Whey Protein for Building Muscle

In the past few years, much research has been done using micronutrients with the purpose of prevention of disease, extension of human life, and increase in athletic performance. It has been known for years that different types of proteins (i.e., whey, egg white, poultry, etc.) have varying effects on human biochemistry and metabolism.

Lately, through extensive research, it has been found that one type of protein has a profound effect on many aspects of human physiology. This protein is none other than whey. Whey protein has many unique properties that make it a great asset to human health and performance, which is especially important to anyone seeking muscle hypertrophy.

Whey has been shown to have a dramatic effect on raising certain hormone levels while also showing an immune boosting effect. One of the aspects of this discovery was the antioxidant Glutathione (comprised of two amino acids, L-cysteine and L-glumatic acid, as well as glycine), which is a powerful antioxidant that has been shown to have a positive impact on protecting the body against free radical damage. Free radicals are waste by-products of human metabolism. These free radicals can cause various problems for humans causing infections, all the way to being linked to causing cancer.

Whey and IGF-1

Insulin like growth factor one (IGF-1) is a growth factor that is released during the breakdown of growth hormone in the liver and is the catalyst responsibile for the growth caused by GH. IGF-1 is directly linked to the quantity and quality of the proteins you ingest.

The quality of protein is measured by biological value (BV) which is the rating given to proteins based on their ability to reach the blood stream in a "good" state; meaning with all the amino acids in tact and able to function properly. Whey protein has a BV of 104 to 159, depending on whether or not it is hydrolyzed, whereas egg white has a BV of 88. This means that a good quality whey protein is almost twice as effective as egg white! Whey also contains the highest percentage of branch chain amino acids (BCAA), L-leucine, L-isoleucine and L-valine. BCAAs are the amino acids used by muscles during intense bouts of exercise. The fact that whey protein is high in BCAAs is of great concern to anyone concerned with (catobolism) muscle-wasting.


The type of processing (i.e., ion-exchange, CFM or hydrolyzing) has a direct impact on the quality and effectiveness of the whey protein you ingest. Look for partially hydrolized whey products such as Designer Whey (Next Nutrition). So I suggest that anyone looking for a good way to add protein to their daily, diet consider whey for its various health and muscle building assets.
