Protein Factory Whey Protein Isolate (WPI) is manufactured in Australia from local dairy produce. Utilising a cross flow micro filtration process, produces the highest level of undenatured protein available. Instead of using destructive chemicals, cross-flow microfiltration uses filters to separate protein from undesirable fat, cholesterol and lactose, based on molecular size and shape. This proess creates very low carbohydrate, lactose and fat levels, making it an ideal meal supplement or replacement.
