True Protein’s Whey Protein Isolate Cold-Filtration is derived from whey protein concentrate, but ultimately from sweet dairy whey.  Isolates, Cold-Filtration, Microfiltration and Ion-Exchange, are protein powders that are the next steps to further process whey protein concentrate.  The Cold-Filtration process is a procedure of separating the proteins through the use of micro filtering the mass all while using a cold or “chilled” process (environment).  These filters allow the protein to be removed from the unwanted fat, lactose and the like.  Cold-Filtration Isolate is virtually fat free and lactose (sugar) free. 
 
So what is the difference between Cold-Filtration and Microfiltration?  They both use the same extraction process of filtering, but the Cold-Filtration is just that, the liquid mass is chilled and then filtered.  As well the mass is then sprayed dried in a non heat environment to preserve the undenatured proteins.
 
Using the Cold-Filtration method, the overall protein is said to only be 0-3% denatured, in comparison to other proteins that can be denatured up to 15%.  Whey Protein Isolate Cold-Filtration is very high in bioactive whey protein fractions, including immunoglobulin, lactoferrin and glycomacropeptides.
 
Whey Protein Isolate Cold-Filtration is a great whey protein for users who experience bloating and other problems associated with whey protein concentrate.  As well, users who want a higher protein percentage per product, an Isolate is a great choice. 
 
Whey Protein Isolate Cold-Filtration possesses an extremely clean taste.  This product alone is opaque in nature (almost clear) and does not have any distinct flavor.  Great for the individual that dislikes the taste of “protein powders.
