I started the slim replacement shakes on 17th March 2025 and have lost 3.5 stone on 17th August 2025. They are an amazing tool to help on a weight loss journey along side a calorie deficit. They taste amazing and so convenient to make up for a lunch time at work . They are a way of life for me now and love all the flavours. Come on girls you too can do it 💪

Started with protein uk about 7 weeks ago and have lost around 12 pounds. I feel so much better within myself and my confidence has returned. The flavours are so nice that it has made it easy for me to stick with. I am enjoying my weight loss journey with protein uk and would recommend it to anyone who is thinking of trying it.

Really enjoying my journey with the shakes. I have lost 1 stone 3 lbs in 6 weeks. Raspberry & white chocolate, mint chocolate chip, vanilla, banana & lemon curd are all great! Strawberry & chocolate next! The coffee shot in my morning vanilla shake is my favourite!
Helen M.5/5Verified
I love the taste and with all the added bits and bobs in it, means I don’t have to swallow lots of tablets. I was going to try a different flavour, but I’m frightened I won’t like them as much as the banana , I love it.
Julie D.5/5Verified

Sandra N.5/5Verified
I am new to protein shakes and my goodness, I am soo glad I tried them..delicious !! I have had raspberry & white chocolate, pineapple and coconut and strawberry and I have got to say they are all as good as each other..I have a shake in the morning and it satisfies my hunger for hours...love them !!! 😋😊
Jane R.5/5Verified
I am absolutely obsessed with Protein.com SLIM shakes! I have them in 8 flavours so far and can’t wait to try more when stock is replenished. I have one for breakfast, one for lunch and a healthy dinner in the evening. They are so easy to make, I use 275ml of water and pop four ice cubes in also, super creamy and delicious! I have tried other protein shakes and they always have a powdery texture which these shakes don’t have. The fat burning powders are lovely too :)
Susan C.5/5Verified
I’ve tried the Pineapple Coconut, Strawberry Cheesecake, and Cappuccino Ice Coffee flavours, and all three are surprisingly tasty. The shakes mix well, keep me feeling full for several hours, and are perfect for busy mornings or lunches. I’ve been using them as meal replacements and have found they help reduce snacking between meals. The Pineapple Coconut flavour is my favourite, while Strawberry Cheesecake is a great option if you prefer something sweeter. Overall, they’re a filling, convenient, and enjoyable choice for anyone looking to support their weight management goals.”

