Vitamin C plays a crucial role in the immune system by supporting various cellular functions. It enhances the production of white blood cells and acts as an antioxidant, protecting immune cells from damage. Moreover, Vitamin C aids in the synthesis of collagen, which is essential for maintaining healthy skin and mucosal barriers, aiding in the body’s defense against pathogens. It also promotes the absorption of iron from plant-based foods, which is vital for overall health. A deficiency in Vitamin C can lead to a weakened immune response, increasing susceptibility to infections.
