How much protein is in egg whites?

Egg whites are about as close to pure protein as whole food gets. Strip away the yolk and what’s left is roughly 10.9 g of protein per 100 g with almost nothing else: about 0.2 g of fat, under a gram of carbohydrate, and only 52 calories. The white of one large egg carries roughly 3.6 g of protein; the 3-tablespoon scoop most people pour from a carton (46 g) runs a little larger, around 5 g. That ratio — real, complete protein with the fat and calories stripped out — is the entire reason egg whites exist as their own category.

Lean, complete, and very low calorie

The headline isn’t the protein count; chicken breast and Greek yogurt both beat whites gram for gram. It’s how clean those grams are. Egg white protein is a complete protein, carrying all nine essential amino acids in a form your body uses efficiently, and it arrives with essentially no fat, no saturated fat, and no cholesterol. At about 24 calories for a 3-tablespoon serving, the protein-to-calorie ratio is hard to beat among everyday foods.

That’s why whites are the classic cut-fat-keep-protein move. When someone is managing calories or watching dietary cholesterol but doesn’t want to sacrifice protein, the white is the lever they pull. You can fold a big pour of whites into a scramble, bulk up an omelet, or whisk them into oats and add a meaningful slug of protein for almost no calorie cost — something you can’t do with whole eggs, where the yolks add up fast.

White vs. whole egg: what you trade

Here’s the part worth being clear about, because it’s where the real decision lives. A whole large egg has about 6.3 g of protein; the white alone has about 3.6 g. So the white isn’t a watered-down egg — it’s specifically the protein-and-water half. The yolk holds the rest: the remaining ~2.7 g of protein, and all of the egg’s fat, its cholesterol, its choline, and its fat-soluble vitamins (A, D, E, and K).

That makes the choice a genuine trade rather than an upgrade. Go with whites and you keep most of the protein while shedding the fat and calories — but you also give up the yolk’s nutrients, which are some of the best parts of a whole egg. For most people most of the time, eating the whole egg is the better all-round choice. Whites come into their own when the goal is narrow and deliberate: stack lean protein, hold calories down, and lean on another food (or the occasional whole egg) for the nutrients the yolk would have provided.

Cartons, convenience, and hitting a number

Separating yolks by hand is tedious and wasteful, which is the practical case for cartoned liquid egg whites. They’re pasteurized, they pour straight into a pan or shaker, and — most useful if you’re tracking — they’re easy to measure by the gram or tablespoon. The trade-off is that some cartons add a little sodium for stability, so it’s worth a glance at the label if you’re keeping sodium low; plain whites are otherwise just whites.

To put the density in target terms: hitting 30 g of protein from whites alone takes about 275 g — a bit over a cup of liquid whites, or the whites of roughly eight large eggs. That’s a lot of cracking and separating to do by hand, which is exactly why people who build meals around whites buy the carton. As a standalone, whites usually work best as a booster rather than the whole meal — a large pour alongside whole eggs, oats, or another protein clears the gap comfortably.

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