      • Supports muscle recovery
      • 24g of protein & 9g EAAs per serving
      • Slow-digesting
      • Chocolate Supreme flavor

      Fuel your goals even as you sleep with GOLD STANDARD® 100% CASEIN™ by Optimum Nutrition. This slow-digesting formula delivers 24g of premium micellar casein, plus 9g of EAAs to refuel recovering muscles when your body goes for hours without food—like at bedtime.

      Frequently Asked Questions

      What is micellar casein protein?

      Micellar casein is a milk protein that is digested more slowly than other proteins, providing an extended release of muscle-building amino acids that help prevent catabolism.

      What is catabolism?  

      Catabolism is the breakdown of protein. When your body goes for extended periods without food, or when it’s under significant metabolic stress during exercise, it can resort to catabolizing your muscles for energy.

      Read More

      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 to a shaker cup filled with 10-12 oz of your preferred beverage. Cover and shake for 25-30 seconds.

      Warning

      Allergen information: This product contains milk and soy (lecithin) ingredients. Store in a cool, dry place. Contents sold by weight not volume.

      Customers review summary
      This is an AI generated summary of reviews and may include incentivized reviews. This summary pulls themes from recent reviews and may not reflect every individual experience.

      The Optimum Nutrition casein protein powder charms customers with dessert like flavors and a thick pudding texture that makes it feel like an indulgent bedtime shake. Its slow release protein helps muscle recovery overnight while chocolate and vanilla varieties blend into creamy shakes, smoothies, or even puddings that many customers enjoy. A few customers note occasional clumping or a gritty mouthfeel, but most report it curbs late night hunger and supports overnight recovery.

      Bad service
      I signed up for the mailing list because they offered a discount coupon for doing so. I ordered this product to pick up at my local store which had it in stock. After placing the order the store proceeded to cancel my order. I tried to reorder the item for delivery but the coupon has "already been used." I will unsubscribe and shop somewhere else.

      Casein
      Years ago when I was living in Turkey, I always liked this brand. Even though Optimum was way more expensive than other supplements, I still tried to buy it because it was my favorite. But unfortunately, not all of their products were available in Turkey.

      Now that I live in the U.S., I'm always an Optimum customer. After using it for so many years, I know they make the best and most effective sports supplements.

      - From a long-time loyal customer.

      Solid
      Been taking this casein for a few years (took a break going into college) and it does the job. I've seen muscle gain and weight loss consistently while taking it. It's a little hard to get down when you start but that's the norm with these powders. Tastes solid enough too.

      Very impressed
      I wasn't sure what to expect because I usually only buy whey protein. This is delicious. I'm very happy to say that it exceeded my expectations and will buy again regularly.

      How do you mix the powder enough so you than you cannot feel the texture of the powder?
      A shopperJun 5, 2013

        follow the directions on the label, 6-8 oz of water should do the job for one scoop. If you are mixing more tha one scoop with water, go 6-8 oz to each scoop. Try mixing for 15-25 seconds.

        I only mix casein protein in lowfat milk and I use a shaker cup with one of those metal shaker balls in it. It tastes good and there are no chunks.

        Use a blender for best results, with either milk or water and ice. Blend for at least 1 minute for ideal texture

      Anyone have issues with the belly? I'm borderline Lactose Intolerant so wanted to know if anyone has had problems?
      RobertApr 26, 2019

        This would depend on the individual. Casein proteins contain little to no lactose. Please also feel free to consider looking into some dairy-free protein powders - Theresa K. (VS)

        I’ve had no issues with this. I’m not lactose intolerant, but during training I remove dairy and when I bring it back in I get “borderline” as well. Never had a problem with this casein. I mix it with almond milk and it makes a great “pudding”.

        Frequently Asked Questions

        What is micellar casein?

        Micellar casein is a milk protein that is digested more slowly than other proteins, providing an extended release of muscle-building amino acids that help prevent catabolism.

        What is catabolism?

        Catabolism is the breakdown of protein. When your body is under significant metabolic stress - like during high-intensity interval or resistance training - it can resort to catabolizing your muscles for energy.

        What is the best time to take BodyTech Micellar Casein Protein?

        For the best results, this great-tasting protein powder should be enjoyed immediately upon rising, after a workout, or before you go to bed to help protect your muscles from catabolism.

        What is Aminogen?

        Aminogen is an enzyme that helps your body digest and absorb protein.
