When it comes to building quality muscle mass, there’s probably no single supplement better than a good protein source. Protein provides the basic backbone of any good supplement program. As a bodybuilder, you know that protein (amino acids) fuels muscular development. Not only does it provide the basic building blocks for mass, but protein can exert anabolic effects by promoting protein synthesis while simultaneously reducing protein wasting (catabolism). But like all things, quality matters, just as much as quantity. Better quality protein means a cleaner, purer, more absorbable protein. When it comes to whey protein, there’s a vast range in quality. Once considered a waste by-product of cheese, whey protein is one of the most popular and beneficial sources of supplemental protein today. There are two main types of whey processing utilized today: filtration and ion-exchange. Each has its own pros and cons. Filtration methods (e.g., cross-flow microfiltration, ultrafiltration, nanofiltration) involve physically separating protein components with the use of a pressure-driven membrane filtration system. Filtration methods preserve valuable whey protein microfractions such as glycomacropeptides (GMP), growth factors, immunoglobulins, lactoferrin, and others more effectively. Ion-exchange, on the other hand, typically produces cleaner whey products, with slightly less lactose and fat. However, because ion-exchange uses harsh chemical reagants such as phosphoric acid, hydrochloric acid and sodium hydroxide in the manufacturing process, many of the above microfractions are lost and denatured. The finished product contains significantly less biologically active fractions. Understanding these critical differences, only filtrated whey protein is used in Super Whey Pro. With Super Whey Pro, you get a premium source of undenatured, low-molecular weight whey protein. As a premium whey supplement, Super Whey Pro has the best microfraction ratio on the market. Typically, whey protein’s biggest fraction is beta-lactoglobulin. In some respects, beta-lactoglobulin is the least desirable fraction because it is highly allergenic. A high quality whey protein (typically filtrated whey) will yield a higher percentage of alpha-lactalbumin. Super Whey Pro has the best ratio around at 45% beta-lactoglobulin to 20% alpha lactalbumin. Plus, Super Whey Pro also contains approximately 10% immunoglobulins, 6% bovine serum albumin (BSA), 1% lactoferrin, and 1% lactoperoxidase.
