When Muscle Milk was first introduced, we attempted to emulate human mother's milk, one of nature's most anabolic, complete and balanced foods. In doing that, muscle Milk created a new category of protein products, while setting a new standard for both taste and performance. As a result, Muscle Milk has become America's favorite protein drink. Precision Protein Blend Muscle Milk contains a precise blend of proteins designed to create the optimal environment for exercise recovery and muscle growth. This precision protein blend contains rapid-releasing whey and slower digesting micellar caseins from milk protein isolate/concentrate plus calcium and sodium caseinates. This creates a constant supply of amino acids, the building blocks of muscle tissue. Choose The Right Kind Of Fat! The Lean Lipids used in Muscle Milk are more likely burned for muscle energy and heat than stored as fat. Medium-chain triglycerides (MCT), the pre-digested, fast-burning fats help provide the caloric energy needed to fuel exercise and recovery. Polyunsaturated and monounsaturated fatty acids from canola and sunflower oil provide essential omega-3, 6, and 9 fatty acids. Choose Carbohydrates Wisely: Low-sugar, high-fiber complex carbs are an important part of a healthy, active lifestyle. The starch-based complex carbs found in Muscle Milk supply energy to the body in the form of glucose. Glucose is the only energy source for red blood cells and a preferred energy source for anaerobically exercising muscles. Since we founded CytoSport in 1998, we've been dedicated to working with sports scientists, coaches and trainers to redefine protein enhanced products for active lifestyles and serious athletes - supporting performance when it matters. Over the years, we've expanded to create a comprehensive in that encompasses the athletic experience from preparation, to hydration, to recovery. Our products are among the very few that are subjected to third party independent testing to ensure they are manufactured in compliance with NSF International's GMP for Sport Registration. Our facilities are also inspected and regulated by the FDA. We carefully manufacture our powder products and ready-to-drink pre-blends onsite at our corporate campus in Benicia, California. Making responsible and efficacious products for athletes and active lifestyle individuals requires responsibility on all fronts. As our business has grown, so has our footprint. We have made environmental sustainability a focus and driver in everyday decision making. Through it all CytoSport has been committed to one thing, building athletes from the inside out.
