Optimum Nutrition ON Gold Standard 100% Casein Protein Powder takes longer to be broken down into its amino acid sub components, as slow digestion and absorption is required during bedtime when body typically goes for hours without food. 100% Casein is also free of artificial flavors, sweeteners, and synthetic colors and uses only protein from premium micellar casein to create a protein formula that is truly time-released.
