The recommended daily intake for adults is 8 ~10iu;

60% ~ 70% of daily intake will be excreted with excrement. Different from other fat-soluble vitamins, vitamin E has a short storage time in human body, which is the same as vitamins B and C; Medical experts believe that the common oral dose of vitamin E should be 10 to 100 mg each time, 1 3 times a day. Large dose means more than 400 mg per day, and long-term use means continuous use for more than 6 months. Vitamin E contained in the general diet can fully meet the needs of the human body. Therefore, taking vitamin E for a long time is not only unnecessary, but also unsafe and has side effects.
