If you’ve ever tried to plan meals around both iron and calcium, you know it’s trickier than it sounds — the two minerals don’t always show up in the same foods, and sometimes they even compete with each other in your gut.
I’ve pulled together 44 foods that genuinely deliver one or both, organized into practical categories so you can build meals that cover your bases. Nutrition numbers below are approximate and based on typical serving sizes — always check a label or talk to your doctor for your specific needs.
Key Takeaways
- Dark leafy greens, dairy, canned fish with bones, legumes, and fortified foods are the biggest overlap zone for both iron and calcium.
- Calcium can interfere with iron absorption when eaten in the same meal, so timing matters more than most people realize.
- Heme iron from meat and fish absorbs far better than non-heme iron from plants, but pairing plant iron with vitamin C helps close the gap.
- Fortified cereals, breads, and plant milks are an easy way to hit both targets without cooking from scratch.
- People with higher needs — including pregnant women, menstruating women, and vegetarians — often need to be more deliberate about food choices.
Leafy Greens and Vegetables
Dark, leafy vegetables are some of the only plant foods that genuinely deliver both calcium and iron in the same bite. They’re not a replacement for dairy or meat sources, but they add up fast when you eat them often — see this iron rich foods list for more plant-based options.
1. Spinach
Approximate nutrition: about 6.4 mg iron and 245 mg calcium per 1 cup cooked.
I toss a big handful into eggs or a smoothie almost daily — cooking shrinks the volume so you get more nutrition per bite than raw.
2. Kale
Approximate nutrition: roughly 1 mg iron and 177 mg calcium per 1 cup cooked.
Kale’s calcium is actually well absorbed compared to spinach, since it’s lower in the compounds that block mineral uptake. Massage it with a little olive oil before adding to salads to soften the leaves.
3. Collard Greens
Approximate nutrition: about 268 mg calcium and 2.2 mg iron per 1 cup cooked.
This is one of the best plant calcium sources out there. I simmer them low and slow with garlic and a splash of vinegar until tender.
4. Swiss Chard
Approximate nutrition: around 4 mg iron and 102 mg calcium per 1 cup cooked.
Chard wilts down quickly in a hot skillet, which makes it an easy last-minute side. The stems are edible too — just chop and cook them a minute or two longer than the leaves.
5. Broccoli
Approximate nutrition: about 62 mg calcium and 1 mg iron per 1 cup cooked.
Broccoli’s vitamin C content actually helps your body absorb non-heme iron from other foods on your plate, which is a nice bonus. It’s also one of the easier greens to sneak into iron rich foods for kids when it’s roasted until the edges crisp.
6. Bok Choy
Approximate nutrition: roughly 158 mg calcium and 1.8 mg iron per 1 cup cooked.
I stir-fry bok choy hot and fast so the stalks stay crisp while the leaves just wilt. It’s mild enough to work in almost any noodle or rice bowl.
Dairy and Fortified Milk Alternatives
Dairy is the most reliable calcium source for most people, and fortified plant milks have closed the gap considerably. Iron content here is generally low, so pair these with an iron-rich food elsewhere in the day — check out high calcium foods for a deeper dive.
7. Milk
Approximate nutrition: about 300 mg calcium per 1 cup, with very little iron.
One thing that trips people up: drinking milk with an iron-rich meal can actually reduce how much iron you absorb. I try to have dairy at a separate meal from my iron sources when I’m being deliberate about it.
8. Yogurt
Approximate nutrition: roughly 300 to 450 mg calcium per 1 cup, depending on the type.
Plain Greek yogurt is my go-to breakfast base — it’s thicker, higher in protein, and works savory or sweet.
9. Cheddar Cheese
Approximate nutrition: about 200 mg calcium per 1 ounce.
A small block of cheddar melts beautifully into eggs, grain bowls, or a quick quesadilla. Watch the sodium if you’re eating it daily, since it adds up fast.
10. Cottage Cheese
Approximate nutrition: around 138 mg calcium per 1 cup.
