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.

Recovery ability		It's a slower digesting protein so you take it at night and your muscles recover and build while you sleep.


Taste		I have been taking this for a few months now and I have to say that it tastes really good!


Texture		So,I bought this casein for my night recovery.It was banana taste and I can say that it was awesome : so thick and delicious.Yeah,I was waiting for my evening every day :) You can ask me about recovery.I felt this product.I can compare ON casein with dymatize and ON is much better!Dymatize has too much lumps and mix bad.

Texture		only downside to this the grainy/thickness of it which some ppl love
Suppressed appetite		i bought this in order to feed my body while i cant have full meals or when sleeping, it worked great i dont wake up hungry anymore and this will keep you full for a few hours.


Taste		good taste pretty clumpy
Mixes well		good taste pretty clumpy


Texture		however, I never found out because it taste horrible(thick).
Texture		I tried it with milk, water, and smoothie.
Texture		It is overly thick and upset my stomach.

Physical energy		I wake up feeling energized and it takes care of my craving for something sweet.


Texture		but I HATE the grainy texture of the casein protein when mixed with just water.
Mixes well		but I HATE the grainy texture of the casein protein when mixed with just water.
Mixes well		Clumpy, difficult to mix (with a spoon, with a mixer, etc.), and almost sand-like.
Ingredient profile		Good BCAA profile as well.


Taste		Does not mix well at all, and the taste is horrible.
Taste		but I'll probably try another Casein to see if there is something with better taste and that mixes better.

Taste		Great product it's my final meal of the day great tasting and effective slow digestive protein , also good if you wake up in the middle if the night , quick shake and it's protein sustained protein for hours


Taste		I've been taking ON casein for one year this summer, and I can honestly say that I have seen improvements in my physique, which can at least slightly be attributed to the extra protein provided to me before bed via casein (I also like to add half a scoop into my post-workout shakes, makes it taste better if you have the Chocolate Supreme, and it's more protein!).
Taste		HOWEVER Please note that that chocolate peanut butter tastes awful.
Taste		It tastes exactly like the chocolate supreme does,
Taste		but with an additive that I think was intended to mimic the taste of peanut butter.. it just tastes like chemicals.


Texture		Mix the milk and Casein together first until it's smooth, then, add the Almond or peanut butter and mix until smooth, toss it in the freezer for 10-15 minutes.
Taste		Definitely my favorite flavor!
Mixes well		Mixes well as long as you experiment with different mixes.


Texture		It's ability to dissolve in liquid is severely lacking, whether it freshly, made or given a few hours, it retains a gritty texture which honestly caught me off guard after using the Whey protein isolate I use, which dissolves perfectly.
Taste		The other issue I found was an after taste that lasted for a while, usually requiring a few glasses of water to get rid of...which in hindsight is probably a good thing, drinking more water is always good...but that shouldn't be the reason you drink more water, y'know?

Taste		Tastes Good.
Mixes well		Mixes Good.
Value for money		However, it is expensive.


Taste		but the taste is not my favorite.
Mixes well		It mixes very well for a casein


Texture		Love the texture of it and ever since I started using it gains have been noticeable.
Value for money		A great product slightly pricey compared to other caseins,
