Copper is an essential trace mineral involved in a wide range of biological processes, including energy metabolism, iron absorption, and the formation of collagen and connective tissue. Research suggests that copper plays a key role in supporting antioxidant defenses, particularly through its involvement with the enzyme superoxide dismutase, which helps protect cells from oxidative stress. Studies indicate that adequate copper intake is also important for healthy immune function, bone mineralization, and the maintenance of nerve tissue. Commonly available in supplemental forms such as copper gluconate, copper sulfate, and copper bisglycinate, this mineral is found naturally in foods like shellfish, nuts, seeds, and organ meats. While copper is needed in only small amounts, ongoing research continues to explore its contributions to overall health and metabolic balance.
