Foods to help you build an iron-rich diet, from a dietitian

Discover natural ways to increase iron intake through an iron-rich diet that includes both animal and plant foods. You'll learn practical tips to improve absorption and build balanced meals.

An iron-rich diet is a luxury for millions worldwide

Even though much of today’s nutrition conversation focuses on probiotics, fasting, protein, and plant-forward eating, iron deficiency still affects millions of people worldwide. Iron is a mineral your body needs to make hemoglobin, the protein that carries oxygen in your blood.

Who is most at risk for low iron?

Although anyone can develop iron deficiency, certain groups are more likely to experience it. Think of this as the “VIP list” that nobody wants to be on, and on the plus side, the senior demographic gets a break:

• Women in their childbearing years
• Pregnant and breastfeeding women
• Young children
• Adolescent girls
• Athletes
• Vegans and vegetarians

How much iron do I need?

The Recommended Dietary Allowance for iron is based on age and sex.

	Age 19-50	Age 51-70
Men	8 mg	8 mg
Women	18 mg	8 mg
Pregnancy	27 mg
Lactation	9 mg

Common symptoms of iron deficiency

Low iron can be sneaky, showing up in ways that are easy to overlook until they pile up. Common symptoms include:

• Extreme fatigue
• Weakness or sluggishness
• Decreased focus, dizziness, or difficulty concentrating
• Irritability
• Pale skin or brittle fingernails

Important: These symptoms overlap with many other health conditions. Only a blood test from your doctor can diagnose iron-deficiency anemia.

Two simple ways to increase your iron intake

1. Enrich your daily diet with iron-rich foods

Let’s start with the basics: your body needs iron, so give it iron! A combination of animal and plant sources is an excellent way to build an iron-rich diet.

Best animal sources of iron:

• Beef
• Turkey (dark meat)
• Chicken (dark meat)
• Mollusks such as clams, oysters, mussels, cuttlefish, and octopus
• Liver
• Kidney
• Duck

Best plant sources of iron:

• Beans (pinto, lentils, soybeans, kidney beans)
• Dark leafy greens (spinach, kale, Swiss chard)
• Fortified or enriched breakfast cereals
• Whole or enriched grains (bread, rice, quinoa, couscous)

These foods can help you build an iron-rich diet even if you follow a plant-forward lifestyle.

2. Pair iron-rich foods with vitamin C

Here’s a fun fact: your body absorbs iron from animal foods 2–3 times better than from plant foods. But don’t worry, plant lovers aren’t doomed! You can boost plant-based iron absorption with two simple tricks:

• Add a little meat, fish, or poultry to the same meal.
• Combine plant foods with vitamin C-rich foods—such as citrus, berries, or bell peppers.

Here are a few tasty combos to try:

• Iron-fortified breakfast cereal + fresh berries
• Turkey or beef jerky + dried apricots or figs
• Lean beef + tomato products in chili, pasta sauce, or casseroles
• Spinach salad + dried cranberries
• Muffins with dried fruit mixed in; the vitamin C will enhance the iron absorption from the flour.
• Beans or lentils added to soups and stews, ideally with tomatoes and a protein source
• Oven-roasted kale as your new iron-rich side dish

Special considerations for when the diet is not enough

Food first is a great goal—but sometimes your body needs a little extra backup. In certain situations, like pregnancy, diagnosed iron-deficiency anemia, or when an iron-rich diet isn’t quite cutting it, your doctor may recommend an iron supplement.

That said, more is not always better here. Iron supplements are one of those things you don’t want to take “just in case” or on a whim—your stomach will not be impressed. They can cause side effects like constipation, nausea, or that lovely metallic taste that makes you question your life choices.

If you think you might need one, it’s best to check in with your doctor and get your levels tested. They can recommend the right type and dose so you can safely increase your iron intake without overdoing it.

A simple boost goes a long way

With just a few tweaks, adding more iron-rich foods to your diet and pairing them with vitamin C, you can naturally support better energy and overall health. Small changes to your meals can make a big difference in helping you increase your iron intake without sacrificing your favorite foods or buying up half the supplement aisle.
