Protein is protein and they don’t give you bigger muscles. You have to train hard to tear the muscle down to build bigger muscles. You will only get bigger muscles by working the muscle and not by eating more proteins. To help your body repair muscle, it is essential that you get the recommended daily allowance of protein. The Centers for Disease Control and Prevention recommend that adult women get 46 g and adult men get 56 g of protein each day. For the best nutritional value, you should concentrate on lean sources such as poultry and fish. Animal-based proteins are ideal because they contain all of the essential amino acids. A healthy diet will support proper muscle repair and development.
