Which vitamin helps support various cellular functions in the immune system?

Vitamin C plays a crucial role in supporting various cellular functions in the immune system. It is well-known for its antioxidant properties, which help protect immune cells from oxidative stress and damage. Additionally, vitamin C is essential for the growth and function of immune cells, such as lymphocytes, which are vital for the body’s defense against infections. It aids in the proliferation and differentiation of these immune cells, enhancing the body's overall immune response.

Vitamin C also assists in the production of collagen, which is important for the structural integrity of tissues, including those in the immune system. By promoting healthy skin and mucosal barriers, vitamin C helps create a physical defense against pathogens. Its role in bolstering immunity is supported by various studies showing that adequate levels of vitamin C can lead to a reduced incidence and duration of respiratory infections.

While other vitamins listed, like vitamin D and B6, also have important immune functions, vitamin C is particularly recognized for its direct involvement in enhancing immune cell functions. Folate, on the other hand, is more associated with DNA synthesis and cell division, which, while important for overall health, are not as directly linked to immune system activity as vitamin C.
