Which vitamin is often associated with boosting the immune system?

Vitamin C is well-known for its role in supporting and boosting the immune system. This vitamin contributes to the immune response by promoting the production and function of white blood cells, which are crucial in defending the body against infections and diseases. It helps to enhance the activity of immune cells, such as phagocytes and lymphocytes, and is also involved in the synthesis of antibodies that attack pathogens.

Additionally, vitamin C acts as a powerful antioxidant, protecting cells from damage caused by free radicals. This is particularly important during periods of illness or stress when the immune system is more vulnerable. The water-soluble nature of vitamin C means that regular intake through diet or supplements is necessary to maintain adequate levels, especially since the body cannot store it.

Although vitamins A, E, and B6 also play important roles in the immune system, vitamin C is specifically highlighted and widely recognized for its direct impact on enhancing immune function. Therefore, among the options presented, vitamin C stands out for its stronger association with boosting the immune system.
