Vitamin E can also improve the immune level by acting with enzymes and peroxides on cyclooxygenase to reduce the synthesis rate of prostaglandin E2. Vitamin E regulates immunity by reducing the release of adrenocortical hormone. Resist stress. On the one hand, vitamin E can improve animal immunity by protecting cell membrane and organelle membrane from oxidative damage, maintaining the integrity and stability of cells and organelles, and ensuring the normal function of cells;
On the other hand, vitamin E can regulate the synthesis of cytokines, prostaglandins, coagulants and cell growth promoting factors. Vitamin E can enhance the activity of macrophages and promote the oxidative metabolism of neutrophils in the peripheral blood system.
