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™ 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, milk or your favorite beverage. For a thinner, milder tasting, less sweet shake, use 12-14 oz of liquid.

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 an even more delicious shake. Stack Your Shake: Customize your Gold Standard 10% 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.

Use this product as a food supplement only. Do not use for weight reduction. Intended for use by healthy adults over the age of 18. Store in a cool, dry place.

Product Information

Beyond the Basics

  • Best-Selling Micellar Casein
  • 75% Protein by Weight (24G of Protein per 32G Serving Size)
  • 24 Grams of Slow-Digesting Micellar Casein per Serving
  • Over 5 Grams of BCAAs (Leucine, Isoleucine and Valine) per Serving
  • Very Low Levels of Fat, Sugar & Carbohydrates
  • Ideal for Use Between Meals and Before Bed

Sometimes slower is better - especially when it comes to the rate of protein digestion. While rapid protein absorption is desirable directly before or after exercise, delayed release is probably more beneficial throughout the remainder of the day and night time.

Casein proteins are pH sensitive and gel in the acidic environment of the stomach. As a result, it can take more than twice as long for caseins to be broken-down into their amino acid subcomponents than whey and other protein sources. Because of their unique time-released traits, caseins are aptly described as anti-catabolic or muscle-protecting proteins.

Casein protein is ideal for use in between meals and before bed. Casein protein is sometimes known as "night time" protein because it's ideal to have just before you go to bed.

Does not mix well. Does not taste good. I believe there has to be a better casein protein out there than this.*

Calls to mix with 10-12 oz liquid, any less and its pudding. This stuffs thick! I usually stick to plain vanilla cause its the most versatile with smoothies and yogurt but this vanilla was a little off. To me it has a hint of coconut, almost like a pina colada and I dont like coconut. I mix with water now to not enhance flavor with milk, also use a blender stick to make it smooth. Quick chug before bed and Im full with good protein. Overall 4.5 stars because the stuff woks but taste is bad and Im mainly looking for performance.*

First casein I've bought and will be the one I stick with. Keeps me full for hours and don't wake up feeling totally empty. Taste great, little thicker then other shakes but isn't a problem at all for me. I take mine down in a shaker bottle and comes out smooth'm big on ON products and this one didn't disappoint.*
