VA: Vitamin A helps maintain healthy skin and mucous membranes.
Also known as retinol or anti-dry eye factor, it is an unsaturated monohydric alcohol with alicyclic ring, including animal food sources, vitamin A1 and A2. It is a class of substances with retinol biological activity. Can be derived from carrots in plants. Its main function is that it is a fat-soluble alcohol, which mainly exists in the liver, blood and retina of the eyeballs of animals, so it is also called retinol, which constitutes the rhodopsin part of the visual cells that feels weak light.
If the human body lacks vitamin A, dry skin, desquamation, and hair loss will occur. The main function is to maintain normal vision, maintain the health of epithelial tissue cells and promote the synthesis of immune globulin, maintain normal growth and development of bones, and promote growth and Reproduction, inhibiting the growth of tumors, is also a nutritional supplement.
VD: Vitamin D can promote calcium absorption.
Vitamin D (vitamin D) is a complex derivative of sterols with anti-rickets effect, also known as anti-rickets vitamin.
It is currently believed that vitamin D is also a steroid hormone. The most important members of the vitamin D family are VD2 (ergocalciferol) and VD3 (cholecalciferol). Vitamin D is the derivative of different pro-vitamin D after ultraviolet irradiation.
For outdoor activities, as long as the human body receives enough sunlight, enough vitamin D can be synthesized in the body. In addition to fortified foods, natural foods usually contain low vitamin D content. Animal foods are the main source of natural vitamin D in non-fortified foods, such as sea fish and fish eggs with high fat content, animal liver, egg yolk, cream and cheese. Relatively more, and lean meat, milk, nuts contain trace amounts of vitamin D, while vegetables, grains and their products and fruits contain a small amount of vitamin D or almost no vitamin D activity.
VB1: Vitamin B1 helps maintain the normal physiological functions of the nervous system.
Vitamin B1 is also known as thiamine or antineuritis. A kind of B vitamins formed by the combination of pyrimidine ring and thiazole ring. It is white crystal or crystalline powder; it has a faint special smell, bitter taste, and moisture attracting property. It is easy to absorb water when exposed to the air. It is easy to decompose and deteriorate in alkaline solution. When the pH is 3.5, it can withstand a high temperature of 100 degrees Celsius, and it is easy to fail when the pH is greater than 5. When exposed to light and heat, the potency drops. Therefore, it should be stored in a shading, cool place, not long-term storage.
It is stable in acidic solutions, but unstable in alkaline solutions, and is easily damaged by oxidation and heat. Vitamin B1 is mainly found in the outer skin and germ of seeds. It is rich in rice bran and bran, and it is also rich in yeast. The content of lean meat, cabbage and celery is also richer.
The vitamin B1 currently used are all chemically synthesized products. In the body, vitamin B1 participates in the catabolism of sugar in the form of coenzymes, which has the effect of protecting the nervous system; it can also promote gastrointestinal motility and increase appetite.
When vitamin B1 is deficient, it can cause a variety of neuroinflammation, such as beriberi bacteria. Polyneuritis caused by vitamin B1 deficiency, the patient’s peripheral nerve endings are inflamed and degenerated, accompanied by symptoms such as numbness of the limbs, muscle atrophy, heart failure, and edema of the lower limbs.
VC: Vitamin C can promote the absorption of iron.
Vitamin C is the commonly used abbreviation for vitamin C. VC (vitamin C) generally refers to vitamin C.
Vitamin C in food is mainly found in fresh vegetables and fruits, and cannot be synthesized by the human body. Fresh jujube, wild jujube, orange, hawthorn, lemon, kiwi, sea buckthorn and prickly pear are rich in vitamin C in fruits; green leafy vegetables, green peppers, tomatoes, and Chinese cabbage are high in vegetables.
Niacin: Niacin helps maintain the health of the nervous system.
Niacin is also called vitamin B3 and vitamin PP. In the human body, it also includes its derivatives, ammonia hydrochloride or nicotinamide, which is one of the 13 essential vitamins for the human body. It is a water-soluble vitamin and belongs to the vitamin B group. Niacin is converted into nicotinamide in the human body, which is a component of Coenzyme I and Coenzyme II, and participates in the metabolism of lipids in the body, the oxidation process of respiration, and the process of anaerobic decomposition of sugars. Niacin and niacinamide are both soluble in water and alcohol; the properties of niacin and niacinamide are relatively stable, and will not be destroyed under high pressure at 120°C for 20 minutes. Once processed and cooked, the loss is small, but it will lose with water. Iron: Iron is an important component of red blood cell shape.
Calcium: Calcium is the main component of bones and teeth and maintains bone density.
Calcium is one of the most common elements in the human body. The content of calcium in the human body accounts for 1.5-2% of the total body weight, of which bones and teeth account for about 99%. Body fluids and soft tissues accounted for 1%. It plays an important role in human metabolism, cell function, nervous system operation, and protein hormone synthesis.
Zinc: Zinc helps improve appetite.
Zinc supplementation is to supplement the essential trace element zinc for the human body. Zinc supplementation plays an extremely important role in human growth and development, immunity and vitamins.
Zinc exists in many enzyme systems, such as carbonic anhydrase, respiratory enzyme, lactate dehydrogenase, superoxide dismutase, alkaline phosphatase, DNA and RNA polymerase, etc. It is the synthesis of nucleic acid, protein and carbohydrate It is an essential substance for the use of vitamin A. It has the effect of promoting growth and development and improving taste. When normal food is difficult to ensure nutrition, the World Health Organization recommends the use of zinc salt as a supplement.
