Offer now available for the Impact Whey Protein Milkshake. On sale with world wide delivery. Indulgence that earns its place.
The creamiest, most milkshake-inspired shake we’ve ever made, with every flavour crafted around the real thing. All built on the same protein standard that hasn’t changed in over 20 years, because some things don’t need fixing.
Every serving delivers 20g of protein* from whey protein concentrate and grass-fed milk protein isolate. The combination that gives you a high amount of protein per gram and the thicker, creamier texture that earns the milkshake name.
Plus, the macros are as serious as the taste is good, with under 112 calories per serve and zero added sugar*. Whether you’re fuelling muscle growth after a hard session, staying consistent through the week, or just want a shake worth looking forward to, it handles all three. Turns out indulgent and effective aren’t mutually exclusive.
Tested by experts. Trusted by millions.
What goes into your body matters. Impact Whey Milkshake is developed alongside our Performance Advisory Board and tested for purity twice — once at source and again internally before it leaves us. We’ve never cut corners on the standard, and we’re not starting now.
That commitment is why millions of people across the globe choose Impact Whey every day, from competitive athletes to everyday lifters and everyone working towards their goals.
A milkshake worth coming back to.
Creamy and deeply satisfying — each flavour built to deliver a proper milkshake experience with the protein to back it up. Mix one scoop with 200–250ml of cold water or milk and shake for 20–30 seconds. Use milk for a richer, creamier finish.
Works over ice, blended into a smoothie, or stirred through oats. One protein. Endless ways to Fuel Your Ambition.

I usually buy banana IWP but saw this new banana milkshake option and decided to give it a go, really enjoyed it and will buy again.

Vanilla ice cream – great taste, and come to think of it, it does taste like vanilla ice cream! I thought it was just vanilla when ordering so that was a nice surprise.
In my opinion, it makes a slightly more powdery tasting / mouth feel whey drip, compared to the standard impact whey but still great for adding some protein to breakfast/snack bowls.
Mixes really well, creating a very small amount of foam that quickly settles.
Where I don’t think it’s too great is the thickness – perhaps it’s my interpretation of the description but this is no where near as thick as I expected it to be. It works well with ice for a quick sweet fix, but I feel that by mixing the standard impact whey to a similar consistency is doable by reducing the liquid content somewhat – without the extra thickening agent.
In summary:
Slightly disappointed with the thickness but same great tasting whey. Not a repeat purchase for me personally.
Our delivery was upgraded to next day which was great and reflects the brilliant service myprotein offer.

Absolutely delicious banana milkshake protein! I was offered it at a discounted price and I’m so glad I decided to give it a try. The flavour is spot on, really smooth and tastes just like a proper banana milkshake without being too sweet. Mixes well and is easy to drink too. Definitely one of the nicest protein shakes I’ve had and I’ll 100% be ordering again!

I received a free sample of the vanilla ice cream flavoured Whey Protein Milkshake. I blended with some milk and ice cubes and honestly, it was so thick and creamy with no hint of protein powder. Really tastes like ice cream. Will 100% be trying the other flavours – lovely!
