Vitamin C (also called ascorbic acid, AA), an essential micronutrient for humans [1]. It’s deficiency is linked to impaired immunity [2], thereby, increases the risk of infection [3]. It acts against oxidative stress due to its strong antioxidant capacity. As a cofactor this vitamin helps in the biosynthesis and gene regulation of various enzymes [1]. It imparts immune defense through innate and adaptive immune responses [2]. It strengthens epithelial barrier function, thereby, resists the pathogenic invasion in our body [3]. The phagocytic cells (e.g. neutrophils) accumulate this vitamin, results in anti-microbial activity [1]. It is also needed for apoptosis and clearance of the spent neutrophils from sites of infection by macrophages, thereby decreasing necrosis/NETosis and potential tissue damage [4]. Moreover, it has many important roles in our skin health [5]. It enhances the differentiation and proliferation of lymphocytes (e.g., B and T cells) [6]. AA can be used to prevent and/or treat both local and systemic infections [3,7]. Therefore, adequate dietary intake of this vitamin is required for proper functioning of cells and tissues in our body [1].
