– A reference casein for extended release
Optimum Nutrition's 100% Casein Gold Standard is formulated to support muscle recovery during sleep or between meals. Thanks to its micellar structure, this protein is digested slowly, ensuring a steady supply of amino acids for several hours.
-Ideal for nighttime or as a snack
The slow release of amino acids makes it a perfect choice to prevent muscle catabolism during overnight fasting. It's also an excellent, healthy appetite suppressant between meals.
– Optimum Nutrition quality guarantees optimal purity and effectiveness, without compromise.
Why it promotes lean mass:
1. Pure and slow-release protein:
With 24g of micellar casein per dose, it provides a constant supply of amino acids for several hours, limiting muscle catabolism, especially at night.
2. Low in calories, carbohydrates, and fat:
• Only 115 kcal per serving
• 1.9 g of carbohydrates
• 0.8 g of fat
This makes it an ideal protein for controlled, lean muscle gain without storing excess fat.
3. Good satiety + natural appetite suppressant:
The slow digestion of casein limits cravings, which helps control total calorie intake — a key factor for lean mass.
4. Optimized muscle recovery:
The presence of zinc (2.5 mg) and magnesium (93.5 mg) supports protein synthesis and recovery, essential conditions for the development of quality muscle.

But under certain conditions:
• It must be combined with regular and progressive strength training.
• Your overall diet must be high in protein and calorie-controlled.
• It's not a weight gainer: it's not meant for rapid weight gain, but for slowly building dense, lean muscle.
⸻
Ideally, it should be used:
• As a pre-bedtime snack
• During a cutting phase to maintain muscle mass
• Alternating with post-workout whey protein to provide protein throughout the day
