Optimum Nutrition Gold Standard 100% Casein Supreme — your night-time nutrition, dialled in

When your day ends, recovery begins. Optimum Nutrition Gold Standard 100% Casein Supreme is engineered for those crucial hours when you’re not eating—providing a slow, steady release of amino acids to help protect hard-earned muscle while you rest. Each serving delivers 24g of premium micellar casein, with added zinc and magnesium, plus naturally occurring glutamine, to support your training goals around the clock.

Why athletes choose Casein Supreme

Unlike fast proteins, casein forms a gel in the stomach, releasing amino acids gradually. That makes it the smart choice before bed, between meals, or anytime you want sustained protein. With just 0.5g fat and no added sugars, it fits seamlessly into lean, performance-focused nutrition. You’ll also get 680mg of calcium per serving to support normal muscle function—so you can train hard and recover smarter.

Thick, creamy, and versatile

Mix it into a smooth shake, or go thicker for a dessert-like casein pudding—either way it tastes great and keeps you feeling satisfied. The 1.82 kg (55 servings) format offers outstanding value for consistent, daily results. Packaging may vary.

Perfect for: lifters, endurance athletes, team-sport players, and anyone wanting dependable overnight or between-meal protein support without unnecessary sugars or fats.

More Info

Indications

Casein proteins are sensitive to pH levels and form a gel when they come into contact with the acidic environment of the stomach. Due to this, they can take up to twice as long as other protein sources to break down into amino acid subcomponents. These qualities make casein proteins ideal for preserving muscle and acting as an "anti-catabolic" protein. It is recommended to consume casein protein between meals or before going to bed, as it is often referred to as "night time protein."

Directions

Add one heaped scoop of Gold Standard 100% Casein with 300 to 350 ml (10 to 12oz) of water or preferred beverage. Use ON 100% Casein Protein first thing in the morning, immediately before bed, in place of small meals and/or any other time when delayed protein absorption is desired. To encourage a positive nitrogen balance, consume approximately one gram of protein per pound of body weight per day from a combination of high protein foods and supplements. For even better results, consume your daily protein allotment over several small meals spread evenly throughout the day.

Safety Warning

Always reseal after use, keep in cool dry place.

Food supplements should not be used as a substitute for a varied diet. Do not exceed the stated recommended daily dose. Keep out of reach of young children. Storage: always reseal after use, keep in a cool dry place.
