Patient's question:
Can vitamin E capsules be used for beauty?Doctor's answer:
This product's main ingredient is: Vitamin E. Drug Category: Vitamins and Mineral Deficiency Medications. Indications: 1. Used for newborns, premature infants, and low birth weight infants born to mothers who have not consumed fortified or have severe fat malabsorption. 2. Routine use of this product in immature infants and low birth weight infants can prevent hemolytic anemia caused by vitamin E deficiency, and can reduce the formation of posterior pole fibrosis (which can lead to blindness) and bronchopulmonary system development due to oxygen toxicity. However, some people believe that the above effects still need further research confirmation. 3. Used as an adjuvant treatment for progressive muscular dystrophy. Characteristics: Pharmacology and Toxicology: Vitamin E is a basic nutrient, and its exact function is still unclear. It is an antioxidant that can combine with selenium in the diet to prevent polyunsaturated fatty acids in membranes and other cellular structures from suffering free radical damage; protect red blood cells from hemolysis, protect nerves and muscles from oxidative free radical damage, and maintain the normal development and function of nerves and muscles. It may also serve as an auxiliary factor for certain enzyme systems. Pharmacokinetics: 50% to 80% are absorbed in the intestine (duodenum), and absorption requires bile acids, dietary fat, and normal pancreatic function. It binds to blood β-lipoproteins and is stored in all tissues, especially in adipose tissue, with storage levels as high as 4 years' worth. It is metabolized in the liver, excreted through bile and the kidneys. Dosage and Administration: Oral: 1. Adults: (1) Daily requirement of Vitamin E: Male adults 10mg (16.7U), female adults 8mg (13U), pregnant women 10mg (16.7U), lactating women 11~12mg (18~20U). The above doses can be supplied by a normal diet. (2) Vitamin E deficiency: Treatment dosage varies depending on the degree of deficiency. Common dosage: Adults, 10~100mg per time, 2~3 times a day. 2. Children: (1) Daily requirement of Vitamin E: Newborns to 3 years old 3~6mg (alpha-TE is the same below, 5~10U), 4 years to 10 years old 7mg (11.7U). (2) Vitamin E deficiency: Children 1mg/kg per day, premature infants 15~20mg per day. Chronic cholestatic infants should take water-soluble Vitamin E preparations orally 15~25mg per day. Adverse Reactions: 1. Long-term use of large amounts (400~800mg per day) may cause blurred vision, breast enlargement, diarrhea, dizziness, influenza-like syndrome, headache, nausea, stomach cramps, and fatigue. 2. Long-term use of excessive amounts (more than 800mg per day) may cause bleeding tendency in vitamin K deficiency patients, alter endocrine metabolism (thyroid, pituitary, and adrenal glands), alter immune mechanisms, affect sexual function, and carry the risk of thrombophlebitis or embolism. Contraindications: Precautions: 1. Interference with diagnosis: Large amounts of vitamin E can increase serum cholesterol and serum triglyceride levels. 2. Caution should be exercised in patients with hypoprothrombinemia caused by vitamin K deficiency and iron deficiency anemia to avoid worsening the condition. 3. Vitamin E activity is now measured in alpha-tocopherol equivalents (alpha-TE) instead of units (U), but most manufacturers still use U to indicate vitamin E activity. 1U of vitamin E is equivalent to 1mg of dl-alpha-tocopheryl acetate, equivalent to 0.7mg of d-alpha-tocopherol, and equivalent to 0.8mg of d-alpha-tocopheryl acetate. 4. If the diet is insufficient in selenium, vitamin A, or sulfur-containing amino acids, or contains a large amount of unsaturated fatty acids, the need for vitamin E will increase significantly. If this product is not supplemented in time, it may lead to a deficiency. Use in Pregnancy and Lactation: When pregnant women consume a normal diet, there has been no confirmed evidence of vitamin E deficiency. Vitamin E can partially pass through the placenta, and the fetus only receives 20%~30% of the mother's blood drug concentration. Therefore, low birth weight infants may suffer from a deficiency after birth due to insufficient storage. Use in Children: Use in Elderly Patients: Drug Interactions: 1. Large amounts of aluminum hydroxide can cause bile to precipitate in the upper small intestine, reducing the absorption of lipid-soluble vitamin E. 2. Avoid the concurrent use of coumarins and their derivatives with large amounts of this product to prevent the occurrence of hypoprothrombinemia. 3. Cholesterol-lowering drugs such as cholestyramine and colestipol, mineral oil, and aluminum hydroxide can interfere with the absorption of this product. 4. Iron supplementation for iron deficiency anemia increases the need for vitamin E. 5. This product can promote the absorption of vitamin A, increase the storage and utilization of vitamin A in the liver, and reduce the occurrence of vitamin A toxicity; however, excessive amounts can reduce the storage of vitamin A in the body.
