Product Description

Flavor: Chocolate Supreme | Size: 4 Pound

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.

5.0 out of 5 stars Great Product, worth the price January 6, 2013
By Grant J
Flavor Name:Chocolate Supreme|Size Name:4 Pound
I take casein before bed and it significantly reduces my muscle aches after my routine and into the next day. Everything I've read about casein protein said it is best used before bed due to it's slower digestion rate, which is exactly what I've been doing. I've tried the various flavors and none of them are impressive taste-wise, but they definitely do the job of repairing muscle tissue while i sleep. I base this on how sore my muscles feel the next day.

If anything, the intensity of my workouts have increased as of late but what used to feel like total muscles soreness and fatigue has turned more into a solid tightness that goes away faster than before.

The price on this is somewhat high if you compare it to some of the regular whey proteins out there. I still take whey daily, post workout usually, but taking into account that this protein contains 24g of quality casein protein per scoop along with 5g of BCAA and 5g of glutamine, we're talking about those extra dollars be spent wisely.

I have also been adding beta alanine and Citrulline Malate post-workout. These two are also meant to speed recovery and increase muscle endurance -Primaforce Beta Alanine Powder 200 Grams + FREE Citrulline Malate 250 Grams. Pretty wicked combo. I've been taking these supps for the past six weeks in addition to the casein and really think its the best post workout recovery aid I've had in my years of lifting.

5.0 out of 5 stars What makes ON- Casein Special ? September 12, 2011
By Sam
Flavor Name:Chocolate Supreme|Size Name:4 Pound
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 to only someone who is at intermediate or advance fitness levels (rest will do good with cottage cheese- provided you relish it). If you are a beginner, than please stay away from pure Casein supplement for a while, 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

Flavor Name:Chocolate Supreme|Size Name:2 Pound
This is the most cost efficient and quality ratio of Casein you can probably find. With 2 day shipping with Amazon Prime and getting this every month automatically is a deal thats out of this world. I have tried several flavors, some better than others but thats not what matters. Just go with the cheapest, the chocolate for 2lb or cookies and cream for the 4lbs. Regardless of the taste, which isn't bad by the way, taking this protien before you go to bed is the best thing you can do, but you are not doing, towards building a better body.

You can really feel the filling effects of this stuff as you lay there and knowing your muscles have adequate nutrition to get them through the night is peace of mind. I can honestly say since taking this, i have slept better and i have made more gains than ever before. Its not a miricle pill or rocket science, its plain good ole nutrition for your body, when you need it the most.

Combine Casein and Whey during different times of the day for optimal effects.

What i have found what works best for me is the following.

Morning: Shake of 25 percent Casein, 75 percent Whey.

Before workout: Shake of 100 percent Whey.

After workout: Shake of 75 percent Whey, 25 percent Casein.

Before bed: Shake of 100 percent Casein.

I found this works best for me after a lot of tweeking, but for others depending on protien needs, it may vary.

Buy some today and enjoy.

I own a horse.
