Egg whites are a high-protein, low-calorie food. Egg protein powders, especially those derived from pure egg whites, can offer as much as 4 times the amount of protein found in one whole egg, in just one scoop of powder. As egg protein powder contains no dairy products, it's a great protein source for those who suffer from lactose intolerance.
According to the Egg Nutrition Center (ENC), the average egg contains about 6.29 grams of protein, 3.6 of which come from the egg white. In addition to proteins, other nutrients found in the egg white are riboflavin, niacin, folate, vitamin B12, calcium, iron, copper, zinc and sodium.
Egg white protein is a highly pure and complete source of protein that’s great as a part of a supplementation program for athletic performance or weight loss, especially if you follow a paleo, ketogenic, or low-carb diet.
Egg white protein is low in carbs, very high in protein, and since it’s derived from only the egg white and not the yoke, it is also free of fat and cholesterol.
Unlike dairy-derived proteins like whey and casein, it isn’t heavily processed.
