Casein Optimum Nutrition

Micellar casein is the highest grade casein available, and it feeds your body a steady stream of muscle-building amino acids over the course of many hours. Casein is especially helpful if you have a protein shake before bed, as it aids in important muscle recovery during your sleep and prevents muscle breakdown. And, of course, having a slow-absorbing, high quality protein source like casein in your personalized blend will be very effective at keeping hunger at bay.
