• Collagen Formation: Copper activates lysyl oxidase, an enzyme necessary for cross-linking collagen and elastin, both of which are important for connective tissue strength, skin elasticity, and overall structural integrity.

• Iron Metabolism: Copper assists in converting ferrous iron into ferric iron, a necessary step for incorporating iron into hemoglobin, the protein responsible for oxygen transport in red blood cells.

• Immune Function: Copper’s role in the development and maintenance of immune cells reflects its importance in supporting a healthy response to infections and inflammation.

• Neurotransmitter Synthesis: The mineral is involved in the production of catecholamines, neurotransmitters that play roles in mood regulation, stress response, and overall brain function.

Effects of Deficiency

A lack of copper in the diet can have significant effects on the body. When copper levels drop below adequate levels, several systems may begin to falter, leading to a range of health issues:

• Anemia: Copper deficiency can interfere with iron metabolism, resulting in decreased hemoglobin synthesis and anemia.

• Neurological Problems: Copper is essential for the maintenance of nerve cells, and its deficiency has been linked to neuronal degeneration and impaired cognitive function.

• Immune System Impairment: Reduced copper levels may weaken the immune response, increasing susceptibility to infections.

• Osteoporosis and Connective Tissue Disorders: Copper deficiency can lead to decreased collagen formation, impacting bone strength and potentially contributing to osteoporosis and other connective tissue issues.

• Cardiovascular Problems: A deficiency in copper may also negatively affect cardiovascular health, as copper is involved in maintaining the elasticity and integrity of blood vessels.

Dietary Sources

Getting enough copper through your diet is essential for reaping its health benefits. Copper is found in a variety of foods, making it relatively easy to incorporate into most balanced diets. A diverse intake of foods usually meets the body’s daily copper requirements, although supplementation may be considered in specific cases, particularly where medical conditions or restrictive diets are concerned.

Best Food Sources

Incorporating foods that are rich in copper into your diet can be both enjoyable and healthful. Consider integrating the following sources:
