Despite popular belief, proteins are exclusively beneficial to muscle
cells. In fact every cell of the human body contains different forms of
proteins. Bodybuilders usually associate protein with muscle repair and
regeneration. Professional body builders tend to use protein powder as a
complementary means of providing the body with building blocks for the
muscle cells. This type of protein is usually obtained with the help of
industrial processes from milk, eggs or soy. Milk is the most common
source of protein. The whey protein is extracted from the liquid
byproduct obtained from cheese. Through proper filtering and
dehydration, the whey protein is transformed into concentrated protein
powder. A false misconception is the idea that protein helps the muscle
mass to grow. Muscle mass growth is achieved through physical exercise.

However, this is not the only role of protein in the human body.
Proteins are also responsible for DNA replication, repair and
transcription. Some of them are also responsible for structural
functions, capable of generating mechanical forces while others serve as
key elements of the antibody system. In fact, insulin and enzymes are
proteins as well.

Simply put, proteins represent essential parts of every living organism
and participate is literally every process that takes place within a
cell. The discovery of this key ingredient determined the protein
manufacturing known today. By increasing the quantity of proteins the
body absorbs, cellular health can be improved. Ideally, food should be
the main source of proteins, especially for bodybuilders. Unfortunately,
the quality of commercialized foods is debatable and most of the time,
the proteins provided by regular meals are not enough to keep the human
body working at optimal levels.
