Recommended intake of natural vitamin E

Vitamin E cannot be synthesized in the human body and needs to be taken in through diet. The daily requirement of vitamin E for adults in my country is 10 mg, and the specific daily recommended intake is shown in Table 2. The recommended intake for men and women is equivalent. α-Tocopherol equivalent (α-TE) is a commonly used vitamin E labeling unit. The specific calculation formula is as follows:

Total α-tocopherol equivalent (mg) = α-tocopherol (mg) + 0.5 × β-tocopherol (mg) + 0.1 × γ-tocopherol (mg) + 0.3 × tocotrienol (mg) + 0.01 × Delta-tocopherol (mg)

Vitamin E is considered to be a fat-soluble vitamin with no excess. When it is in excess, it can be converted into tocopherol lactone and excreted in urine or sweat. Therefore, the toxicity evaluation of vitamin E is very low. The U.S. Food and Nutrition Commission stipulates that the maximum daily intake of adults is 1000 mg. High-dose intake may cause gastrointestinal disorders.

Natural vitamin E application

Because of its antioxidant effect, natural vitamin E is used as an antioxidant, used in the preservation of fruits, vegetables, canned food and other foods, which can effectively prevent the oxidation and rancidity of oils in foods and greatly increase the storage period of foods. In addition, studies have found that vitamin E can enhance the skin's own resistance, thereby protecting the skin from air pollution and sun exposure. Therefore, vitamin E is widely used in skin care products, but the research on the skin care mechanism of vitamin E needs to be perfected. The antioxidant activity of vitamin E can also help resist free radical oxidation caused by oral problems, so that oral care products have anti-free radicals, promote ulcer healing and relieve gum pain. In order to ensure the effect, the concentration of vitamin E and its derivatives in oral care products needs to be above 0.1%
