Copper: A Mineral Against Gray Hair
Copper (= Cuprum) (Cu)
For humans – a mineral against gray hair.
In the human body copper participates in the process of tissue respiration, in anabolic processes (synthesis of new structures and substances), synthesis of hemoglobin and other iron porphyrins, skin, hair, and eye pigments, and influences the functioning of endocrine glands.
The importance of copper for the human body has been known since ancient times. Thus, the ancient Greek physician and philosopher Empedocles wore copper sandals, believing that they provided him with mental agility and imagination. Avicenna in “The Canon of Medicine” (1020 AD) prescribed copper powder for bone fractures and recommended tying copper plates to purulent wounds. The Khanty and Nenets in the Tyumen region behave similarly, insisting on infusing water with metallic copper powder, which they drink for bone fractures. In Syria and Egypt, newborns are given copper bracelets to prevent rickets and epilepsy. For the same reason, Old Believers in the Urals and Siberia prefer to wear copper crosses on a string.
The daily requirement for copper in the human body is from 1 to 7 mg (according to the recommendations of the World Health Organization (WHO), the daily requirement for adults is 1.5 mg). Copper deficiency in the body can develop with insufficient intake of this element (1 mg/day or less).
Up to 95% of copper that enters the body is absorbed in the gastrointestinal tract (with the maximum amount in the stomach), then in the duodenum, jejunum, and ileum. The body absorbs divalent copper better. In the blood, copper binds with serum albumin (12–17%), amino acids histidine, threonine, glutamine (10–15%), transport protein transcuprein (12–14%), and ceruloplasmin (up to 60–65%).
Copper penetrates all cells, tissues, and organs. The highest concentration of copper is noted in the liver, kidneys, brain, and blood; however, copper can also be found in other organs and tissues.
The liver plays a leading role in copper metabolism, as it synthesizes the protein ceruloplasmin, which has enzymatic activity and participates in the regulation of copper homeostasis. Moreover, ceruloplasmin participates in the oxidation of divalent iron to trivalent iron, as only in this form is iron available to the body.

Biological role in the human body. Copper plays an important role in the processes of heme biosynthesis and, accordingly, hemoglobin. Therefore, its deficiency, like that of iron, can lead to anemia. Copper is part of the structure of cytochrome c oxidase – the terminal enzyme of the mitochondrial respiratory chain and, consequently, is necessary for energy generation processes in the cell. Copper plays an important role in the antioxidant protection of the body, as it, along with zinc, is part of the structure of the tissue antioxidant enzyme – superoxide dismutase and the antioxidant protein in blood plasma – ceruloplasmin, which is a carrier of this metal. Copper has anti-inflammatory and antiseptic properties (possibly due to its antioxidant action). It regulates the metabolism of catecholamines, serotonin, tyrosine, melanin, promotes increased insulin activity and more complete utilization of carbohydrates. It is necessary for growth and reproduction and is part of the melanin pigment.
This trace element participates in the formation of the structure of connective tissue proteins – collagen and elastin, which are structural components of bone and cartilage tissue, skin, lungs, and blood vessel walls. Therefore, copper deficiency can lead to the formation of aortic aneurysms and blood vessels in the brain. For the same reason, copper deficiency leads to demineralization of bone tissue and osteoporosis.
Copper participates in the formation of myelin sheaths of nerves, degeneration of which leads to multiple sclerosis and other severe disorders of the nervous system.

Synergists and antagonists of copper. Iron, zinc, ascorbic acid, tannins, antacids, and carbohydrates affect the bioavailability of copper if they are included in the diet in large quantities. To a greater or lesser extent, the level of copper in the diet can, in turn, affect the metabolism of some of these nutrients.
Copper deficiency alters iron metabolism, while excessive amounts of iron in the form of inorganic salts lead to symptoms of copper deficiency.
Depletion of copper reserves is observed in people who have taken large amounts of zinc and molybdenum for a long time.
There is a physiological antagonism of copper with molybdenum and sulfate sulfur, as well as with manganese, zinc, lead, strontium, cadmium, calcium, silver.
In turn, copper can inhibit the absorption of iron, cobalt, zinc, molybdenum, and vitamin A by the body. Oral contraceptives, hormonal agents, and corticosteroid preparations promote the increased excretion of copper from the body.
Daily addition of 1500 mg of ascorbic acid leads to a decrease in ceruloplasmin concentration, which is a copper carrier. The absorption of copper is not hindered by 600 mg of ascorbic acid, but there is a decrease in ceruloplasmin and, likely, its oxidase activity may be disrupted.
Experimental studies have shown that the type of carbohydrates consumed in the diet affects the degree and severity of copper deficiency. The effects of sucrose and fructose are particularly unfavorable.
Cobalt (in moderate physiological doses) increases copper absorption by the body.

Signs of copper deficiency. One of the early signs of copper deficiency is osteoporosis (copper plays a significant role in collagen formation – one of the main proteins that form bone tissue, skin, and connective tissue), graying and baldness.
Copper deficiency in the body can cause growth retardation, anemia, depigmentation of hair (graying) and partial baldness, general weakness, decreased respiratory function, the appearance of skin ulcers, loss of appetite, and consequently, weight loss, atrophy of the heart muscle, decreased hemoglobin and red blood cell counts.
Copper levels decrease in diabetes. Its content also decreases during emotional stress, psychasthenia, epilepsy, so it is possible to treat nervous and mental disorders with preparations and plants containing copper. In this regard, malachite products can be considered as means to calm the mental state, as malachite contains copper.

Copper levels increase in epilepsy, hepatitis, cirrhosis of the liver, anemias, leukemias, and various infectious diseases (scarlet fever, diphtheria, tuberculosis, meningitis).
There is a direct relationship between the level of copper in the blood and the increase in body temperature as a result of inflammation. In terms of diagnostic significance, an increase in copper content is comparable to determining the ESR.

Main manifestations of copper excess: functional disorders of the nervous system (memory impairment, depression, insomnia); allergic dermatoses, increased risk of atherosclerosis, liver and kidney dysfunction, hemolysis of red blood cells, the appearance of hemoglobin in urine, anemia, liver damage with the development of cirrhosis and secondary brain damage associated with hereditary copper and protein metabolism disorders (Wilson’s disease – a condition associated with copper accumulation in the liver and other tissues). Copper content in the liver increases in cirrhosis, very high levels are observed in primary biliary cirrhosis and atresia of the bile ducts. In these conditions, the appointment of chelating agents is more recommended than limiting copper in the diet.
Excessive copper intake by humans leads to excessive deposition of this element in brain tissue, skin, liver, pancreas, and myocardium.
