Everyone knows that the benefits of vitamina and for the whole organism is very large. Therefore, it is important to use the necessary number of products to use it every day, and it is necessary to take into account the rules for cooking and storage for better absorption of vitamin.

In its composition, vitamin A is classified on substances similar in its composition - retinoids and carotenoids, and may be of different origin. Substances - retinol and beta-carotene are considered the most common and useful. The first can be obtained from animal products, such as meat, liver, chicken eggs, butter and milk, and the second is rich in vegetables and fruits, especially bright colors.

Retinol - Vitamin A, has high biological activity, therefore it is of great value in human nutrition.

Beta-carotene falling into the body breaks into two molecules and gives pure vitamin A, the remaining part accumulates in the body and remains for a long time without changing the carotenoid, which provides a temporary reserve, and if necessary, beta-carotene again produces Vitamin A.

What impact has vitamin A

A group of vitamins A plays an invaluable role for the whole organism. It helps to improve the work of the organs of view, strengthen bone tissue and skeleton, improves the operation of the musculoskeletal system, promotes the formation of the mammary glands, improves the metabolism, prevents the occurrence of cancer cells, contributes to the skin rejuvenation, improves the work of the thyroid gland, strengthens the immunity, improves the condition of hair and Nail and more. And it is only its main properties, you can list everything for a very long time. Therefore, the daily use of vitamin A in the food diet is necessary for all, and especially people, often suffering out cold and flu, food disorders that have weak vision, as well as with large physical and mental loads, especially children, pregnant women and nursing women, athletes.

How much do you need to eat vitamin A per day

Daily average daily rate of vitamin A consumption in the food diet for an adult healthy person 5000mm, which is 1.5mg. However, this amount should be adjusted based on a number of features of the body. It is important to take into account the floor, body weight, age, the presence of diseases. Pregnant and lactating women consumption of vitamin A is recommended slightly above the standard norm. Children are reduced to 800 micrograms.

When using synthetic vitamins, you must follow the instructions where the dose is already adjusted. Or should recommend the recommendations of the doctor who appointed you an individual norm for certain reasons.

What is dangerous vitamin A shortage in the body

With a lack of vitamin A human body, many problems arise:

the vision is reduced, conjunctivitis appears, in some cases the so-called "chicken blindness" may occur when a person loses the ability to see with weak lighting. In addition, the mucous eye dryness dries, as a result of which the accumulation occurs in the angles of the pus and mucus in the corners, tear increases, the vision is combined;

there is a drying of the skin, which provokes its accelerated aging;

hair and skin of the head dry up, dandruff appears, seborrhea;

dental enamel loses strength, begins to collapse, caries develops;

the whole digestive system suffers;

a person more often sicks with colds and infectious diseases, heavier tolerates them;

there is insomnia, lack of sleep, exhaustion, the overall body fatigue.

for women, the lack of vitamin A is fraught with diseases of childbearing organs;

Men decreases potency.

What caused a shortage of vitamin A

Incorrect, defective nutrition, frequent diets, diseases of the digestive system, contribute to the development of avitaminosis, in particular the lack of vitamin A. Also vitamin A is not absorbed by the organism without vitamin E (there is a rapid oxidation of retinol in the human body). Therefore, it is necessary to use these two vitamin in the complex.

However, the negative impact on the body has not only a shortage of vitamin A, but also its excess.

In this case, a number of negative consequences for the body may be observed, namely:

the liver and spleen may increase in size;

there are disorders in the functions of the digestive system;

there is an excessive hair loss, dandruff appears, seborrhea, nails are bothering and become fragile;

pigment spots may appear on the skin;

often excess vitamin A is accompanied by nausea;

failures in the women's menstrual cycle occur.

However, it is quite difficult to achieve the organism's oversaturation. This is mainly due to excessive use of synthetic polyvitamins. When consuming a large number of natural products that are rich in the content of group vitamins A, as a rule, excess does not occur. But do not forget that it is categorically impossible to eat for a long time, it may lead to serious irreparable consequences. And when detecting symptoms of overdose, it is necessary to immediately abandon the consumption of products rich in vitamin A, replacing them on foods saturated with vitamin C.

In which products contains vitamin A

Vitamins of group A are contained in products of plant and animal products. The largest number of retinol contains fruits and vegetables having a bright orange or green color. Vitamin A rich liver, butter, bird eggs, fish oil, dairy products. Also, the large percentage of beta carotene is also contained in hawthorn and in dandelions. For better assimilation by the body of vitamin A, the presence of fat in small doses is necessary. This is necessary in order for the production of gastric juice that ensures the synthesis of finished vitamin A. also to process this group of vitamins need tocopherol and choline. That is why it is recommended for vegetable salads to use a small amount of sour cream, vegetable or olive oil as a refueling.

Interaction of vitamin A with other vitamins and drugs

For the best digestibility of vitamin of this group, it is recommended to jointly take vitamin E, B, phosphorus, potassium, calcium, zinc.

Today in pharmacies you can see a wide variety of complex vitamins. However, not all of them contain the optimal ratio of trace elements, so they should be treated very carefully. It is also not necessary to abuse them with application, strictly observe the instructions and drink only if necessary, it is advisable to consult a doctor.

IMPORTANT! When taking vitamin A try to avoid drinking alcohol, as their interaction can cause violations in the work of the liver, as well as lead to its serious diseases. In addition, with the use of any vitamin, including groups, but not to use laxatives, as they reduce their assimilation (with the exception of laxatives of plant origin).

