Whey proteins continue to dominate the bodybuilding industry and it seems the more we know the better whey proteins look. There’s been a tremendous amount of information, some valid and some purposely deceitful presented to you over the past five or more years with respect to whey proteins. We thought you could use some solid information to make a sound purchase the next time you’re ready to buy your protein powder.

Whey Protein Concentrate (WPC), when processed properly, is among the very best dietary proteins known to man. A WPC that hasn’t been properly produced may contain high levels of live bacteria and “dead” protein. The potentially treacherous path from whole cow’s milk to finished WPC can make or break the protein product sitting on your health food store shelf and it’s absolutely imperative that you choose the right one. How do you do that and what should you look for?
ISP Nutrition Inc.’s Honest Whey(TM) all starts in an American, whey-producing plant that takes in approximately 2 million pounds of milk per day. Needless to say, we’re not talking about someone’s basement operation, or even a small foreign company’s plant. They are routinely inspected by the Food and Drug Administration, United States Department of Agriculture and follow Current Good Manufacturing Processes. Checkout top protein powders here.
Through a unique ultrafiltration and diafiltration process, the watery whole whey is concentrated, leaving most of the lactose, fat and water behind and the native proteins intact. Honest Whey(TM) Natural will typically yield analytical results of 80% protein, 4-5% lactose as a part of total carbohydrates in the 6-7% range, 4% fat and 8-9% moisture and ash.
WPC is composed of protein fractions including between 45 and 61 percent Beta-lactoglobulin, 17 to 25 percent alpha-lactalbumin, 15 to 20 percent glycomacropeptides, 2 to 7% Serum albumin, 2 to 5 percent Immunoglobulin G (IgG) and other minor fractions such as Lactoferrin, Lactoperoxidase, Lysozymes and Growth Factors.
These words may be hard to pronounce but they are the heart of what makes a WPC tick. Will WPCs benefit the sick? Some recent research indicates a proposed immunological benefit of WPC in humans. Each specific protein within a WPC may hold significant value for promoting health, longevity, digestibility and absorption.
The current scientific belief is that the protein fractions above should be native (close to their natural form and concentration as found in whole cow’s milk). Research also tells us that various processing techniques, such as Ion-exchange, can remove 93 percent of the glycomacropeptide fraction of whey.
Whey proteins can be denatured when heated for prolonged periods at temperatures much above 150 degrees Fahrenheit. What does denatured mean? Simply stated, the proteins unfold into random structures, making them nonfunctional within the body. The issue of heat application and damaged WPC fractions is one of the most crucial aspects of WPC processing. Milk must be pasteurized and this requires the application of heat to prevent harmful bacteria from causing potentially deadly diseases from invading our bodies.
A review of published literature will reveal that High Temperature, Short Term (HTST) pasteurization techniques can be applied to milk and whole whey with an exceptionally low level of denaturation taking place, thus leaving the precious WPC proteins 97% undenatured and bioavailable. Honest Whey(TM) protein is produced using only HTST pasteurization techniques. For this, you can expect a safe and fully functional WPC.
Honest Whey(TM) is an agglomerated, and instantized WPC powder which means instant mixing and a remarkably high level of dissolvability in your favorite beverage.
We at ISP Nutrition, Inc. would be remiss in our advertisement, which you have so kindly spent time out of your busy day to read thus far, was lacking information to further clear the errors in whey protein terminology commonly found on other whey protein products.
Additionally, ISP Nutrition, Inc. suggests that if you see the terms “Ionic Whey” or anything other than the proper “Ion-exchanged Whey Protein Isolate” (IWPI), and the company claims to have IWPI protein in their product you should write or call the company and ask for the source of their protein. Currently, there is only one American company producing IWPI.
Buyers should expect to pay approximately $24.00 per pound for a dietary supplement containing only IWPI. There is no current research which indicates that IWPI packs on more muscle in healthy weight-lifters than a Whey Protein Concentrate (WPC).
* Whey peptides have been shown by some researchers to be better absorbed than amino acids while others have failed to confirm these findings in normal individuals. Furthermore, any absorptive benefit may disappear if the peptides are consumed with carbohydrates. Caution should be used when trying to match data from a study where peptides were the only source of dietary protein with a dietary supplement formulated with multiple protein sources and whey peptides.
Many factors effect the peptide effects. No published research indicates that whey peptides are more effective for promoting contractile muscle tissue (skeletal muscle) in healthy weight-lifters over a WPC.
* The biological value (BV) of whey proteins is among the highest known, however, leading United States researchers do not recognize any biological value greater than 100. The BV is defined as the portion of absorbed protein that is retained by the body for maintenance or growth.
