What is casein protein?

Casein is one of two protein sources derived from milk and is jam packed with nutrients. During cheese processing, whey is the liquid portion left over, while casein proteins become the solid (curds). These curd solids go on to create the dairy goodness we know and love (hello cheese!) but can also be washed and dried to create casein protein powder. Casein powders can be used in smoothies, healthy recipes, oatmeal and more!

What’s the difference between casein and whey?

With their complete amino acid profiles, both casein and whey protein provide muscle health supporting benefits. While whey protein breaks down and is absorbed rapidly, casein protein is digested at a slower rate. Considered a “sustained release” protein, the absorption of amino acids and protein synthesis from casein peaks after a few hours.

When choosing between whey and casein protein, consider your fitness goals. For pre and post-workouts, whey’s quick digestibility is optimal for providing a boost of amino acids. On non-training days or before bed, casein is a great choice for curbing late-night hunger and protecting muscle mass.

How to use casein protein?

Casein protein powders are a convenient (and delicious) way to boost protein intake. A favorite foundational supplement among athletes, casein protein provides nutrients for muscle growth, recovery, and repair.

Don’t let all the benefits to athletes fool you into thinking that casein protein is only for bodybuilders. Protein helps keep you feeling fuller longer, AND it supports the maintenance of lean muscle mass, making it an excellent addition to any healthy routine. You can mix it with milk or water in a shaker cup for a super-simple dose of protein or get creative by using it in smoothies, protein pancakes, oatmeal, or protein bites. The options are endless.

No matter your goal or flavor preference, there are so many options to choose from in the world of casein protein. Trust the experts at GNC to help you Live Well with our incredible selection of high-quality casein protein products.