Allison F.5/5Verified
I love these shakes. In the 2 weeks I have been drinking them I've lost 5lbs which is amazing for me . I currently have pineapple and coconut and it tastes so good I cant wait to get up in the morning to have one
Anna F.5/5Verified
I’ve been struggling with my weight since having a hysterectomy at the age of 49.
I’m 54 now and came around your protein shakes on Facebook and thought l would give it a try.
I love it and it’s a bonus that it tastes so lovely. After 2 weeks I’d lost 7lb. At last I had found something that could help me get back into shape and gave me some energy back.
Fast forward 2 months, I’ve now lost 18lbs.
I’m so happy with my results and will continue my weight loss journey to get to my goal weight.
Thank you ♥️
Gillian C.5/5Verified
I have lost so much weight and feel amazing due to these shakes. I did find the chocolate one to thick. The rasberry and white chocolate is amazing and not powdery and i have this with water and strawberry i have with almond milk.
Natalie S.5/5Verified
The flavours are fantastic and go great with water. I lost 6lbs in my first week and feel great!
Julie W.5/5Verified
The flavours are amazing mango & strawberry are my favourite but have raspberry & white chocolate and lemon curd too.
I mix with water in the morning for breakfast & at lunchtime water and frozen mango or fruit which make the shake thicker . Losing weight slowly with exercise.
Belinda A.5/5Verified
I mix mine with water =13g protein
125g 0%fat Greek Yogurt = 13g protein
100g of frozen blueberries or Strawberries.
A whopping 30g protein for just under 300 calories.
Sharon J.5/5Verified
I've ordered the Mango Tropical before, however decided to have a change and go for the Raspberry & White Chocolate. It is so nice! Even with water, it's still creamy. The taste is gorgeous! I can't wait to try more flavours.
I've also noticed a change in how I eat. I typically have 2 shakes a day, and a full meal at tea time, however I'm noticing that I get fuller quicker, and don't seem to be snacking on biscuits, chocolate etc. It's certainly doing the job!
Laura M.5/5Verified
I have the Slim Lemon Curd flavour it’s delicious and blends lovely and thick with water. Have tried it once with milk, also very tasty. It would be AMAZING to have the option of a different flavour a day if they were sold as readily portioned sachets perhaps in a multi box purchase so you change it up, as a month of the same flavour could become demotivating when drinking them daily to reach your slimming goal.
Sarah B.5/5Verified
Love them blended with ice especially the coffee one it’s like and iced coffee they go down a treat on a hot day!
Kelly I.5/5Verified
Very surprised with the taste and texture from water n power and keep calling it a milkshake but clearly not ! I did add extra scoop in per serving to make thinker and helped me stay fuller for longer.
I've decided to plan my shakes when most likely to pick wrong foods so never been a breakfast person so 1st shake will be for dinner and then I have my teatime meal (anything I want ) and then make one for evening so dont binge infront of tv or order in.
It really is keeping my head out of the cupboard and fridge !!! Yet to weigh myself !!! 🫶🫶 so far so good !
And delicious.... strawberry next 😋
Christina F.5/5Verified
Been using shakes as replacement breakfast 💗
Maureen W.5/5Verified
This is my second tub of banana! Omg it’s amazing! Thick, creamy and so bananary (even if that is not a word 😊)
Absolutely amazing and only been on them for 2 weeks lost -6lb already! Hubby is on them too and -8lb 💛
Leanne K.5/5Verified

Nicola C.4/5Verified
I found this site, and thought why not try.
The delivery is very good next day if you order in time my choice was strawberry, great texture and tastes great. Bought another one.
However disappointed that the banana flavour I want to try has been out stock for weeks now. I would really like to try this one
When is this going to be available??
Amanda S.5/5

Love the banana one ive had Strawberry an raspberry and white chocolate an the banana is the absolute best its beautiful will definitely purchase again
Rhea B.5/5Verified
I love the pineapple and coconut 😍 it's so refreshing and I really look forward to having it 😍 it's yummy !
I then ordered Tropical Mango thinking it would have same refreshing can't wait to have it effect ! But no😞 I've tried a couple times with it so far but it's not happening 😞 so I've wasted a whole tubs worth 😞
Anyway I'm going to reorder pineapple and coconut again 😍love it 😍
It's a shame you don't do samples like alot of folk have also requested as it's made me sceptical bout trying a different one again incase I don't like it so sticking with my favourite for now !

Best Meal Replacement Shakes I’ve Tried
I’ve now placed two orders and can honestly say these are the best meal replacement shakes I’ve tried. On my first order I went for Pineapple/Coconut, Strawberry, Banana, and Mango Tropical. Every single one tasted great — no disappointments at all. The only small downside was that the Mango Tropical turned my urine bright yellow, but the flavour itself was lovely.
Just before I ran out, I placed my second order and added Blueberry Açaí and Lemon Curd to the mix. Unfortunately, Evri returned the parcel to the sender. When I contacted customer service, they explained that Pineapple was out of stock but would be back in a few days. That ended up being delayed, and by the time it returned, Banana had gone out of stock. Despite all that, they handled it really well: they sent everything that was in stock straight away and then shipped the Banana separately once it came back.
Flavour-wise, Blueberry Açaí has become my absolute favourite — it’s incredible. Lemon Curd was a bit too sweet for me personally, but still decent.
Customer service was great throughout, and the delivery issue was eventually sorted without any hassle. Best of all, the shakes are genuinely working: both my mum and I have lost over a stone.
I’ll definitely be purchasing again.
Tracy T.5/5
I love chocolate orange, chocolate fudge Lemon curd, banana, but my favourite is raspberry white chocolate, blueberry acai and pecan latte. Strawberry and mango are too sweet for me.
