Copper is used for treating copper deficiency, anemia due to copper deficiency, zinc-induced copper deficiency, improving wound healing, osteoarthritis, and osteoporosis. Copper is essential in increasing energy, forming connective tissue, and metabolizing iron. Copper is important in maintaining normal function of the brain and nervous system. Copper aids with neurotransmitter synthesis, break down of neurotransmitters, and formation of myelin. Copper also forms melanin-giving color to our hair, skin, and eyes, serves as an antioxidant, and regulates gene expression.
