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

  • WPI vs SPI

    Posted by on Jan 14, 2018

    The grainy texture is something I'm still getting used to, after switching from whey to soy. Though I prefer the flavours in this, because it's not sickly sweet (unlike the WPI). Great value for money too!

  • Perfectly Balanced

    Love this product. Bit more soy tasting than others i have tried but love that there is no sugar and the perfect amount of chocolate. Mixes perfectly. I'll be back for more. A Great Find!!

  • Solid choice

    Posted by on Dec 08, 2017

    I switched to soy when I realised how much cheaper it was compared to the Earth/WPI/WPC proteins. I can't really comment on the texture as I only ever use it in smoothies mixed up with oats/nut butters/fruit etc., where any issues with texture are mooted. WPI/WPC beat soy on protein vs carbs/fat, but soy beats Earth by that metric, as well as price.

    My only quibble with flavour is that the vanilla is far too sweet. Raw is as meh as you'd expect - mix it with whatever you need to make it taste better. Chocolate is fine as is.

  • vanilla vs. raw

    Posted by on Oct 27, 2017

    I first ordered the vanilla flavored soy protein isolate but it was so horribly sweet I hardly managed to swallow the first sip. It tasted like I just had a full sachet of stevia by itself and the aftertaste lasted for hours. Now I have a full kg of vanilla flavored protein isolate going to waste in my cupboard. I then decided to order a kg of unflavoured soy protein isolate and I'm quite happy with it. It doesn't taste great (I usually blend it with frozen fruit and make a smoothie) but it's definitively much better than the vanilla one.

  • The best!!!

    Posted by on Oct 22, 2017

    Holy guacamole I love this protein!!! I have tried so many vegan proteins over the years and this is the best. It mixes amazingly and the texture isn’t floury like vegan proteins can be. It tastes just like a glass of soy milk. Plus 5kg for only $89 is an absolute bargain.
    100% recommend

  • soy isolate

    Very dry find it best to mix with extra water or milk other than that taste is OK

  • Great vanilla soy protein flavour!

    Posted by on Oct 08, 2017

    I have tried many brands of soy protein powders in the past and half of them tasted like cough medicine. I'm actually liking this one, the vanilla favour is quite subtle and mixed well with other ingredients in a smoothie.

  • Great results, but smelly ass

    Building lean mass nicely, however the vanilla flavour tastes gross in comparison to the chocolate flavour. Also causing a bit of belly churning and flatulence. Would recommend

  • Soy protein that I don't need a spoon for

    Posted by on Sep 13, 2017

    I've once bought another brand of soy protein, each serve requires 500ml of water to mix, otherwise I would need a spoon. With BN's soy protein, I only need 250ml of water to get a good consistency, and its very easy to drink. Also my tummy has not had any issues digesting it.

  • Fantastic product

    Ordered the vanilla and the chocolate absolutely love them will be buying again
