Jarrow Formulas Whey Protein, Supports Muscle Development, 3 Flavor Variety Pack, 12 Count

The debate about “the best type” of whey protein is a frequent topic of discussion on bodybuilding message boards. Typically, one form is advocated based solely upon the manufacturing method used to produce it. For instance, whey protein isolate (WPI) is commonly touted as being a “purer” form of whey because it typically goes through more processing steps. However, these processing steps can destroy and eliminate some of the components that provide additional benefits. Whey protein concentrate (WPC) generally undergoes gentle processing, leaving many of the other natural components intact. In addition, the majority of clinical studies investigating the effects of whey protein supplementation have been conducted using WPC. Ultimately, the type of whey protein chosen (WPC vs. WPI) may not be as critical as the quality of its sources and the other components added to the final product (such as sugar or artificial ingredients versus natural flavoring, etc). When evaluating the quality of a whey protein product, one should read the Nutrition Facts panel to check for the source of ingredients (e. g. non-GMO, rBST-free) and the presence/absence of additives like artificial flavors and sweeteners.

Jarrow Formulas Whey Protein is made with whey protein concentrate that is certified to be free of recombinant bovine growth hormone (rBST). It comes only from U.S. cows and is made in small batches in an environmentally conscious facility that supports local dairy farms. It uses the high quality rennet enzyme system, which concentrates protein and preserves glutamine while producing a superior end product. Elevated temperatures are avoided during the manufacturing process. High temperatures and spray-drying can lead to the degradation of glutamine, which is an important amino acid for the synthesis of muscle tissue and for immune function. Finally, the product is ultrafiltered to remove greater amounts of lactose and fat from the final product, and it is free of any artificial flavors, colors, or sweeteners.
