What’s Up With Copper?

There are quite a number of ways copper can benefit you. The first of them is it provides energy to the brain and improves the functioning of the nervous system. It also helps in the production of red blood cells – it aids the process and boosts your immunity. It achieves this along with iron.

Copper also contributes to the health of bones, nerves, and even promotes iron absorption (offering an entirely different set of benefits) in a way.

Well, there’s more. Why don’t you just check them out?

What Are The Health Benefits Of Copper?

1. Boosts Your Brain Health

Copper is one important ingredient of enzymes that activate the brain’s neurotransmitters. New research indicates that adequate copper levels are essential to brain health. The brain takes in 20 percent of the oxygen you inhale. And since most copper in the body is found in the brain, the organ sure needs adequate copper (1).

Neurodegeneration in adults is often linked to an imbalance in copper levels. Also, the symptoms of copper deficiency include the inability to concentrate, lack of positivity, and poor mood which affects the overall wellness and happiness of a person.

2. Boosts Your Joint And Bone Health

Copper contributes to bone mineral density, and low levels of the mineral can lead to osteoporosis (2). It also plays a role in collagen health, which is an important structural component in our bodies and promotes youthfulness and beauty. Insufficient copper can lead to depletion of collagen, and this eventually results in joint dysfunction.

The anti-inflammatory properties of copper can also ease arthritis pain.

And, by the way, there are some claims going on about copper bracelets and how they can treat joint pains. Proponents claim that the anti-inflammatory properties of the copper in the bracelet can get transferred to the body upon contact. Let me tell you that there is no research to support this claim (3).

3. Strengthens Your Immunity

As we discussed earlier, copper, along with iron, helps in the production of red blood cells. This builds your immunity. Deficiency in copper can lead to neutropenia, which is a lower amount of white blood cells – and research says this condition can cause one to fall ill more often as it reduces endurance and delays healing. These effects are more pronounced in infants, which is why they need to have sufficient copper levels more than anyone else (4).

4. Promotes Metabolism

Copper supports over 50 enzymatic reactions that take place in your body on a daily basis. This supports a healthy metabolism.

The mineral also plays a role in the synthesis of ATP, or adenosine triphosphate – which is the body’s source of energy. Which is why deficiency of copper can lead to a sluggish metabolism.

 5. Contributes To Proper Growth And Development

Copper deficiency, unfortunately, is quite common in third world countries and is quite visible in children – where kids suffer from stunted growth and other developmental complications. This is because copper deficiency can affect joint and bone development and even the development of the brain.

Additionally, copper is also required for the oxygenation of red blood cells – and low levels of the mineral can mean your organs do not receive adequate levels of oxygen. This can lead to developmental and longevity issues. Studies show that deficiency in copper can also delay growth in infants.

6. Supports Your Thyroid Health

Copper works with potassium, zinc, calcium, and potassium (essential nutrients for thyroid health) and promotes thyroid health. As a result, it can help prevent conditions like hypothyroidism or hyperthyroidismi  A condition characterized by an overactive thyroid gland that accelerates metabolism and causes weight loss, hand tremors, etc. .

Studies suggest that how the metabolism of copper is essential to prevent or manage thyroid disease (5).

7. Delays Aging

Studies show that copper is as important to anti-aging as retinol and alpha hydroxy acidsi  A class of chemical compounds used in various skin care products that have anti-aging and exfoliating properties. . And then, there are copper peptides, a copper complex that can reduce inflammation and keep the skin looking younger and fresher. Since copper helps build collagen, and since collagen is also important to maintain skin elasticity, it should be safe to say that copper can improve skin firmness and reduce wrinkles.

Studies also state that copper stabilizes skin proteins, improving the overall skin health and vitality (6). It also helps in the production of melanin, which is the pigment that protects your skin from UV radiation.

8. Copper Can Boost Your Hair Health

Copper peptides are also known to increase the size of the hair follicles and subsequently stop hair thinning and provide strength to the strands. And since copper helps in the production of melanin, it can even prevent premature graying of hair.

These are the benefits of copper. These tell us how important the trace mineral is, don’t they? Inadequate levels of this mineral can lead to complications. Let’s see what they are.

What Are The Signs Of Copper Deficiency?

Deficiency of copper can lead to the following issues:

  • Anemia
  • Bone fractures
  • Thyroid issues
  • Osteoporosis
  • Loss of pigmentation of hair and skin
  • Menkes disease (neurodevelopmental delays in infants)

The only way to prevent copper deficiency is by ensuring you take enough of it. This takes us to the next section.

What Are The Foods Rich In Copper?

The RDA of copper is 900 mcg a day for both adults and adolescents. And the upper limit is 10 mg per day. Keeping that in mind, you can include the following foods in your diet as required:

  • Beef liver – 3 oz contains 4.49 mg, which meets 641% of the RDA.
  • Mushrooms (shitake) – 1 cup (cooked) contains 1.29 mg, which meets 184% of the RDA.
  • Cashews – 1 oz contains 0.62 mg, which meets 88% of the RDA.
  • Kale – 2 cups (raw) contain 0.48 mg, which meets 68% of the RDA.
  • Cocoa powder – 1 tablespoon (unsweetened) contains 0.41 mg, which meets 58% of the RDA.
  • Almonds – 1 oz contains 0.29 mg, which meets 41% of the RDA.
  • Avocado – ½ fruit contains 0.12 mg, which meets 17% of the RDA.
  • Dark chocolate – 1 oz contains 0.501 mg, which meets 56% of the RDA (7).

Cocoa is considered an excellent source of dietary copper. Researchers studied Hershey’s pure cocoa as it is rich in copper. This particular chocolate contains 3.8 mg of copper per 100 g of cocoa. A study involving 86 patients found that those with severely low serum copper levels (below 20 micrograms/dl) were given 30-45 g of cocoa daily, while those with slightly higher levels (20-77 mg/dl) received 10 g of cocoa each day. The results found that serum copper levels increased significantly with cocoa supplementation. This may improve the symptoms of anemia and neutropenia associated with copper deficiency. The study further suggested that the high copper content in cocoa may help treat copper deficiency in individuals on long-term enteral nutrition (8).
