Copper was first utilized by man over 10,000 years ago. A copper pendant discovered in what is now northern Iraq has been dated about 8700 B.C. For nearly five millennia copper was the only metal known to man, and thus had all the metal applications.

Early copper artifacts, initially ornamental, then utilitarian, were undoubtedly worked out from “native copper,” pure copper discovered in conjunction with copper-bearing ores in a few locations all over the world. By 5000 BC, the dawn of metallurgy had arrived, as evidence exists of the smelting of simple copper oxide ores such as malachite and azurite.

Not until about 4000 BC did gold appear on the scene as male’s 2nd metal. By 3000 B.C., silver and lead were being used and the alloying of copper had actually started, initially with arsenic and then with tin. For lots of centuries, bronze reigned supreme, being used for rakes, tools of all kinds, weapons, armor, and ornamental things. Though copper came from the island of Cyprus-from whence its name-and many other sites in the Middle East, the origin of the tin in the bronze is still a secret.

The Bronze Age unexpectedly ended at about 1200 BC, with the general collapse of the ancient world and the disruption of global trade routes. The supply of tin in particular dried up and the Iron Age was introduced, not since iron was a remarkable material, but since it was commonly available. The purposeful alloying of iron with carbon to form the first steels did not take place for centuries.

Economy in using copper and its alloys was demanded by these early trade interruptions, and this efficiency in use and re-use has actually continued from that day to this. [2]

Function of Copper in the Human Body

Copper is an element vital to the homeostasis of the human body due to its role in energy production, iron metabolic process, neuropeptide activation, and connective tissue and neurotransmitter synthesis.

Copper-Related Conditions

Excessive or too little copper can be harmful to your body. There are lots of conditions related to copper levels suggesting that we must have sufficient amounts of copper in the body.

Copper absorption depends upon 4 primary aspects: 1) the absorption of copper from the gastrointestinal tract; 2) copper transportation in the portal blood; 3) the extraction of copper by hepatocytes from the portal blood supply; 4) copper uptake by the peripheral tissues and by the central nerve system.

Both adults and children can be prone to copper deficiency. For children, shortage can result in slowed development and advancement. For adults, there are numerous problems that can emerge consisting of anemia, heart and blood circulation problems, bone problems, and issues in the nervous and body immune system. Here are two well-known copper disorders you must know.

Wilson Illness

Wilson illness was first defined back in 1912 by Samuel Alexander Kinnier Wilson through his released work entitled “Progressive lenticular degeneration: a familial nervous disease associated with cirrhosis of the liver.” It is characterized by excess copper stored in various body tissues, particularly the liver, brain, and corneas of the eyes. If left untreated, it may trigger liver illness, central nerve system dysfunction, and death. Research studies have determined that it is brought on by disturbance or mutation of the ATP7B gene that plays a role in the movement of excess copper from the liver to be converted into bile and eventually be excreted from the body through the intestinal tracts. Dealing with Wilson illness is focused on decreasing copper levels to nontoxic levels.

Menkes Illness

According to World Health Organization, there are more health threats from absence of copper than from an excess of copper in the body. Menkes disease is caused by copper shortage. In particular, it is brought on by the anomaly of the ATP7A gene which is involved in the delivery of copper to the secreted copper enzymes and in the export of surplus copper in the cell. The mutation causes bad distribution of copper to your body’s cells leading to low levels of copper in the brain and other tissues. This illness is defined by sparse, kinky hair and degeneration of the nervous system. Patients likewise have actually decreased collagen formation. [4]

Health Advantages of Copper

Copper plays lots of crucial functions in preserving a healthy body and some of its benefits include:.


The health advantages of copper relate to its anti-inflammatory actions that assist in decreasing the signs of arthritis.

This likewise keeps your skin from looking older, by keeping it flexible and less prone to sagging and wrinkles.

Brain Stimulant

Copper is widely referred to as a brain stimulant, which is why foods rich in this component are frequently categorized as “Brain Foods”. Nevertheless, copper material in the diet plan needs to remain in adequate proportions, because excessive of it is likewise not healthy for the brain. It has a control function to play in the brain, so the quantity of copper supplementation needs to be stabilized. It has actually been associated straight with higher thought processes, especially in relation to the effect of its transporter protein, Atp7a. Research studies have actually shown a direct link in between its material within the brain and imaginative or out of the box thinking, showing that it enables neural pathways to develop in special ways.

