Love myprotein soy protein. Had all the flavours but particularly like the strawberry and cream. Tastes really creamy with soya milk rather than water. Good amount of protein per 30g shake. Very reasonably priced,,,(especially with discount). Cheers!!!
Goes Well With:
Soya milk


Ive been buying Myprotein soy protein for a while now with being lactose intolerant. I love them!. Most soya proteins take nasty but these have a lovely flavour especially the strawberry. Great amount of protein per serving and value for money. Always fast delivery too.

Acquired Taste

Have purchased lots of Soy Protein from MyProtein and always had strawberries and cream flavour. This time it was not available only Vanilla or Matcha so ordered two of each. What a relief I ordered the Vanilla! The Matcha is a acquired taste for sure, in fact in truth it is horrible. My wifw and I have very different palettes and we both think its horrible. Unless you like the flavour of weak tea and greens water steer well clear!!! Youve been warned.

The Bin!!

Tastes good

So I almost always use powder protein to mix with my porridge/oatmeal and previously I used pea protein from this brand. Taste is very nice and I use it in smoothies or shakes. Smells very nice as well, I have strawberry flavour. Price is very very decent as well.

does not taste like chocolate

The chocolate flavour doesn't taste like chocolate at all. It is also very grainy. I add fruits to it, i never have it on its own to mask the flavour. Im getting used to it, but would recommend the chocolate by its self


If you like Angel delight/pudding texture you'll love this! I brought the chocolate smooth one and although I was expecting a normal 'protein shake' consistency this is so much nicer and more pleasurable to eat! It makes a kind of protein pudding which tastes great (I mix it with coconut milk) and I have it with coconut yoghurt with berries or banana for breakfast or dessert. LOVE LOVE LOVE
Goes Well With:
Coconut milk, Coconut yoghurt, fruit

Great tasting

I brought soy protein isolate chocolate flavour and I found it has a lovely chocolate taste and very pleasant to drink. I mix mine with soy milk so it's a delicious drink after the gym and provides me with a good amount of protein which is especially needed as I do not eat meat and being pre diabetic I stick to a low carb, high protein diet. Great value. Will definitely order again.

Great soy-based protein

My body didn't seem to agree with Whey and other dairy-based proteins so I gave this a try. I originally ordered this in the 2.5kg unflavoured variant a few months back and have been slowly working my way through it. Taste: The unflavoured version tastes fine as long as you're okay with Soy milk / Tofu, if you get the unflavoured then mix in some bananas or FlavDrops. Consistency: It can be a little gloopy if you put too much powder in, my advice is to use more water or milk substitutes. Mixability: This stuff is harder to mix than standard Whey. It is thicker and less powdery. Should be fine to mix in a standard protein shaker as long as you fill it up with a little water first. I now use a blender to mix mine. Overall: After a few months of using this I'm very happy with it.
Goes Well With:
Soy milk (other non-dairy milk substitutes), non-dairy yogurt, bananas, berries, FlavDrops

Good lacto free alternative

I've been using this product over the last year or so and have found it fine to use and tastes good. Couldn't get on with whey powders as I have a lacto intolerance. Sure you've got to shake it a bit more to get it to blend and I add more water and lacto free milk 50/50 than suggested it's fine and still tastes good. Never had any stomach problems with this product. Recommended if you want a protein shake thats easy on your guts.
Goes Well With:
Bananas, blueberries

After 2nd shake great product

I ordered strawberry, really nice add more water then it says it's thick and is much better for my stomach than the milk protean
Goes Well With:
Water just add more then recommended
