The Trace Mineral for Energy & Immunity
Copper is an essential trace element that your body needs in small amounts for vital functions including energy production, nervous system health, immune function, and the formation of red blood cells. Your body carefully regulates copper levels, absorbing it from foods like shellfish, nuts, seeds, and whole grains, and storing it primarily in your liver. Blood copper testing measures the amount of copper circulating in your bloodstream, helping doctors detect both copper deficiency and rare copper overload conditions that can affect your health.
Think of copper as one of your body's essential elements—too little can cause significant health problems like anaemia and nerve damage, whilst too much can accumulate in organs and cause complications. Most people maintain healthy copper levels through a normal diet, but certain medical conditions, genetic disorders, or supplementation can disrupt this balance.

When Copper Levels Fall Out of Balance
Normal copper levels for adults typically range from 11-25 μmol/L, with slightly different ranges for infants and young children. When your copper levels are within this healthy range, it indicates that your body is successfully absorbing and regulating this essential mineral, supporting normal red blood cell production, nervous system function, and immune health.
Low copper levels indicate copper deficiency, a condition that can develop gradually and cause various health problems. Copper deficiency may present with anaemia unresponsive to iron treatment, neutropenia (low white blood cell counts), and osteoporosis. You might experience fatigue, weakness, frequent infections due to impaired immune function, and in more severe cases, neurological symptoms including numbness, tingling, and difficulty walking.
The neurological symptoms of copper deficiency can include numbness, tingling, muscle weakness, and problems with coordination. These neurological effects can become irreversible if copper deficiency isn't identified and treated.
High copper levels are less common than deficiency but can indicate serious conditions. The classical presentation of Wilson's disease includes progressive neurological symptoms, raised urinary copper excretion, and characteristic copper deposits in the corneas called Kayser-Fleischer rings.
Wilson's disease is a rare inherited disorder with an estimated prevalence of between 1:100,000 and 1:300,000. It leads to the accumulation of copper in organs and tissues, initially in the liver and then progressively in the kidneys, eyes, brain and other tissues. Onset of symptoms can occur at any time, but the peak is in adolescence, with the majority of patients presenting between the ages of 5 and 35 years old.

What Influences Your Copper Levels
Several factors can significantly affect your blood copper levels, with some causing deficiency and others potentially leading to excess.
Dietary intake provides the foundation for healthy copper levels. Good food sources include shellfish, organ meats, nuts, seeds, whole grains, and legumes. However, even with adequate dietary copper, absorption problems can lead to deficiency.
Risk factors for nutritional copper deficiency include intestinal issues, malabsorption in the gastrointestinal tract, and excessive zinc supplementation. Conditions like coeliac disease, inflammatory bowel disease, or previous stomach surgery can all impair copper absorption.
Excessive zinc intake, particularly from overusing zinc supplements can cause copper deficiency by competing with copper absorption in the intestines. This has become increasingly recognised as people take high-dose zinc supplements for various health concerns.
Genetic factors play a crucial role in rare copper metabolism disorders. Wilson's disease results from failure of copper secretion, causing copper to accumulate in the body. Menkes disease, another rare genetic condition, affects copper transport towards excessive secretion, leading to severe copper deficiency despite normal dietary intake.

How to Support Healthy Copper Levels
Managing copper levels depends on whether you have deficiency or excess, and addressing the underlying cause is crucial.
For copper deficiency, the first step is identifying why levels are low. If malabsorption is the cause, treating the underlying gastrointestinal condition becomes important. Your doctor might recommend copper supplementation, typically starting with oral supplements.
Dietary improvements can help support healthy copper levels. Including copper-rich foods like shellfish, nuts (particularly cashews and almonds), seeds, beans, and whole grains in your diet provides natural sources of this essential mineral. However, dietary changes alone may not be sufficient if you have significant malabsorption issues.
For Wilson's disease and copper excess conditions, treatment focuses on reducing copper absorption and increasing copper elimination. This typically involves medications that bind copper and help remove it from the body, along with dietary modifications to limit copper intake.

Understanding Your Copper Results
Normal Copper levels: 11-25 μmol/L
Low copper levels (below 11 μmol/L in adults) suggest copper deficiency, which warrants investigation into potential causes. Your doctor will likely assess your diet, medication use, and any gastrointestinal conditions that might affect absorption.
High copper levels (above 25 μmol/L) may indicate various conditions, though interpretation requires caution. Elevated levels can occur with inflammation, pregnancy, or oral contraceptive use.
For investigation of possible Wilson's disease, the recommended tests are caeruloplasmin and 24-hour urine copper rather than plasma copper levels alone. This is because Wilson's disease can paradoxically show low or normal blood copper levels despite copper accumulation in tissues.
Your doctor may order additional tests alongside copper measurement, including caeruloplasmin (the copper transport protein), zinc levels, liver function tests, or genetic testing if a hereditary copper disorder is suspected. The combination of results provides a more complete picture of your copper status and helps guide diagnosis and treatment.

The Takeaway
Copper testing provides valuable information about this essential trace element, helping identify both deficiency states that can cause anaemia and neurological problems, and rare genetic conditions where copper accumulates in organs.
Maintaining healthy copper levels is usually straightforward through a balanced diet, but certain conditions and supplementation practices can disrupt this balance. If your copper levels are significantly abnormal, working with your healthcare team to identify and address the underlying cause is essential.
