Muscle Milk Protein Supplement
I'm just finishing up my current tub of Cytosport's Muscle
Milk protein powder, and I'm very impressed. This is my
first time trying Muscle Milk, by the way. I've always heard
a lot of good things said about Muscle Milk (taste and quality
wise), and at the first chance, I picked up a tub of banana
There are many whey protein powder supplements on the market,
and most are quite "similar" - and users buy them
depending on their own preferences of taste, price, brand
name, etc... At the same time, there are different types
of protein powders aimed for different needs and purposes.
For example, pure whey protein for post workout, and protein
blends for other times during the day, or a bed time protein
shake. Then there are different quality protein powders
mainly whey concentrate, whey isolate, or a mix of both.
Whey concentrate powders are quit a bit cheaper than pure whey isolate powders
Cytosport Muscle Milk fall in the category of protein blends,
most fit for use throughout the day, and also as a bed time
protein. Muscle Milk is a protein blend of whey
and casein proteins - in what Cytosport calls their EVOPRO
formula - "evolution based protein".
Muscle Milk - Evopro - What is it?
As mentioned above, Muscle Milk is an ideal bed time protein
because of its protein blend of whey and casein, and not
necessarily ideal to take post workout. This "EvoPro"
blend, is what Cytosport dubs as "Nature's Ultimate
Anabolic Protein - Amino Blend". Why is that? Besides
the whey and caseins in this blend, Muscle Milk is patterned
after human mother's milk, which has important anabolic
Muscle Milk includes alpha and beta micellar caseins, Alpha-Lactalbumin,
Purified Bovine Colostrum Extract (rich in Secrotory IgA
and IGF-1), lactoferrin, glutamine peptides and more. So
just what are some of these ingredients?
Alpha-lactalbumin has a protein efficiency
ratio of 4.0 compared to 3.6 for whey and 2.9 for casein
protein. Alpha lactalbumin also has higher biological value
than both whey and casein proteins. It contains large amounts
of essential and conditionally essential amino acids.
Bovine colostrum - Colostrum is produced
by female mammals during first 24 to 48 hours after birth,
and it contains immune factors along with antioxidants,
vitamins, minerals, enzymes, amino acids, and other growth
factors. Bovine colostrum is identical to that found in
human colostrum but at higher levels. In short bovine colostrum
plays an important role in immunity to diseases among other
There are various claims that bovine colostrum boosts IGF-1,
however, after doing some research on this at pubmed, it
does not appears so. While I found that many studies found
bovine colostrum to provide significant benefits for athletes,
but it did not boost IGF-1 like what many claim. Below are
just a few of the many studies available.
If you're lazy to read (and try to understand these studies),
the gist of it, is that bovine colostrum provides many benefits
for athletes, but non of the studies I viewed could confirm
that it boosted IGF-1.
Anyways, let's chat a bit on the protein blend of Muscle
Milk, which is made up of whey and casein (Micellar Alpha
and Beta Caseins and Caseinates, Whey Concentrates, Whey
Isolates, Whey Peptides). If you've read my Met-rx
meal replacement review, you may find some similarities
in this protein blend. (where Met-rx calls their blend the
The main reason why the whey & casein blend is so popular
(effective) as a night time protein is because of their
different rates of digestion and absorption.
Whey protein is digested and absorbed
rapidly, which also fills your blood with more amino acids
rapidly, but this effect doesn't last long. So Whey protein
is quick in, quick out. Increase in amino acid blood levels
inhibits muscle breakdown and stimulates protein synthesis.
However, research has shown that whey protein is oxidized
(burned up) as much as it is used for protein synthesis,
which means that less of what amount of whey you take in
is used to build muscle.
This is where casein protein comes in.
Casein proteins have slower rate of digestion and absorption,
this then gives it more time to fuel protein synthesis,
and less into energy production. So in a nut shell, whey
protein provides aminos almost immediately, and once the
whey is all "used" up, the casein kicks in and
continues to provide your system with amino acids - like
a time release formula.

If you look at the fat content of Muscle Milk, it's quite
high - probably higher than any other protein supplement
out there. But there's no need for alarm, since this was
intended in the formulation of Muscle Milk. Most of the
fat are medium chain tryglicerides (MCT) - they have slightly
lower calorie content, and are more rapidly absorbed and
burned as energy. MCT is also shown to increase calorie
burning compared to other fats.
Cytosport Muscle Milk Taste
Muscle Milk comes in a variety of flavors: chocolate, vanilla,
strawberry, mocha joe, root beer, and banana cream. I've
tried banana cream and strawberry.
First of all, Muscle milk is pleasant to smell. ;-) The
banana cream smells just like fresh bananas, and the taste
is fantastic, even with just water. But I would recommend
using milk, or if you're lactose intolerant like me, use
soy milk. I give it a 9.8/10 on taste.
The strawberry flavor was very good as well. I'm usually
not big on strawberry flavors, but I got a single packet
sample, and I have to say that this was probably the best
strawberry flavor I've tasted compared to any others. Overall,
Muscle Milk is just a fantastic tasting protein supplement.
Muscle Milk costs $40 retail for a 2.48lb tub, but shop online, you can buy Muscle Milk for much cheaper for under $30.
