Product Description

Bulk Nutrients' All Natural Soy Protein Isolate

Bulk Nutrients' Soy Protein Isolate has one of the highest nutritional values available. It's 100% GM free and contains no cholesterol, saturated fats or sugar.

Soy Protein Isolate has a great amino acid spread and can be used for building muscle as well as losing weight, or simply substituted for a meal.

Easy on the stomach

Vegetable proteins are gentler on the stomach than animal proteins so are suited to people with animal product allergies or sensitivities.

At Bulk Nutrients, we don't add anything to our Soy Protein Isolate that shouldn't be there.  That means it's free from any additives, artificial flavourings or sweeteners and is 100% pure.

Suitable for vegetarians and vegans

Our vegetable proteins are flavoured with only completely natural ingredients. We use RA 98 Stevia as a sweetener (one of the highest grades available), which flavours the protein while adding no bitterness. What's more it's calorie free!

For our natural flavours we only use Natural Cocoa for Chocolate and Natural Vanillin for Vanilla. Natural Vanillin and RA 98 Stevia come at a very high cost, however we feel these ingredients are important to ensure a great tasting natural product.

We take extreme care when producing our vegan proteins, we have dedicated lines and machinery for our non dairy products to reduce the chance of cross contamination. Please be aware that we produce dairy proteins in the same facility, and despite our efforts there is a chance cross contamination (at very small levels) can occur

  • Soooo good

    Posted by on Jun 13, 2017

    I've ordered twice from this website. The first time my order was delivered the next day and I thought it was just a fluke. Ordered this product and it was delivered the next day! So good! The product itself tastes amazing. Not too sweet but just sweet enough. Great alternative to whey protein. I have a protein smoothie every day and I enjoy it so much more now with this protein. I'm just about to buy some more

  • Awesome Vegan Protein

    Posted by on May 07, 2017

    Highly recommend
    I ordered 5kg of this protein in both chocolate and vanilla, I have never been a fan of chocolate flavoured anything but I actually prefer the chocolate as its not overly sweet and has a nice cocoa flavour to it. the Vanilla isn't really very strong as a flavour which is a shame but still very pleasent.

    I would love if they did the salted caramel flavour in this like the Vegan blend but thats only a minor issue.

  • Pretty average

    Posted by on Apr 12, 2017

    Not a very pleasant protein to drink straight but is okay once you add peanut butter and/or honey to it to mask the strange after taste it seems to have. Texture isn't too pleasant either. Bulk's dairy based proteins are definitely a better choice. This protein is gentle on the stomach however which is a plus.

  • Awesome!

    The Soy protein isolate is a great option for those who want to take protein supplements naturally. I rate this product 4/5 because i found it tastes a little grainy. Other than that its a great product!

  • Okay, wouldnt buy again.

    Posted by on Mar 05, 2017

    Tried as an alternative to WPI. Agree it does what it says, but due to grainy, texture and lack of vanilla flavour I probably wouldn't buy this again.

  • Decent soy protein

    Posted by on Mar 01, 2017

    I tried a soy protein as my stomach reacts to WPI. I mix my protein just with water and am used to the smooth texture of a WPI, so the very slightly furry, thick texture was a little hard to get used to at first, but nothing compared to the gross sandy texture of a pea/rice protein. Shakes and dilutes perfectly and doesn't get stuck in the bottom. I was meant to order vanilla as I find chocolate proteins/flavour too sweet, but ordered chocolate by mistake and it is actually quite a nice, subtle flavour and not sickly sweet at all. Would definitely buy again.

  • Happy

    I am really pleased that this vegan choice is available. It helps me with the days when I don't control the menu and need to insure adequate protein. It's tendency to cling to containers once wet means I can't give it the 5 stars, but still a very good product.

  • Product good, lifespan bad

    Posted by on Jan 13, 2017

    The product is good like it says and perfect for my lactose intolerance. However was shocked to see that it expires in 6 months and I bought 2 kilograms of it. Sneaky.

  • Easy to drink, good for digestion

    Have mine with almond/coconut milk, It mixes well, the consistency is nice in the nutri bullet. Choc and vanilla flavours are great , but If you want the raw flavour make sure to mix it with something else e.g. blueberries, dates, honey, etc.
    Also very affordable!

  • 1kg Raw unflavored

    Posted by on Dec 11, 2016

    I bought the 1kg Raw unflavored. The taste is pleasant, very close to unsweetened soy milk. The powder is fine, mix just fine although does have a very minor sandy texture even with plenty of water, nit picking here. It's vegan so my body can cope with it better, also won't leave a strong smell in the container or the shaker, unlike the ON Gold Standard ones do. This soy protein has been good to me. Only complaints are on the packaging, the scoop handle is too short, and the zip-lock bag opening is hard to get into.
