Have you ever wondered why your doctor mentions copper when talking about your diet? Most of us obsess over iron, calcium, or vitamin D — but copper? That often gets pushed to the back burner. Yet, this essential trace mineral plays a surprisingly powerful role in your body’s everyday functions.
From keeping your bones strong to supporting your immune system and even helping your body produce energy, copper is quietly doing heavy lifting behind the scenes. And the good news? You don’t need supplements if you know which foods to eat.
In this article, we will explore the 30 best foods high in copper and help you figure out how to easily work them into your daily meals.
What Exactly Is Copper and Why Does Your Body Need It?
Copper is classified as an essential trace mineral — “essential” because your body absolutely needs it to function properly, and “trace” because you only need it in small amounts. The recommended daily intake for adults is 900 micrograms (mcg), which might sound tiny, but the impact copper has on your health is anything but small.
Here’s a quick breakdown of what copper actually does inside your body:
- Red blood cell production — Copper works alongside iron to help your body form healthy red blood cells. Without enough copper, iron can’t do its job properly, which can lead to anemia even if your iron levels look fine on paper.
- Bone and connective tissue health — Copper is essential for the production of collagen and elastin, the proteins that keep your bones strong and your skin firm.
- Brain and nervous system support — Copper plays a key role in the synthesis of neurotransmitters and helps maintain the myelin sheath that protects your nerve fibers.
- Immune system function — Low copper levels have been linked to increased susceptibility to infections and slower wound healing.
- Energy metabolism — Copper is a component of cytochrome c oxidase, an enzyme critical to producing ATP — the energy currency of your cells.
- Antioxidant defense — Copper is part of superoxide dismutase (SOD), one of your body’s most powerful antioxidant enzymes, which protects cells from oxidative damage.
- Melanin production — It plays a role in producing melanin, the pigment responsible for hair, skin, and eye color.
Pretty impressive for a mineral you probably never think about, right?
Signs You Might Not Be Getting Enough Copper
Before we dive into the food list, it’s worth knowing what copper deficiency actually looks like. Symptoms can be subtle and easy to dismiss:
- Unexplained fatigue and weakness
- Frequent bone fractures or low bone density
- Getting sick often or taking longer to recover
- Brain fog, memory issues, or difficulty concentrating
- Premature gray hair (yes, really — copper helps produce melanin)
- Vision problems in severe cases
- Irregular heartbeat or cardiovascular irregularities
If any of these sound familiar, it’s worth talking to your doctor and getting your copper levels checked. That said, for most people, eating a varied, whole-foods diet is enough to maintain healthy copper levels. And that’s exactly what this list will help you do.
30 Best Foods High in Copper
1. Oysters — The Undisputed Copper Champion
If copper had a mascot, it would be the oyster. These briny little shellfish are so astronomically high in copper that a single 3-ounce serving of cooked oysters delivers over 4,800 mcg — more than 500% of your daily recommended intake in one sitting.
Beyond copper, oysters are packed with zinc, vitamin B12, selenium, and omega-3 fatty acids. Whether you enjoy them raw on the half shell, grilled with garlic butter, or tossed into a chowder, oysters are the single most effective food you can eat for copper. They deserve the number one spot without question.
2. Beef Liver — Nature’s Multivitamin
Organ meats have fallen out of fashion in modern Western diets, and honestly, that’s a nutritional tragedy. Beef liver is arguably the most nutrient-dense food on earth. A 3-ounce serving packs a staggering 12,400 mcg of copper — nearly 14 times the daily recommended amount.
It’s also overflowing with vitamin A, vitamin B12, iron, folate, and high-quality protein. If you can get over any mental barriers around organ meats, eating beef liver once or twice a week could genuinely be one of the best dietary decisions you make. You can try it as a pâté on whole grain toast or sautéed with onions and herbs.
3. Dark Chocolate and Cocoa Powder
Here’s the nutrition fact that makes everyone smile. Dark chocolate (70% cacao or higher) contains approximately 1,765 mcg of copper per 100 grams. Raw cocoa powder is equally impressive, making your morning hot cocoa or a square of dark chocolate after dinner a surprisingly smart health choice.
Dark chocolate also delivers magnesium, iron, flavonoids, and powerful antioxidants. Just remember — quality matters here. The darker and less processed the chocolate, the better the nutritional profile. And moderation is still important, even when chocolate is technically healthy.
