Optimum Nutrition 100% Casein Protein
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.
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 tastethis is a great tasting casein protein. My son has a protein shake every night before bed.
Great taste, mixes poorlyOptimum Casein protein tastes awesome, but it does not mix well in a regular shaker. Might need an electric blender to mix well, otherwise it is a bit chunky.
BANANA-Nana-nana-nana!Great Casein protein. I normally take 30 mins prior to bed. Since taking have not woke up craving a midnight snack. Body seems to maintain weight seeing as I am not fasting for 8 hours. DELICIOUS.
Excellent tasteFlavor is excellent tasting.
I feel comfortable after drinking it.
I like it so much-great casein protein!
Great ProductI've always been a fan of Optimum Nutrition's products and I love their casein protein supplement. I drink a shake before bed to help me get those gainz while I sleep.
works wellneed more time to assess all the bad reviews people have given Optimum's casein protein. Since I have been taking it I have not seen or experienced any of the negative comments people have said. It works great for me and it mixes and taste great to me. I don't see what the fuss is about
Good stuffI mix with other powder, more gritty than expected. But good stuff.
Great productAwesome product, slow digesting protein
Take it right before bed. Feeds your body through out the night and wake up feeling recovered/refreshed. Great tasting chocolate protein and easy to mix. Combined this product with a good diet/exercise and watch the fat shed and muscle build...
Awesome mix! Use it everydayOnly 4 stars because the "Chocolate Cake Batter" taste more like coffee. Still good though!
Best caseinIt has a great taste and the results are showing, i've been taking it for two months now, always before bedtime and it help with my sleep.
