Optimum Nutrition Gold Standard 100% Casein – Slow-Release Micellar Casein Protein

You’ve put in the work. Now give your body the overnight support it deserves. Optimum Nutrition Gold Standard 100% Casein is a slow-digesting, micellar casein protein powder designed to steadily drip-feed amino acids while you sleep or when long gaps between meals can leave your muscles running on empty. Where fast proteins are perfect post-workout, this bedtime-friendly, sustained-release protein helps protect the gains you’ve worked so hard to build.

Why choose Gold Standard Casein?

Casein behaves differently to whey. In the stomach it gently gels, slowing digestion so you get a prolonged supply of amino acids. That’s why athletes reach for casein at night: it helps support muscle maintenance during the long, natural fast between dinner and breakfast. With Optimum Nutrition’s renowned quality standards and 100% micellar casein as the protein source, you’re choosing a shake that works as hard as you do.

What you’ll get in every serving

• 24 g protein to support the growth and maintenance of muscle mass.
• 3 g carbohydrates, 0.5 g fat and no sugar — easy to fit into cutting or recomp phases.
• Instantised for effortless mixing and a smooth, creamy texture.

When to use it

• Before bed: provide your muscles with a steady stream of amino acids overnight.
• Between meals: stay on top of your protein goals and help curb cravings.
• Any time you need slow-release protein: support recovery on rest days or during long days at work.

Taste and mixability

Gold Standard Casein is instantised to mix easily in water or milk. Shake, sip, and enjoy a creamy, satisfying texture without the lumps.

Who is it for?

Anyone who wants reliable, slow-release protein: strength athletes, endurance trainers, team sport players, or anyone aiming to maintain muscle while managing calories. If you already use whey after training, add casein at night for a complete, round-the-clock protein routine.
