Which trace mineral is associated with the immune system and wound healing?

Zinc is a trace mineral that plays a vital role in supporting the immune system and facilitating wound healing. This mineral is essential for the proper functioning of immune cells, such as neutrophils and macrophages, which are crucial for mounting an effective immune response. A deficiency in zinc can lead to impaired immune function, making the body more susceptible to infections.

Additionally, zinc is necessary for the synthesis of proteins and DNA, both of which are critical during the tissue repair process. It helps in the regeneration of skin cells and promotes the healing of wounds by contributing to the formation of collagen, a key structural protein in the skin. This is why zinc is often recommended in clinical settings for patients with wounds or those recovering from surgery, as it enhances healing and reduces the risk of complications.

Far less involved in these processes are the other trace minerals listed. While iron is crucial for oxygen transport in the blood, iodine is primarily related to thyroid function, and copper plays various roles in overall metabolism and iron utilization but is not as directly linked to immune function and wound healing as zinc is.
