Zinc plays a vital role in supporting immune health by functioning as a necessary trace element for immune cell development and function. It is crucial for the proper functioning of various immune system components, including T cells and macrophages, which defend against infections. Adequate zinc levels ensure optimal responses to pathogens and can reduce the duration and severity of illnesses. Moreover, zinc contributes to the healing process and helps maintain the integrity of the skin barrier. Ensuring sufficient zinc through diet or supplementation can help bolster overall immune function, especially in populations at higher risk for deficiencies.
