Pure Whey Protein

There are two definitions of pure whey protein. One is whey protein which is of the highest purity whey protein, i.e. there’s nothing else in it. Another is whey protein which hasn’t been processed heavily and retains more of its natural characteristics.

High Purity Whey Protein

If the pure whey protein you’re looking for pertains to the first definition in the opening paragraph, that of highly filtered whey protein yielding high purity (high protein derived calories per total calorie serving) then your best bet today is to look into the range of Ready-To-Drink (RTD) whey protein supplements, many of which are now as close to 100% pure whey protein as can be.

Minimally Processed Whey Protein

All whey protein products have been processed – we want the whey protein, after all. Different levels of filtration give different levels of purity.

Without doubt, the least processed whey protein is whey protein concentrate and I recommend you look for whey protein supplements that are comprised of this. It preserves the basic integrity of whey, without eliminating beneficial compounds like isolation and hydrolyzing filtrations in the pursuit of higher purity.