Cottage cheese has less calcium than yogurt or milk but brings a serious protein boost. I eat it straight with fruit or blend it into a smoothie for extra body.
11. Fortified Orange Juice
Approximate nutrition: about 350 mg calcium per 1 cup fortified juice.
This is a smart pick for anyone who’s dairy-free, and the vitamin C in the juice happens to boost iron absorption from whatever else you’re eating that morning. Check the label since fortification levels vary by brand — see foods high in calcium vitamin D for more fortified options.
12. Fortified Soy Milk
Approximate nutrition: about 300 mg calcium and roughly 1 mg iron per 1 cup, depending on brand.
Soy milk is the plant milk closest to cow’s milk in protein, which makes it my default recommendation for anyone switching over. Shake the carton well since calcium can settle at the bottom.
Fish and Seafood
Seafood is an underrated source for both minerals, especially the canned varieties where you eat the soft bones. It’s also one of the better categories for B12, which works alongside iron in your body’s red blood cell production — see this B12 rich foods list for the full picture.
13. Canned Sardines
Approximate nutrition: about 325 mg calcium and 2.5 mg iron per 3 ounces, with bones included.
Sardines are one of my favorite pantry staples for exactly this reason — the bones are soft enough to eat and packed with calcium.
14. Canned Salmon
Approximate nutrition: roughly 180 mg calcium and 0.9 mg iron per 3 ounces, with bones included.
Mash canned salmon with a little mayo and lemon for a fast lunch, bones and all. It’s far cheaper than fresh fillets and just as nutritious for this purpose.
15. Oysters
Approximate nutrition: about 8 mg iron per 3 ounces cooked, along with a strong dose of zinc.
Oysters aren’t a big calcium source, but the iron content is hard to beat outside of organ meats. I always cook them thoroughly, since raw shellfish carries a real food-safety risk for some people.
16. Mussels
Approximate nutrition: around 5.7 mg iron per 3 ounces cooked.
Steamed mussels in a garlicky broth are one of the fastest seafood dinners I make. Discard any that stay closed after cooking.
17. Clams
Approximate nutrition: roughly 23.8 mg iron and 78 mg calcium per 3 ounces cooked.
Clams have one of the highest iron counts of any common food, which surprises most people. A simple linguine alle vongole covers a huge chunk of your daily iron in one bowl.
18. Mackerel
Approximate nutrition: about 1.6 mg iron and 15 mg calcium per 3 ounces cooked.
Mackerel’s mineral numbers are modest, but its omega-3 content makes it worth including regularly. I broil it skin-side up until the skin crisps.
Meat and Poultry
Meat delivers heme iron, the form your body absorbs most efficiently, though calcium levels stay low across this group. This is a key category for anyone with higher iron needs — see foods high in iron for pregnancy and foods high in iron for women for guidance specific to those needs.
19. Beef Liver
Approximate nutrition: about 5 mg iron per 3 ounces cooked, plus a very high B12 content.
Liver isn’t for everyone, but a small serving once a week is one of the most concentrated iron sources you can eat. I pan-sear it with onions to soften the strong flavor.
20. Ground Beef
Approximate nutrition: roughly 2.2 mg iron per 3 ounces cooked, 85% lean.
This is the iron source most home cooks already have in rotation. I brown it with a bit of tomato paste to deepen the flavor in weeknight chili.
21. Chicken Thighs
Approximate nutrition: about 1.1 mg iron per 3 ounces cooked.
Dark meat chicken has noticeably more iron than breast meat. I keep the skin on for roasting, then remove it if I’m watching fat intake.
22. Turkey
Approximate nutrition: roughly 1.4 mg iron per 3 ounces cooked dark meat.
Ground turkey thigh meat is a good swap for beef in tacos or meatballs when you want a leaner option without losing much iron.
23. Lamb
Approximate nutrition: about 1.8 mg iron per 3 ounces cooked.
