Vitamin A: It is fat-soluble, and its main function on human body is to maintain the growth of various epithelial cells, promote the regeneration of rhodopsin, prevent night blindness and keratomalacia, and enhance the resistance to infectious diseases. The epithelial cells of the elderly are easily damaged and their resistance is relatively low. Therefore, it is necessary to supplement vitamin A properly. In addition to getting some from the diet (such as carrots, animal livers, dark vegetables, eggs and milk), you can also take vitamin A capsules, 1 time a day, 1 capsule each time, with a content of 25,000 international units, intermittently.
Vitamin E: It is fat-soluble, also called "tocopherol". Its main function on human body is to eliminate free radicals, resist oxidation and remove "lipid peroxide" and "lipofuscin" in the body, thus delaying the aging process of the body. Animal experiments have proved that vitamin E can prolong the average life span of animals and reduce the incidence of cancer. It leads to the increase of lipid peroxidation, obvious lipofuscin deposition, aggravated biofilm damage and muscle atrophy and thinning. Therefore, vitamin e should be supplemented. In addition to dietary intake (widely found in green plants, especially in various natural vegetable oils), oral vitamin E capsules, with a daily dose of more than 400 mg, may cause blurred vision, diarrhea, fatigue and other side effects, and should be avoided.
Vitamin C: water-soluble, also known as "ascorbic acid". The effect on human body is complicated, mainly to maintain the normal functions of blood vessels, muscles, bones, teeth and other organs. In particular, it can enhance the elasticity of capillaries and prevent bleeding, so it is called ascorbic acid. It can also increase the body's resistance to various infectious diseases, promote wound healing and accelerate the formation of connective tissue. For the elderly, it is of great significance to take vitamin C to increase their resistance to various infections. At the same time, keep blood vessels, especially capillaries in all parts healthy and prevent bleeding. It has special health care value for the elderly. Vitamin C tablets are not only taken from food (widely found in various fresh fruits and vegetables), but also can be taken orally, three times a day, 1-2 tablets each time (the content of each tablet is 100 mg), which can be taken for a long time and generally has no side effects.
Vitamin b 1: also known as thiamine, soluble in water, can prevent beriberi (especially peripheral neuritis caused by vitamin b 1 deficiency, not beriberi or athlete's foot), stimulate appetite, nourish nerves and improve muscle function. Taking vitamin b 1 plays an important role in rehabilitation when the elderly have poor appetite, symptoms of peripheral neuritis or indigestion. Vitamin b 1 is widely found in coarse grains such as cereals, wheat and soybeans. If the elderly eat refined white rice and flour for a long time, they may lack vitamin b 1. Oral supplement, three times a day, 2 tablets each time, the content of each tablet is 10 mg, which can be taken for a long time or intermittently.
In addition to the above four vitamins, other vitamins are generally not lacking, unless there are special diseases, a special vitamin can be considered (for example, anemia patients should use vitamin b 12, bleeding patients should supplement vitamin K, etc. However, vitamin A, vitamin E, vitamin C and vitamin b 1 are the most valuable supplements for health care and prevention. Of course, for the duration and dosage, it is best to consult the relevant doctor. 2 1 Jin Weita and gold partner are more suitable for the elderly.
