The industrial process behind this essential nutritional supplement is
actually quite simple. The main raw ingredient for protein extraction is
milk. The most popular form of this protein is whey. This particular
protein is absorbed faster, reaching the muscle cells in a matter of
minutes instead of hours as with a normal meal.

The first step of the process requires the milk to be pasteurized. By
heating the milk, harmful bacteria get neutralized. Once pasteurized,
the protein will be separated from the milk. Once the curds are removed
to make chees, the remaining liquid also called as the whey portion gets
filtered. The filters separate the protein from the other ingredients.
The third step is called purification. During this process, electrically
charged particles interact with the protein cells. The direct result is
a concentration of the whey protein, braking down the molecules into
smaller and easier to absorb chains.

The fourth and final step requires the protein to be dried. In a drying
tower, the water within the whey protein gets removed, turning the
substance into a powder.

Even if milk is the most popular source of protein for nutritional
supplements, other substances can be used as raw ingredients as well.
Protein can also be extracted from soy and eggs. Because the process
involves almost no chemical treatment, the whey protein is probably the
most pure nutritional supplement available to the general market. It is
also the most efficient supplement for body builder. It’s absorption
rate is far superior compared to other forms of protein. For optimal
results, whey protein should be used not later than 45 minutes after the
regular gym workouts. This way, they will help the muscle cells rebuild
and gain mass.
