Introduction

Copper is an essential trace mineral required for the formation of red blood cells, energy production, iron metabolism, nerve health, and immune function. Although needed in small amounts, copper plays a crucial role in many enzymatic processes.

What Is Copper?

Copper is a trace mineral that works closely with iron to form hemoglobin and supports multiple enzyme systems in the body.

• Type: Essential trace mineral
• Main role: Iron metabolism and enzyme activity
• Storage: Liver, brain, and muscles

How Copper Works in the Body

Copper acts as a cofactor for enzymes involved in energy production, antioxidant defense, and connective tissue formation.

• Helps form red blood cells
• Supports iron absorption and utilization
• Plays a role in nerve signal transmission
• Contributes to antioxidant defense systems

Sources of Copper

• Nuts and seeds (cashews, sunflower seeds)
• Whole grains
• Legumes
• Dark chocolate
• Shellfish
• Organ meats

Copper Deficiency

Copper deficiency is uncommon but may occur with malabsorption, excessive zinc intake, or certain genetic disorders.

Common deficiency symptoms include:

• Anemia
• Frequent infections
• Nerve damage or numbness
• Bone weakness
• Fatigue

Dosage & How to Take Copper

• Adults: 900 mcg/day
• Pregnancy: 1000 mcg/day
• Breastfeeding: 1300 mcg/day
• Upper limit: 10,000 mcg/day (10 mg)

Copper supplements should be taken only when needed and under guidance.

Forms of Copper

• Copper gluconate
• Copper sulfate
• Copper citrate
• Chelated copper

Benefits & Uses

• Supports red blood cell formation
• Enhances iron utilization
• Supports nerve and brain health
• Strengthens connective tissues
• Supports immune function

Safety, Side Effects & Precautions

• Excess intake may cause nausea or liver damage
• High zinc intake can reduce copper absorption
• Avoid unnecessary supplementation
• People with Wilson’s disease must avoid copper supplements

Special Populations

• People taking high-dose zinc: Monitor copper levels
• Elderly: Risk of imbalance with supplements
• People with anemia: Copper status may need evaluation
• Individuals with malabsorption: Higher deficiency risk
