Egg Protein

 

Eggs are an excellent source of high-quality protein.

Of all whole foods, eggs have the highest protein digestibility-corrected amino acid score (PDCAAS).

This score is a measure of a protein’s quality and digestibility (28Trusted Source).

Eggs are also one of the best foods for decreasing appetite and helping you stay full for longer (29Trusted Source, 30Trusted Source).

However, egg protein powders are typically made from egg whites rather than whole eggs. Although the protein quality remains excellent, you may experience less fullness because the high-fat yolks have been removed.

Like all animal products, eggs are a complete protein source. That means they provide all nine essential amino acids that your body can’t make itself.

What’s more, egg protein is second only to whey as the highest source of leucine, the BCAA that plays the largest role in muscle health (31).

Keep in mind that egg-white protein hasn’t been studied as much as whey or casein.

In one study, it demonstrated less potential to reduce appetite than casein or pea protein when consumed before a meal (32Trusted Source).

In another, female athletes taking egg-white protein experienced similar gains in lean mass and muscle strength as those supplementing with carbs (33Trusted Source).

Egg-white protein could be a good choice for people with dairy allergies who prefer a supplement based on animal protein.

Summary Egg-white protein is high in quality and easily digested — though it may not keep you feeling as full as other protein powders.
