How much protein is in egg?

One large egg carries about 6.3 g of protein in a 50-gram package — roughly 12.6 g per 100 g — and it is some of the highest-quality protein on your plate. What makes the egg unusual isn’t the quantity; chicken breast and Greek yogurt both beat it gram for gram. It’s the quality and the way that protein is split between two very different halves.

The egg is the reference protein

Nutrition scientists need a yardstick to measure how usable a protein is, and for decades the whole egg has been that yardstick. It contains all nine essential amino acids in almost exactly the ratio the human body wants, which is why it scores at or near the top of the two scales that matter — PDCAAS and the newer DIAAS. In plain terms: your body can put nearly every gram of egg protein to work, with very little wasted. Among foods people actually eat every day — not isolated powders — the egg is about as good as complete protein gets. That’s the real reason a 6.3 g egg punches above its weight: those grams are the gold standard, not filler.

White vs. yolk: where the protein actually lives

Here’s the part most people get wrong. The protein in an egg is not concentrated in the yolk — it’s split, and the white holds the larger share. A large egg’s white contributes roughly 3.6 g and is almost pure protein, with essentially no fat and very few calories. The yolk adds about 2.7 g, but it carries far more than protein: nearly all of the egg’s choline, its fat-soluble vitamins (A, D, E and K), and all of the fat sit in that yolk.

So the white-only or “egg-white” approach isn’t crazy — it’s a deliberate trade. You keep most of the protein and shed the fat, the calories, and the cholesterol, which is why cartoned liquid whites are a staple for anyone cutting calories while protecting their protein. But you also give up the yolk’s choline and vitamins. For most people, eating the whole egg is the better all-round choice; reach for whites alone when you’re specifically trying to stack protein without the extra fat and calories.

One thing that doesn’t move the needle: cooking. Scrambled, boiled, fried or poached, a large egg still lands around 6.3 g. Heat denatures the protein, which actually makes it easier to digest than raw egg, but it doesn’t add or destroy meaningful grams.

Using eggs to hit a protein target

Because each egg is a tidy ~6.3 g, the math is easy to do in your head. Two eggs put you near 12.6 g; a three-egg scramble clears roughly 18.9 g before you’ve added anything. That’s a solid anchor for a meal, though on its own it usually isn’t a full serving — most people aiming for 25–30 g per meal pair eggs with another protein: a couple of eggs alongside Greek yogurt, cottage cheese, or a few slices of turkey gets you there comfortably. Whisk in a splash of milk or fold in cheese and the number climbs further.

How many you actually need depends on your bodyweight and goals, not on the egg. If you’re trying to work out a daily number to build your meals around, see our guide on how much protein per day — then use eggs as one of the cleanest, most complete ways to chip away at it.
