Natural Whey Protein Isolate WPI

All natural ingredients, GMO free

Bulk Nutrients natural Whey Protein Isolate (WPI) is one of the cleanest and purest whey proteins available in the world. It comes from grass fed cows and is 100% hormone free. Our Natural WPI contains virtually no lactose, and being extremely low in both fat and carbs, it is an ideal post training/exercise protein shake.

Our Whey Protein Isolate is manufactured using cross flow micro filtration, and is naturally rich in branched chain and essential amino acids (BCAAs and EAAs) and is therefore perfect for muscle recovery and repair. High in protein at 91% it has less than 1gram (g) of fat or carbs per serve.



All natural flavours and sweetened with natural Stevia

Our Natural WPI is great tasting and we use only natural flavours and sweeten with stevia to ensure an all natural product.

We use natural cocoa and vanillan at the lowest inclusion rate to ensure our natural Whey Protein Isolate is pure and also great tasting.
