Are vitamins harmful? The role of vitamins. Table of vitamins

Everyone knows about the benefits of vitamins for health. They help our body function correctly, give us courage, increase efficiency, help to develop intellectually and to withstand the adverse effects of the environment. Needless to say, vitamins make us healthy and strong.

Vitamins - is it good?

This golden rule is known to everyone, as this information is brought to us from early childhood. Caring mothers, trying to give their child only the best, carefully approach the nutrition of the child, choose foods that are enriched with vitamins. So it was led: a person lives with full confidence that vitamins are a colossal blessing. And the more of them, the better. There is such a view: everything associated with these substances is certainly beneficial to the body. Is it really? Scientists claim that vitamin Vitamin is different. If you are talking about biologically active substances, the sources of which are natural products, then, of course, such an organism does not hurt. Moreover, doctors strongly recommend to include in the diet foods rich in vitamins, to meet the daily needs of the human body. Lack of them in the body leads to the development of scarce conditions and the emergence of various diseases. But one should not go into the other extreme. In this matter there is a golden axiom: a lot does not mean good. Excess consumption of biologically active components can harm the body no less than their deficiency. But it can reassure the fact that the overabundance of vitamins with food is very difficult to obtain. For this, you need to eat products in tons.

Are pharmacy vitamins similar to natural ones?

Another matter - synthetic derivatives. Such types of vitamins for the human body are foreign products. If you carefully study their composition, you can find the following fact: in the vitamin complex many biologically active substances are present in quantities many times greater than their daily requirement. In addition, synthetically produced substances differ from natural analogues and have other properties. This is due to a phenomenon that scientists call isomerism. Two substances having the same chemical formula, but differing from one another in structure, will have different properties and, as a result, have a different functional effect. Knowing this fact, involuntarily you will think over a question: whether vitamins from a drugstore for health are harmful?

Should I believe in advertising?

Pharmaceutical companies claim in advertising slogans that by taking their product, we and our children will be healthy, beautiful and intelligent. In Russia, the market, representing synthetic types of vitamins, is simply overflowing with supply. And this is not an accident, as there is an increased demand for this type of medicines. Russia is now experiencing a real vitamin boom, while all progressive humanity has questioned the benefits of pharmacy vitamins.

Shocking facts about vitamins

To the question: "Are vitamins harmful from a pharmacy?" Modern science confidently answers: the use of synthesized drugs without having certain medical indications for this is not only not useful, but also capable of causing irreparable damage to health. This statement was based on serious scientific research involving a large number of people.

What did the scientists find out?

As a result of these studies, which were carried out by European specialists, it was possible to find out the following facts:

• Synthetic beta-carotene in combination with vitamin A can increase the risk of death from gastrointestinal cancer by 30%.
• The same synthesized beta-carotene in a compartment with vitamin E increases the risk of oncology by 10%.
• There is no natural deficiency in the body of vitamin E, but its slightest excess causes fatigue, headache, visual impairment and muscle atony.
• Also, there was no natural vitamin deficiency of vitamins H, B ₃ , thiamine, pyridoxine, folic acid and choline. However, their overdose can cause serious damage to the body. For example, hypervitaminosis of pyridoxine causes serious disorders of the human nervous system: neuropathy, loss of sensitivity, muscle atony.
• Daily intake of 20 mg of synthetic beta-carotene increases the probability of acute cardiovascular insufficiency by 13%, lung cancer by 18%.
• Higher doses with the intake of vitamin C lead to thickening of the vascular walls of the blood vessels of the brain and can cause atherosclerosis.
• Vitamin C in combination with aspirin in most cases leads to peptic ulcer and stomach cancer.
• Excess intake of vitamins fat-soluble group (E, A, D, K) leads to allergies, migraine and the formation of kidney stones.
• Excess of vitamin PP leads to abnormalities of the digestive tract, aggravates the course of bronchial asthma, increases the content of uric acid in the blood.
• Hypervitaminosis of vitamin A can lead to severe visual impairment, digestive system activity, fetal death and other functional disorders in the body of a pregnant woman.
• Excess vitamin B ₁ can cause tremors, nervousness, allergies, swelling and intensify herpes.
• An overdose of vitamin B ₂ causes dermatitis and numbness.
• A search with vitamin E leads to an increased risk of thrombosis and increased blood pressure, impaired intestinal functions with diarrhea and dysbiosis.
• Excess of vitamin B ₁₂ will show up in abundant skin rashes.
• Folic acid taken without measure, provokes allergies, impaired activity of the gastrointestinal tract, serious sleep disorders.
• Excess of vitamin B ₁₅ provokes arterial hypertension.
• Vitamin D, taken in excessive doses, can cause irritability, digestive disorders, unquenchable thirst, weakness, frequent urge to urinate, calcium deposits in the vessels of the whole organism.

