Optimum Nutrition Gold Standard 100% Casein Creamy

When you’re not eating every few hours, your body still needs a steady supply of amino acids. That’s where Optimum Nutrition Gold Standard 100% Casein steps in. This slow-digesting, all-micellar casein protein is crafted to release amino acids gradually, making it the smart choice for night-time recovery and between-meal support. If whey is your go-to right after training, casein is the secret weapon that keeps you covered the rest of the day.

Why choose this casein?

Casein naturally forms a gel in the stomach, slowing digestion and delivering a sustained stream of amino acids. That means more consistent support for lean muscle maintenance while you sleep or power through a busy schedule. Each serving delivers 24 g of premium protein with only 3 g carbs, just 0.5 g fat and no sugar — a clean, convenient way to hit your protein goals without the extra calories.

Gold Standard quality you can taste

Made by Optimum Nutrition — the brand behind the industry’s first all‑micellar casein — this formula is instantised to mix easily in a shaker or blender. The “Creamy” profile offers a smooth, indulgent texture that’s perfect as a classic shake or a thicker, dessert-style treat.

How to use it

• Before bed: Mix a serving with water or milk 30–60 minutes before sleep for sustained, overnight support.
• Between meals: Use as a satisfying bridge to keep protein intake steady when you can’t sit down to eat.
• Get creative: Blend with ice for a thick shake, stir into oats, or whisk with less liquid to make a high-protein pudding.

Who it’s for

Ideal for lifters, athletes and anyone focused on protecting hard-earned muscle, curbing late-night snacking, and staying on track with nutrition goals. Whether you’re cutting, maintaining or simply chasing your daily protein target, this is the dependable, slow-release protein you’ll want in your stack.
