at home also the website didn’t show you how many of each item in stock so I had to keep changing selections until I could find 8 boxes that where available which was time consuming and slightly annoying as I made carts and then would not let me pay as said some items are not in stock but would tell me which ones so I had to keep de selecting and choosing other options until it worked and then no container but the product is good and would remained the product just needs to sort the other issues out

I have been using Optislim Platinum Plus shakes for 9 months and have lost 15 kilograms. Yesterday at my diabetes care plan appointment my doctor said I no longer need to take metformin. My hba1c has come down from 6.5 to 5.5. I am very happy I have reached my goal. I still have a shake for breakfast every morning as it keeps me full until lunchtime so I am not tempted to reach for something sweet mid morning.

Optislim has been part of my morning routine for years, and it continues to be a reliable, healthy start to my day. It keeps me feeling full through the first half of the day, gives me steady energy, and helps me maintain a healthy weight without any effort or overthinking. It’s simple, consistent, and genuinely works for my lifestyle. Highly recommend for anyone wanting an easy, balanced way to begin their morning
