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

    Probably thee BEST protein out there. For those in the weight room regularly with a good diet this , for me, is a night time protein. I try to eat every 2-2.5 hours. So I have one ready for when I get up in middle of the night. What a slow digesting protein is for. Yes you can have a regular shake immediately after a workout, however in my opinion that’s when a solid meal is necessary. I like having a jug of the Casein when I’m in the weight room regularly.

    My husband really loves this company and protein powder brand. This one I got for him to help him feel fuller because he’s an over eater and this seems to work. It’s also great for his working out so very please as always with Optimum nutrition. The taste is really good my husband said and it blends very well since I am the protein shake maker of the house.

    What I love about casein protein is it keeps you full and absorbs slower than whey. I usually drink it before I go to bed, and it’s so thick it’s like drinking a shake, even when blended with just water. Makes me sleepy for bed, too . And since I like to keep track of my macros, this is a great way to add some extra protein if you realize you’re falling short. Will buy again.

    This product has been extremely consistent over the last year. It is a little clunky and hard to mix. Some people recommend blending it but I find that it gets too foamy. If you care about a smooth silky taste then shake (or blend) this product several hours before you use it and let it sit. That’s the best way I have found to get the casein to properly settle.

    Great product from ON. I have seen reviews complaining about the consistency and chunks… this ie Casein protein.. it becomes a gel in your stomach for slow consumption while you sleep. I find that if you pour the water/milk FIRST, then dump the scoop in the cup and shake it well, you are good. However. If you throw the powder first then the water/milk, it has a tendency for a good portion to solidify in the bottom of the cup/shaker.

    Mixes great in a shaker with water. It doesn’t have a strong chicolate flavour but it doesn’t taste too bland either. Definitely worth trying!

    THE BEST protein powder I have used (and I’ve researched the hell out of them). No issues digesting it. Filling. Tastes great. Quality natural ingredients. I recommend anything from this brand 100%.
