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
