Copper is an essential mineral that humans need to survive. Copper is vital for bone strength, heart health, immune health, and skin health. It also helps to form red blood cells and maintain healthy blood vessels and nerves. While copper deficiency is rare, it can lead to serious health issues such as neutropenia (low levels of white blood cells), vision loss, and premature greying of hair. Copper supplements are available, but it is recommended to obtain copper through food sources such as oysters, sunflower seeds, and dark chocolate. A balanced diet typically provides sufficient copper intake, and excessive supplementation can lead to copper toxicity, a type of metal poisoning. Therefore, it is important to consult a healthcare professional before taking copper supplements.

What You'll Learn
Copper deficiency is rare
Copper is an essential mineral for the body. It helps maintain healthy bones, blood vessels, nerves, and immune function, and it contributes to iron absorption. However, copper deficiency is rare, and many foods contain a good amount of copper. The recommended daily intake of copper is 0.9 mg, and most people exceed this amount in their diets. Copper is commonly found in staple foods such as whole grain cereals, legumes, oysters, organ meats (especially liver), fruits, leafy green vegetables, nuts, and soybeans.
Copper deficiency can occur in people who have had gastrointestinal surgery, such as gastric bypass surgery, due to malabsorption of copper. It can also be caused by zinc intoxication, as zinc and copper compete for absorption in the stomach. Other causes of copper deficiency include celiac disease, inflammatory bowel disease, and Menkes disease, a rare genetic disorder.
The symptoms of copper deficiency can include fatigue, decreased red blood cells, early greying of the hair, and neurological problems such as numbness, tingling, and muscle weakness. However, copper deficiency is often misdiagnosed or underdiagnosed because its symptoms are similar to those of other conditions, such as vitamin B12 deficiency.
If you are concerned about your copper levels, it is recommended to speak with your doctor. They can evaluate your symptoms and risk factors and may order a blood test to determine your copper levels. Treatment for copper deficiency typically involves oral copper supplementation or intravenous copper. However, simply consuming a balanced diet with a variety of copper-rich foods should help you meet your daily copper needs.

Copper toxicity is dangerous
Copper is an essential mineral that supports various bodily functions, such as enzyme production and neurological functions. However, copper toxicity can occur when one is exposed to high levels of copper in water, food, or the air. While copper deficiency can have adverse health effects, an excess of copper in the body can be equally harmful.
Copper toxicity can result from ingesting large amounts of copper salts through the skin or consuming contaminated food and water. It can also be inherited, as in the case of Wilson's disease. The symptoms of copper toxicity include abdominal pain, nausea, vomiting, diarrhoea, headaches, and in severe cases, kidney failure. It can also lead to chest pain, chills, coughing, fever, general weakness, and lung inflammation, which can cause permanent scarring and decreased lung function.
In addition to the physical symptoms, copper toxicity can also affect mental health. High levels of copper in the body can build up in the brain, leading to potential neurological issues. Left untreated, copper toxicity can have severe health consequences and even result in death.
If you suspect copper toxicity, it is important to seek immediate medical attention. Doctors can treat copper toxicity with medications such as penicillamine or dimercaprol, or through chelation and hemodialysis. It is also recommended to contact your local water supplier if you believe your tap water has higher than normal copper levels.

Copper supports bone health
Copper is an essential mineral for the human body and supports bone health in several ways. Firstly, copper helps to maintain collagen and elastin, which are major structural components of our bodies. Collagen is the scaffolding for bone, and without sufficient copper, the body cannot replace damaged connective tissue or collagen, leading to joint dysfunction and other issues as bodily tissues break down. Copper may also have antioxidant properties, and along with other antioxidants, it may help prevent skin ageing.
Secondly, copper is necessary for proper bone development, and a deficiency may cause osteoporosis. Copper ions released from biological materials can affect osteoblasts and osteoclasts, either directly or indirectly, by modulating the inflammatory response, oxidative stress, and rapamycin signalling. Abnormalities in copper metabolism can lead to bone defects by directly impacting the viability of osteoblasts and osteoblasts and their bone remodelling function or by indirectly regulating bone metabolism by influencing enzyme activities as cofactors.
Some research has been conducted on the link between copper and bone health. One study found that out of a total of 728 menopausal, osteoporotic, or healthy women, those who received both calcium and micronutrient supplements, including copper, maintained lumbar bone mineral density with a significant difference compared to the group that only received a placebo. Another study of 11 healthy men found that when they were given several levels of copper intakes, an increase in some bone resorption markers was assessed when transitioning from medium to low copper intake, while these markers significantly decreased when transitioning from deficient to rich copper diets.
However, it is important to note that copper deficiency is rare in developed countries, and most people can meet their copper requirements through food sources such as dark chocolate, potatoes, shiitake mushrooms, cashews, crab, and sunflower seeds. Copper supplements are available, but it is recommended to first try to obtain essential vitamins and minerals through food to reduce the risk of an imbalance. Anyone considering copper supplements should first consult a doctor or healthcare provider.

Copper is essential for human life
Secondly, copper is important for heart health. Studies have shown that copper deficiency may be a leading cause of ischaemic heart disease and cardiovascular disease. Copper supplements have been suggested as a possible treatment for some patients with heart failure.
Thirdly, copper is necessary for a healthy immune system. Copper deficiency can cause neutropenia, or low levels of white blood cells, which leaves the body vulnerable to infections. Copper also supports the nervous system, with copper deficiency potentially leading to vision loss.
Finally, copper is beneficial for the skin. The skin needs copper to repair itself and stay healthy, and copper deficiency can lead to hypopigmentation or lightened skin colour. Copper may also have antioxidant properties, and together with other antioxidants, it may help prevent skin ageing.
Copper is a mineral that occurs naturally in the earth's soil, and while it is essential, humans only need to consume a small amount daily. Copper is found in many foods, including oysters, sunflower seeds, and dark chocolate, so most people can obtain sufficient copper through a balanced diet without needing supplements. However, copper supplements are available and can be beneficial in cases of diagnosed copper deficiency or for specific medical conditions.

Copper supplements are not always necessary
Copper is a mineral that occurs naturally in the earth's soil, and humans need it to survive. Copper is an essential nutrient for the body. It helps maintain healthy bones, blood vessels, nerves, and immune function, and it contributes to iron absorption.
However, copper supplements are not always necessary. Copper deficiency is rare, and most people consume adequate amounts of copper in their diet. Copper is found in many foods, so most people don't need a supplement. Foods that contain copper include oysters, sunflower seeds, and dark chocolate. Simply consuming a balanced diet should help meet your daily copper needs.
Additionally, the nutrients in food work together to create an effect that is more significant than that achieved by taking individual nutrients in isolation. Copper supplements can also interact with certain medications and products, leading to an imbalance in copper levels in the blood.
It is important to note that anyone considering taking a copper supplement should first speak to a doctor or healthcare provider. Copper supplements can be harmful if taken in excess, and they are not monitored by the Food and Drug Administration (FDA) for quality or purity. In conclusion, while copper is essential for human health, copper supplements are not usually necessary, and it is best to obtain copper through a balanced diet.
