Optimum Nutrition Gold Standard 100% Casein – Chocolate Supreme
Unlock Overnight Muscle Recovery with the Gold Standard.
Maximize your recovery window while you sleep with Optimum Nutrition Gold Standard 100% Casein. While fast-digesting whey protein is ideal immediately post-workout, your body needs a sustained protein source to protect and build muscle during long periods without food—specifically overnight.
This slow-digesting formula forms a gel in the stomach, releasing amino acids gradually over several hours. Packed with 24g of premium protein and essential amino acids, it is the ultimate "nighttime protein" to prevent muscle breakdown and fuel recovery while you rest. Indulge in the rich Chocolate Supreme flavor and wake up ready to train harder.
Key Features & Benefits
- 🧱 Slow-Digesting Formula: The primary protein source is micellar casein, which digests slowly to provide a steady stream of amino acids, making it ideal for nighttime recovery or long gaps between meals.
- 💪 24g Premium Protein: Each serving delivers a robust 24g of high-quality protein to support lean muscle maintenance and growth.
- 🧬 9 Essential Amino Acids (EAAs): Fortified with the building blocks of muscle to enhance endurance, repair tissue, and support overall recovery.
- 🍫 Chocolate Supreme Flavor: Satisfy your sweet tooth with a rich, creamy chocolate taste that feels like a cheat meal but works like a supplement.
- 🛡️ Anti-Catabolic Support: By keeping your muscles fed for hours, this formula helps prevent muscle breakdown (catabolism) during sleep.
- 🥣 Versatile Mixability: Thicker than whey, this powder is perfect for shakes, smoothies, or making a protein "pudding" for a filling snack.
Suggested Usage
Casein protein behaves differently than whey. Because it thickens when mixed with liquid, it offers unique ways to consume it.
1. The Bedtime Shake:
Add 1 scoop to 10-12 fl oz of cold water, milk, or your favorite beverage. Shake for 30 seconds until dissolved. Drink 30-60 minutes before bed.
2. The "Protein Pudding" (Customer Favorite!):
Mix 1 scoop with a very small amount of milk or water (approx. 3-5 oz) in a bowl. Stir until it forms a thick, pudding-like consistency. Place in the freezer for 10 minutes for a frozen treat!
3. Between Meals:
If you know you won't be able to eat for several hours, drink a serving to keep you feeling full and to keep your muscles fed.
Common Frequently Asked Questions (FAQs)
Q: What is the difference between Gold Standard Whey and Gold Standard Casein?
A: The main difference is absorption speed. Whey absorbs very quickly (ideal for immediately after a workout). Casein absorbs very slowly (taking hours), making it best for nighttime or long periods without food.
Q: Can I take this product during the day?
A: Yes! While it is marketed as a nighttime protein, it is excellent for controlling hunger during the day or bridging the gap between widely spaced meals.
Q: Does this texture differ from whey protein?
A: Yes. Casein naturally absorbs more liquid and has a thicker, creamier texture than whey. You may need to use slightly more liquid than you are used to with whey protein.
Q: Is this product suitable for baking?
A: Absolutely. Because casein absorbs moisture, it is excellent for baking protein brownies, cookies, or pancakes, ensuring they stay moist and fluffy.
