How Much Protein Is in 3 Eggs?
Three large eggs provide roughly 18g to 19g of protein in total, for around 210 to 230 calories, making eggs one of the most reliable and affordable protein sources available. Here is where that protein comes from within the egg, and how egg size and preparation change the figure.
The breakdown by egg size
A large egg of about 50g of edible content carries roughly 6g to 6.5g of protein, so three come to about 18g to 19g in total. Medium eggs sit nearer 5.5g of protein each, while extra-large eggs are closer to 7g each, so the exact total depends noticeably on which size you buy.
This means the difference between three medium eggs and three extra-large eggs can be as much as 4g to 5g of protein, which is worth knowing if you're tracking intake closely rather than assuming all eggs are equivalent.
How whites and yolks split the protein
Roughly 60% of an egg's protein sits in the white and 40% in the yolk. Because the yolk holds nearly all the fat and most of the calories, egg whites alone are far more protein-dense: three whites give about 10g of protein for under 60 calories, compared with around 18g to 19g and 210 to 230 calories for three whole eggs.
The yolk isn't just fat, though — it carries most of the egg's vitamins, including vitamin D and B12, along with choline, so removing it entirely trades some nutritional breadth for a leaner protein hit.
Making three eggs into a 30g breakfast
Add three extra whites, 30g of grated cheese, or a 100g serving of cottage cheese folded into the scramble at the end of cooking. Any of these takes the plate past 30g of protein without much extra cooking effort or a significant change to the dish.
Cooking method itself does not change the protein content of eggs — scrambled, poached, fried or boiled all provide the same protein per egg. Cooking does make egg protein safer and more digestible, since heat denatures certain proteins in raw egg white that can otherwise interfere with digestion and absorption.
Who this suits and practical tips
Eggs suit almost everyone as a versatile, affordable protein source, and three eggs make a genuinely substantial breakfast on their own before any additions. They're a less complete protein option only in the sense that a varied diet across the day, rather than any single food, is what covers all nutritional bases.
Buy eggs in the size that matches your goals — extra-large if you want to maximise protein per egg, medium if cost matters more — and store them in the fridge rather than at room temperature in the UK, where refrigeration is standard practice for shop-bought eggs.

Frequently asked questions
- Is 3 eggs a day too much?
- Current mainstream NHS guidance does not set a specific daily egg limit for most healthy people. Anyone managing cholesterol or a medical condition should follow their own clinician's advice rather than general guidance.
- Are egg whites better than whole eggs for protein?
- They are more protein-dense per calorie, but whole eggs carry vitamins, choline and healthy fats that the white alone does not provide. Many people use a mix of both rather than choosing one exclusively.
- How much protein is in 3 boiled eggs?
- The same as any other cooking method — roughly 18g to 19g for three large eggs, since boiling doesn't change the protein content, only the texture and safety of the egg.
- Do egg yolks have protein too?
- Yes — the yolk contributes around 40% of an egg's total protein, alongside most of its fat, vitamins and choline, so discarding the yolk removes a meaningful share of the egg's protein as well as its other nutrients.
