Supplementing With Egg White Protein

We’ve all heard about the importance of protein intake, especially if you are into sports. Protein supplementation in combination with resistance training has come to become synonymous with strength and muscle gains (Borsheim, Tipton, Wolf, & Wolfe, 2002). Protein and amino acid supplementation can cause increased strength even at rest (Bohe, Low, Wolfe, & Rennie, 2001; Bohe, Low, Wolfe, & Rennie, 2003).

Recommendations for daily protein intake are 1-2g/lb of bodyweight. However, anecdotal evidence points towards young athletes loading up on protein very much in excess of the recommended dosage (Rodriguez, DiMarco, & Langley, 2009).

Commonly used proteins are commercially available whey protein and BCAAs (branched-chain amino acids). However, egg whites, milk, chicken breasts and red meat also serve as great sources of natural protein and have been by ‘strength athletes’ since time immemorial.

How Is Egg Protein Different From Other Proteins?

Egg protein has a biologic value (BV) of 1. What that effectively means is that egg protein is the best protein for human consumption as far as absorption and digestibility are considered. So much so, that the BV of 1 is used as a reference point to compare the effectiveness of other proteins – only whey protein has a better BV value than egg protein. Furthermore, egg protein continues to be one of the cheapest sources of good quality protein.

What’s more, it is packed with nutrients (Harper, 1978) and is a great source of BCAAs – which induce a maximum skeletal muscle anabolic response (Glynn et al., 2010).

Effects of Egg Protein on Muscle Mass

Supplementation with egg white protein may provide numerous training benefits; these are:

• Changes in body composition – increase in fat free mass (FFM) and reduction of fat mass (Hida et al., 2012)

• Prevents muscle breakdown associated with resistance and ensures reduced soreness and earlier recovery

• Increase in 1RM (one repetition max. efforts) (Josse, Tang, Tarnopolsky, & Phillips, 2010; Schmitz, Hofheins, & Lemieux, 2010)

• Increase in muscle strength (as stated above and reflected by increase in 1RM) correlates well with muscle hypertrophy (Hida et al., 2012)

To conclude, although whey protein is considered the gold standard of protein supplementation, egg white protein is still be a very good and cheap source of proteins.
