Egg protein is still one of the highest-quality proteins available. It is virtually devoid of carbs and fat, and it is readily digested and absorbed. It is a great pre- and postworkout protein. Egg-white protein is high in sulfur-containing amino acids. These aminos are critical to the body's hormone-producing pathways. It's a good choice for those who are allergic to cow's milk proteins and for those who do not regularly consume eggs. Many egg protein powders now contain avidin-neutralized egg-white powder avidin is a glycoprotein in egg whites that depletes the body of biotin (an essential vitamin that performs critical roles in the metabolism of fats, proteins and carbohydrates, and is important for optimal health).
