    * I have tried many different brands of casein, in particular chocolate flavour & would have to say this is the best tasting. It's a smooth consistency & not too sweet but sweet enough. I highly recommend this casein.

    * LOVE the chocolate, doesn't mess with my blood sugar, keeps me going, I don't get hungry! I have ONE HUGE QUESTION: I'd like to order Cappuccino! When is Cappuccino coming????????????

    Editor's note: Cappuccino flavor is not available in the Casein Gold Standard protein. However, there is a Mocha Cappuccino flavor available in the Whey Gold Standard protein.

    * This is the first time I tried Casein protein and I LOVE it. I get bloated with whey...not with this. So happy!! I bought the chocolate peanut butter and it's quite good. Will try vanilla next. I too have a shake at night before bed.

    * This has been my night top protein of choice. I followed the other reviews and mix 1 scoop of vanilla with 10oz of water, ice cubes and a tbs of peanut butter. This is such a treat every night...could drink this all day. I am severely lactose intolerant and me wife has Celiacs...we both enjoy this every night with no issues. Amazing protein.

    * Great flavor suitable for use with flavorings. I use it in the Netrition shaker half water, two tablespoons real sour cream, 1/3 tsp xanthan, two scoops of protein and crushed ice. (As a treat I may add two tablespoons tahini and a capful of rose water). Needs a good shaking, but makes a good lasting breakfast.

    * My favorite casein. I normally have stomach issues with casein but this doesn't bother me. Also I like to mix just enough water and it turns into pudding.

    * I never review products, but this is the best protein supplement I have ever tasted. It doesn't taste very good with water, but it's really great with 1% milk. It makes your workout a breeze and keeps you full.

    * This mixes pretty well for casein. I have found that the best way to avoid it sticking to everything and getting balled up is to do the following. Fill shaker cup with water and about 4 large ice cubes, then put protein in and shake violently. Just like the shake weight commercials.

    * I guess no one bothers to read ingredients. Everyone is so amazed at how thick this amazing protein gel is! Well guess what, it has xanthan gum and other gums in it. Of course it gels up, and not because of the casein.

    That said, it's quite tasty (especially for casein, which can be rather horrid, so this brand is nice) and much more satisfying than whey. The ability to just add water and have a nice pudding is such a boon. Great on the go.

    * Great protein-to-calories ratio. Optimum Nutrition casein is easily the best tasting, easiest to mix casein protein on the market. That said, it still works best to use a shaker. I buy the "chocolate peanut butter" and "chocolate supreme." Both are yummy.

    * It took me a while to get used to casein but once I did I loved it. It does taste MUCH better with milk! I blend it with ice and make a little smoothie out of it. It really fills me up! I have only tried the blueberries and cream flavor, but I'm sure they all taste pretty good.

    * Great product for bed-time. I always drink it with skim milk. "Banana Cream" doesn't taste very good but after a while you get used to it. "Chocolate Supreme" tastes a bit better. It might not mix very well if you don't have powerful blender and it is difficult to mix with a shaker.

    * This is by far my favorite nighttime/slow-digesting protein. My favorite way to have it is in a protein shake with peanut butter. I make one almost every night before bed. Here's my recipe:

    - 1.5 servings/49g Chocolate Supreme Casein Powder (I weigh it on a scale, don't trust scoop sizes) - 4oz Milk (more if preferred, I try to slim on down on the cals) - 9oz cold water - 2 tbsp peanut butter (omit if you don't like)

    Blend that up for a few seconds, then add some ice cubes and blend again. Its such a delicious shake, reminds me of the chocolate blasts I used to buy at Baskin Robbins all the time. Delicious!

    * I call casein "protein gel" but it's the best for bedtime.

    Banana is tasty!

    Chocolate Peanut Butter is OK, and relatively true to its name.

    This protein sticks like glue to glassware if it has dried out even a little. Even my dishwasher can't get it all off. (I didn't notice this with the banana but maybe I just didn't see it.)

    * The Chocolate Supreme flavor casein protein is delicious and has real chocolate flavor. I can drink this almost every single day, and not get tired of it. I mix it with water and add a splash of half & half to add to the creaminess. Really helps cover any cravings for chocolate and sweets, as well. Optimum Nutrition is really making good stuff when it comes to protein, IMO.

    * I had a smaller tub of the cookies & cream and it was delicious, even with water. I ordered a big tub of the banana cream, and yeah.. not so much. I wish I went with the C&C. Still have to try the others. Great casein protein though. Top notch!

    * This protein powder tastes great, mixes very well with milk but not too well with water. I usually take it just before bed at 11 and wake up at 7 not feeling too hungry. On days that I skip the shake, I'm starving in the morning, so it does make a difference.

    * I got the banana. It takes a lot of liquid to get this stuff into a drinkable consistency, and it has a very poor taste when you mix it with a lot of water. Mixing it with less water means it is thicker, harder to mix, and has more flavor, but just plain tastes bad... I actually gagged a few times choking this stuff down. It certainly doesn't mix well with a shaker. I usually prefer chocolate, so that may be my problem. I certainly won't be buying any banana flavored stuff again.

    * I ordered the chocolate and the banana flavor in this product. I am disappointed in the taste of this product. I have prepared the chocolate two times and still cannot come up with a good flavor--even after adding splenda, cream, and 1 TB Nestle's sugar-free chocolate mix to it. Very bland taste. I added only 1 cup of liquid, so the "flavor" isn't diluted. If anyone has any suggestions as to how to make this "tasty," I would appreciate hearing them. I gave it 2 points, instead of 1, because it contains 24 Grams of protein in a serving. I haven't tried the banana flavor, yet, and hope it will be better.

    Creamy vanilla tastes just like a vanilla milkshake, but yet it is good for you (unlike a real vanilla milkshake). I couldn't taste any aftertaste either. This stuff's the best!!!!!!!!!!!!!!!!!!!

    * Hands down, the best tasting protein I've ever had. Just beware, this is extremely thick, one scoop turns into a pudding-like consistency in 1 cup of liquid, so you need at least 2 cups of liquid to make it 'flow' out of the glass; but then the excellent flavor will be diluted -that's why I prefer to use 1 cup of liquid and eat it with a spoon. I like to sprinkle some cinnamon to top it off. Doesn't need any extra sweetener or flavoring. It's just great as it is. 100% recommended.

    * Great product - I used to use 2 scoops of the Optimum Nutrition 100% Whey protein on my breakfast cereal (1 cup rolled oats with a little granola for crunch), and I was starving by 11:00 am. Now I use one scoop of this and one scoop of Whey (both vanilla). The Casein burns slower and carries me through until lunchtime with plenty of energy and no hunger pangs. Its the perfect breakfast.
