You’re staring at the frying pan. Maybe you’re on a low-sodium diet because your doctor mentioned your blood pressure, or maybe you're just trying to be a bit more "wellness-conscious" this year. You crack a large grade A egg. You see the yolk, the white, and that satisfying sizzle. But here’s the thing most people completely ignore while they’re reaching for the salt shaker: the egg itself already has salt in it.
So, how much sodium does an egg have?
If we're talking about a standard large egg, you’re looking at about 70 milligrams of sodium.
That sounds low. It is low. In the grand scheme of a 2,300mg daily limit recommended by the American Heart Association, 70mg is a drop in the bucket. But it's not zero. Unlike a piece of broccoli or an apple, eggs are one of the few "single-ingredient" foods that naturally contain a measurable amount of sodium without any processing.
Where is the Salt Hiding?
It’s almost entirely in the white.
If you separate the egg, the yolk only holds about 8mg of that sodium. The rest? It’s all in the albumen. Nature designed the egg white to be a protective, nutrient-rich environment for a developing embryo, and that includes a specific balance of electrolytes. Sodium is one of them.
Interestingly, if you size up to a Jumbo egg, that number climbs toward 90mg or 100mg. It’s a volume game. If you eat three eggs for breakfast—which is a pretty standard "hungry morning" serving—you’ve already consumed 210mg of sodium before you even touch the salt grinder.
How Much Sodium Does an Egg Have Compared to Other Proteins?
Context matters. If you’re worried about 70mg, you should probably look at what else is on the plate.

A single slice of deli turkey can easily hit 450mg. A piece of cheddar cheese? About 180mg. When you compare an egg to processed breakfast meats like bacon or sausage, the egg looks like a nutritional saint. Two slices of bacon can pack 300mg of sodium, and that’s for the "low sodium" variety. Most standard brands are much higher.
Basically, the egg isn't the problem. The problem is usually what we do to the egg.
Think about a classic diner scramble. The chef likely adds a pinch of salt to the bowl before whisking. Then they cook it in salted butter. Then they might top it with cheese. By the time that "70mg egg" hits your table, it might be pushing 400mg or 500mg. That’s a massive jump.
The USDA Data and Reality
According to the USDA FoodData Central database, a large, raw, whole egg contains exactly 71mg of sodium. This stays relatively stable regardless of whether the egg is organic, cage-free, or conventional. The hen’s diet can change the fatty acid profile—like those high-omega-3 eggs you see for five dollars a dozen—but the sodium content remains remarkably consistent.
People get confused about "natural" versus "added." Your body doesn't necessarily care where the sodium comes from once it’s in your system, but it’s helpful to know that the sodium in an egg is "intrinsic." It's part of the food's cellular structure.
Why We Care About 70 Milligrams
Sodium is a tricky beast. We need it for nerve function and muscle contraction. We’d die without it. But most Americans consume about 3,400mg a day, which is way over the limit.
If you are managing hypertension or Meniere's disease, every milligram counts. When you’re on a strict 1,500mg-a-day "Heart Healthy" protocol, three eggs take up 14% of your entire day’s allowance. That’s not a deal-breaker, but it means you have to be careful with the toast and the hot sauce.

Cooking Methods Matter More Than You Think
How you cook it changes the final tally.
- Hard-boiled: 70mg. You aren't adding anything to the water that penetrates the shell significantly.
- Poached: 70mg (unless you salt the poaching water heavily).
- Fried in Unsalted Butter: 70mg.
- Fried in Salted Butter: Add about 30-50mg.
- Omelet with Feta: You’re looking at an extra 300mg minimum.
Most people find that eggs are "flat" without salt. It’s because eggs are high in fats and proteins that coat the tongue; you need an acid or a mineral to cut through that richness.
The "Hidden" Sodium in Egg Substitutes
This is where things get wild. If you’re using those liquid egg substitutes in a carton because you’re worried about cholesterol, you might be accidentally spiking your salt intake.
Many liquid egg products use stabilizers and flavorings to make them taste more like "real" eggs. Check the label. Some of these products have upwards of 150mg to 200mg per serving. You’re literally doubling the sodium to avoid the yolk. Is it worth it? Maybe for your heart, but maybe not for your blood pressure. It's a trade-off.
What About Different Birds?
Just for fun, let's look at the variety.
A tiny quail egg has about 13mg of sodium. You’d need to eat five or six of them to equal one chicken egg, so the math stays roughly the same.
A duck egg, which is much larger and richer, has about 145mg of sodium. Duck eggs have a higher fat content and a much larger white-to-yolk ratio by mass, which explains the jump. If you’re at a fancy brunch and see duck eggs on the menu, just know you’re starting with a higher baseline.

Beyond the Salt: The Full Picture
An egg is a powerhouse. You get 6 grams of protein. You get choline for your brain. You get lutein for your eyes. Focusing purely on the 70mg of sodium is like refusing to see a movie because the ticket has a tiny smudge on it.
The real secret to managing sodium with eggs is using herbs. Honestly, if you throw some fresh chives, cracked black pepper, or a squeeze of lemon juice on a soft-scrambled egg, you won't even miss the salt. Or try nutritional yeast—it gives a "cheesy" flavor with a fraction of the sodium found in actual cheddar.
Actionable Strategy for a Low-Sodium Breakfast
If you need to keep your numbers low, don't ditch the eggs. Change the environment.
- Swap the Bread: Most store-bought bread has 150mg per slice. Use a corn tortilla (usually 10mg) or just eat the eggs with sliced avocado.
- Ditch the "Big Three": Bacon, sausage, and ham are salt bombs. If you need meat, use leftover unseasoned chicken breast or even a bit of ground turkey sautéed with fennel seeds.
- The "Top-Only" Rule: Instead of mixing salt into the eggs while they cook, sprinkle a tiny bit of flaky sea salt on top after they are on the plate. You’ll taste the salt more intensely because it hits your tongue directly, allowing you to use about half as much.
- Read the Butter Label: "Slightly salted" is a lie. Use unsalted butter or a high-quality olive oil.
Eggs are one of the most perfect foods on the planet. They are cheap, versatile, and packed with vitamins. Knowing that a large egg has 70mg of sodium isn't a reason to stop eating them; it's just a tool to help you build a better plate.
Start paying attention to the labels on your "sides." The egg is rarely the villain in the story of high blood pressure. It’s usually the guest star in a very salty play.
Keep your portions in check, use fresh aromatics, and you can enjoy your eggs every single morning without worrying about the salt police knocking on your door.
Next Steps for Your Kitchen:
Check your pantry for "hidden" sodium sources that you usually pair with eggs. Look at the labels of your favorite hot sauce, ketchup, and bread. If your hot sauce has 100mg per teaspoon, that’s where you should start cutting back, rather than worrying about the natural sodium found in the egg itself.
