According to the recommended daily vitamin scale formulated by China Nutrition Society, the recommended basic daily intake of people over 4 years old (including pregnant women and lactating mothers) is 14 mg. We consume a certain amount of vitamin E through our daily diet, so it is the most scientific to consume about 7.525mg of natural ve every day. At present, the contents of products on the market are different. The dosage of Yangshengtang and Amway is 100mg, which may cause vitamin E poisoning if taken for a long time, so it is suitable to supplement when vitamin E is extremely deficient, but not suitable for daily supplement.
