Casein, a slower digesting and absorbing protein can be used after exercise, between meals or before bed to help support satiety and muscle recovery. GOLD STANDARD 100% CASEIN™ delivers BCAAs to recovering muscles for several hours. By using only premium micellar casein as a protein source, we’ve created a protein powder that sets the GOLD STANDARD® for slow digesting protein support.

I love this protein! I've tried other casein but this one mixes the best without tasting chalky. The flavor is delicious and I love mixing it in to greek yogurt and chocolate milk! *

Best tasting casein protein. Great bed time slow digesting protein source . Gained 5 lbs since I switched from a whey protein to casein. Bed time is one of the most critical times to absorb protein because it's the longest amount of time you go without food*
