Used to be good, what happened Review by
  • star

I loved this and other Red 8 products years ago, was super happy to find this but it's just not what it was. It used to taste amazing and was very smooth - now it tastes sour and harsh like chemicals and is anything but smooth. I'd guess the Soy is not the same grade as it was (dare I say Chinese?). I've ended up using Tony Sfeirs Soy which to my surprise is very much better. Even the Red 8 packaging used to be cool but now it's this cheap nasty plastic - very disappointed to be honest, definitely wouldn't buy again I threw it out.

This is the first time that I've tried a protein powder, and this vanilla soy isolate is great. Obviously I have nothing to compare it to but it tasted delicious and extremely creamy, even though there was no dairy in it.

Yummy whey protein alternative Review by

I'm using this while on a low calorie diet and it's great - really yummy with the Vanilla flavour and has a smooth consistency. I just add water and shake it up and it mixes well. Will definitely buy again.

Excellent product! Review by

I started using this when I had lost a whole lot of weight and found myself really weak, and simple things like walking up a hill became difficult. It tastes great mixed with nothing but water, and is a lovely texture - it actually dissolves/blends completely making a nice think smoothie unlike most protein powders which are grainy and don't actually blend into water, and it has stevia as a sweetener and no nasty ingredients! Within a short while regained more strength than I had even had before I got sick, even though I didn't put a lot of weight back on, but I did get an awful lot of nicely defined muscle tone :) It's a winner in my book, I haven't stopped using it since :) Yummy tip, this powder (vanilla flavor) with water, LSA, and maple syrup as a breakfast smoothie! Oh My!
