About this item
Product details
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 for hours without food. Casein products are acid sensitive and thicken in the stomach. Compared to some other proteins, it can take longer 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. 24g of Micellar Casein
24g of Anti-Catabolic Micellar Casein, Nearly 5 Grams of Naturally Occurring BCAAs per Scoop, and Nearly 5 Grams of Naturally Occurring Glutamine and Glutamic Acid per Scoop

Instructions
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 to your shaker cup and then pour in 10-12 oz of your preferred beverage. Cover and shake for 25-30 seconds. Adjust the intensity 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.

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. ā From a long-time loyal customer.

Slow Burn, Big Gains š„
This casein protein is my go-to for overnight recovery. Smooth texture, no chalky drama, and it keeps my muscles fed while I sleep. Whether I'm deep in prep or just keeping it tight, it's the kind of clean, slow-digesting fuel that actually works. Plus, there's no bloating and no weird additives šŖš½ just solid results and a shake I actually look forward to.

I absolutely love Optimum Nutrition Casein! It mixes smoothly, tastes delicious (especially the vanilla flavor), and keeps me full all night. As someone who struggles with late-night cravings, this slow-digesting protein helps me maintain muscle and avoid unnecessary snacking. It's easy on my stomach, doesn't cause bloating, and delivers 24g of high-quality protein per serving. The value for money is excellent, and I've noticed better recovery since adding it to my routine. Highly recommend for anyone looking for a reliable nighttime protein.
