But we should know that it is a three-point poison, and taking vitamin E in large doses for a long time will also cause poisoning and endanger health.
Experts point out that the daily intake of vitamin E should not exceed 400 mg. If it exceeds 800 mg per day, symptoms of poisoning may occur. Long-term (more than half a year) taking 300 mg a day may also produce adverse reactions. Common adverse reactions are as follows:
(1) Excessive or long-term use of vitamin E may cause the following symptoms: hypertension, hypoglycemia, headache, dizziness, nausea, fatigue, etc.
(2) Excessive use of vitamin E, exceeding 400 mg per day, can cause urticaria, dermatitis, stomatitis and chapped lips. (3) Taking a large amount of vitamin E for a long time can cause vitamin A deficiency, leading to night blindness, dry eye, photophobia and eye fatigue.
(4) Taking vitamin E for a long time can increase the concentration of serum triglyceride and cholesterol.
(5) Long-term use of vitamin E can cause skeletal muscle weakness, fatigue, myalgia, reproductive dysfunction and gastrointestinal symptoms (abdominal pain, diarrhea, colic, etc. ). The above symptoms can gradually disappear after drug withdrawal.
(6) Long-term use of vitamin E can cause platelet aggregation, and thromboembolism, pulmonary embolism and thrombophlebitis can occur.
(7) Women who take this product in large quantities for a long time can cause vaginal bleeding, breast hypertrophy, breast tumor, etc.
(8) Anyone suffering from angina pectoris and diabetes, taking too much vitamin 400 mg or more) can obviously aggravate the symptoms. Therefore, patients with angina pectoris are limited to a small dose of 100 ~ 200mg per day.
As can be seen from the above, although vitamin E is a nutrient, it cannot be taken in excess.
