One large chicken egg contains about 0.88 mg of iron, which is roughly 5% of the daily value for most adults. That makes eggs a modest but consistent source of iron, especially when paired with other iron-rich foods throughout the day.
Iron in One Large Egg
According to the USDA National Nutrient Database, a single large egg provides 0.88 mg of iron whether it’s raw, poached, or fried. The cooking method barely changes the total amount: a fried egg clocks in at 0.87 mg, while poached and raw eggs both sit at 0.88 mg. So from a pure iron standpoint, cook your eggs however you prefer.
That said, the way iron is absorbed tells a more nuanced story. Egg yolk iron is better absorbed when baked than when boiled. In one study measuring how well rats maintained hemoglobin levels on different egg-yolk diets, baked egg yolk delivered about 90% of the bioavailability seen with a standard iron source, while boiled yolk came in around 61% and steamed yolk at 64%. If you’re relying on eggs as a meaningful part of your iron intake, scrambled or baked preparations may give you a slight edge over hard-boiled.
How Much Iron You Actually Need
The recommended daily intake for iron varies significantly by age and sex. Adult men aged 19 to 50 need 8 mg per day, while women in the same age range need 18 mg, more than double, primarily because of menstrual blood loss. After age 51, the recommendation drops to 8 mg for everyone. Pregnant women need the most at 27 mg per day.
A single egg covers about 11% of an adult man’s daily needs but only about 5% of a premenopausal woman’s. Two eggs at breakfast get you closer to 1.8 mg, a decent contribution but clearly not enough on its own for anyone with higher requirements.
Eggs vs. Other Iron Sources
Eggs contain heme iron, the type found in animal products that the body absorbs more readily than the non-heme iron in plants. But among heme iron sources, eggs rank relatively low. Red meat is the standout: beef muscle has been shown to boost non-heme iron absorption threefold when added to a meal, while egg white actually reduces iron absorption by about 72% compared to a protein-free meal. The iron-rich part of the egg is the yolk, not the white. If you’re eating egg whites only, you’re getting almost no iron at all.
Duck eggs are a notable alternative. Per 100 grams, cooked duck eggs provide about 20% of the daily value for iron compared to just 7% for chicken eggs. That’s nearly three times as much iron. Duck eggs are larger than chicken eggs too, so a single duck egg delivers a meaningfully bigger iron dose than its chicken counterpart.
Boosting Iron Absorption From Eggs
Your body absorbs non-heme iron more efficiently when you eat it alongside vitamin C or heme iron sources. This applies to eggs as well. Pairing your eggs with vitamin C-rich foods like tomatoes, bell peppers, or a glass of orange juice can increase how much iron your body actually takes in from the meal.
On the flip side, certain compounds interfere with iron absorption. Coffee, tea, and calcium-rich foods consumed at the same meal can reduce how much iron makes it into your bloodstream. If iron intake is a priority for you, timing matters. Eating your eggs with sautéed spinach and tomatoes is a smarter combination than washing them down with coffee and a calcium supplement.
Eggs for Infants and Children
Iron becomes especially important around 6 months of age, when babies’ iron stores from birth start to deplete and solid foods need to fill the gap. The CDC lists eggs among the heme iron foods appropriate for infants starting solids. Scrambled egg yolk is one of the easier early textures for babies to manage, and it delivers iron in its most absorbable form. Eggs alone won’t meet an infant’s iron needs, but they’re a practical part of an iron-rich diet alongside meats, poultry, and fortified cereals.
Iron Overload and Eggs
People with hemochromatosis, a condition where the body absorbs and stores too much iron, need to be careful with iron-rich foods. Interestingly, eggs are generally considered safe and even recommended as a protein source on a hemochromatosis diet. The relatively low iron content per egg, combined with compounds in egg white that actually inhibit iron absorption, makes them one of the better animal protein choices for people managing iron overload.
