Not great

Poor, very thick when mixed and basically impossible to drink. Like a thick syrup.

Good Protein

Used this as an alternative to dairy in my diet and was dubious at first but it mixes well and has no after taste like some other brands


I purchased this protein powder for when I go to the gym. I find it isnt very easy to mix in with porridge, it makes the porridge quite dry and thick. Its good to mix with water for a post-gym workout or just to increase your protein intake for the day. I wouldn’t recommend mixing with milk as it thickens quite quickly, water is best for a protein shake. Generally quite nice taste, better than plain flavour. Good product and would recommend to anyone who wants a soy alternative :)

Goes Well With:

Water and mixed into porridge

Better than I expected

So after reading the reviews I was dubious to whether I was going to like this... I ordered unflavoured to add to a breakfast shake of different ingredients - peanut butter, almond milk, cocoa powder and greek yoghurt. It mixed perfectly (blender) and was a lovely light milkshake consistency. Would definitely buy again but in chocolate flavour.

Goes Well With:

Anything to add flavour.

Good mixability and taste

Effective, does what it says. Mixes quite well although can get a bit frothy just using a shaker - I prefer to use a blender. But all in all it goes well in just about any type of food/drink

Goes Well With:

Water, milk, oats(porridge), smoothie

Good product

I’ve only tried the strawberry cream flavour and I mix with plant milk, ice and frozen strawberries and whizz it in the blender. It mixes well and has a good flavour and is like a smoothie. It is thicker than normal whey and a blender probably is a must with a little bit of extra fluid. I’ve been using it for a couple of years now and no complaints and if you are dairy free then I’d recommend as has a good protein content.

Goes Well With:

Frozen fruit

Great product, but not great consistency

This product does promise everything a protein shake should. It tastes good and it has a high protein content. The only downside, which is annoying when washing out shakers and even when consuming the drink is the consistency. It is very thick and requires a lot of water to mix it with, and sticks to the shaker somewhat. I will definitely buy again but the product could definitely be improved!

Disgusting Taste

I accidentally bought unflavoured and it was an absolutely disgusting taste and texture, really thick and almost undrinkable even after adding more water. I have not tried flavoured however i can't imagine it will be much better.

Great vegan protein

I have so far used my blender to mix this. I bought the non flavoured one as I was not keen on the sweetners used in the others. I have used it to mix with fruit and water and almond milk and banana smoothies. It is great, you can't really taste the Soy as you can in other protein shakes I have used before. I use this after my 10k runs and swims. So far so good. I am new to protein shakes so can't really say if it's made a difference with regards to increasing my weight.


This tastes revolting. It is grainy and makes me gag, even the tiniest spoonful is enough to ruin whatever you put it in. Tried to make a shake with banana, cocoa powder and the chocolate smooth version of this and hated it! Even my brother who likes everything had to wash his mouth out. So now I have a massive push of unwanted protein powder. Save your money!
