Slow-Release Recovery Fuel for Serious Athletes

Recovery doesn’t stop when your workout ends—and neither should your nutrition. Klean Casein delivers 24g of premium micellar casein protein per serving, fueling your body with a slow, steady stream of amino acids while you rest, recover, and rebuild.
Why Klean Casein?
