Abstract
Vitamin C is an important micronutrient for humans with pleiotropic function associated with its ability to donate electrons. It is a potent antioxidant and a cofactor for a family of biosynthetic and gene regulatory enzymes. Vitamin C contributes to immune system defense by supporting various cellular functions of both the innate and adaptive immune system. Vitamin C supports epithelial barrier function against environmental oxidative stress. Vitamin C accumulates in phagocytic cells like neutrophils, and may enhance chemotaxis, phagocytosis, generation of reactive oxygen species and ultimately microbial killing. It is also needed for apoptosis and clearance of the spent neutrophils from sites of infection by macrophages. Vitamin C deficiency leads to impaired immunity and better susceptibility to infections. In turn infections significantly impact on Vitamin C levels thanks to enhanced inflammation and metabolic requirements. In contrast treatment of established infections requires a significantly higher dose of vitamin to catch up on the increased inflammatory response and metabolic demand.one of the most reasons people take vitamin c supplements is to spice up their immunity as vitamin C is involved in many parts of the immune system. First, vitamin c helps encourage the assembly of white blood cells known as lymphocytes and phagocytes which helps to protect the body against various infections. Vitamin C is a strong antioxidant that can boost blood antioxidant levels and vitamin c rich foods and supplements have been linked to reduce blood uric acid levels. Many studies show vitamin c intake lower risk of several cancers and also reduced risks of eye diseases . Vitamin Cis an essential nutrient for healthy immune function. The main aim of the paper is to know the role of Vitamin C in immune function of the human body.
Vitamin C plays a crucial role in immune system defense, supporting various cellular functions and reducing the risk of various cancers and eye diseases.
