Directions & Suggested Use
Suggested/Recommended/Usage/Directions
SUGGESTED USE: Consume approximately 1 gram of protein per pound of body weight per day through a combination of high protein foods and supplements. For best results, consume your daily protein allotment over several small meals spread evenly throughout the day.
Suggested/Recommended/Usage/Directions
DIRECTIONS: Using a shaker cup is the easiest and most convenient way to mix up a consistently great casein shake every time. Just add one heaping scoop of Gold Standard 100% Casein(TM) to your shaker cup and then pour in 10-12 oz of your preferred beverage. Cover and shake for 25-30 seconds. TIP: Adjust the intensity of your Gold Standard 100% Casein(TM) by varying the amount of liquid that you use to prepare it. For a bolder flavor with slightly more body and sweetness, mix one heaping scoop with 8-10 oz of water, milk, or your favorite beverage. For a milder tasting, less sweet shake, use 12-14 oz of liquid per scoop.
Suggested/Recommended/Usage/Directions
BLENDER: Add one heaping scoop of Gold Standard 100% Casein(TM) to 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 a few high-energy ingredients to your shake you can blend up a delicious meal; try adding fresh or frozen fruits (strawberries, bananas, peaches, etc.), peanut butter, flaxseed oil, yogurt, coconut, slivered almonds, or other ingredients.
Suggested/Recommended/Usage/Directions
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(TM) 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.

THE BIGGER PICTURE OF CASEIN Rapid protein use is desirable immediately before and after exercise to help fuel recovering muscles, but delayed digestion and absorption may be more beneficial at other times - including bedtime when your body typically goes for hours without food. Casein proteins are acid sensitive and thicken in the stomach. Because of this, it can take more than twice as long for our Gold Standard 100% Casein(TM) to be broken down into its amino acid subcomponents than other proteins. By using only premium micellar casein, we've created a protein formula that's truly time-released.
General Statements: All Other Content
TIP: Try using "slower" Gold Standard 100% Casein(TM) with "faster" proteins like Gold Standard 100% Whey(TM) or Pro Complex(R) at different times for maximum effectiveness. Take Gold Standard 100% Casein(TM) immediately before bed and in between meals when delayed protein delivery is desired. Drink Gold Standard 100% Whey(TM) or Pro Complex(R) proteins before and immediately after workouts for a rapid "shot" of amino acids.
