Gold Standard 100% Casein is a slow-digesting micellar casein powder from Optimum Nutrition, flavored Creamy Vanilla. Each 100 g delivers 75 g of protein, mostly casein with some whey, plus 9.4 g carbs and 3.1 g fiber, and it supplies BCAAs, L-leucine and L-glutamine along with calcium, zinc, magnesium and vitamins A and C. Casein forms a thick shake and digests over hours, which is why it is usually taken before bed or between meals rather than right after training. Against fast whey isolates it trades quick absorption for longer amino acid release; against plain unflavored caseins it wins on mixability and taste, though it is heavier and less instant than a whey shake.
