Everyone knows about the health benefits of vitamins. They help our body to function properly, give us vitality, increase efficiency, help to develop intellectually and withstand the adverse effects of the environment. Needless to say, vitamins make us healthy and strong.
Are vitamins good?
This golden rule is known to all, as this information is heard from early childhood. Caring mothers, trying to give their baby only the best, carefully approach the baby’s diet, choose foods enriched with vitamins.
And so it happened: a person lives with full confidence that vitamins are a tremendous blessing. And the more of them, the better. There is such an idea: everything connected with these substances is certainly beneficial for the body. Is it really? Scientists say that
vitamin A is different. If we talk about biologically active substances, the sources of which are natural products, then, of course, you will not harm such an organism. Moreover, doctors strongly recommend the inclusion of vitamin-rich foods in the diet to meet the daily needs of the human body. Their lack in the body leads to the development of deficient conditions and the emergence of various diseases. But one should not go to the other extreme. There is a golden axiom in this matter: a lot - does not mean good. Excessive intake of biologically active components can harm the body no less than their lack. But it can be reassured by the fact that
an excess of vitamins with food is very difficult to obtain. To do this, you need to eat foods in tons.
Are pharmacy vitamins similar to natural ones?
Synthetic derivatives are another matter. 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 composition of the vitamin complex, many biologically active substances are present in quantities many times greater than their daily requirement. In addition, synthetically obtained 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 each other in structure, will have different properties and, as a result, have different functional effects. Knowing this fact, one involuntarily ponders the question: are vitamins from a pharmacy harmful to health?
Is advertising worth believing?
Pharmaceutical companies claim in advertising slogans that, taking their product exactly, we and our children will be healthy, beautiful and smart.
In Russia, the market, representing synthetic types of vitamins, is simply full of supply. And this is not accidental, since there is an increased demand for this type of medication. Russia is now experiencing a real vitamin boom, while all progressive humanity has questioned the benefits of pharmacy vitamins.
Shocking Vitamin Facts
To the question: “Are vitamins from a pharmacy harmful?” modern science confidently answers: the use of synthesized preparations without the presence of certain medical indications for this is not only not useful, but also capable of causing irreparable damage to health. The basis of this statement was serious scientific research involving a large number of people.
What did scientists find out?
As a result of these studies, which were conducted by European experts, 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 combination with vitamin E increases the risk of developing oncology by 10%.
- There is no natural deficiency in the body of vitamin E, but its slightest excess causes fatigue, headache, impaired vision and muscle atony.
- There was also 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: this is neuropathy, loss of sensitivity, muscle atony.
- A daily intake of 20 mg of synthetic beta-carotene increases the likelihood of acute cardiovascular failure by 13%, lung cancer - by 18%.
- Increased doses when taking vitamin C lead to a 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.
- Excessive intake of vitamins of the fat-soluble group (E, A, D, K) leads to allergies, migraines and the formation of kidney stones.
- An excess of vitamin PP leads to disruption of the digestive tract, exacerbates the course of bronchial asthma, increases the content of uric acid in the blood.
- Vitamin A hypervitaminosis 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 activate herpes.
- An overdose of vitamin B 2 causes dermatitis and numbness.
- Busting with vitamin E leads to an increased risk of thrombosis and increased pressure, impaired bowel function with diarrhea and dysbiosis.
- Excess vitamin B 12 will manifest itself in heavy rashes on the skin.
- Folic acid, taken without measure, provokes allergies, disruption of the digestive tract, serious sleep disturbances.
- Excess vitamin B 15 provokes arterial hypertension.
- Excessive doses of vitamin D can cause irritability, indigestion, unquenchable thirst, weakness, rapid urination, and calcium deposits in the vessels of the whole body.
After reading these conclusions of scientists, doubts about whether vitamins of synthetic production are harmful should be completely dispelled. However, their industrial production is not decreasing, as well as demand. Do not become a victim of annoying marketing, you need to seriously think about the health of your family.
What vitamins are better for humans?
Scientists say that the needs for vitamins for each person are individual and it is impossible to satisfy them with one, especially artificially created drug. The unique structure of natural biologically active compounds and their combination is simply impossible to repeat in a synthetic way.
The conclusion suggests itself: the best vitamins for the human body are found in foods that nature itself generously provides to us. Biologically active substances in natural products are always accompanied by a whole group of active components that 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 humans is food. The vitamins contained in it are familiar to the body and are absorbed completely without harm to it.
The value of vitamins in human life
The role of vitamins in human life is very great. These microscopic structures regulate all vital processes at the cellular level. As a result, the normal mechanism of formation of all structural components and the regulation of metabolism are implemented.
The functions of vitamins in the human body
Each of them performs its special function in the body:
- Vitamin A (acceleroftol, retinol) is responsible for growth, skin condition and human immunity.
- Vitamin B 1 regulates the functioning of muscles, central and peripheral nervous system, is a component 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 metabolism of proteins, fats and carbohydrates, and supports vision.
- Vitamin B 3 (pantothene) is involved in the general process of metabolism, is a part of digesting enzymes.
- Vitamin B 6 (pyridoxine) is responsible for 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 metabolism of fats and carbohydrates, and regulates the digestive and nervous systems.
- Vitamin C is responsible for strong immunity and elastic vessels, favorably affects the central nervous system, the work of the endocrine glands and is an oncoprotector.
- Vitamin D is responsible for the metabolism and absorption of calcium and phosphorus in the human body, and prevents the development of rickets.
- Vitamin E (tocopherol) is responsible for the normal functioning of the human reproductive system. Regulates protein and lipid metabolism, oxygen supply to tissues, prolongs youthfulness of all body tissues. Being a natural antioxidant, it retains 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 species there is such an individual concept as daily requirement. This amount is physiologically necessary for the human body to function properly. With a deficiency, the phenomenon of hypovitaminosis occurs, with an excess - hypervitaminosis. External vitamins often indicate which vitamins are lacking in the body: condition of hair, skin, nails, mucous membranes, as well as addiction to certain foods.
Signs of Vitamin Deficiency
The following signs will tell about the lack of certain vitamins:
- The pallor of the skin and their peeling, hair loss, decreased appetite indicate a lack of biotin.
- Weakness, anemia, dizziness and fatigue indicate a lack of vitamin B 12 .
- Frequent incidence of acute respiratory infections and acute respiratory viral infections, increased fragility of blood vessels indicates a deficiency of ascorbic acid.
- Increased nervousness and headaches can indicate a deficiency of vitamin B 6 .
- Problems with the skin in the form of cracks and rashes indicate a deficiency of vitamin B 2 ;
- Disorders of appetite and sleep, swelling and heart problems may be due to a lack of vitamin B 1 .
- Impaired vision, rashes and dry skin, decreased immunity, and deterioration of hair can occur due to a lack of retinol.
- Poor coagulation and wound healing indicate a lack of vitamin K.
- Vitamin D, a deficiency of which is expressed in increased nervous agitation and seizures, is also very important for the body.
Based on these signs, you can calculate the necessary vitamins and adjust the diet. But it is worth remembering that only a doctor can make such a diagnosis.
