Product Information

📋 Directions for Use

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. 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 more body and sweetness, mix each scoop with 4-6 oz of water, milk or your favorite beverage. For a milder tasting, less sweet shake, use 8-10 oz of liquid per scoop. Shaker Cup: Bringing a shaker cup with you to the gym is the best way to get a dose of protein immediately after your workout. Just pour 6-8 oz of your preferred beverage and then add one scoop of Gold Standards 100% Whey to your shaker cup. Cover and shake for 25-30 seconds. Blender: Add one scoop of Gold Standard 100% Whey to a blender filled with 6-8 oz of water or your favorite beverage. Blend for 20-30 seconds. Then add 1 or 2 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 it even more delicious shake. Stack your Shake: You can make Gold Standard 100% Whey an even better post workout product by adding supplements like creatine, glutamine, BCAA and concentrated carbohydrate powders. Think outside the glass: Gold Standard 100% whey can be used for more than just protein shakes. Try mixing a scoop into oatmeal, yogurt, or the milk that you pour over your morning breakfast cereal. Better yet, increase the protein content of muffins, cookies, brownies, etc. by adding a scoop or two to your baked goods. Suggested Use: For Healthy adults, consume enough protein to meet your daily protein requirements with a food combination of high protein foods and protein supplements throughout the day as part of a balanced diet and exercise program.

🧪 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.

Beyond the Basics 75% Protein by weight (24 g of protein per 332 g serving size) Whey protein Isolates (WPI) Main ingredient.