4. Shiitake Mushrooms — The Plant-Based Powerhouse
For anyone eating a plant-based or vegetarian diet, shiitake mushrooms are one of the very best copper sources available. A half-cup of cooked shiitake mushrooms provides around 1,300 mcg of copper, making them competitive with many animal-based sources.
They also contain beta-glucans (compounds that support immune function), B vitamins, and selenium. You can add them to stir-fries, ramen, soups, or sauté them with garlic and soy sauce as an incredibly satisfying side dish. These mushrooms are a staple worth keeping in your kitchen year-round.
5. Lobster — A Luxurious Copper Source
Yes, lobster makes the list — and for good reason. A 3-ounce serving of cooked lobster provides approximately 1,600 mcg of copper. It’s also rich in lean protein, selenium, zinc, and B12.
While it may not be your Tuesday night dinner, treating yourself to lobster occasionally is both a culinary delight and a genuine health investment. Lobster bisque, lobster rolls, or simply steamed with drawn butter — all copper-rich and all wonderful.
6. Cashews
Of all the nuts, cashews are among the richest in copper. A 1-ounce handful of cashews delivers around 622 mcg — nearly 70% of your daily need in a small snack. They’re also loaded with healthy monounsaturated fats, magnesium, zinc, and plant-based protein.
Cashews are incredibly versatile, too. Snack on them raw, blend them into creamy cashew butter, soak them to make dairy-free sauces, or toss them into curries and stir-fries. They’re one of the easiest high-copper foods to work into your daily routine.
7. Sunflower Seeds
These tiny seeds are a nutritional goldmine. One ounce of sunflower seeds provides approximately 519 mcg of copper, along with vitamin E, selenium, magnesium, and healthy fats.
Sprinkle them over salads, blend them into homemade trail mix, or add sunflower seed butter to your smoothies. They’re inexpensive, widely available, and incredibly easy to incorporate into meals or snacks throughout the day.
8. Spirulina
If you’re a smoothie person, spirulina is your copper-boosting best friend. This blue-green algae provides around 428 mcg of copper per tablespoon, and it’s also one of the most protein-dense plant foods in existence.
It’s also rich in B vitamins, iron, and chlorophyll. A teaspoon or two in your morning smoothie alongside banana, mango, and almond milk barely affects the flavor but dramatically boosts the nutritional value. It’s one of those small habits with outsized benefits.
9. Crab
Crab is another shellfish superstar for copper, offering around 624 mcg per 3-ounce serving. Dungeness crab is particularly notable. Like other shellfish, it also provides excellent lean protein, selenium, and B12.
You can enjoy it in crab cakes, a simple crab salad with avocado, crab-stuffed mushrooms, or even in a classic seafood pasta. It’s one of those foods that feels indulgent while actually being incredibly nutritious.
10. Lentils
Lentils are the unsung heroes of the legume world, and they deserve far more credit than they get. One cooked cup of lentils provides approximately 497 mcg of copper, plus an impressive amount of fiber, folate, plant-based protein, and iron.
They’re also one of the most affordable foods on this entire list. Red lentil soup, French lentil salad, lentil dal — there are hundreds of amazing recipes to explore. If lentils aren’t already a regular in your kitchen, let this be your sign.
11. Avocado
You’re probably already eating avocados regularly — because everyone is. But here’s another reason to love them: one whole avocado provides approximately 416 mcg of copper, along with heart-healthy monounsaturated fats, potassium, fiber, and vitamin K.
Whether it’s avocado toast, guacamole, sliced into salads, or blended into a chocolate mousse (yes, that’s a thing and it’s delicious), avocados are a copper-rich food that fits seamlessly into almost any eating style.
12. Sesame Seeds and Tahini
Don’t underestimate these tiny seeds. One ounce of sesame seeds delivers approximately 730 mcg of copper — more than most nuts. Tahini, the paste made from ground sesame seeds, carries the same impressive nutritional profile.
Use tahini to make hummus, drizzle it over roasted vegetables, blend it into salad dressings, or swirl it into oatmeal. It’s one of those ingredients that quietly elevates both the flavor and nutrition of nearly any dish it touches.
13. Soybeans and Edamame
Cooked soybeans provide around 700 mcg of copper per cup, making them one of the best plant-based options available. Edamame — young, green soybeans — is equally nutritious and makes for a wonderfully satisfying snack.
Beyond copper, soybeans are complete protein sources, rich in isoflavones, fiber, and calcium. Edamame with a pinch of sea salt is one of the most nutritious snacks you can eat, full stop.
