Copper
Copper is an essential trace mineral vital for numerous bodily functions. This reddish-brown metal plays a crucial role in forming red blood cells, maintaining nerve cells, and supporting the immune system. Copper is integral to the production of collagen, a protein essential for bone and tissue health. It also aids in energy production, iron absorption, and acts as a powerful antioxidant, protecting cells from damage. Research has shown that copper is necessary for proper brain development and function, making it a key nutrient for overall health and well-being.
Key Facts
- Copper is found in all body tissues and is particularly concentrated in the liver, brain, heart, and kidneys.
- It works synergistically with iron to produce red blood cells and haemoglobin.
- Copper is a component of many enzymes, including those involved in energy production and antioxidant defence.
- The body's ability to absorb copper increases when dietary intake is low and decreases when copper levels are sufficient.
- Excessive copper intake can lead to toxicity, causing symptoms such as nausea, vomiting, and liver damage.
- Copper deficiency, while rare, can result in anaemia, osteoporosis, and neurological problems.
What does the research say about copper and its function in the body?
