Optimum Nutrition Gold Standard 100% Casein — Chocolate Supreme
A slow-digesting micellar casein protein with 24 g of protein per serving for longer gaps between meals or overnight use.
Why choose it: Casein releases amino acids more gradually than whey and can be useful before a long period without food.
Avoid if: You have a milk allergy or significant dairy intolerance.
Trade-off: It is thicker and slower-digesting than whey, and slower digestion is not automatically better for muscle gain.
