Faster digesting protein is desirable immediately before and after exercise to help refuel recovering muscles, but slow digestion and absorption may be more beneficial at other times including bedtime when your body typically goes for hours without food. Casein products are acid sensitive and thicken in the stomach. Compared to some other proteins, it can take longer for our Gold Standard 100% Casein™ to be broken down into its amino acid subcomponents. By using only premium micellar casein as a protein source, we've created a formula that sets the standard for slow digesting protein support. 24g of Micellar Casein

  • 24g of Anti-Catabolic Micellar Casein
  • Nearly 5 Grams of Naturally Occurring BCAAs per Scoop
  • Nearly 5 Grams of Naturally Occurring Glutamine and Glutamic Acid per Scoop


Add on heaping scoop of Gold Standard 100% Casein™ to a shaker cup filled with 10-12 oz of your preferred beverage. Cover and shake for 25-30 seconds. Take Gold Standard 100% Casein™ immediately before bed and in between meals when delayed protein delivery is desired. You may drink Gold Standard 100% Whey™ or Pro Complex® proteins before and immediately after workouts for a rapid shot of amino acids.