Co-enzymatic Responses

Copper is either a component or a cofactor in as many as 50 various enzymes that take part in different biological reactions within the body. These enzymes can work properly only in the existence of it. Without the enzymatic reactions in our various organ systems, our entire metabolism would decrease and the elaborate network of reactions and metabolic pathways would stop to work in harmony. This is specifically crucial in particular brain paths, especially those including dopamine and galactose.

Absorption of Iron & Sugar

Copper helps in the absorption of iron from the intestinal system and in the release from its primary storage sites like the liver. It likewise assists in the usage of sugar in the body. By assisting in the absorption of iron from food and other extra sources, copper ensures a healthy red blood cell count and proper oxygenation of various organ systems. Without an appropriate supply of iron, individuals struggle with anemia, also called iron deficiency, which can be a very dangerous condition resulting in fatigue, muscle pains, digestion problems, and general weak point.

Avoids Premature Aging

Copper is a strong anti-oxidant, which works in the presence of the antioxidant enzyme superoxide dismutase to safeguard the cell membranes from totally free radicals. Superoxide dismutase is one of the strongest antioxidants that work within the body in the battle versus free radicals.

Studies have actually revealed that copper can decrease the levels of LDL (bad) cholesterol and help to increase useful HDL (excellent) cholesterol. This decreases the opportunities of cardiovascular diseases like atherosclerosis, heart attack, and stroke. [5]

Copper Shortage

What is copper shortage?

Copper is a natural element essential to many of the body’s day-to-day processes. Although discovered in the body in small amounts, copper is important to the proper functioning of the worried, musculoskeletal, and immune systems, as well as the production of red blood cells. A shortage, or an insufficient quantity of copper, can be due to a poor diet or malabsorption or an acquired disorder.

If your copper shortage is gotten, you might experience fatigue, paleness, frequent infections, neurologic deficits, and bone and cardiovascular issues. If you or your child’s copper shortage is acquired, you may observe unique facial features and kinky hair, a failure to prosper, weak muscles, seizures, and hypopigmentation.

Acquired copper deficiency can usually be corrected by supplements and a proper diet. However, results of acquired copper deficiency are often permanent.

You should visit your medical care physician to confirm the diagnosis and go over copper supplements.

Copper shortage symptoms

Signs vary and impact body systems in a different way depending upon whether your copper deficiency is gotten or acquired. Obtained copper deficiency in grownups leads to hematologic and immune-related signs, neurologic and sensory-related signs, and tissue-related signs.

Hematologic and immune-related signs

Hematologic, or relating to the blood, is related to copper since copper is essential to the body’s processing of iron. Iron is essential for red cell production. Hence, this can have widespread impacts, such as:.

Anemia: Low red blood cell counts lead to tiredness and paleness (pallor) that do not improve with iron supplements.

Regular infections: This is because of low leukocyte counts (neutropenia).

Neurologic and sensory-related signs

Copper plays an important function in the production and upkeep of myelin, a compound that coats nerves and facilitates the communication of signals throughout the nerve system (neurotransmission). A copper-containing enzyme also transforms the neurotransmitter dopamine to the neurotransmitter norepinephrine. Copper deficiency may result in:.

Peripheral neuropathy: Weak point, numbness and discomfort can be felt, normally in your hands and feet.

Myelopathy: Spine problems that can lead to lessening body function, pain, and weak point.

Incorrect synthesis of neurotransmitters: For example, insufficient dopamine might hinder feelings of satisfaction or understanding benefits.

Tissue-related symptoms

A copper-dependent enzyme mediates the linking of collagen and elastin, which enables the production of strong and versatile connective tissue. Copper shortage may lead to:.

Fragile bones: This is because of impaired bone calcification.

Cardiovascular problems: This consists of blood vessel weak point and heart abnormalities (cardiomyopathy).

Signs of acquired copper shortage.

Children with acquired copper shortage may have the following symptoms:.

” Kinky” hair: Hair appears sparse, steely, twisted, or kinky.