How to achieve better vitamin A digestibility

In order to obtain the maximum benefit from consumption of products, it is necessary to comply with several rules for their storage and cooking. What is contained vitamin and we already know, now let's talk about what is better to do with them.

So that beta carotene is better absorbed by the organism of vegetables, it is recommended to boil or finely cut. But this rule is not suitable for all products, for example, when cooking cabbage decreases the benefits of vitamin A, therefore it will be more useful to use it in the raw form.

Solar rays and oxygen contribute to the destruction of vitamin A, so it is not recommended to store products in an open space under the influence of direct sunlight.

The benefits of vitamin A will be more if you prepare together products containing beta-carotene and tocopherol.

It is best to cook for a couple or grilled.

Quantitative content of retinol in milk depends on the season. In the spring and summer it is significantly larger, since only natural fresh herbs use in feeding cows, they are very rare to artificial additives.

Fruits best choose bright red or orange colored, they contain the largest amount of vitamin A.

Full nutrition ensures the health of the whole body, improves well-being and mood. And also makes it possible to avoid many diseases and ailments. Therefore, it is important to correctly adjust your daily diet and consume all products in sufficient quantities.

Undoubtedly, it is best to consume non-synthetic vitamins, but to get them in natural foods in the diet.

• provitamin A (Carotine): vegetation analogue of vitamin, which is already in the body becomes retinol.

Retinol pale yellow color, which appears from the red pigment of vegetable origin - beta-carotene. One of the advantages of the substance is its resistance to high temperatures.

This substance may form the following compounds:

• Retinoic acid;
• Retinol;
• Retinolacetate;

Vitamin A itself is an unintended cyclic alcohol. It is capable of oxidizing inside the body and to form retinuous acid and a-aldehyde in this way.

Already in past centuries, scientists tried to find out where Vitamin A. It turned out that its number in animal products primarily depends on whether this vitamin animal consumed. For this reason, in the cow's oil of this vitamin much less than fishing fat, as the fish feed on plant plankton rich in vitamin A.

• fish fat;
• liver (primarily beef);
• butter;
• eggs (especially yolks);

2. Secondary stage. Clinically, you can set the lack of elements. A person is subject to a disease associated with the weakening of immunity.
3. Third stage. There comes a complete shortage of vitamin, the ability of its absorption into the body is disturbed. There are diseases associated with the lack of the desired number of retinol. Their treatment is starting only after restoring the desired amount of vitamin in the body.

Before passing the blood test to vitamin A, it is impossible to have a minimum of two hours, but it is allowed to drink water without gas, additives and sweeteners. For half an hour before analyzes, it is forbidden to smoke.

Such a kind of study is prescribed with chicken blindness and pathologies that prevent the suction of nutrients in the intestine. It is also often prescribed to determine the level of toxicity caused by excessive use of vitamin A.

Normal is the amount of vitamin in the blood, equal to 0.3 - 0.8 μg / ml. This means that there is enough vitamin in the body at the time of blood fence.

About retinol

The first vitamin that was opened by science was Just Vitamin A. It happened in 1913. And since he was the first, he got the first letter of the alphabet, and the name was formed from the English word Carrot (carrots) - from which first was allocated predecessor of vitamin A - carotene (Provitamin A).

Carotine, retinol and vitamin A is not the same. Carotine is contained in vegetable food. Our body synthesizes from Karotina Vitamin A. And Retinol is in the food of animal origin. Vitamin A itself is very unstable and in preparations it has to replace Retinol compounds, but vitamin A. is also allocated in the body of them

Refers to fat-soluble vitamins - while in the water, it does not dissolve at all.

In adults, in the process of life there is a fat tissue accumulation and with a shortage of vitamin A, these reserves go to the move. But in children of such reserves there is almost no hypovitaminosis and more likely.

Often on packages with vitamins and vitamin complexes, the dosage of retinol is presented in mg and μg, and in Me, that is, international units.

1 me \u003d 0.3 μg. Retinol, 0.6 μg.β-carotene, 1.2 MHK. other varieties of vitamin A

Later began to measure in units of ER (equivalent of retinol).

1 er \u003d 1 μg. Retinol, 2 μg.β-carotene (oil solution), 6 μg. β-carotene (in food), 12 μg.α-carotine

Today in the course of another unit of measure (the newest) - 1 RAE (equivalent of retinol activity).

1 RAE \u003d 1 μg. Retinol, 2 μg.β-carotene (oil solution), 12 μg. β-carotene (in food), 24 μg. Other Provitaminov A.

Retinol Acetate and Retinol Palmitate: Difference and what is better

Retinol acetate - acetic acid salt

Retinol Palmitate - Palmitic Acid Salt

First, both synthetic substances, that is, produced industrially.

Secondly, 1 mg. Retinol acetate is 2907 me vitamin A,
1 mg. Retinol Palmitate is 1817 me vitamin A, respectively, dosage will be different.

Thirdly, acetate was developed and was produced mainly for the treatment of animals, but Palmitate for people.

Fourth, the production of acetate is cheaper than palmitate, so acetate is more distributed in pharmacies.

Fifth, it is believed that palmitate is more natural for the body (since palmitic acid is present in the body) and is better absorbed and faster, and the acetate is worse than the body (nor acetic acid, nor its salts in the body), more resources and time spent on his decomposition and suction.

How to take (in medicinal purposes)

Take preparations both inward and externally, as well as in the form of injections intramuscularly.

Tablets and dragee are accepted after eating several times a day.

Solutions inside - a pair of droplets (up to 6) 1 time per day in the morning or evening.

Outdoor application - compresses 5-6 times a day.
