Met Rx is a protein mix that's been around for
quite awhile, and many athletes use Met Rx to supplement their workouts.
Met Rx provides a good amount of proteins with low levels of fat
and calories. It uses Met Rx's proprietary protein blend called
the Metamyosyn Blend, which is a mix of milk protein, casein protein,
and whey protein.
This Proprietary blend by Met Rx is supposed to
be the optimal blend of proteins that promotes muscle growth and
enhances recovery. So is this really the case? Read on and learn
more about Met Rx meal replacement.
Met Rx Taste Test
Taste wise, Met Rx isn't the best, nor is it the
worst - just some where in the middle. On the plus side, it doesn't
have any added sugars or artificial sweeteners - so, no fillers
to make it taste better. Which really, in my opinion, is a good
thing, because then you know you're getting mostly good stuff. ;-)
I'm not fussy about taste, so I prefer protein
mixes that focus on content instead of appearance, which is also
why Isopure Meal Replacement
is on the top of my list.
I prefer just the original vanilla flavor. As
I said, it doesn't contain artificial sweeteners, so this won't
be as tasty as some other meal replacements, but I like to mix this
with chocolate milk, and it tastes quite good.

Compared to most other meal replacement powders,
Met Rx has relatively few calories and a comparable amount of proteins.
A serving contains 250 calories, 22 carbs, and 37g proteins. One
of the major benefits of Met Rx is the overall nutritional value
it provides. Take a look - it contains sodium, potassium, and even
Met Rx Proprietary Metamyosyn Blend
Now, let's get to the interesting part - Metrx
Proprietary Metamyosyn Blend. What the heck is this Metamyosyn blend???
It's actually not that complicated - it just sounds pretty good.
;-) Met Rx Metamyosyn blend is a mix of milk, casein, and whey proteins,
with some glutamine thrown in.
So just how good is this Met Rx blend? Metamyosyn
was originally developed by Dr. Connelly, who performed extensive
post-medical surgical research. In short, how well patients survived
after surgery. He found that RNA synthesis and protein transfer
in myosin filament chains achieved greatest sensitivity to nutritional
intervention - meaning that results were most noticeable, hence
the name Metamyosyn, and Met Rx is a 'treatment' for specific metabolic
requirements emphasizing intervention on the myosin filaments.
Why does this Metamyosyn blend work? Let's look
at the 2 main components: whey protein and casein protein. 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. It make
the Metamyosyn formula work more efficiently because 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 now, you can see how Met Rx combining whey and casein makes a
good combo for energy production and protein synthesis.
At retail, a box of Met Rx will cost you around
$50. Shop online and you can save yourself over $15 bucks.