Failure to prosper: Kid may be challenging to feed and experience weight gain and development at less than anticipated rates.

Facial features: The face may appear pudgy with rosy cheeks and drooping skin.

Weak muscles (hypotonia): Low muscle tone can result in a “floppy” appearance.

Extreme intellectual disability and developmental hold-up: Copper is vital for brain advancement. Kids with Menkes illness may reach milestones (such as sitting and strolling) at later ages than normal and are typically cognitively impaired and might seem specifically irritable.

Seizures: Also due to abnormal brain development, kids may experience episodes of shaking, rigidness, and modified psychological status.

Hypopigmentation: Melanin, which plays a role in the color of hair, skin, and eyes, depends on a copper-containing enzyme.

Copper shortage causes

Obtained copper deficiency is typically triggered by a combination of diet, nutrient shortages, or insufficient intestinal environments that can be caused by disease or surgery. Acquired copper shortage is largely hereditary; information of its frequency are also explained in this section.

Dietary causes

Gotten copper shortage is likewise uncommon like the inherited type because our bodies require so little copper. Most people are able to meet their day-to-day needs through a normal diet plan. However, circumstances in which dietary copper shortage occurs include:

Protein shortage throughout childhood: Babies fed just cow’s milk formula might not get appropriate copper.

Excess Zinc: Zinc impairs the absorption of copper. Daily zinc consumption greater than 50 mg/day for a prolonged period of time can result in copper deficiency.

Consistent baby diarrhea: Infants with consistent diarrhea may not soak up appropriate necessary nutrients.

Overall parenteral nutrition (TPN): Some individuals with serious disease have a failure to eat by mouth and take in nutrients through the gut. Rather, they may be prescribed nutrition through intravenous solutions. However, sometimes the TPN formula does not contain appropriate copper, so people can become copper lacking if they depend on the formula for a prolonged amount of time.

Gastrointestinal Disease

Specific gastrointestinal illness affect the ability of the gut to soak up essential nutrients, consisting of copper. This includes:

Celiac illness: An illness in which the lining of the gut ends up being swollen by gluten.

Cystic fibrosis: A genetic disease that impacts the lungs and intestinal systems.

Brief gut syndrome: This happens after surgical removal of intestinal tracts for severe youth disease.

Surgical treatment

Nutrient deficiencies, such as vitamin B12, are likewise typically present. These can be exacerbated by surgeries such as:

Bariatric surgery: Weight-loss surgeries such as gastric banding or gastrectomy can disrupt the absorption of nutrients.

Other stomach surgery: This consists of different surgical treatments such as those for cancer, which can likewise hinder absorption.

Treatment choices and prevention for copper shortage

In some cases, such as Menkes disease, damage that happened due to copper shortage is largely irreparable. Nevertheless, success has actually been discovered in preventing neurological deficits if treatment is initiated prior to two months of age. In obtained cases, such as neuropathy or anemia secondary to copper deficiency, copper supplementation has been associated with improvement in symptoms and lifestyle. [6]

Recommended Consumption

The Recommended Dietary Allowance (RDA) for copper:.

  • Children 0.3– 0.9 mg/day (depending upon age)
  • Grownups 0.9 mg/day
  • Pregnancy and lactation 1– 1.3 mg/day

The typical intake of copper from food in the United States is around 1.0 to 1.6 mg/day for adult men and women. [7]

Possible Adverse Effects

In typical amounts, copper is not related to any risks or negative effects. But just like many vitamins and minerals, having excessive copper in your system can be harmful.

Copper toxicity is uncommon, though it can occur if you consume too much copper day after day for a long period of time. Copper toxicity can also happen in individuals with Wilson’s disease, an inherited disorder that triggers copper to develop in the liver, brain, and other organs.

Some signs of copper toxicity consist of:.

  • Stomach pains
  • Nausea, throwing up, diarrhea
  • Headache
  • Dizziness
  • Weakness
  • Metallic taste in the mouth

More serious signs of copper toxicity may include:.

  • Cirrhosis
  • Jaundice
  • Heart problems
  • Red blood cell irregularities

Anyone thinking about a copper supplement must first contact a healthcare provider. [8]
