Protein is an essential macronutrient that is needed to fuel your body for optimal functioning. Protein is comprised of smaller building blocks, called amino acids, which are needed for the growth, repair, and maintenance of body tissues such as skin, bones, and muscle. Protein helps with muscle recovery after a tough workout and helps you feel fuller longer. Protein powder is a convenient and delicious way to help you meet your daily protein needs. GNC offers a wide range of protein powders such as plant-based and vegan options as well as dairy-based protein powders, like whey and casein. Check out our best protein powder guide here.
