Description
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 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.

Directions
Use ON 100% Casein Protein first
thing in the morning, immediately before bed, in place
of small meals, and/or any other time when delayed
protein absorption is desired. To encourage a positive
nitrogen balance, consume approximately 1 gram of
protein per pound of body weight per day from a
combination of high protein foods and supplements. For
even better results, consume your daily protein
allotment over several small meals spread evenly
throughout the
day.
