The mechanism of vitamin E enhancing immune function

1、 Protect immune cells from oxidative damage

Vitamin E, as a potent antioxidant, can eliminate free radicals and block lipid oxidation processes, protecting immune cells such as T lymphocytes and natural killer cells (NK cells) from oxidative stress damage and maintaining their normal function. For example, T cell membranes are rich in polyunsaturated fatty acids and highly sensitive to oxidative damage. Vitamin E stabilizes the cell membrane structure, ensuring the activity and proliferation ability of immune cells.

2、 Promote antibody production and immune molecule secretion

Vitamin E stimulates the proliferation and differentiation of B lymphocytes, promotes the synthesis of antibodies (such as immunoglobulins), and enhances humoral immune function. At the same time, it can also regulate the secretion of immune signaling molecules (such as cytokines), optimizing the immune system's recognition and clearance efficiency of pathogens.

3、 Regulating the intensity of immune response

Vitamin E maintains the dynamic balance of the immune system by balancing the ratio of Th1/Th2 cell subsets, avoiding an overly strong (such as excessive inflammatory response) or weak (such as immune suppression) immune response. This regulatory effect is of great significance for the prevention and treatment of chronic inflammatory diseases, such as autoimmune diseases.

4、 Synergistic anti-inflammatory effect and immune support

Vitamin E reduces the negative impact of inflammation on the immune system by inhibiting the production of pro-inflammatory mediators such as prostaglandins. For example, chronic inflammation can weaken immune cell function, while the anti-inflammatory properties of vitamin E can indirectly enhance immune defense efficiency.

5、 Synergistic enhancement with other nutrients

Vitamin E needs to work synergistically with antioxidant nutrients such as vitamin C and selenium to eliminate free radicals and repair oxidative damage, forming a more comprehensive immune protection network. For example, vitamin C can reduce oxidized vitamin E molecules and maintain their sustained antioxidant capacity
