nteresting article from Will Brinks on front page of bb.com .
He says that whey concentrate has more growth factors including
lactoferrin. Which is probably true since lots of the good stuff is in the fat which is removed by CFM and concentrate has more fat+lactose.
Protein factory's description of its concentrate is "Using the ion-exchange process the whey is concentrated to remove ....". Why is the filtering process ion-exchange? Kindof leery about 'ion-exchange'. Any advise here??