14. Salmon
Salmon already has a stellar reputation thanks to its omega-3 fatty acids, but it also delivers a meaningful 250 mcg of copper per 3-ounce serving. It’s rich, flavorful, versatile, and one of those rare foods that manages to be both luxurious and deeply healthy at the same time.
Bake it with lemon and herbs, pan-sear it with honey glaze, or serve it cold in a Niçoise salad. However you enjoy salmon, you’re doing your body a genuine favor.
15. Whole Wheat and Wheat Bran
Swapping white bread and refined grains for whole wheat is one of the simplest dietary upgrades you can make. Wheat bran, in particular, provides around 400 mcg of copper per half-cup. Whole wheat bread and whole grain pasta also contribute meaningfully to your daily copper intake.
Plus, you’ll be getting more fiber, B vitamins, and other minerals with every meal. A simple but powerful swap.
16. Almonds
A classic snack for a reason. One ounce of almonds provides roughly 290 mcg of copper, plus vitamin E, magnesium, calcium, and fiber. Almond butter on whole-grain toast is both a delicious breakfast and a copper-rich one.
Keep a small container in your bag, desk drawer, or car for moments when hunger strikes and you need something nutritious on the go.
17. Tofu
For vegetarians and vegans, tofu is a reliable copper contributor, delivering 200–400 mcg per half-cup depending on firmness. Firm tofu works brilliantly in stir-fries and curries, while silken tofu can be blended into smoothies, soups, and even desserts.
It absorbs flavors beautifully, which means it’s one of the most culinarily flexible proteins available — plant-based or otherwise.
18. Sweet Potatoes
Sweet potatoes are comfort food at its nutritious best. A medium sweet potato provides approximately 360 mcg of copper, alongside an enormous amount of beta-carotene (which your body converts to vitamin A), vitamin C, potassium, and fiber.
Roasted, mashed, baked whole, turned into fries, or cubed into a warming soup — sweet potatoes are one of those foods that feel like a treat while genuinely nourishing your body.
19. Lamb
For red meat eaters, lamb provides around 180–200 mcg of copper per 3-ounce serving, along with zinc, B12, and iron. It’s a flavorful, nutrient-rich option that doesn’t get nearly as much attention as beef in Western diets.
Lamb chops, slow-cooked lamb shoulder, Moroccan lamb tagine — there are incredible ways to prepare this protein that go far beyond your typical dinner rotation.
20. Chickpeas
One cooked cup of chickpeas delivers around 580 mcg of copper. This makes them one of the copper-richest legumes available. They’re also packed with fiber, folate, manganese, and plant-based protein.
The versatility of chickpeas is almost unmatched — homemade hummus, roasted chickpea snacks, chickpea curry, Mediterranean salads, or even blended into baked goods for added protein. These little legumes deserve a permanent spot in your pantry.
21. Blackstrap Molasses
This is the one that surprises people most. One tablespoon of blackstrap molasses provides roughly 450 mcg of copper, along with iron, calcium, magnesium, and potassium. It’s essentially the nutritional byproduct of sugar refining, concentrating many of the minerals that get stripped from refined sugar.
You can stir it into oatmeal, add it to marinades, mix it into baked beans, or swirl it into warm milk with cinnamon. It has a bold, slightly bitter-sweet flavor that adds depth to many dishes.
22. Swiss Chard
This gorgeous, colorful leafy green provides roughly 300 mcg of copper per cooked cup and is one of the most nutrient-dense vegetables you can find. It’s also rich in vitamins K, A, and C, along with magnesium and potassium.
Sauté it simply with olive oil and garlic, add it to frittatas, fold it into pasta dishes, or use it as a base for hearty grain bowls. Swiss chard is a legitimate superfood that deserves more attention.
23. Pine Nuts
These small but mighty nuts contain approximately 1,300 mcg of copper per 100 grams, making them one of the highest copper nuts available. They’re also rich in manganese, vitamin E, and magnesium.
While pine nuts are expensive, a small amount goes a long way. Toast them and add to salads, blend them into pesto, or sprinkle over roasted vegetables. Their buttery, delicate flavor is unlike any other nut.
24. Black Beans
A staple in Latin American and Caribbean cooking, one cooked cup of black beans delivers approximately 360 mcg of copper. They’re also fantastic sources of fiber, folate, and plant-based protein.
Black bean tacos, black bean soup, rice and beans, burrito bowls — the applications are endless and universally delicious. These beans are affordable, filling, and genuinely good for you.
