Optimum Nutrition Gold Standard 100% Casein

The slow protein. Casein sets into a gel in your stomach and releases amino acids over four to seven hours, which is why it's the classic before bed shake. You get 24 g of protein a serve, and it thickens up so well that plenty of people eat it as a pudding rather than drink it. Batch tested like the rest of the range.

• 24 g micellar casein protein per serve
• Releases over four to seven hours, so it suits long gaps between meals
• 600 mg calcium per serve
• 5 g naturally occurring BCAAs per serve

Chocolate Supreme: micellar casein, cocoa, natural and artificial flavours, lecithin, acesulfame potassium, sucralose.

Mix 1 to 2 scoops with 300 to 450 ml of cold water or milk. Best before bed or across a long gap between meals.

Contains milk. Gluten free.
