What are essential and non-essential amino acids?
The body is able to make non-essential amino acids from other amino acids in the body. The body, however, is not able to make essential amino acids; the only way to get them is through diet. One of the best ways to ensure you are meeting your needs is by eating high-quality protein foods. Protein sources that contain all of the essential amino acids are called complete proteins. Whey protein is a naturally complete protein.
