Product Information

📋 Directions for Use

Directions: Using a shaker cup is the easiest mot convenient way to mix up a consistently great casein shake every time. Just add one heaping scoop of Gold Standard 100% Casein to a shaker cup filled with 10-12 oz of your preferred beverage. Cover and shake for 25-30 seconds. Tip: Adjust the flavor and texture of your Gold Standard 100% Casein Shake by varying the amount of liquid you use to prepare it. For a bolder flavor with a slightly thicker body and more sweetness, mix one scoop with 8-10 oz of water, ,ilk or your favorite beverage. For a thinner, milder tasting, less sweet shake, use 12-14 oz of liquid. Don't have a shaker cup? Visit optimumnutrition.com and order a custom shaker, or visit your local health food store or gym. Blender: Add one heaping scoop of Gold Standard 100% casein to a blender filled with 10-12 oz of water, milk, or your favorite beverage. Blend for 20-30 seconds. Then add 3-4 ice cubes and blend for an additional 30 seconds. Shake up your shake: By adding fresh or frozen fruits, peanut butter, flaxseed oil, coconut and other ingredients, you can make even more delicious shake. Stack your shake: Customize your gold standard 100% Casein shake by adding recovery products like creatine, glutamine and BCAA Powders. Spoon Stirred: If you forgot your shaker cup or don't have time to get out the blender, you can just add one heaping scoop of Gold Standard 100% Casein to a glass filled with 10-12 oz of cold water, milk or your favorite beverage. Then mix it up with a spoon for about 30 seconds or until powder is dissolved. Suggested Use: Consume enough protein to meet your daily protein requirements through a combination of high protein foods and protein supplements. For the best results, consume your daily protein allotment over several small meals spread evenly throughout the day.

🧪 Formulation Notes

The True Strength of Casein Faster digesting protein is desirable immediately before and after exercise to help refuel recovering muscles, but slow digestion and absorption may be more beneficial at other times-including bedtime when your body typically goes to for hours without food. Casein proteins are acid sensitive and thicken in the stomach. Compared to some other proteins, it can take more than twice as long for our Gold Standard 100% Casein to be broken down into its amino acid subcomponents. By using only premium micellar casein as a protein source, we've created a formula that sets the standard for slow digesting protein support.
