Zinc plays a crucial role in the body's immune function by facilitating the development and activation of immune cells, such as T cells and natural killer cells. It also helps in the production of cytokines, which are essential for cell signaling in immune responses. A deficiency in zinc can impair immune response, making the body more susceptible to infections. Furthermore, this mineral supports wound healing and may have antioxidant properties, highlighting its importance in overall health and recovery.
