Taking vitamin E capsules can cure some women who suffer from bleeding or menorrhagia after placing intrauterine devices. The method is: take vitamin E 100 mg orally every other day, 7 days for 1 course of treatment, and general treatment for 1 to 3 courses of treatment.

3. Taking more than E300 mg of vitamin E every day will reduce the immune function of the body, and the functions of T lymphocytes, B cells and mononuclear phagocytes in the body are low, which is prone to various diseases. In a two-year survey conducted in the Netherlands, researchers divided more than 600 health of the elderly over the age of 60 into two groups, one taking vitamin E and the other taking placebo or sugar pills. During the study period, the incidence of respiratory infection in the two groups was 68% and 67% respectively. Among them, the elderly who took vitamin E fell ill for about 19 days, with fever accounting for 37%, and the infection symptoms became more and more serious. However, the elderly who took placebo or sugar pills were sick for about 14 days, and fever accounted for 25%. This shows that the elderly who take vitamin E are more prone to fever when they are infected with respiratory tract, and the course of disease is longer and more serious.
4. Taking more than E400 mg of vitamin E every day can lead to headache, dizziness, nausea, blurred vision, menorrhagia or amenorrhea, and even thrombophlebitis and pulmonary embolism caused by platelet aggregation. This is especially important for the elderly, because pulmonary embolism can cause edema and atelectasis in the area near embolism, affect diffusion function and reduce arterial oxygen partial pressure, especially for the elderly with cor pulmonale or abnormal pulmonary vascular resistance before embolism, less embolism can cause pulmonary hypertension and then complications such as heart failure.
5. Take vitamin E800 mg or more every day for 3 weeks. Urine creatine and serum creatine kinase activity will increase, which can aggravate diseases such as hypertension, angina pectoris and diabetes.
When taking vitamin E2000 ~ 12000mg daily, reproductive dysfunction will occur.
