    Soy protein isolate has an incredible amino acid profile, don't let anyone fool u into thinking it is inferior to whey. For the lactose intolerant, or those wanting a different protein powder, this is it. Unbelievable taste. Once mixed it becomes lightly aerated (yummy) and has a delicious nutty flavor. Mix with any of the organic flavours and u r in protein powder heaven! Hand to heart: Best protein powder I have ever had.

    my new go to protein powder

    The soy protein isolate taste good, is easy to digest and mixes well when blended, however in a shaker it takes a few minutes to shake the lumps out.

    Skepticism or plain ignorance

    I have read the product information and honestly thought that it was overrated. However, I decided to give it a try, just for a change. Now I'm a convert and taste great too. I think you need to out some flavours in this soy protein is great, similar to what is done for other products. I love chocolate. It really didn't upset my stomach at all. I recommend it to anyone, just give it a try.

    Finally convinced

    I have steered cleared of soy for so long..... Whilst trying to find a non dairy solution equal to whey. I use pea protein as well which is not suited to as many uses, and taste needs to be tinkered with . But This powder is so versatile and tastes good! I use it in chia pudding, quick post/pre-workout drinks, baking, sweets, meal replacement for busy days. Am currently leaning out and gaining muscle WITHOUT upsetting my tummy, compromising on taste or going hungry thanks to this product. highly recommend!
