Customer Reviews

good quality
This is my second favorite protein powder. It tastes fine mixed with other ingredients, but alone with water the flavor is.. bearable. It mixes readily, never clumpy. It's just the slightest bit grainy. My other favorite brand of soy protein isolate (rhymes with "guard dino") has a much finer powder, and that tastes better mixed solely with water, but it also flies everywhere whenever I open it up or measure it out. Probably not great for the lungs. Mixed into soylent or a smoothie, I can't taste the difference between the two brands. My only real gripe with BulkSuppements is the packaging, because I can never get that bag to seal properly! Not a problem if you transfer it to a different container though.*

soy protein isolate
My soy arrived promptly one day ahead of schedule and in good condition.
I supplement daily with 100gms to receive all the protein I need. It tastes great and was a great addition to my daily nutritional program.*

Loved it
I alternate between brown rice protein isolate and soy protein isolate and I like them both. It does the job of maintaining my muscles with the fewest calories and no animals are harmed in the process.*

Good powder, needs better packaging
Compared to pea, soy is less dusty and thus cleaner to work with. It won't make a dust cloud when handling. The taste is neutral which I like.

However, the bag does not close or seal for me. Please consider using ziplock or Hefty slider style openings.*

Excellent Quality Soy Protein
I have tried several pure soy protein powders. This one is very nice. It has a very fine texture and is reasonably priced compared to others. This is very close to pure protein. I make a shake out of it by adding water, vitamin D, flax oil, calcium citrate powder, and a small amount of taurine. It tastes best chilled. I put it in a shaker bottle because the ingredients will fall to the bottom. Then you just shake it and drink! I also put the soy powder in empty large capsules, and if I get hungry, I take a couple of capsules and then I don't eat between meals.*

If you love soy plant based protein this is for you
Do read the label for serving them out because it is not like the regular way protein it will taste extremely bad if you do 3 tablespoons of this product for one shaker cup very thick and I will say very dank I'm sure it works fantastic but not a product that I was looking for as usual no real taste just very hard to swallow great if you are not looking to build muscle I would say maybe if you're vegan or vegetarian who needs protein in their life sounds great But I think I'll stick to the clean whey *

On 5/4/2017 Johnathan said...

As expected
I ordered the wrong protein, i was going to get whey but got soy instead. It tastes like soy and is a bit thicker/grainier than i planned for. It disperses very well in room temp water. Do not use cold liquids to disperse. Banana easily masks any taste from the soy if you want to cover it up. I usually mix in water then add milk and any other fruits.*
