When it comes to optimally building lean muscle, 100% whey protein is not the king like you've been led to believe.  Nature has it right. When researchers tested a combination of whey protein + casein protein, as found naturally in milk protein, they discovered that the two protein sources work together in a synergistic manner to build lean muscle.  Researchers have also found the combination of whey protein with casein protein results in a quick increase in protein synthesis along with a sustained elevation in plasma leucine levels.  It is important to consume both whey and casein protein together. That is why we have formulated select protein with Milk Protein Isolate, the first ingredient of our formula, which is comprised naturally of both casein and whey protein. This combination acts in the way that 100% whey protein cannot.  This is the science Select Protein™ is formulated from...a combination of the highest quality Milk Protein Isolate and Whey Protein Concentrate 80%.
