Vitamin E is a fat-soluble vitamin, and the best time to take it is 30 minutes after a meal. If taken orally three times a day, the best time to take it is 30 minutes after each meal, and it is best absorbed when taken with warm water. Because they are fat-soluble vitamins, it is usually not recommended to take them on an empty stomach or before a meal: 1) to neutralize the active ingredients with too much stomach acid; 2) to weaken their absorption and digestion, and to reduce absorption and metabolism. Fat-soluble vitamins, such as mixed fatty foods, are also relatively effective when taken at the same time, for example, they can be taken at the same time as meat, which can also play a mutual role in promoting their absorption and digestion. If taken orally once a day, it is recommended that it be taken with warm milk 30 minutes before bedtime for better results.
