I used to take whey protein before bed for recovery and growth but lately my recovery times have been taking too long. This Gold Standard Casein works very well with over night muscle recovery. I mix one scoop of the Casein with a Gatorade sized bottle of milk, shake it, and drink it. Over all it does what i wanted it to, help me recover faster. (Posted on 1/5/12)

Casein is a great, long-lasting protein, perfect for right before bed as its aminos are release more slowly than whey. Casein, in general, is bland (think no fat, no salt, cottage cheese), and harder to mix than whey. Optimum Nutrition has here a decent casein, that is not too bad tasting and mixes better than most every other casein I've tried. The price is ok, but I'd like to see it cheaper (who wouldn't?). I mix it with whey and use it throughout the day. I have tried and rejected the chocolate flavor. (Posted on 1/5/12)

I love this product. Optimum Nutrition does a great job with most of their produts and this is no different. The taste isn't as good as regular whey proteins but there really isn't anything that can be done about that. Casein is a slow digesting protein that usually lasts about 7 hours which makes it a perfect for night time. Highly recommended (Posted on 1/5/12)

Yes I am science Guy so I would like to bring some scientific viewpoint, trying to keep my review Jargon free, or very simple for the least.


1. Do I need Casein Supplement.

Almost every Human being can benefit from Casein, however everyone DOES NOT need a Casein supplement. I would recommend this supplement only who is at intermediate or advance fitness levels (rest will do good with cottage cheese- provided you relish it). If you are a beginner, please stay from pure Casein supplement, its not the starting point by any mean and you will not get much benefit out of it. Beginners are better off with Whey only or blend supplements.

2. Hey is Casein better than Whey?

Yes and No. The big question is compared to What. If one is looking for a general protein source, then NO way. Caesin is not a well rounded and balanced protein, it is a specialized protein. In other words, its Amino Acid profile is not balanced. Its inclined towards recovery ( high Glutamine and Anti Catabloic properties). Lastly its Biological value is only 77 compared to 104 of Whey.

However, what it does for the body, no other protein can. It digests very very slow and release rich amount of Glutamine and other Amino acids which helps you recover and stay Anabolic.


3. What is Special about ON Casein

First and foremost, its not exactly the most delicious and consistent protein by nature. Nothing that ON can do to change it, this is the nature of Casein. But, what ON does is that it gives you the best of Casein, the Micellar Casein. Making it the best Casein protein supplement in the market.

4. Whats the heck with Casein and Why is Casein protein more expensive than Whey?

This is a fair question since, out of all the protein in Milk, 80% is Casein and 20% is Whey. This means Casein should be cheaper. ...Not exactly, out of the total casein, only limited amount of Casein is Micellar Casein. The one which is ideal for a protein supplement and definitely the most effective. The cost of extracting Micellar Casein is way more than Whey.

Therefore as a rule of thumb, never go with a brand, in which Casein and Whey are priced at same. As per ground economics, Casein will always be more expensive than Whey.

5. What do I do with the taste and Clumps.

Reports have suggested that the best way to make a Casein shake is to mix it with 1 cup of skimmed milk and the rest can be water. You will find a a better taste and lesser clumps if you just mix a bit of skimmed milk. Secondly, always use a electric blender whenever available. Lastly, add Casein powder after you add Milk/Water as it has a high tendency to stick to the base of the container.


Wish you a great health (Posted on 1/5/12)

Almost any company can produce decent, good-tasting, cheap whey, but doing the same for casein is a trickier proposition. ON has done a solid job with this casein. Mixing it with low-fat or nonfat milk makes for a nice, creamy shake.

A couple of tips: don't bother trying to mix this with a fork or a shaker bottle. You'll get clumps and you'll hate it. Casein demands a blender. (Posted on 1/5/12)
