Egg Protein for Sports & Fitness
How Much Is Usually Taken by Athletes?
It appears that most healthy, active people will experience all of the possible benefits of egg protein by taking 20 grams before or just after a workout.3 The optimal amount of egg protein is not known, but most people use a 30-gram serving providing 20 grams of protein once per day. Athletes sometimes take up to three servings per day, depending on their training level and the protein content of the rest of their diet.
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.
Interactions with Supplements, Foods, & Other Compounds
Egg protein contains a compound called avidin, which interacts with biotin, a B-complex vitamin and prevents its absorption. Avidin is neutralized with heat. Unprocessed egg protein supplements may contain significant amounts of avidin and long-term use could cause a biotin deficiency.
