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.

    Great Product
    I've been using this product for a couple of weeks now and have been impressed with the results. I take it at night as recommended
  2. Quality
    Excellent Evening Protein Drink
    Use 100% Casin Protein for evening drink either right before bed or one hour before. Great for killing the night time hunger. Use one to two scoops depending on how I feel. Great quality for the amount spent.
  3. Quality
    Worth the extra money spent.
    Tastes very good. I drinking in the morning right before I get to work. It satisfies my morning hunger and gives me enough energy to get through my sometimes physically demanding day in construction.

    Don't understand all the good reviews...
    This stuff is a pain to mix properly. Even with a blender it doesn't fully blend. One scoop protein with 20oz milk and it's still very thick. Tastes like protein did 10 years ago. When I wake up after taking it the night before I feel bloated and gassy. I don't understand all the great reviews. Maybe I received a bad batch...
  5. Quality
    good stuff
    It tastes great but if you take too much it will give you diarrhea until you lessen the dosage or get used to it.
  6. Quality
    Poor Tasting
    I did not use the product to the extent where I could compare if it was beneficial to me.
  7. Quality
    I use this right after a work out and whenever I need a late night snack and want to avoid the carbs at all costs. On the plus side these shakes end up pretty thick so it helps to stave off the hunger. On the minus side these shakes end up pretty think so it's kind of hard to get it all mixed in.

    Good Stuff
    Vanilla and Banana Creme are both pretty good tasting. If you're thinking Muscle Milk banana creme then you're going to be a little disappointed; its still a good flavor however. If you mix a shake and then leave it in the fridge for 20 minutes or so it seems to absorb the milk which greatly reduces the chalky consistency that it tends to have if drank right away. A good product and definitely bes

    Best tasting...I'm seeing improvement.
    the banana cream tastes like the banana shake from sonics but without all the nasty calories and fat. just mix with water..tastes great!

    Great overnight protein shake!!!
    As you might or might not know Casein is the main protein in milk the other one being Whey. Unlink Whey Casein digests slowly which means it takes longer for it to get broken down and absorbed but it will last longer in the organism. This just means that if you take it overnight you will have a steady flow of amino acids being absorbed by your body during those 7 or 8 hours of starvation (y
