Protein Blend Supplements
Reviews
The ultimate
muscle-building protein
supplements?
Once the supplement
industry refined the art of purifying
different kinds of protein, it wasn’t long
before supplement companies started
combining the different types into single
protein supplements. They are usually
referred to as protein blends and contain a
combination of several types of proteins for
muscle building. They usually include
whey isolate and concentrate, casein, soy
protein, and egg protein. Protein blends can
be considered the “shot-gun” approach to
protein supplements. Protein blends
are beneficial mostly because of the varying
rates of absorption in the different types
of protein.
For example Whey and Casein can be compared in
a similar way to low and high glycaemic
carbohydrates; meaning they have different
rates of absorption. Whey is comparable to
simple sugar and is absorbed much faster than
Casein. This makes whey a good protein to use
immediately after your work out. Casein can be
considered the complex carbs of protein
supplements in that it is released much
slower. Casein is a great protein for slowly
infusing the muscles with amino acids over a
period of many hours. This makes it a great
protein source for when you are asleep but want
to maximize your muscle building.
Another way to compare the two is by their
effects on anabolism and catabolism. Given
whey’s rapid absorption and utilization it’s a
great protein for increasing protein synthesis
after an intense workout. But it's not as
effective for preventing muscle breakdown or
catabolism as casein. Fighting catabolic
reactions (i.e. muscle breakdown) is best
carried out over longer periods of time; and
slower acting proteins like casein are best for
this.
Another protein found in most blends is egg
protein. Eggs are one of nature’s most perfect
foods and contain all the essential amino
acids. Egg whites are also virtually free of
both fat and carbohydrate. This makes them a
dense source of low-calorie protein for
muscle building. And the latest
refinement techniques insure that the addition
of egg protein to the blend doesn’t interfere
with the product’s digestibility or easy of
mixing.
The fourth protein added to blends is soy
protein. For years soy received a bad rap in
the athletic and bodybuilding community because
of its link to estrogen. But recent research
has shown that while soy has estrogen-like
properties (i.e. lowering cholesterol levels),
it doesn’t increase estrogen hormone levels in
males. As a complete protein with all the
essential amino acids and the ability to reduce
the risk of heart disease and some cancers, soy
protein is a valuable addition to all blends of
protein supplements.
Protein supplement products have come a long
ways over the years. No longer do they taste
like chalk, cause gas and discomfort, and
require a blender for mixing. Protein blends
can be considered the epitome of such products
and should form the nucleus of your muscle
building nutrition.