Lamb shoulder or leg braises into something tender and rich with very little hands-on effort. It’s a nice change of pace if beef and chicken feel repetitive.
Legumes and Soy Foods
Beans, lentils, and soy foods are the backbone of plant-based iron and calcium intake, and they’re inexpensive enough to eat several times a week. For a full strategy on building meals this way, see iron rich foods for vegetarians.
24. Lentils
Approximate nutrition: about 6.6 mg iron per 1 cup cooked.
Lentils cook faster than any other dried legume and don’t need soaking. I add a squeeze of lemon at the end, since the vitamin C helps your body absorb the iron better.
25. Chickpeas
Approximate nutrition: roughly 4.7 mg iron and 80 mg calcium per 1 cup cooked.
Chickpeas work in everything from hummus to roasted snacks. I always rinse canned ones well to cut down on the added sodium.
26. Kidney Beans
Approximate nutrition: about 3.9 mg iron and 50 mg calcium per 1 cup cooked.
These hold their shape well in chili and stews, which is why they’re my default bean for slow-cooked dishes. Always cook dried kidney beans thoroughly, since undercooked ones carry a natural toxin.
27. Black Beans
Approximate nutrition: roughly 3.6 mg iron and 46 mg calcium per 1 cup cooked.
Black beans have a creamier texture than kidney beans, which makes them great blended into soups or mashed for burritos. Canned versions are just as nutritious as dried.
28. Edamame
Approximate nutrition: about 3.5 mg iron and 98 mg calcium per 1 cup cooked.
Steamed edamame in the pod makes an easy snack that also happens to hit both minerals. I keep a bag in the freezer for exactly this reason.
29. Calcium-Set Tofu
Approximate nutrition: roughly 250 to 430 mg calcium and 3.4 mg iron per half cup, depending on the brand.
Not all tofu is made the same way — check the label for ‘calcium sulfate’ in the ingredients, since that’s what boosts the calcium count so much. Firm varieties hold up well to searing.
Nuts, Seeds and Nut Butters
Nuts and seeds are compact sources of both minerals and easy to add to meals without any cooking at all. They’re also a solid source of magnesium, which works closely with these two minerals — see foods high in iron and magnesium for more.
30. Sesame Seeds and Tahini
Approximate nutrition: about 130 mg calcium and 2.7 mg iron per 2 tablespoons of tahini.
Tahini is my favorite way to eat sesame seeds since a spoonful blends straight into dressings or hummus. Whole seeds sprinkled over roasted vegetables work too.
31. Almonds
Approximate nutrition: roughly 76 mg calcium and 1 mg iron per 1 ounce.
A small handful of almonds is an easy afternoon snack, and almond butter spreads onto toast almost as well as peanut butter.
32. Pumpkin Seeds
Approximate nutrition: about 2.5 mg iron and 18 mg calcium per 1 ounce.
Toasted pumpkin seeds are one of the higher-iron seeds out there. I toss them over soups and salads for crunch.
33. Chia Seeds
Approximate nutrition: roughly 179 mg calcium and 2.2 mg iron per 1 ounce.
Chia seeds thicken liquid into a pudding-like texture overnight, which makes them an easy make-ahead breakfast. They’re one of the few seeds that hit both minerals hard.
34. Cashews
Approximate nutrition: about 1.9 mg iron and 10 mg calcium per 1 ounce.
Cashews are milder and creamier than most nuts, which is why they blend so well into dairy-free sauces. Soak them in warm water first if you’re making a cashew cream.
35. Peanut Butter
Approximate nutrition: roughly 0.6 mg iron and 15 mg calcium per 2 tablespoons.
Peanut butter isn’t a powerhouse for either mineral, but it’s such a regular part of most diets that it still contributes meaningfully over a week. Choose one without added sugar if you can.
Fortified Grains, Soy and Whole Grains
This is where food manufacturers do a lot of the heavy lifting for iron, and where whole grains quietly add calcium and iron together. Fortified products can vary a lot by brand, so it’s always worth checking the nutrition label.
