Why does the human body need vitamins and what are the vitamins that the human body needs?

The vitamins required by the human body are divided into two categories: fat-soluble and water-soluble vitamins, and the former includes vitamins A, D, E, and K. The latter include vitamins B (B1, B2, B6, B12), vitamin C, biotin, folic acid, niacinamide, pantothenic acid.

Vitamins are indispensable substances to ensure human growth and development, maintain life and enhance disease resistance. If the human body lacks vitamins, it will directly affect the body's various physiological activities and the metabolism of substances, and will suffer from various metabolic diseases. There are many causes of vitamin deficiencies, which can be summarized into a decrease in intake and an increase in need.

The former includes: incomplete vitamin intake due to too simple food varieties, or vitamin loss or destruction caused by improper cooking and processing; Others suffer from diarrhea or hepatobiliary diseases that affect the absorption of certain vitamins; or the long-term use of broad-spectrum antibiotics that affect the synthesis of intestinal bacteria, such as vitamin K; or the absorption of the vitamin itself can be affected by the interaction of the vitamin with other drugs. The latter include:

Patients with high catabolism, pregnant women, children, drivers, and people engaged in special jobs such as high-temperature work and special chemical work. Vitamins are very important for human growth and development, as well as physiological metabolism.

However, the more vitamins you supplement, the better. Excessive supplementation will be excreted with human urine, which not only causes waste but also increases the burden on the kidneys; In addition, too much vitamin A supplementation with some vitamins will also increase the burden on the liver, and excessive intake of vitamin C will cause hemolysis, stones, and diarrhea. Therefore, if it is used in large quantities for a long time, the result will not only fail to play its due role, but will cause adverse reactions and even lead to poisoning.

It is a class of organic substances necessary to maintain human life activities, and it is also an important active substance to maintain human health. Vitamins are found in very small quantities in the body, but they play an important role in the growth, metabolism, and development of the human body. The chemical structure and properties of various vitamins are different.

Vitamins are needed to participate in important biochemical reactions, such as vitamin B5 (pantothenic acid), which is a component of coenzyme A, which is an indispensable enzyme for cellular oxidative respiration.

Vitamins: They are essential for the human body. However, the human body cannot synthesize itself, so it must be obtained from food. Vitamins are involved in many important biochemical processes in the body.

The body's energy, protein and carbohydrate conversion are natural body protectors. Because it is antioxidant. Vitamins also work as enzymes.

Vitamins, also known as vitamins, are commonly speaking, life-sustaining substances, which are a class of organic substances necessary to maintain human life activities, and are also important active substances to maintain human health. Vitamins are found in small amounts in the body, but they are indispensable. Although the chemical structure and properties of various vitamins are different, they have the following things in common:

Vitamins are found in food in the form of provitaminostats;

Vitamins are not components of the body's tissues and cells, and it does not produce energy, its role is mainly to participate in the regulation of the body's metabolism;

Most vitamins cannot be synthesized by the body or are not synthesized in sufficient quantities to meet the needs of the body, and must be obtained frequently through food;

The human body's need for vitamins is very small, and the daily requirement is often calculated in milligrams or micrograms, but once the deficiency occurs, it will trigger the corresponding vitamin deficiency and cause damage to human health.

There are two main types of essential vitamins for the human body, one is fat-soluble vitamins and the other is water-soluble vitamins. There are four types of fat-soluble vitamins: vitamin A, vitamin D, vitamin E, vitamin K; There are nine types of water-soluble vitamins:

Vitamin B1, vitamin B2, vitamin B6, vitamin B12, folic acid, pantothenic acid, biotin, niacin (niacin comes in two forms: niacin and niacinamide), and vitamin C. Vitamins directly affect the absorption and metabolism of the human body, and once deficient, it can lead to related diseases.

Trace elements are needed for cellular nutrition. For example, vitamin D promotes bone growth.

There are four main types of essential vitamins for the human body: water-soluble vitamins and fat-soluble vitamins

Vitamin D, Vitamin E, Vitamin A, Vitamin K; Vitamin B2, vitamin B1, vitamin B12, vitamin B6, biotin, folic acid, pantothenic acid, niacin and vitamin C are water-soluble;

Vitamins directly affect the body's metabolic function.

Vitamins are a nutrient necessary to maintain the health of the body, and the human body can not synthesize or synthesize a small amount, can not meet the needs, need to be ingested from food a class of nutrients, there are more than 20 kinds of known at present. Although the human body needs it very little, they can neither produce heat and energy, nor are they the raw materials for the composition of body tissues and cells, but when there is a lack of any kind of vitamin, the physiological metabolism will be seriously affected, which is very important for maintaining human health.

Vitamins do not provide calories and do not constitute tissues, but they are components of the auxiliary components that are metabolized by proteins, sugars, and fats to release heat. They are also important substances that regulate the body's metabolism. If the human body lacks these vitamins, the metabolism cannot be carried out normally, sufficient energy cannot be obtained, growth is slow, development is stopped, resistance is reduced, and specific deficiency diseases occur, resulting in poor health.

Common vitamins are divided into two categories: fat-soluble vitamins and water-soluble vitamins

Fat-soluble vitamins include: vitamin A (including provitamin A), vitamin D, vitamin E, lipoic acid;

Water-soluble vitamins are: vitamin B group: vitamin B1 (thiamine), vitamin B2 (ribxanso), vitamin PP (niacin), vitamin B6 (pyridoxine), pantothenic acid (perdotic acid), biotin, folic acid, vitamin B12, choline, inositol, rutin, etc. and vitamin C (ascorbic acid).

There are four main types of essential vitamins: vitamin D, vitamin E, vitamin A, vitamin K; Vitamin B2, vitamin B1, vitamin B12, vitamin B6, biotin, folic acid, pantothenic acid, niacin and vitamin C are water-soluble; Vitamins directly affect the body's metabolic function. The main function of the human body is to promote the metabolism of the human body, which has great benefits for maintaining the health of the human body, but if you over-supplement vitamins, it is not good for the health of the human body, so if you want to supplement vitamins to your child, it is recommended to give your child more vegetables, fruits, and whole grains, which can be effectively supplemented, and the thirteen vitamins necessary for the human body include four fat-soluble vitamins and nine water-soluble vitamins.

Vitamin is a low molecular weight organic compound that cannot be synthesized and synthesized in very little amount in the human body, cannot meet the needs of the body, and must be supplied by food to maintain normal life activities. Vitamins are not components of the body's tissues, nor are they energy donors, but they play an extremely important role in regulating the metabolism of human substances and maintaining normal physiological functions, and are essential nutrients. Fat-soluble vitamins include vitamin A, vitamin D, vitamin E, and vitamin K.

In addition to being directly involved in influencing specific metabolic processes, most of them also bind to cell core receptors to affect the expression of specific genes. Fat-soluble vitamins are hydrophobic compounds that can be dissolved in fats, are often absorbed with lipids, and are transported in the blood in combination with lipoproteins or specific binding proteins, and are not easily excreted. It is mainly found in the liver in the body, so it does not need to be supplied daily.

Water-soluble vitamins include B vitamins, including vitamins B1, B2, PP, B6, B12, biotin pantothenic acid and folic acid, and vitamin C and lipoic acid. Water-soluble vitamins mainly constitute cofactors of enzymes in the body, which directly affect the activity of enzymes. Water-soluble vitamins depend on food, and excess water-soluble vitamins in the body can be excreted in the urine, and they are rarely accumulated in the body, and no poisoning occurs, but insufficient donors often lead to deficiency.

Normal is 12 recommended to buy a multivitamin to supplement your daily needs.
