A wealth of scientific research has proven that whey protein has the highest biological value (BV) of any protein (Renner, 1983). Biological value measures protein power and efficiency with which your body uses protein. With a biological value of 104, whey blitzes soy (BV-74), casein (BV-77), egg white (BV-88) and even tops milk (BV-91) (Renner, 1983). Not only is whey the easiest protein to absorb, it may also lower cholesterol and build strong bones. Designer Whey is a complete protein containing all essential amino acids. And thanks to unique Pressure-Driven Ultra-Filtration technology, the whey protein in Designer Whey products contains important nutrients missing from other whey proteins including glycomacropeptides, which can aid dieters in curbing and controlling their cravings, and lactoferrin, which boosts the immune system (Harper 2000).
