Extended data
Compared with other fat-soluble vitamins, oral vitamin E is relatively less toxic, and taking large doses of vitamin E may interfere with the absorption of vitamin A and vitamin K. Large doses of intravenous vitamin E increase the risk of bacterial and fungal septicemia in premature infants, which may inhibit the ability of normal neutrophils to kill bacteria and fungi. Vitamin E oral preparation with high permeability is considered to be related to increasing the risk of necrotizing enteritis in premature infants, which may be attributed to the permeability of the formula.
During pregnancy, the requirement of vitamin E is increased to meet the needs of fetal growth and development. Vitamin E can be secreted by breast milk, and the content of vitamin E in mature breast milk is about 4mg/L, so lactating mothers should increase their intake to make up for the loss in breast milk. For infants, the recommended intake of vitamin E is based on breast milk (about 2mg/d). Vitamin e is best supplemented by food. Vitamin E mainly exists in green vegetables, animal livers, beans, egg yolks, melons and fruits, lean meat and peanuts.
