100% Natural Soy Protein Isolate
Bulk Nutrients' Soy Protein Isolate has one of the highest nutritional values available. It's 100% GMO free and contains no cholesterol, saturated fats or sugar.
We deliberately source a soy protein that is not thick and gluggy. So it mixes easily and is great consumed with just water.
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 plant-based proteins are flavoured with only completely natural ingredients. We use Monk Fruit and Stevia as a sweetener (of the highest grades available), which flavours the protein while adding no bitterness. What's more it's calorie free! Soy Protein is certified vegan by Vegan Australia.
For our natural flavours we use Natural Cocoa and Natural Chocolate flavouring for Chocolate and Natural Vanilla flavouring for Vanilla. Combined with Stevia and Thaumatin we have developed a great tasting natural product.
