What are the side effects of vitamin E

Vitamin E is a natural antioxidant that is relatively easy to dissolve in fat and ethanol. It can be used in many ways in life, such as treating menopausal syndrome, beautifying the skin, and preventing miscarriage. So what are its side effects?

Long-term use of large doses of vitamin E can cause various diseases. The more serious ones include: thrombophlebitis or pulmonary embolism, or both, which is due to the fact that large doses of vitamin E can cause platelet aggregation and formation; increased blood pressure, which can be reduced or returned to normal after stopping the drug; breast enlargement in both men and women; headache, dizziness, vertigo, blurred vision, muscle weakness;

Skin cracks, cheilitis, angular cheilitis, urticaria; significantly aggravated symptoms of diabetes or angina pectoris; hormone metabolism disorders, decreased prothrombin; increased blood cholesterol and triglyceride levels; increased platelet count and activity, and decreased immune function.

Long-term and excessive consumption can cause adverse reactions such as blurred vision, breast enlargement, diarrhea, and dizziness. The human body's fat tissue can store a large amount of vitamin E, which is said to be enough for the body to consume for up to 4 years. Therefore, only a small amount of vitamin E needs to be supplemented. On the contrary, large amounts of accumulation in the body will cause adverse reactions.

Taking more than 300 mg of vitamin E daily can reduce the body's immune function and impair the function of the body's T lymphocytes, B cells and mononuclear phagocyte system, making it more susceptible to various diseases. The Netherlands conducted a two-year survey in which researchers divided more than 600 healthy elderly people over the age of 60 into two groups. One group took vitamin E, and the other group took placebos or sugar pills. During the study period, the incidence rates of respiratory infections in the two groups of elderly people were 68% and 67% respectively. Among them, the elderly who took vitamin E were ill for about 19 days, with fever accounting for 37%, and more and more severe symptoms of infection. The elderly who took placebo or sugar pills suffered from illness for about 14 days, with fever accounting for 25%. This shows that elderly people who take vitamin E are more likely to develop fever, have a longer and more severe course of illness when they suffer from respiratory infections.

Taking more than 400 mg of vitamin E daily can cause headaches, dizziness, nausea, blurred vision, excessive menstruation or amenorrhea, and even thrombophlebitis and pulmonary embolism due to platelet aggregation. This is especially important for the elderly, because pulmonary embolism can cause edema and atelectasis in the area near the embolism, affecting the diffusion function and reducing the arterial oxygen partial pressure. This is especially important for the elderly who have cor pulmonale or abnormal pulmonary vascular resistance before the embolism. A small amount of embolism can cause pulmonary hypertension, followed by complications such as heart failure.
