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

  • Its great

    Posted by on Aug 14, 2017

    I bought both the raw and vanilla flavour of the soy protein. Prefer the vanilla as the raw has a bit of an after taste. Both blend well.

  • Balanced soy protein isolate - so cheap

    Received my order of 5kg in under a week. Taste and "feel" is just as good as more expensive vegan protein powders. The whole order came in at under $100 with delivery... which is much cheaper than I can get anything equivalent at even large discount outlets locally.

  • Great Product

    This is a great product with awesome results. In periods where I am busy and can't train as much, this product allows me to retain mass quite well.

  • Good Product

    Being lactose intolerant, finding a good tasting protein that wont make me sick and that wont cost me lots of money is hard. This one ticks all the boxes for me and I couldn't be happier. The chocolate taste is easy to go down, you just have to make sure you mix it well. I've gone from saying yuck protein I wont touch that to actually drinking this after every work out! im excited to try some of the other products. Happy Days!

    First time I've tried this protein or any product from bulk nutrients and I absolutely love it! I got the vanilla and the chocolate. Both are great in a shaker on their own or mixed into a smoothie. Great taste without that fake sweetness aftertaste that some powders have. Will definitely return for more!

  • 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

    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.
