What Is Copper

Copper is an essential trace mineral that the body needs in small amounts for several important processes. It helps form connective tissues such as collagen, supports iron absorption and red blood cell formation, and plays a role in the immune system and in normal skin and hair pigmentation. Copper also works as part of antioxidant enzymes that protect cells from damage. Copper and Zinc compete for absorption, so long-term high-dose zinc supplements can lower copper levels; this is why well-designed multivitamins balance the two.

Key Benefits

• Supports the formation of collagen and connective tissue
• Contributes to normal iron transport and red blood cell formation
• Supports normal immune function
• Contributes to normal skin and hair pigmentation
• Forms part of antioxidant enzymes that protect cells
• Contributes to normal energy-yielding metabolism

Who Needs It

Anyone looking for a balanced mineral intake as part of a daily multivitamin, particularly people taking zinc supplements over the long term, since high zinc intake can reduce copper absorption. Many Nigerian foods are naturally rich in copper, so a balanced multivitamin is usually enough.

Copper in Nigerian Foods

Nigeria grows several of the richest copper foods in the world. Beniseed (sesame), which Nigeria exports in large quantities, and cashews from states like Kogi and Oyo are both high in copper, as are groundnuts. Periwinkle and other shellfish, common in dishes from Rivers and Cross River, are excellent sources, along with liver from assorted meat.

Recommended Dosage / Form

Typically included in small amounts in a daily multivitamin. Copper is needed only in trace amounts, so check your total intake before adding separate copper products.

Science / Research Note

Copper's roles in connective tissue formation, iron metabolism and antioxidant enzymes are well established in nutrition science. The interaction between copper and zinc absorption is also well documented.
