Gold Standard 100% Casein by Optimum Nutrition is a dairy based protein powder supplement. Casein protein is a common protein found in milk that is a slower digesting protein than the likes of whey. When consumed, this protein forms globules and insoluble curds in the stomach that are more difficult for enzymes to digest. Because of their slow digestion, casein proteins are great for staying full and provide a slow release of protein to prevent muscle breakdown.
