Optimum Nutrition Gold Standard 100% Casein Protein Powder, Vanilla, 24g Protein, 2 Lb

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.

I used to substitute for some meals and going through chemo and it helped greatly because I could keep the weight on on. I was losing weight all the time because I couldn't eat

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 💪🏽 just solid results and a shake I actually look forward to.

I feel great the next day after having a shake before bed.

All of these protein powders are getting so expensive but the price here was better than others I've found. Hubby's been using this for years and swears by it. It also tastes great!

I include a scoop of Optimum Casein with a scoop of Gold Standard Whey Protein as a part of my morning breakfast shake. . I find that it holds me until well after lunch without being hungry.

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.

Great taste and has helped build muscle!

This is one of the best tasting proteins I use. It is great for that last shake of the day. Slow digesting casein helps me recover while I sleep.

Creamy vanilla tastes like suntan lotion.
