Milk’s protein helps build stronger muscles.

Each 8 oz glass of lowfat milk contains 8 g of natural, high-quality protein to help you get more out of your workout, build lean muscle, maintain a healthy weight and more.1-5


Not all proteins are created equal. Protein is made up of amino acids, and there are key amino acids your body can’t make on its own. High-quality protein provides all of these essential amino acids.

Milk protein is made up of specific and unique proteins—casein and whey—each of which are complete, high-quality proteins. Protein is needed for virtually every activity in your body and acts as the building blocks for everything from muscles to hair, bones to teeth. Your body needs protein to be strong and healthy.

In one study, healthy, untrained volunteers were randomly assigned to receive a drink containing either different types of milk protein—casein, whey protein or a placebo—one hour after performing a bout of resistance training. Consumption of both types of milk protein were found to bring about a similar positive net muscle protein balance, indicating that whole protein consumption can stimulate muscle protein synthesis after resistance exercise, which over time could lead to increased muscle size and strength.6

Lean muscle

Protein supplies your body with the amino acids it needs to build strong muscles. Along with being physically active, getting enough protein helps build and repair muscle.

Fuller longer

Protein helps keep you and your kids fuller, for longer—protein has a more powerful effect when it comes to satisfying your hunger than either carbohydrates or fats. Including enough protein at breakfast can help everyone feel full and satisfied with their meal.

Stronger muscles

A growing amount of research continues to suggest that not only does chocolate milk help athletes refuel and rebuild muscles after a tough workout, but it also helps build stronger muscles.

Energy and focus

Many experts now recommend adults start the day with 25 to 30 g of protein to help energize their morning. While the recommendation differs for kids, it’s important for them to get high-quality protein at every meal too. This helps keep kids fueled up and focused throughout the day.

Along with key bone-building nutrients like calcium and vitamin D, research shows protein is also a key factor in building healthy bones and maintaining bone health.

Maintaining a healthy weight

Protein plays a role in maintaining a healthy weight. As part of a calorie-controlled diet, protein has been linked to more lean muscle and less fat.
