What is an important function of zinc in the body?

Zinc plays a crucial role in supporting the immune system. It is essential for the development and function of immune cells, including T lymphocytes and natural killer cells, which are key players in the body's defense against pathogens. Additionally, zinc acts as an antioxidant, helping to combat oxidative stress that can impair immune function. A deficiency in zinc can lead to a weakened immune response, making the body more susceptible to infections. This highlights the importance of zinc in maintaining overall immune health and functionality.
