Slow Protein Digestion, Anti Catabolic Micellar Protein With Glutamine!

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. Casein protein is the most abundant protein present in milk. It is considered a high quality protein because it is easily assimilated and it supplies sufficient quantities of amino acids that cannot be synthesized by the body.

Another benefit is increased satiety (feeling of fullness or satisfaction). Casein exerts a slight pressure on the stomach walls. In effect, this pressure signals to the brain to stop eating because the stomach is full. Casein is the most slowly digested and absorbed type of protein. This helps create a "timed-release" effect, providing a steady stream of amino acids to your muscles over a long period of time. The net result is a greatly enhanced anti-catabolic environment which is much more friendly to growth and recovery.

Bodybuilders and athletes looking to build lean muscle, prevent muscle breakdown, and reduce recovery times, and individuals interested in improving the quality of their sleep can greatly benefit from casein.

Casein Research

Perhaps the most interesting kernel on casein to come from the scientific community is the Boirie study, which found that casein managed about a 31% increase in protein synthesis (to whey's 68%)... but also reduced whole-body protein degradation (catabolism) by 34%. More importantly, researchers found that casein contributed to a positive nitrogen balance an average of 7 hours after ingestion.

The Biorie study has since spurred further research of casein. Another study looked at the effect casein might have on body composition when used as part of a 12-week weight-training program. Participants were separated into two groups, each of which maintained a balanced diet including 75 grams of protein per day. The difference was in the sources of protein used: while the first group relied on whey-based drinks to reach their daily protein requirements, the second group made use of milk protein isolates (80% casein, 20% whey). At the end of the study, the milk protein isolate group had lost more fat (15.4 lbs. vs. 9.2 lbs.), gained more lean mass (9 lbs. vs. 4.4 lbs.), and gained more upper and lower body strength than the whey group.

Additional studies, though not as influential, have indicated casein may lower "bad" LDL cholesterol levels and increase "good" HDL cholesterol levels at the same time. In people whose immune systems were weakened by illness or disease, casein appears to demonstrate anti-viral and immune system-enhancing properties. Casein has even been linked to decreases in inflammatory factors in cardiovascular disease.

    Good Stuff
    This is a good product. I used it before bed and sometimes after lunch to help fill in some of my nutrition gaps. I works really good. I don't have the hunger crashes that I used to have and when I wake up in the mornings I am not all weak and foggy. This product works but man they have to make it taste better. Raspberry flavor and at first I was like no way but I found that if you mix it with co

    Banana Cream tastes bad!
    I recently started working out again and I bought a bunch of products including this one. I specifically used this protein as a meal replacement since I work a full time job. I bought Banana Cream and to be honest it tastes pretty bad. It mixes well in my blender bottle. The bottle does say to put one scoop of the powder and mix with water but I was using two scoops and the consistency was ver

    I use this product with my morning meal and for a late night snack. Delicious flavors. I like to mix it and then refrigerate after. Akin to a pudding texture when chilled. WAYYYYYYYYYY healthier than any pudding I've ever tried.

    Better Options Available
    I got this product due to a friend's recommendation. I work out at least five days a week and take it as a meal replacement during the day or before bed for supplemental protein.||The taste is OK at best. I've tried the double chocolate and the banana cream. Maybe it's the nature of the casein powder but every time I mix it in a shaker cup it mixes horribly. It's consistently lumpy and chalk

    Casein product that tastes great!
    This is a great tasting product (I'm loving the banana cream flavor). I've seen other reviews elsewhere where people complain about how it doesn't mix well or has a bad texture. The more liquid you add the thinner it is it does mix up thicker than other shakes but it mixes well with a spoon or a mixer.
