Copper replacement for copper deficiency
Copper supplement
A supplement used to replace copper in people who are deficient, for example during long-term tube or drip feeding or with malabsorption.
What is Copper supplement?
A copper supplement is used to replace copper in people who do not have enough, which can happen during long-term tube or drip feeding, with some digestive conditions that stop nutrients being absorbed, or after certain surgery. Copper is needed for healthy blood cells, nerves and connective tissue, and a lack of it can cause anaemia, low white blood cells and nerve problems. It can be given by mouth or, where needed, added to drip feeding. It is generally well tolerated, but too much copper over time can affect the liver, so blood levels are usually checked. It is used under medical or dietitian supervision.
Education and reference only. This is a plain-language guide to Copper supplement — it deliberately contains no doses. Doses depend on the person, the brand and the reason for treatment, and belong with your prescriber. Always check the BNF, the product labelling (SmPC) and follow medical advice.
What it is
A copper supplement provides extra copper, a mineral the body needs in small amounts to make healthy red and white blood cells, keep nerves working, build connective tissue and run several important body processes. It is used when someone becomes copper deficient, which can happen with long-term tube feeding or feeding through a drip, with conditions that stop the gut absorbing nutrients, after some types of stomach or bowel surgery, or rarely with very high zinc intake that blocks copper absorption. Depending on the situation, copper can be given by mouth or added to feeds given into a vein, under the guidance of a doctor or dietitian.
How it works
Copper is an essential part of several enzymes the body uses to make blood cells, maintain nerves and blood vessels, and handle iron. When copper runs low, these processes start to fail, leading to problems such as anaemia, a fall in white blood cells and nerve symptoms. A copper supplement simply restores the body's copper to a healthy level so these enzymes can work normally again and the deficiency-related problems improve. Because the body needs only a small amount and stores it, the supplement is given to correct and then maintain a normal balance rather than in large excess.

Practical use
How to take Copper supplement
General, dose-free guidance — always follow your prescriber's and the leaflet's specific instructions.
- Take it exactly as advised by your doctor or dietitian, as the aim is to correct a genuine deficiency, not to take extra copper.
- If it is given by mouth, take it as directed, often with food if it upsets your stomach.
- If it is added to drip feeding, this is arranged and given by the healthcare team.
- Attend for the blood tests advised, as copper levels are checked to keep the dose right.
- Do not take copper supplements if you have Wilson's disease, a condition where copper already builds up.

Advantages & disadvantages of Copper supplement
Advantages
- Corrects copper deficiency and the problems it causes, such as anaemia, low white cells and nerve symptoms.
- Can be given by mouth or, where needed, added to feeding given into a vein.
- Generally well tolerated when used to restore a normal copper balance.
Disadvantages
- Too much copper over time can affect the liver and cause stomach upset.
- Needs blood tests to keep the level right, especially with long-term use.
- Not suitable for people with Wilson's disease, where copper already builds up.
Practical use
Good to know
The main thing to know is that copper supplements are for genuine copper deficiency, not a general tonic; copper is needed only in small amounts and the aim is to restore a normal balance. Deficiency is most likely in particular situations, such as long-term artificial feeding, malabsorption conditions, after certain surgery, or with very high zinc intake that blocks copper, so identifying the cause matters. It is generally well tolerated, but taking too much copper over a long time can affect the liver and cause stomach upset, which is why blood copper levels are usually checked to keep the dose right. People with Wilson's disease, an inherited condition in which copper already builds up, should not take copper supplements. It is best used under medical or dietitian supervision, especially when copper is added to drip feeding.
Who should not take it / use with caution
- People with Wilson's disease, an inherited condition where copper builds up, should not take copper supplements.
- People who have had a serious reaction to a copper preparation should not take it.
- It is used with care in people with liver problems, under medical guidance and monitoring.
Monitoring
- Blood tests to check copper levels and keep the dose right.
- Watching for improvement in deficiency problems such as anaemia and low white cells.
- Checking liver function with long-term use, as too much copper can affect the liver.
Side effects
- Stomach upset, nausea or a metallic taste, particularly with copper taken by mouth.
- With too much copper over time, effects on the liver, which monitoring is designed to catch.
- Rarely, other effects linked to excess copper, which is why levels are checked.
Key interactions
- High intake of zinc can block copper absorption, which can itself cause copper deficiency.
- Copper can affect how some other minerals and medicines behave, so tell your team what you take.
- Other supplements and tube or drip feeds need balancing so copper is neither too low nor too high.
Available as: Preparations taken by mouth, and copper added to feeding given into a vein.
