WHEY PROTEIN ISOLATE: WPI digests and absorbs rapidly and is, gram for gram, the highest available yield of protein.WHEY PROTEIN CONCENTRATE: Closest to whole food and contains real subfractions. EGG ALBUMEN: Highly bioavailable and tolerated by most individuals, egg albumen is high in BCAA and arginine, contributing to hormone production and muscle building.PARTIALLY HYDROLYZED WHEY PROTEIN: Broken down into faster-absorbing peptides, this rapidly infuses muscle-building amino acids.ADDED BCAAS AND GLUTAMINE: The BCAAs l-leucine, l-isoleucine, and l-valine maintain, repair and build muscle tissue. L-leucine has been suggested to support protein synthesis and muscle growth. L-Glutamine has been surmised to support healthy immune systems. Some suggest L-Glutamine helps with recovery. Combined with Glutamine, it also fortifies muscle-building.MICELLAR CASEIN: It digests slowly, infusing valuable amino acids over several hours. Studies show this may protect muscle tissue. DIGESTIVE ENZYME BLEND: 60mg added to aid in protein digestion _and absorption.
