Vitamin E:
Vitamin E is another essential vitamin needed for a healthy immune system by the body. Vitamin E increases the cell division in immune cells and also speeds up the IL-2 producing capacity of the T cells, thus increasing the capability of T cells to form a productive immune synapse. Vitamin E also helps in reversing the age-related defect during the phosphorylation in T cells. Vitamin E acts as a potent antioxidant that boosts the immune system to fight infections by avoiding the formation of blood clots in blood vessels.
