About Copper

Micronutrient

Copper is a trace mineral essential for iron metabolism (it is required to incorporate iron into haemoglobin), antioxidant defence (as part of superoxide dismutase), connective tissue formation, and energy production. It also plays a role in neurological function and melanin production. Nuts (especially cashews), seeds, dark chocolate, legumes, wholegrains, and shiitake mushrooms are excellent plant sources.

⚠️ Too little

Rare from diet alone. Symptoms mirror iron-deficiency anaemia (which copper deficiency can cause), as well as neutropenia (low white blood cells), bone demineralisation, and neurological problems. Can be induced by excess zinc supplementation.

🚫 Too much

Copper toxicity from food is rare. Excess from supplements or contaminated water causes nausea, vomiting, liver damage, and in severe cases Wilson's disease-like symptoms. The tolerable upper limit is 5 mg/day for adults.
