Vitamin C and Vitamin E are vitamin C and vitamin E. Vitamin C is a water-soluble vitamin and vitamin E is a fat-soluble vitamin, and supplementation is recommended in cases of confirmed deficiency. Vitamin C is more effective when taken before meals, and vitamin E can be taken with meals. At the same time, vitamins should be taken in accordance with medical advice, not to increase the amount of their own, prone to adverse consequences, and regular follow-ups to check whether the disease has improved or recovery, follow medical advice again to adjust the dose: 1, vitamin C: belongs to the water-soluble vitamins, can be taken before meals on an empty stomach, because vitamin C in the stomach acid-rich conditions more stable decomposition, after eating the stomach may be alkaline environment, easy to destroy the vitamin C The composition of vitamin C is easily destroyed, resulting in too little absorption by the body. At the same time, vitamin C enters the small intestine under the action of stomach acid and is more easily absorbed by the body; 2. Vitamin E: belongs to the fat-soluble vitamin, which needs to be decomposed with the help of fat. After eating, due to the digestion of food in the stomach, it can stimulate the gallbladder to contract and promote the secretion and discharge of bile, which assists in the decomposition of vitamin E, allowing the body to better absorb it and achieve the supplementation effect. In addition, normal, healthy people who eat normally every day and have a balanced diet generally do not need to supplement vitamin C and vitamin E. Long-term supplementation may lead to the accumulation of large amounts of vitamin C and vitamin E in the body, which cannot be absorbed and discharged, and even cause adverse reactions in the body. In the case of pregnant women, adolescents, the elderly and other special groups, supplementation can be done as needed and in appropriate amounts.
