Science: About Whey Protein Isolate
The scientific debate over which form of protein possesses the greatest anabolic power came to an end a few years ago, with one form emerging the clear winner. Compared to whey concentrates, caseins, milk or soy proteins, whey protein isolate (WPI) contains the highest amounts of the valuable microfractions in whey that support increases in lean muscle mass. It has higher concentrations of the essential branched chain amino acids L-isoleucine, L-leucine, and l-valine, and is a rich source of the powerful microfractions alpha-lactalbumin and glycomacropeptides, which are key factors in enhancing bioavailability, boosting immune response and greatly increasing anabolic activity. Whey isolate also has demonstrated a nutrient partitioning effect, driving nutrients away from fat storage and toward accumulation of lean muscle tissue. Finally, high quality whey protein isolate contains no fat, lactose or impurities.
Clearly, premium-grade whey protein isolate is your best muscle-building protein value. And no other bar on the market today contains more whey isolate than the amazing Supreme Protein®—a masterpiece of nutrition and flavor in every bite!
