Protein’ is defined a group of complex high-molecular-weight organic compounds, consisting basically of combinations of amino acids in peptide linkages, that hold carbon, hydrogen, oxygen, nitrogen, and usually, sulfur. Proteins are broken down in the stomach during digestion by enzymes known as proteases into tiny polypeptides to supply amino acids for the organism. Protein powders are made from four essential sources: whey (from milk), egg, soy and rice. Protein powder is commonly consumed without delayafter exercising, or in place of a meal. Protein powders can also be a conjugation of one or more ingredients.

These reduced sources of protein are processed into the powdered form, to be reconstituted into liquid form as a protein shake, or mixed with fruit juice or milk. Whey protein has a number of important benefits in areas involving sports nutrition, weight management, immune support, bone health, and common wellness. Egg white protein is a lactose- and dairy-free protein. Soy protein contains all basic amino acids, and is an cure protein for vegetarians. Soybeans also hold isoflavones, a type of phytoestrogen, which have a weak estrogenic activity. Protein shakes is designed to be taken regular as a dietary supplement.
