Casein Protein

Casein a high quality protein and is abundant in milk.  It has a slower rate of digestion than whey protein, and results in a slow but steady release of amino acids.  It has been shown to have anti-catabolic effects by supporting muscle growth and blocking protein breakdown. It also can promote fat loss by increasing your metabolism and reducing hunger.  This is why a good time to take casein is right before bed, where you are going a long period without the chance to refuel.  The most effective form of casein is micellar casein (this should be the first ingredient for the best results).
