Recently, my boyfriend hasn't been feeling very well. I heard that vitamin C can boost the immune system, so I'd like to ask—can vitamin C really enhance immunity?

VC is the abbreviation for vitamin C, an extremely important antioxidant that activates immune cells by oxidizing cell membranes, thereby helping to enhance immunity. Research has shown that the greater the intake of VC, the better the body's antioxidant capacity. VC can alleviate many immune system disorders, such as chronic bacterial infections, diabetes, hypertension, hepatitis B, and senile dementia. VC also helps maintain antibody levels to defend against viral and bacterial invasions. Furthermore, VC aids in recruiting white blood cells and promotes their phagocytosis and destruction of parasites, thus enhancing immune function. Therefore, adequate intake of VC can help improve immunity.
