Product Overview

Kaged Muscle
Kasein. Micellar Casein Isolate.

After years of research and development, I am proud to share with you the next level in Micellar Casein supplements.

 KAGED MUSCLE KASEIN  is an ultra-premium cold-processed Micellar Casein Isolate that is carefully manufactured from by an innovative micro-filtration process. This filtration method preserves the structural integrity of the protein ensuring that the finished product maintains its natural micellar structure as it is found in milk.

Casein proteins are pH sensitive causing them to thicken in the acidic environment of the stomach. The proteins’ ability to form a gel in the stomach slows down the digestion rate allowing for a sustained release of amino acids. This makes casein ideal for nighttime or prolonged periods throughout the day without protein.

Feed Your Muscles

While You Sleep

 KAGED MUSCLE KASEIN  is a game-changing ANTI-CATABOLIC protein that you can’t live without if you are serious about adding size and strength. During the night your body goes the longest period of time without food. Fasting for 6-8 hours, the body starts going into a catabolic state as it has gone a long duration of time without any nutrients. KASEIN slowly and continuously feeds your muscles a steady supply of muscle-building essential amino acids for several hours.* This plays an important part in maintaining a positive nitrogen balance and long-term anabolic state by preventing muscle protein breakdown.*

The effects of this slow amino acid release have been investigated in a number of studies and have been shown to be very effective at promoting an anti-catabolic environment for muscle growth.*

Not only did my KAGED MUSCLE R&D team build the highest quality Micellar Casein, they took it the NEXT LEVEL by nailing AMAZING milkshake-like flavors for both our NATURALLY flavored and NATURALLY colored vanilla and chocolate options. These flavors are like nothing else you have ever tried! Our R&D team spent over 6 months just working on the flavor systems alone simply because I insisted on its being NATURAL. There’s no reason why you cannot get the results you crave while enjoying the taste of your supplements at the same time.

I am going to reveal some dirty tricks used by many leading supplement companies. This may ruffle some feathers, however, it is my job to make sure you get the facts so you can purchase based on factual knowledge and not marketing hype that over promises and under delivers.

If you are serious with your supplements and training, you owe it to yourself to know these facts before purchasing another casein supplement.

There are many low-cost manufacturing methods for casein protein that many top brands use to cut corners with your results, while increasing their bottom line by using cheaply made ingredients that save them money.

NOT ALL casein is the same.

The type used in the French study was Micellar Casein, which is isolated from milk by filtration, rather than by use of acid or heat. The filtration method I use preserves the structural integrity of the protein, unlike what occurs in other processing methods that many others use.

When heat or acid is used to separate casein out of milk, the micelle’s structures are altered, resulting in a loss of biological activity and digestibility.

How does Micellar Casein differ from Calcium or Sodium Caseinate?

Calcium Caseinate is casein protein which has been separated from skimmed milk with the use of an acid. This means the final protein is not in its natural Micellar structure; the protein is effectively denatured.

After the casein has been precipitated by acid, the mixture is heated again. This causes the protein to further thermolyze and degrade into smaller components, which agglomerate together to form clumps of curd. The curd is then dewatered by high-sheer centrifuging. At this point, the casein has been treated with acid and heat, which literally destroy the integrity of the protein. So, what do you end up paying for? Nothing! You are simply being ripped off. I wont allow that….for me or you.

Raw milk casein is made out of a complex group of protein clusters called micelles, which are bound with calcium, phosphate, and citrate ions and exist at a neutral pH of approximately 6.6, roughly the same as your body’s pH. Native Micellar Casein complements your body’s acid-base balance and will not cause an acidic effect. That’s unlike many top brands’ caseins, which are highly acidifying and need to be chemically alkalized to be edible.

How can you tell which kind of casein you are taking? In the nutrition panel the first ingredient listed should be Micellar Casein. If the brand you are taking is not Micellar Casein, then it’s time for a trade-in.

Questions I Get Asked Frequently

Why didn’t you include a digestive enzyme in KASEIN?
Whey protein, which is FAST in digestion requires a digestive enzyme in order to break it down quickly to be fully utilized, especially post workout….as we do in RE-KAGED. KAGED MUSCLE’s Premium Micellar Casein Isolate, on the other hand, has a VERY SLOW digestion rate which does not require a digestive enzyme to help rapidly digest/break it down into a usable form of amino acids. Instead, Micellar Casein is slowly digested over a 5-7-hour period, supplying a steady supply of muscle-building amino acids.* Several leading brands’ casein proteins use a digestive enzyme to help combat their higher lactose levels due to using a lower-quality protein source. Casein products containing higher amounts of lactose can cause gastric distress to those that are lactose sensitive. You won’t have to worry about this with our KASEIN as it has less than 1g of lactose per serving, making it ideal for those who are sensitive to lactose.

