Casein Protein Gold Standard Description Recommended Usage Reviews

100% Casein Protein Gold Standard
Time Released Casein Protein Powder

Check out more commercials

100% Casein Protein Gold Standard is a slow digesting protein powder. 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 subcomponents than whey and other proteins. Because of their unique time-released qualities, caseins are aptly described as anti-catabolic or muscle-protecting proteins.

100% Casein Protein Gold Standard Highlights:

24 g of Highly Anti-Catabolic MICELLAR CASEIN
10 g of BCAAs, Glutamine, and Glutamine Precursors per Scoop
AMINOGEN Enhanced

Note: Nutritional Profile Varies Slightly By Flavor

Comments:	I purchased the creamy vanilla, and the biggest knock on it I have is that it was extremely foamy. The taste was good and with this, glutamine, BCAAs, and whey I was able to put on about 10 pounds over the summer (175 to 185) and added about 100 pounds to my 3-lift total. Will buy again and would recommend to anyone.

Comments:	Good protein for late night as stand alone or in addition to cottage cheese etc. Got the blueberry flavor and wasn't crazy about it. Won't get this flavor again. Caked up in my shaker and was foamy.

Comments:	Great quality protein, i drink it before bed which keeps my stomach busy for the night, it is a slow release protein so your getting nutrition while you sleep. Mixes pretty easily, i use a shaker cup and i recommend putting a little bit of water or milk in the bottom first, this way it doesn't stick to the bottom, then the rest of the liquid in on top of the protein. Also the taste is really good for protein, not hard to drink at all. i usually stick with the chocolate.

Comments:	Honestly wasn't too impressed with the flavor everyone raves about, BUT it is quality micellar casein and that is the important factor. So 4 it is, I'm not going to give a garbage rating just cause the taste isn't off the charts.

Comments:	Blueberries and cream is the best! Ive tried tons of different casein proteins over the years, and this is by far the best one I've had yet! The blueberry tastes great and goes down smooth, and its not chalky at all! Mix it with milk though, not water! I take it right before bed and it holds me over to the morning better than anything else I've ever taken! Gained about 2 lbs of muscle too since i started using regularly! I love it! Will continue to buy! :)

Comments:	It is a good product, the flavors are OK, many are down right terrible but the basics like chocolate, French vanilla, etc. are good. Product is getting too expensive. We are looking for similar quality but lower priced alternative. I have been buying ON products since the 90s when they were not advertising or sponsoring and were very affordable. Not affordable any more.

Comments:	Great slow digesting protein. The chocolate tastes the best to me. I used to take before bed but started noticing weight gain. Since I work out first thing in the morning, I started taking it as a post workout shake in conjunction with whey protein to sustain me throughout the day.

Comments:	I never review products based on taste....but the Raspberry has me making an exception. The only way to describe it is awful. It tastes like cough medicine. I have to force it down every night, only because it IS a great protein. Please listen to me and avoid at all costs!!! I do, however, absolutely love the chocolate and the Blueberries and Cream!!

Comments:	I purchased the raspberry flavor. It was not what I expected. It does not mix well in water using a shaker cup. I had to use a blender with milk to get rid of the chewy bits of casein. Yuck. Needless today I still have a lot left .

I like all the flavors but the cookies and cream is my top choice. I've combined it with the whey after my workouts and at bedtime for the sustained protein feeding my muscles need. ON is numero uno

Comments:	This is a great protein to take right before bed. I have a BAD SWEET TOOTH so what I do right before bed is put 1 serving in a cup with a drop of cold water. Mix it slowly at first adding small amounts of water until a pudding consistency is reached. Once you reached your desired consistency give it a couple of quick powerful stirs to fluff it up, throw a small shot of LIGHT whipped cream on top and you got a 24g casein protein pudding right before bed. It will not only hit the spot if you h

Comments:	A really thick protein. I don't enjoy as much because keeps me up if take an hr before bed. Don't stack with other proteins at same time because slow digesting. I made that mistake. Leaves you bloated and full at night, but digests as says over night. Doesn't blend easy and messy to clean up unlike whey. There are a lot of other slow digesting proteins I'd try 1st.
