What is Protein? Simply put, protein is a group of complex organic macromolecules that contain carbon, hydrogen, oxygen, and nitrogen and are composed of one or more chains of amino acids. Proteins are fundamental components of all living cells and include many substances, such as enzymes, hormones, and antibodies, that are necessary for the proper functioning of an organism. They are essential in the diet of animals for the growth and repair of tissue and can be obtained from foods such as meat, fish, eggs, milk, and legumes. Our Seven Protein Sources 1. Fresh Chicken 2.

You see, dietary protein consists of two types of amino acids: 1. Essential—Which the body cannot produce enough of to satisfy its needs, and 2. Non-Essential—Which the body can produce quickly to sustain itself. Dietary protein supplies essential amino acids which results in a balance of essential and non-essential amino acids. These amino acids are critical to the body's ability to maintain and repair tissue, keep the immune system in peak performance, and ensure proper central nervous system function. Okay, so why seven? Well, providing essential amino acids is only the beginning, making sure your pet receives all the essential amino acids is where multiple protein sources come in.