25. Quinoa
One cooked cup of quinoa provides around 355 mcg of copper, and unlike most plant foods, it’s a complete protein — containing all nine essential amino acids. It’s also gluten-free, making it a great option for people with celiac disease or gluten sensitivity.
Use it as a base for grain bowls, serve it alongside roasted vegetables, stir it into soups, or even cook it like oatmeal for a warm, nutty breakfast porridge.
26. Oats
Your humble morning bowl of oatmeal delivers approximately 170–300 mcg of copper, depending on serving size and preparation. When you top it with cashews, sunflower seeds, and dried apricots, you can turn breakfast into a genuine copper-rich meal without even trying.
Overnight oats, warm oatmeal bowls, baked oatmeal, or even oat-based energy balls — oats are an endlessly adaptable staple that quietly supports your mineral intake every single day.
27. Chicken Liver
If beef liver feels too intense for your palate, chicken liver is a wonderful alternative — milder in flavor but still nutritionally remarkable. A 3-ounce serving provides around 3,000 mcg of copper, along with vitamin A, B12, iron, and folate.
Try chicken liver pâté on whole grain crackers, or sauté it with onions, garlic, and a splash of balsamic vinegar for a surprisingly elegant dish. It’s one of the most affordable, nutrient-dense proteins available.
28. Broccoli
A classic for a reason. One cooked cup of broccoli provides around 100 mcg of copper — modest compared to others on this list, but consistent and incredibly easy to include daily. It’s also packed with vitamin C, vitamin K, fiber, and sulforaphane, a compound linked to cancer prevention.
Steam it, roast it, add it to stir-fries, or eat it raw with hummus as a snack. Broccoli is one of those non-negotiable vegetables that should appear in your diet multiple times a week.
29. Dried Fruits (Apricots, Prunes, Raisins)
Dried apricots provide around 170 mcg of copper per half-cup, along with iron, potassium, and fiber. Prunes and raisins contribute similarly. While they’re not the highest copper sources on the list, dried fruits are a practical, portable, and naturally sweet way to supplement your intake.
Add them to oatmeal, trail mix, grain salads, or simply snack on them throughout the day. They’re especially useful for people who struggle to eat enough fruits and vegetables in their daily diet.
30. Amaranth
Rounding out our list is amaranth, an ancient grain that most people have never tried but absolutely should. One cooked cup of amaranth delivers approximately 290 mcg of copper, along with impressive amounts of magnesium, phosphorus, manganese, and iron.
Like quinoa, it’s a complete protein and naturally gluten-free. Cook it as a porridge, use it as a rice substitute, or pop it like popcorn for a crunchy, nutritious snack. It has a slightly nutty, earthy flavor that pairs beautifully with savory and sweet preparations alike.
Tips for Maximizing Copper Absorption
Getting copper from food is the best approach, but how you combine foods and manage other nutrients can affect how well your body absorbs it:
- Avoid high-dose zinc supplements unless directed by a doctor — zinc and copper compete for absorption, and too much zinc can deplete copper levels.
- Vitamin C can enhance copper absorption, so pairing copper-rich foods with citrus or bell peppers is a smart move.
- Cooking in cast iron or copper cookware can slightly increase the mineral content of foods.
- Store acidic foods separately — acidic foods stored in copper containers can leach too much copper (which can be harmful in excess).
- If you take iron supplements, be aware that very high iron intake may interfere with copper absorption.
Who Might Be at Risk for Copper Deficiency?
Most people who eat a varied diet get enough copper. However, certain groups may be more at risk:
- People with celiac disease or other malabsorption conditions
- Those taking high-dose zinc supplements (zinc competes with copper absorption)
- Individuals on very restrictive diets
- Premature infants
- People who have had gastric bypass surgery
If you think you might be deficient, it’s always best to speak with your healthcare provider before jumping to supplements. Food-first approaches are generally safer and more effective.
Can You Get Too Much Copper?
Yes, though it’s rare from food alone. The tolerable upper intake level (UL) for adults is 10,000 mcg (10 mg) per day. Copper toxicity is more likely to occur from drinking water through corroded copper pipes or from taking excessive supplements.
Symptoms of copper toxicity can include nausea, vomiting, liver damage, and neurological issues. As always, balance is key.
Final Thoughts
Copper might not get the spotlight like vitamin C or calcium, but it’s just as essential to your overall health. The beautiful thing is that so many delicious, everyday foods are naturally rich in copper.
You don’t need to be a nutrition expert to eat well. Just start making small, consistent choices — a handful of nuts here, a serving of lentil soup there — and your body will thank you.
