The immunity in our bodies comes from very special and diverse cells in the blood. With respect to cell-mediated immunity, retinol is important in the activation of T cells (73), and vitamin A deficiency may affect cell-mediated immunity by decreasing the number or distribution of T cells, altering cytokine production, or by decreasing the expression of cell-surface receptors that mediate T-cell signaling (56). Vitamin C helps NK cells track and destroy tumor cells as well by reducing the shielding effect of platelets (blood clotting cell fragments) that would prevent NK cells from destroying them. Vitamin C is also an essential part of your skin’s defense system, where its antioxidant properties enable it to help strengthen your skin’s natural barriers against environmental damage.
