How Much Protein Is in an Egg: Size, White & Yolk

A large egg contains 6.3 grams of protein. That’s split between the white and the yolk, and the exact amount shifts depending on egg size, ranging from about 4.8 grams in a small egg up to nearly 8 grams in a jumbo.

Protein by Egg Size

Most nutrition labels and recipes assume a large egg, but the protein content scales predictably with size:

  • Small (38 g): 4.79 grams of protein
  • Medium (44 g): 5.54 grams of protein
  • Large (50 g): 6.3 grams of protein
  • Extra large (56 g): 7.06 grams of protein
  • Jumbo (63 g): 7.94 grams of protein

If you’re eating two large eggs at breakfast, you’re getting about 12.6 grams of protein. A three-egg omelet puts you around 19 grams, which is a meaningful chunk of most people’s daily needs.

White vs. Yolk

The egg white holds more than half the protein. A single large egg white provides about 3.6 grams of protein for just 17 calories, which is why egg whites are popular with people watching their calorie intake. The yolk contains the remaining 2.7 grams of protein along with most of the egg’s fat, vitamins, and minerals, bringing the whole egg to 71 calories total.

If you’re choosing between whole eggs and whites purely for protein efficiency, whites win on a per-calorie basis. But the yolk carries nutrients you’d miss out on, including vitamin D, choline, and iron. For most people, whole eggs are the better choice unless you’re specifically trying to cut calories while keeping protein high.

Egg Protein Quality

Not all protein is created equal. Your body absorbs and uses protein from different foods at different rates, and eggs consistently rank at the top. Egg protein is considered a gold standard for quality because it contains all nine essential amino acids in proportions your body can use efficiently. When researchers compare common protein sources like milk, beef, and soy, eggs score highest for biological value, meaning the percentage of protein your body actually puts to work.

Cooking Matters for Absorption

How you prepare your eggs affects how much protein your body actually absorbs. Protein digestion from raw eggs is around 40% lower than from cooked eggs. Cooking unfolds the tightly wound protein structures, making them far easier for your digestive enzymes to break down. So if you’ve been adding raw eggs to smoothies thinking you’re getting the full 6.3 grams per egg, your body is likely using closer to 3.5 to 4 grams. Scrambled, boiled, poached, or fried all deliver the full benefit.

How Eggs Compare to Other Protein Sources

Eggs are convenient and affordable, but they’re not the most protein-dense food out there. Here’s how a large egg stacks up against other common options:

  • Chicken breast (3.5 oz): 22.5 grams
  • Salmon (3.5 oz): 20.3 grams
  • Edamame (1 cup): 18.4 grams
  • Lentils (1 cup, cooked): 17.9 grams
  • Greek yogurt (5.5 oz): 16.1 grams
  • Almonds (2 oz): 7.6 grams
  • Peanut butter (2 tbsp): 7.1 grams
  • One large egg: 6.3 grams

The real advantage of eggs isn’t that they pack the most protein per serving. It’s that they’re fast to prepare, inexpensive, and extremely versatile. Two eggs scrambled in the morning take three minutes and deliver roughly the same protein as a container of Greek yogurt. Paired with toast or beans, that’s a solid meal.

Practical Protein Math

Most adults need somewhere between 50 and 100 grams of protein per day, depending on body weight and activity level. A rough guideline is 0.36 grams per pound of body weight for sedentary adults, and up to 0.7 grams per pound for people who strength train regularly. At 6.3 grams each, eggs alone won’t carry your entire daily intake, but they’re an easy building block. Three eggs at breakfast covers roughly 19 grams, leaving you well positioned to hit your target across the rest of the day with normal meals.
