Vitamin E generally works best when taken about half an hour after a meal. Vitamin E is a powerful antioxidant with anti-aging and anti-cancer effects, which can improve the immunity of the body, whiten and strengthen the skin, enhance the function of internal organs, and maintain adequate physical strength and energy. Vitamin E is absorbed by the small intestine after taking, if there is no food in the gastrointestinal tract, the drug will be quickly absorbed into the blood, resulting in a higher concentration of vitamin E in the blood and quickly excreted through the kidneys and urinary tract, which cannot be fully utilized by the body and reduces the efficacy of the drug, so it is not recommended to take it on an empty stomach. Vitamin E is a fat-soluble vitamin and is best absorbed after meals, especially after eating foods containing appropriate fats and oils. Vitamin E should not be taken in excessive amounts, and it is recommended that the drug be used appropriately under the guidance of a physician. The human body cannot synthesize vitamin E, but can only take it from food, such as vegetable oils, nuts, green leafy vegetables, dairy products, eggs, etc., all rich in vitamin E.
