Copper is often thought of as something that has to do with electronics and wiring. However, it is also an essential mineral that we intake from various foods like avocados, shellfish, and potatoes amongst others. An average person (adolescent and adult) needs around 900 micrograms (mcg) a day. Notably, the upper limit for adults aged 19 years and above is 10 milligrams (mg) a day. Importance of Copper In BodyCardiovascular HealthLow levels of copper have been associated with elevated cholesterol and high blood pressure. Some researchers suggest that individuals with heart failure might benefit from copper supplementation. Animal studies have linked copper deficiency to cardiovascular disease (CVD). Neuron SignalingIn 2016, Professor Chris Chang, a chemist from the US, developed a fluorescent probe to monitor copper movement within nerve cells. He noted that "copper acts like a brake or dimmer switch for each nerve cell." His research indicated that excess copper can hinder neuron signaling, while lower levels restore it.Immune FunctionInsufficient copper can result in neutropenia, a condition marked by a deficiency of neutrophils, the white blood cells that combat infections. Individuals with low neutrophil counts are more susceptible to infectious diseases.OsteoporosisSevere copper deficiency is linked to decreased bone mineral density and an increased risk of osteoporosis. Further research is necessary to explore how even marginal copper deficiency might impact bone health.Collagen ProductionCopper is essential for the maintenance of collagen and elastin, two critical structural components of the body. Some scientists propose that copper may have antioxidant properties, which, along with other antioxidants, could help prevent skin ageing. Without adequate copper, the body struggles to repair damaged connective tissues and the collagen framework of bones, leading to various issues, including joint dysfunction.ArthritisAnimal studies suggest that copper may help prevent or delay arthritis, which is why some people wear copper bracelets for relief. Antioxidant ActionCopper may also function as an antioxidant, potentially reducing the production of free radicals. These free radicals can harm cells and DNA, contributing to cancer and other diseases.How To Get Copper In Your Body? Copper is found in a variety of food sources. The list encompasses shellfish, whole grains, beans, potatoes, yeast, dark leafy greens, cocoa, dried fruits, black pepper, organ meats like kidney or liver, and nuts such as cashews and almonds. In addition, certain fortified foods also contain a good amount of this nutrient. However, if a person is unable to get an adequate amount of this element, then it is advisable for that person to take supplements for the elements. Most multivitamin supplements contain 2 mgTrusted Source of copper.
