Good for those with Whey/Vegan Protein Intolerance

By: on 27 October 2023
I’ve tried so many brands and they all give me bloating, diarrhoea (from Whey, Collagen) or constipation (Pea/Vegan Proteins). This was the first brand that mixes well and does not give me any digestive issues. Very happy with the product. Taste nice

Soy Protein Isolate - Great Product

Super fast delivery. Great Product. Will purchase again.

Pleasantly Surprised

Having used Professional Whey's WPI powder for years I was at a loss when I developed a cow's milk allergy. Not wanting to eat a kilo of chicken every day I thought I'd give the Soy Protein Isolate a try given its close approximation to the WPI. What a surprise the SPI powder mixes as well as the WPI and the taste is enjoyable on its own with Soy Milk or with some flavouring. (Cinnamon is a winner!) Would absolutely recommend giving this SPI a try!

Good Quality Soy Protein Isolate

Compared to a different brand of SPI that I tried, this one is much better. It is smoother, less caked-up inside, and the packaging is good. I had to throw out the other soy product despite barely using it because it gave me severe headaches and diarrhea, but this one had no side effects, so I'm very happy. Will definitely re-purchase. I guess that's what you get when you order a good brand that is made in the USA.

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

By: on 9 March 2014
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

By: on 2 October 2013
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!
