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.

Casein good stuffUsed it every night before bed while I was working out hard. Seemed to work very well. I believe it helped me greatly build several pounds of muscle.
Better than mostTerrific service and prices!
Casein is okayI use it before I go to bed the slow release formula allows my body to use the amino acids while I sleep and recover
Great price for a slow digesting protienI used the product two to three times a day away in between meals. Mix any amount with Whey and get the benefit of both protein powders at the same time. Used at least one hour away from before or after workout.
Great Product!This is great stuff! I drink a shake before bed of this stuff and recovery time is basically nothing!
The best bang for your buck!I use this as my before bed protein because of it's slow release rate. Optimum protein mixes are the best value for your dollar. Works as good or better than any protein mix I've tried at any price! Mixes readily in a shaker but may need a little more milk/liquid then recommended as consistency can be thick when mixed as directed. It has a great selection of flavors with great taste too!