Which protein source is better, Whey or Micellar Casein?
Protein powders, like all supplements, are tools that help you accomplish your fitness goals. Using the RIGHT tools at the RIGHT times makes a BIG difference.

Example: Using a pair of pliers to remove a screw versus using a screwdriver—one is more efficient at getting the job done, however, both will work. Use RE-KAGED post workout or at breakfast and then use the Micellar KASEIN before bed.

Below are a few tips on how I get the best out of both my RE-KAGED and KASEIN protein powders:

*During the day and post workout, use a fast-acting whey protein isolate like KAGED MUSCLE’s RE-KAGED.

*At night or during the day when you will not be eating a protein source for 4+ hours, use a premium slow-release Micellar Casein such as KAGED KASEIN

The reasons: During the day and after exercise your muscles need fast-digesting protein such as whey to counteract the catabolic effect of physical exercise and help with recovery and muscle growth.

However, at night KASEIN is KING and has the anabolic advantage over longer periods of time due its ability to induce a slow and steady release of amino acids to your muscles for several hours, keeping your muscles fed while you sleep.

Take Your Results to the Next Level

If you are currently not feeding your body with sustained release amino acids while you sleep, you are making a BIG mistake! Nighttime is one of the most critical windows to give your muscles a steady supply of amino acids in order to remain nitrogen positive.*

This is the best Kasein product I have ever used, no weird after taste, digested well tasted Incredible didn't set off any allergies. I was very happy with the fact that there were no bloating or digestion issues even when taking a double serving. I have and will continue to recommend this product.

I bought this because while I was cutting, I kept waking up in the middle of the night hungry. I take this before I go to bed and not only does it keep me asleep, it has been easier to retain my muscle mass while loosing weight. I also love the flavor and the consistency of this verse a whey protein. It is much easier on the stomach than whey.

I tried both ON and KM casein , ON leaves me with bloating in the mornings, and it doesn’t mix well , tried the KM vanilla kasein , wow must tell you this is the best ,mixes well and does not gives bloating , have to try chocolate, and yea def recommend this product ,worth your money.

Kaged Muscle Kasein nailed it in regards to an effective Micellar casein. The chocolate milk taste is very good (especially in milk) and it effectively helps hold you over between long periods between meals. No worrying about getting hungry in the middle of night after utilizing the Kasein. The price is $54 for 50 scoops which comes to about $1.20 per scoop. That's about average for a Micellar casein but definitely worth the investment for this one. My only gripe is that there isn't more flavors other than vanilla. Other than that, Kaged Muscle has a more than satisfied consumer with Kasein, I would highly recommend and definitely use again.

I have been searching for a natural / organic casein & whey powder since a while and I have tried many. So far the Kaged products are the best on the market if you are expecting high quality of ingredients and manufacturing ( no GMO, less artificial ingredients etc ). Therefore taste wise, being honest, it's not the best brand. After all you cant have everything. So creative while mixing. Mix with almond/ soy milk, natural fruits, peanut butter, and avoid mix with water.

I am not the kind of guy that write reviews but for this one I do ! Just want to say that this is the sh*t and it's not only the best caseine but also the best protein powder of all the one I've tasted before ! It tastes like real chocolate and not some chemical chocolate alike bullsh*t. Before bed I blend a scoop with peanut butter, a banana and coconut milk and the taste and texture is just awesome ! This really satisfies my gravings before going to bed ! I cannot wait to start bulking again to drink two or maybe three servings. Buy it, try it and you'll love it ! Peace !!!

As with all Kaged Muscle products you get a high quality Casein here. I’ve tried a number of other brands and this is my favorite. No digestive issues. Great for making protein pancakes or mixing with greek yogurt and cinnamon for a night time snack. Also this stuff mixes very easily. No effort. Highly recommend.

One of the worst tasting proteins I have ever had. I’ve never had Kaesin before, so I’m not sure if it’s this product or kaesin. Doesn’t mix well with anything, hard to suck it down.

When I first started using this flavor it tasted delicious. I was sure that I had found my new favorite casein. Then I got through about 2/3 of it and it just started tasting... weird. I'm not sure what happened but now I have to force myself to finish it. Guess I'll have to try something else.

As with all Casein powders I have tried, it mixes best with just water. This one does mix better than others I've tried and it tastes better to. I recommend this product.

What happened to this protein? This was the BEST casein protein by a mile in terms of taste, now it is absolutely disgusting. At first it tastes fine, but then comes this horrid chemical after taste. I honestly thought my batch of protein was expired by how bad it tastes compared to how it used to. Oh well, time to find another go to casein protein.

Hands down the best tasting casein I've had thus far. Tried all of the major brands, and while they're all good, I think this is better. And if you buy the hype, it's a better product as well. Only minor complaint is its a lot "fluffier" than other caseins and it seems to get everywhere no matter what. Otherwise, I'm a fan and this will be my go to product from now on!