36. Fortified Breakfast Cereal
Approximate nutrition: up to 18 mg iron per 1 cup in cereals fortified to 100% of the daily value, with calcium varying widely by brand.
Fortified cereal is genuinely one of the easiest ways to hit your iron target in one bowl. Pair it with milk or fortified soy milk to add calcium at the same time.
37. Enriched Whole Wheat Bread
Approximate nutrition: about 1.8 mg iron and 40 mg calcium per 2 slices.
Most US bread is enriched with iron by law, which is why a basic sandwich contributes more than people expect. Whole grain versions add fiber on top.
38. Quinoa
Approximate nutrition: roughly 2.8 mg iron and 31 mg calcium per 1 cup cooked.
Quinoa is a complete protein and cooks in about 15 minutes, which makes it my go-to grain swap when I want more nutrition than rice offers.
39. Oatmeal
Approximate nutrition: up to 10 mg iron per 1 cup of fortified instant oatmeal, or around 2 mg for plain rolled oats.
Check the package carefully, because instant fortified packets carry far more iron than plain rolled oats cooked from scratch. Both are still a solid breakfast base.
40. Tempeh
Approximate nutrition: about 4.5 mg iron and 184 mg calcium per 1 cup.
Tempeh’s fermentation gives it a firmer, nuttier texture than tofu, and it holds up better on the grill. I marinate slices for at least 20 minutes before cooking to let the flavor soak in.
Fruits and Other Everyday Foods
A handful of fruits and pantry staples round out the list with smaller but genuinely useful amounts of both minerals. They’re easy to fold into recipes you’re probably already making — see high fiber foods list for how dried fruit fits into your fiber intake too.
41. Dried Apricots
Approximate nutrition: about 1.7 mg iron and 30 mg calcium per half cup.
Dried apricots are a good sweet-tart snack on their own or chopped into oatmeal. Buy unsulfured if you’re sensitive to sulfites.
42. Raisins
Approximate nutrition: roughly 1.4 mg iron and 41 mg calcium per half cup.
A small box of raisins is an easy add-in for trail mix or morning cereal. They’re calorie-dense, so portion control matters if you’re watching intake.
43. Blackstrap Molasses
Approximate nutrition: about 3.5 mg iron and 172 mg calcium per 1 tablespoon.
This is one of the most concentrated plant sources of both minerals I know of, tablespoon for tablespoon. I stir it into oatmeal or baked beans for a deep, almost smoky sweetness.
44. Dark Chocolate
Approximate nutrition: about 3.3 mg iron and 22 mg calcium per 1 ounce of 70 to 85% cacao chocolate.
Dark chocolate is a genuinely fun way to close out this list — the higher the cacao percentage, generally the more iron it carries.
Frequently Asked Questions
Can I eat iron-rich and calcium-rich foods at the same meal?
You can, but calcium can reduce how much non-heme iron your body absorbs from that same meal. If you're actively trying to boost iron levels, it can help to space high-calcium foods like milk or cheese away from your main iron sources.
What is the best combination food for both iron and calcium?
Blackstrap molasses, tempeh, calcium-set tofu, and canned sardines with bones are among the few foods that deliver meaningful amounts of both minerals in a single serving.
Do vegetarians need to worry about iron and calcium together?
Vegetarians rely more on non-heme iron, which absorbs less efficiently than the heme iron in meat, so pairing plant iron sources with vitamin C rich foods can help. Our guide to iron rich foods for vegetarians covers this in more detail.
How much iron and calcium do adults need daily?
Needs vary by age and sex, and are higher during pregnancy; the NIH Office of Dietary Supplements publishes current recommended intakes for both minerals. It's worth checking those figures directly or discussing your personal needs with a healthcare professional.
Should I take an iron or calcium supplement instead of relying on food?
Food sources are generally preferred first, but some people with diagnosed deficiencies may need supplements under medical guidance. Anyone with a known deficiency, or who is pregnant, should consult a healthcare professional before starting supplements.
