Essential part of recovery
For too long I had relied solely on whey protein to help build muscle, especially after intense work outs. It definitely helped, but often times I would wake up the morning after not feeling that much better. In other words, I wasn't really recovering that well. I considered just doubling up on the whey, basically eating another serving before bed, but then I did some research. I figured it would benefit me to alternate the types of protein supplement, and when I added the Optimum Nutrition Casein protein, it was a game changer. I now wake up in the morning feeling back to 100%. Even though I never train the same muscle groups two days in a row, I feel as if I could. I am making a 100% recovery in less than half the time. As a side benefit, the stuff tastes amazing. I mix mine with soy milk (yeah, I drink soy, get over it) and shot of light cream, after reading that a modest amount of fats help the body absorb large amounts of protein. Anyways, the vanilla is a very deep and satisfying flavor. To change it up I sometimes add some cinnamon powder, or some nutmeg and ground clove. On top of that, I eat it just before bed, and I am never super hungry in the morning, and I have eliminated my midnight snack routine. I use a hand crank egg beater to mix this stuff up, because even a little bit quickly turns into a thick mixture, sort of like wet concrete. It needs way more liquid to dissolve into than whey protein powder. Sometimes I also throw in some Greek style yogurt, but this stuff is thick enough already. The labeling says something about how Casein behaves differently when it hits the acid in the stomach, and that it expands, and you see this when you mix it up. If you have been missing something in the protein department, I would absolutely try this Casein. PROS: + Tastes awesome. + Fills you up, you feel satisfied, and won't be hungry for quite a while after. + A little powder goes a long way. + Slow absorption. CONS: - More expensive than most whey protein powders, but that's common to Casein.

Functionality and flavor are both good
I have specific health needs that require a high-protein, low-calorie diet, and this protein powder works perfectly as a breakfast meal replacement. I typically mix one scoop with 12 oz of 2% Fairlife milk and 8 oz of cold brew, which totals around 40 grams of protein. On its own, it provides 22 grams of protein per serving, making it easy to use multiple times a day to meet macro goals, even with just water. The flavor isn’t too sweet, and it adds a nice richness without a chalky texture. It also keeps me full from breakfast until my 1:00 PM lunch, even when I start my workday at 8:30 AM. For best results, I recommend using a good mixer bottle. My favorite is the Helimix 22 oz. That said, the powder dissolves well and doesn’t clump, making it easy to mix. Overall, this is a great choice for anyone looking to add quality protein to their diet without unnecessary calories or unpleasant textures.

Excellent brand quality protein
This taste a little bit different than your whey protein so it will take a little bit for you to get used to, but the benefits of it are great. I have seen some things about taking casein before bed and that's why I bought it. Great brand.

Good Source of Protein. East Digestion. Mixes well.
My doctor told me to get more protein into my diet, so I decided to try this. The taste is very good and it mixes into water & milk very well. Mixes in much better than whey protein. This is the vanilla and I am not a big fan of vanilla, but this is good. Carbs & sugar content is minimal, so this does not effect my blood sugar adversely. No problems with digestion or upset stomach. Could be used as a meal substitute, I suppose. I just wish it were less expensive.

Great slow digesting protein!
Great stuff, this is my first time using Casein instead of whey, taste is the same as whey, only difference is texture, Casein is thicker than whey, almost "milk shake" consistency when mixed with a half glass or less or water or milk. That said, stay away from the chocolate peanut butter, it's kinda nasty tasting especially in water, I like the Vanilla much better. As far as gains go, I have noticed all kinds of muscle improvements over the last month using this, Casein breaks down over a longer term than whey, about 3-6 hours so it's wonderful to take right before bed since that is when our bodies do the most protein synthesis/recovery, I noticed the improvements when I starting doing this. I actually did a custom blend of protein with this, I ordered a 1lbs tub of Whey at the same time then mixed it with the 4lbs tub of Casein, that way I get a little bit of fast acting protein when I use it for post workout.

Great protein powder!
I have been a longtime fan of this Casein Protein. It keeps me from getting hungry and I have not found a flavor I didn’t like. This blends well using just a shaker bottle. I usually mix with a couple additional ounces of milk than the directions call for, because that has gotten to be my preference. To each their own preference.

Never bothered with anything else :)
Great packaging, great results from the product! The taste is wonderful in this, the vanilla tastes like vanilla but kind of punchy and thick which brings out that flavour even more and I love that. On a muscle building point of view, this is a great product, every night I have it, I wake up the next day in a lot less pain or no pain at all. The vitamins and minerals in it are a great addition and the macro-nutrients from it including the caloric value are just perfect for me. Although I get a little bloated when I have it, I'm completely back to my normal stomach in the morning so no issues there as I can't tell when I'm sleeping. This is definitely must have product and especially this flavour over the rest. I've tried the other flavours and few other brands and till now this has been the best overall for price and results.

Muskelaufbau funktioniert
Ich bin schon Rentner und habe einen drastischen Rückgang meiner Muskeln gespürt. Bergab gehen hatte ich das Gefühl ich gehe auf den Knochen weil keinerlei Muskelunterstützung. Das hat sich sehr schnell geändert ohne Sport habe ich wieder stärkere Beine bekommen. Ich bin sehr zufrieden. Geschmacklich auch ok
