Egg Protein

Possible Deficiencies

While protein deficiency is a problem in many parts of the world, it is uncommon in the developed world, since protein-rich foods like meat, fish, dairy, eggs, and legumes are generally abundantly available. There is no such thing as an egg protein deficiency.

Side Effects

Eggs cause allergic reactions in some people. The symptoms of an egg allergy range from digestive upset or a mild skin rash to a life-threatening constriction of the airways. People with egg allergies should avoid all forms of egg protein.

Because raw egg protein can cause biotin deficiency, people taking egg protein supplements long term should consider supplementing with biotin. Symptoms of biotin deficiency can include skin, hair, and nail changes; loss of muscle function; and seizures.
