A typical 1 large egg serving of omelet contains 6.5 grams of protein (10.6 g per 100 g), which makes it a moderate source of protein. That covers roughly 13% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Around 28% of the calories in omelet come from protein, so it is moderately protein-dense. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
Among the 20 eggs in the database, omelet ranks 9th by protein per serving, and 408th out of all 796 foods on the site. Set against fried egg, another egg entry in the database, a serving carries about 0.2 g more protein (fried egg has 6.3 g per 1 large).
It is a complete protein - it supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own. The serving above is counted by piece at 61 g. Because pieces vary, the per-100 g figure is the one to use when comparing this against a food measured a different way.
