Why Choose Optimum Nutrition Gold Standard 100% Casein?

You put in the work at the gym, but real muscle growth happens while you sleep. While fast-digesting Whey is perfect post-workout, it leaves your system quickly, leaving your muscles starving by 2 AM. Optimum Nutrition Gold Standard 100% Casein is the ultimate “nighttime hero” designed to form a gel in your stomach, slowly releasing amino acids for up to 8 hours. It stops muscle breakdown (catabolism) dead in its tracks, ensuring you wake up fully recovered and ready to crush your next session.

Key Benefits

💪 24g of premium micellar casein specifically engineered to prevent muscle loss during sleep or long periods without food.
⚡ Packed with nearly 5g of naturally occurring BCAAs and Glutamine to accelerate overnight recovery and reduce soreness.
🔋 Satiating formula that keeps you feeling full for hours, effectively curbing late-night hunger pangs and cravings.
🥛 Famous for its thick, creamy texture—add less liquid to whip it into a delicious, guilt-free pudding treat.
🏆 The World’s #1 Best-Selling Casein protein, offering the Gold Standard in quality and banned-substance testing.

Expert Verdict: Who is this for?

This supplement is a non-negotiable tool for anyone serious about preserving lean muscle mass. It is especially critical during a cutting phase, where caloric deficits put your muscles at risk of breakdown, and the high satiety factor helps you stick to your diet. However, it is equally valuable for bulking athletes who need to maximize protein synthesis 24/7. In short: if you want to ensure your body is building muscle “on the night shift,” this is for you.
