Of course. Inorganic iron (ferrous sulfate) can destroy vitamin E, so it cannot be taken at the same time. If you take a nutritional supplement containing a small amount of ferrous sulfate and take vitamin E at the same time, it must be 8 hours apart; Taking vitamin E varies from person to person. According to Li Keji, a researcher in the Sports Medicine Research Office of Peking University Third Hospital, vitamin E deficiency is very rare, especially in China, where the dietary structure of residents is mainly plant food and the intake of vitamin E is generally high. If there is no fat absorption disorder, vitamin E provided in the diet can basically meet the normal needs of the human body. However, a large number of clinical experiments have proved that vitamin E does have the function of preventing and treating diseases, but its specific dosage and method of use are still inconclusive. Associate researcher Wang Fu of Shanghai Second Military Medical University introduced the clinical application of vitamin E in treating various diseases at home and abroad. 1, the treatment of atherosclerosis has been reported abroad. Taking vitamins above 100 mg every day can slow down the progress of mild, moderate and severe coronary atherosclerosis. Daily vitamin C supplementation or multivitamins can not slow down the progression of coronary atherosclerosis. It is also reported that after taking 200 mg of vitamin E and 90,000 units of vitamin A 6 to 65,438+00 weeks, the symptoms such as headache, insomnia, dizziness and tinnitus will be alleviated, and blood pressure, blood lipid and cholesterol will be reduced. 2. Treatment of congestive heart failure and angina pectoris For these patients, vitamin E of E200 mg to 400 mg per day can increase the exercise load, make angina pectoris disappear and have diuretic effect. 3. Preventive and therapeutic effects on tumors Experiments in vitro and in vivo show that vitamin E can control the growth of tumor cells and reduce or delay the occurrence of tumors in vivo. Epidemiological data also show that the intake of vitamin E in human body is negatively correlated with tumor. For example, foreign studies have found that high-dose vitamin E can prevent hair loss caused by chemotherapy drug adriamycin. The general dose is 1600 mg per day, which should be taken 5 ~ 7 days before chemotherapy. 4, vitamin E and gynecological diseases Taking vitamin E capsules can cure some women's 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. Another literature reported that vitamin E can treat immune infertility, anovulatory infertility and habitual abortion. However, the research results of Finnish male smokers show that vitamin E can reduce the risk of ischemic heart disease and myocardial infarction on the one hand and increase the risk of bleeding, such as cerebral hemorrhage on the other. Therefore, vitamin E should not be taken in excess. Researcher Li Keji finally reminded readers that vitamin E deficiency is a rare disease, and it must be carried out under the guidance of a doctor when it is used to prevent and treat diseases. Don't be as eager for success as calcium supplementation. Precautions Vitamin E is usually nontoxic. When taken in large doses (per day 1, more than 200 international units), it can cause nausea, flatulence, diarrhea, rapid heartbeat and other adverse reactions. Please consult your health consultant before taking vitamin E when you have the following conditions: If you have high blood pressure. If you are using anticoagulants, such as sodium acetylcoumarin or side effects of vitamin E, taking vitamin E capsules can cure some women 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. Another literature reported that vitamin E can treat immune infertility, anovulatory infertility and habitual abortion. Taking more than E300 mg of vitamin E every day can reduce the immune function of the body, and the functions of T lymphocytes, B cells and monocyte-phagocyte systems in the body are low, which makes it easy to suffer from 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. Taking more than E400 mg of vitamin E every day can cause headache, dizziness, nausea, blurred vision, menorrhagia 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 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. 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. It can be seen that although vitamin E is one of the essential nutrients for the continuation of life, it still needs to be taken under the guidance of a doctor or dietitian for a long time to minimize side effects.