After reading these conclusions of scientists doubts about whether vitamins of synthetic manufacture are harmful, should be completely flushed. However, the volume of their industrial production does not decrease, nor does demand. Do not become a victim of importunate marketing, you need to seriously think about your family's health.

What vitamins are better for humans?

Scientists say that the needs for vitamins in each person are individual and it is impossible to satisfy them with one, the more artificially created drug. The unique structure of natural biologically active compounds and their combination is simply impossible to replicate in a synthetic way. The conclusion suggests itself: the best vitamins for the human body are contained in the foodstuffs that nature itself generously provides to us. Biologically active substances in natural products are always accompanied by a whole group of active components, which contribute to their best absorption by the human body. That is why the effectiveness of natural vitamins is much higher than pharmacy counterparts. The best source of biologically active substances for a person is food. The vitamins contained in it are familiar to the body and are absorbed completely without harm to it.

The Importance of Vitamins in Human Life

The role of vitamins in human life is very high. These microscopic structures perform the regulation of all vital processes at the cellular level. As a result, a normal mechanism of formation of all structural components and regulation of metabolism is realized.

Functions of vitamins in the human body

Each of them performs its own special function in the body:

• Vitamin A (axerophthol, retinol) is responsible for the growth, skin condition and human immunity.
• Vitamin B ₁ regulates the work of muscles, central and peripheral nervous system, is a constituent element of enzymes, regulates the metabolism of carbohydrates and amino acids.
• Vitamin B ₂ (riboflavin) is responsible for the growth and regeneration of cells, regulates the exchange of proteins, fats and carbohydrates, supports vision.
• Vitamin B ₃ (pantothenum) participates in the general process of metabolism, it enters into a combination of enzymes of digestion.
• Vitamin B ₆ (pyridoxine) is responsible for the amino acid and lipid metabolism.
• Vitamin B ₁₂ (cyanocobalamin) is responsible for maintaining normal blood counts, is involved in the synthesis of nucleic and amino acids, triggers the exchange of fats and carbohydrates, regulates the digestive and nervous system.
• Vitamin C is responsible for strong immunity and elastic vessels, it affects favorably on the CNS, the work of the endocrine glands and is an oncoprotectant.
• Vitamin D is responsible for the exchange and assimilation of calcium and phosphorus in the human body, prevents the development of rickets.
• Vitamin E (tocopherol) is responsible for the normal functioning of the human reproductive system. Regulates protein and lipid metabolism, supply of tissues with oxygen, prolongs the youth of all tissues of the body. Being a natural antioxidant, preserves the potential of retinol.
• Vitamin PP (niacin) regulates enzyme activity, protein metabolism and cellular gas exchange, brain activity and digestive function.

How to recognize the lack of vitamins in the body?

Vitamins are highly specific. For each of their kind there is such an individual concept as the daily need. This amount is physiologically necessary for the human body to function normally. If there is a defect, hypovitaminosis develops, and if hypervitaminosis occurs, hypervitaminosis occurs. About what vitamins are not enough in the body, often say external manifestations: the state of hair, skin, nails, mucous membranes, as well as a predilection for certain foods.

Signs of Vitamin Deficiency

About the shortage of these or other vitamins will tell the following signs:

• Pale skin and their peeling, loss of hair, loss of appetite indicate a lack of biotin.
• Weakness, anemia, dizziness and fatigue indicate a lack of vitamin B ₁₂ .
• The frequent incidence of ARI and ARI, increased fragility of the vessels indicates a deficiency of ascorbic acid.
• Increased nervousness and headaches can talk about vitamin B deficiency.
• Problems with the skin in the form of cracks and eruptions indicate a deficiency of vitamin B ₂ ;
• Disturbance of appetite and sleep, edema and heart problems can be a consequence of a lack of vitamin B ₁ .
• Visual impairment, rashes and dry skin, decreased immunity, hair deterioration may occur due to a lack of retinol.
• A poor indicator of blood coagulability and wound healing indicates a lack of vitamin K.
• Vitamin D, the lack of which is expressed in increased nervous excitement and convulsions, is also very important for the body.

By these signs, you can calculate the necessary vitamins and adjust the diet. But it is worth remembering that such a diagnosis can only be made by a doctor.

Table of vitamins

Below is a table of vitamins, which indicates the name (letter designation and trivial name), the daily requirement for this substance for the human body and food products that contain it in the greatest amount. Products can be both vegetable and animal. Note also that vitamins are divided into fat-soluble and water-soluble. Such information is useful when you know exactly what vitamins are missing. This table will be very useful for correcting nutrition and making up a daily diet.
