## Description

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

Review: البائع غير أمين - المنتج كويس جداً بس تاريخ انتهاء الصلاحية يوليو ٢٠٢٤ حاجه فعلاً مستفزة
Review: Great product! ON Casein FTW! - If you're serious about bodybuilding, or at least about gaining muscle and being a regular at the gym, chances are that you've done your research on protein supplements. Whey protein is fast releasing/absorbing. If you are looking for a supplement before bed/meal replacement once in a while, casein might be the way to go. I've been buying this product for about 1.5 years now and I'm totally satisfied with it. Let me break it down a little bit. - It tastes GREAT! Almost like a smoothie. - It mixes well with water, milk, coconut water (lol). - Peanut Butter - Bread sandwich with a Casein shake - Oh lord, it tastes heavenly. - I take Whey protein as well, so I can't really quantify the effectiveness of casein separately, but I can tell you have I have gained considerable muscle overall and have been able to build some strength as well. - Post workout recovery has been quicker, in my opinion, since this is extra protein intake. - It's *slightly* more grainy than ON 100% Whey, but that's okay! I think it's reasonably priced. I'm a huge fan of optimum nutrition and I am a vegetarian. I can use all the protein I can get and I totally don't mind buying casein in addition to 100% Whey. PS: Casein + Plain oats taste great! I used to have oatmeal with Whey but thrown in Casein shake with regular oats, it tastes SO MUCH better, I actually enjoy having oatmeal.

## Questions & Answers

**Q: why this product wont dissolve in milk? i shake it over 30 second and i can still taste the powder so thick**
A: There’s your problem, shake for 45 seconds. You’re leaving all those reps on the table. Remember, explosive out but a controlled return. 12 shake reps should take you 45 seconds if you’re doing it right. And breath. Contract. Feel the muscles. Quit leaving those reps on the table.

**Q: does this have gluten in it**
A: Although it maybe doesn't have gluten, people with gluten sensitivities or Celiac Disease should avoid the enzyme, Casein. I have Celiac Disease and this would "kill" me!

**Q: My container did not have a scoop in it. How much powder to I use for a shake?**
A: It's approximately a 1/4 of a cup (not exactly), but I'd bet there's a scoop in the bottom of the container somewhere, they sometimes sink to the bottom of the container...  It's placed in these containers by a computer system, not a person so chances of a mistake are minimal.

**Q: Does anyone know if this is 100% Micellar?**
A: No, it has calcium caseinate as the second protein source.

### ⭐⭐⭐⭐⭐ Great Taste and Excellent Slow-Digesting Protein
*by F***N on 28 December 2025*

I’m a huge fan of Optimum Nutrition whey, and this product did not disappoint either. The powder dissolves easily and mixes smoothly, with a chocolate flavor that tastes really good — definitely enjoyable to drink. One thing to keep in mind is that this casein requires more liquid per scoop compared to whey to achieve the desired consistency, but that’s typical for slow-digesting proteins. It works perfectly for overnight muscle recovery and helps keep you full longer. Overall, a high-quality casein protein that delivers on taste, mixability, and effectiveness. A reliable choice for anyone looking to support muscle recovery or stay satiated overnight.
