How We Produce Our Whey Protein Isolate We use milk from grass-fed cows, sourced for quality. During cheese production, the liquid whey is extracted and processed using cold cross-flow ultra-filtration. This method retains purity while removing lactose and fat — resulting in WPI90 with 90% protein content. Blended and packed in Australia, our 1kg bags let you mix and match flavours.
