100% 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.

    Great bloody product

    Posted by Anon on Jun 30, 2018

    Having never tried vegetable protein powders before, I was surprised to find how good this product is. Mixes very well & tastes great.

    Go-to protein

    Posted by Sarah on Jun 28, 2018

    Being lactose intolerant and occasionally too sensitive to low lactose whey formulas I find this soy protein blend the best for my stomach. Have tried earth protein as an alternative and had bad reactions possibly due to pea protein. This soy protein has been the best for a sensitive stomach, isn't overly sweet, and blends nicely with 300ml of water. I do add liquid sweetener drops as I prefer my protein shakes on the sweeter side, however much rather add my own according to taste rather than having to tone it down from the pack. Love both chocolate and vanilla. Raw is great for cooking without adding additional flavour.

    New favourite!

    Posted by Anon on Jun 13, 2018

    After getting over the taste and slight discomfort of my usual whey isolate i finally decide to switch to soy like i do anyway for every other milk substitute. This formula is perfect! very smooth and made well. I saw a few people complain about the stevia (which i usually hate) but its definitely the least sweetest protein I've tried and i love it. I usually hate fake overpowering flavours but the vanilla in this is so subtle and if you love the taste of soy products then you will love this.

    Protein for the Lactose Intolerant

    Posted by Anon on May 22, 2018

    It has been fantastic to find an alternative to help with protein requirements.

    Great Change from Whey

    Posted by Anon on Apr 25, 2018

    Nice to have a vegan alternative to whey. Not as mixable as whey or the Earth Protein mix but it's not a real issue. My only wish is if it could come in salted caramel flavour. It's definitely worth putting this into your mix of daily proteins.

    Good but too sweet

    Posted by Braden on Apr 03, 2018

    The soy protein seems to be giving me good results and is not making me bloated like some other WPI I have tried.
    I am finding a too sweet for my liking though, I actually add some unsweetened soy milk to try and tone down the sweetness.
