Nature’s Ultimate Lean Muscle Protein

Muscle Milk® is a great-tasting, protein-enhanced functional formula that combines 32 grams of high-quality protein along with premium ingredients to provide sustained energy and recovery for performance and lifestyle.*

Muscle Milk consists of a precise blend of multi-source proteins, functional fats, low-sugar carbohydrates and 20 vitamins and minerals in a lactose-free formula. Muscle Milk is an ideal nutritional choice whether you are a performance athlete, watching your diet, or simply desire to gain strength & maintain lean muscle mass.*

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 standards for bother taste and performance. As a result, Muscle Milk has become America’s favorite protein drink.

Vitamin Mineral Blend

Muscle Milk is an excellent source of 20 health-promoting Vitamins and Minerals in each serving.

Lean Lipids Blend

Head scientists assessing the true role of fats in increasing lean muscle growth have found that all fats are not created equal. The type of fat determines whether you use it for muscle energy or store it as body fat! The LeanLipids™ used in Muscle Milk® encourages fat loss three ways:*

  • Medium Chain Triglycerides (MCTs), the predigested “fast burning fats,” are more likely burned for muscle energy and heat than kept as fat. 20% of Muscle Milk lipids are MCTs.*
  • Long-chain polyunsaturated fatty acids are also less likely to be stored as fat. Special enzyme engineering enables these lipids to be even more functional and enhance mineral retention.*
  • Polyunsaturated and monounsaturated fatty acids from canola and sunflower oil provide essential omega-3, 6, and 9 fatty acids.

So, while Muscle Milk may have slightly more fat than low-fat high-carb products, our Lean Lipids™ are designed to help you get leaner.

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 a form of glucose. Glucose is the only energy source for red blood cells and a preferred energy source for anaerobically exercising muscles.*

Precision Protein Blend

CytoSport Muscle Milk Amino Acids

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.*

Human milk is made up of unique and highly complex proteins, peptides and amino acids, which promote rapid muscle tissue growth. Muscle Milk’s Protein Blend includes these alpha and beta micellar caseins, alpha-lactalbumin, lactoferrin, L-glutamine and more. Nature made this precise mix to stimulate muscle growth to higher levels, and Muscle Milk provides the ultimate nitrogen delivery source.*

Muscle Milk helps muscle grow faster than gainers, whey or even creatine. This increased muscle growth is possible because Muscle Milk is the first product patterned after Nature’s ultimate anabolic food—human mother’s milk. Locked within the composition of human mother’s milk are long-held secrets to muscle growth potential. We made the next step and actually mimicked these important muscle growth factors into Muscle Milk. Muscle Milk helps you grow muscle like never before.*
