Eggs are one of the most popular and affordable sources of high-quality protein. Whether you’re trying to build muscle, lose weight, or simply eat healthier, you’ve probably wondered how much protein in an egg and whether the yolk contributes to that total.
The short answer? A single large egg contains about 6–7 grams of protein, but there’s more to the story. In this guide, we’ll break down how much protein in an egg yolk, egg whites, different egg sizes, and why eggs are considered a nutritional powerhouse.
How Much Protein in an Egg? Quick Answer
A large whole egg (about 50 grams) contains approximately:
- Protein: 6.3 grams
- Calories: 70–78
- Fat: 5 grams
- Carbohydrates: Less than 1 gram
Here’s a quick breakdown by egg size:
| Egg Size | Protein Content |
| Small egg | 4.8 grams |
| Medium egg | 5.5 grams |
| Large egg | 6.3 grams |
| Extra-large egg | 7 grams |
| Jumbo egg | 7.9 grams |
So if you’re tracking macros, knowing the egg size can slightly change your protein intake.
How Much Protein in an Egg Yolk?
Many people assume all the protein is in the egg white, but the egg yolk also contains protein.
- Egg yolk protein: About 2.7 grams
- Egg white protein: About 3.6 grams
That means nearly 40% of the protein in an egg comes from the yolk.
Besides protein, the yolk is packed with nutrients like:
- Vitamin D
- Vitamin B12
- Choline
- Healthy fats
- Antioxidants (lutein and zeaxanthin)
So skipping the yolk means missing out on valuable nutrition.
Egg White vs. Whole Egg: Which Has More Protein?
Here’s a quick comparison:
Egg White
- 3.6 grams protein
- Almost no fat
- Very low calories
- Pure protein source
Whole Egg
- 6.3 grams protein
- Healthy fats
- More vitamins and minerals
- More filling
If you’re focused purely on protein with fewer calories, egg whites work well. But for overall nutrition, whole eggs are the better choice.
