Zinc plays a vital role in the immune system by supporting various cellular functions, including the development and activation of T-cells, which are crucial for fighting infections. It acts as a co-factor for numerous enzymatic reactions, contributing to the growth and development of immune cells. Adequate zinc levels help maintain a healthy immune response and promote wound healing. Deficiency in zinc can lead to impaired immune function, increasing susceptibility to infections. Therefore, ensuring sufficient zinc intake is important for overall health and immune support.
