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

  • Awesome!

    Posted by on Mar 16, 2017

    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

    Posted by on Jan 21, 2017

    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

    Posted by on Dec 29, 2016

    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.

  • A very solid product

    Posted by on Oct 30, 2016

    Bulk Nutrients SPI combines the delicious taste and texture, mixability and nutritional profile of a premium product without the additional costs. Vanilla is the best flavour!

  • Quality soy protein

    Posted by on Oct 25, 2016

    This product is great quality and value for money. We use it because of allergy to whey protein. Wish there were more flavours other than just vanilla and chocolate.

  • A bit gritty

    Posted by on Oct 14, 2016

    I got the soy isolate chocolate due to the whey isolate not agreeing with me. The soy isolate tastes great but is a bit grittier than the whey. It's still a great tasting product and tastes better than the whey it's just a little grittier. All in all though a great product to make smoothies with.
