Optimum Nutrition 100% Gold Standard Casein: The Ultimate Slow-Digesting Protein

Fast-digesting amino acids are perfect for right before and after workouts to help with muscle recovery, but for other times, like before bed, a slower digesting protein is ideal. Optimum Nutrition's 100% Gold Standard Casein is designed for just that. This slow-digesting protein is perfect for providing a steady release of amino acids, especially during periods like sleep when your body goes without food for hours.

Why Gold Standard 100% Casein?

Casein proteins are acid-sensitive and form a gel in the stomach, meaning they break down more slowly than other proteins. This gives your muscles a steady supply of amino acids for extended recovery. Optimum Nutrition uses only premium micellar casein to deliver the best in slow-digesting protein support.

What is Micellar Casein? Micellar Casein is a slow-digesting form of protein derived from milk via ultrafiltration. It thickens in the stomach, releasing amino acids gradually over several hours, making it ideal for extended muscle recovery.
