Sometimes slower is better - especially when it comes to the rate of protein digestion. While rapid protein absorption is desirable immediately before or after exercise, delayed release is probably more beneficial throughout the remainder of the day.

Casein proteins are pH sensitive and gel in the acidic environment of the stomach. As a result, it can take more than twice as long for caseins to be broken-down into their amino acid sub components than whey and other proteins. Because of these unique "time-released" qualities, caseins are aptly described as being anti-catabolic, or muscle-protecting, proteins.

Muscle gain


Taste		Tastes Gross alone in cold water.. Ok in warm water.. and pretty good if you mix with oatmeal.


Taste		Although I prefer the flavor of the chocolate whey,
Taste		the chocolate supreme Casein tastes great too.
Taste		The taste is great and, because I mix it with Lactaid or some other form of lactose free milk, it doesn't give me gas.


Muscle gain		Along with other supplements I gained 20 pounds of muscle.


Taste		I have to say this is my favorite protein supplement it's so rich in taste and filling.
Taste		Chocolate lovers the taste won't let you down.
Anti-catabolic		I have to make sure I am keeping my body full of nessacary bcaa's and proteins at all times even while I'm off in sleepy land to keep those hard earned muscles from being used as fuel for my body.


Taste		but the taste wasn't so good
Taste		but i still like a lot just not this flavor


Texture		It is almost impossible to get smooth (even in a shaker cup) and spoon stirring it is not even worth the time.
Taste		I bought this product really hoping to find a great fruit flavored protein i could take at night with water.
Taste		It clumps terribly and the taste is average at best.
Mixes well		It clumps terribly and the taste is average at best.


Muscle gain		Since i have a very fast metabolism i gain muscle as easily as i lose it so i must be filled with protein.
Taste		Great taste, great product!


Texture		It is very thick like a shake with about 8 ounces of milk or is more like a chocolate milk when mixed with 16 or so ounces.
Fat loss		To be honest I did notice myself leaner in the morning after taking this before bed,
Taste		I can't stress enough how great tasting the Chocolate Supreme flavor is.
Mixes well		It is very thick like a shake with about 8 ounces of milk or is more like a chocolate milk when mixed with 16 or so ounces.
Value for money		Overall I would highly reccomend it if you have the money,


Taste		great taste, my favorite night protein right before bed and between 2-3am I'm having another one.


Texture		My first pure casein product and it takes a while to get adjusted to the different texture.
Texture		Considerably thicker than whey and it doesn't mix as well.


Taste		yummmmy


Strength		I use it after each weight-lifting workout to build strength.
Taste		Best tasting by far.


Taste		I've tried several other brands and nobody else has this good of a taste, with this simple of a product, for this good of a price.
Taste		This protein is delicious and mixes extremely well in a shaker or even a water bottle, in a pinch.

Texture		Well, this protein powder is supposed to be a lot thicker than normal whey aniway so no complaints.
Taste		The taste is really good and the mixability
Mixes well		The taste is really good and the mixability


Texture		It seems to have something to do with the consistency of it.
Texture		Even with water, it gets pretty thick,
Taste		On the downside, I still haven't found a flavor of casein that is "great."
Taste		I'm going to keep sampling new flavors as they come out to try to find one that works,


Texture		Aside from the lumps, the texture is like that of a milkshake and it does go down smooth.
Texture		It goes down pretty smooth, tastes good, and does its job which is all I think one can ask for.
Taste		The taste for me is awesome.
Taste		It goes down pretty smooth, tastes good, and does its job which is all I think one can ask for.
Value for money		I ended up buying a case of this, and then reading reviews afterwards before I got home and thought I might had wasted my money.
Value for money		Bottom line: the product is definitely worth the price.


Taste		I bought ON Casein Chocolate Supreme and thought that it would taste very good like the ON Gold Standard 100% Whey Double Rich Chocolate
Taste		but unfortunately it tasted awful!
Taste		I threw more than the half away because of the terrible taste!


Taste		I would prefer buying buying higher power casein compared to this one... taste wise as well as profile wise
Ingredient profile		I would prefer buying buying higher power casein compared to this one... taste wise as well as profile wise


Taste		The big drawback for me was the taste(5/10), I feel like it tastes like chemicals and I usually have to force it down.
Taste		Other than the taste I love it!
Mixes well		but you just have to put the powder in slowly and carefully and it mixes fine.... sometimes when I just dump it in fast it tends to form chunks and makes it difficult to mix.
