The human body all year round needs to maintain a good condition, both physical and mental. An important factor in this matter is enrichment with vitamins. The most important group of which are B vitamins.
However, often with the wrong dosage of a particular drug, there is a risk of hypervitaminosis (excessive content of vitamins in the body). About what this will lead to and how to recognize hypervitaminosis - in detail in this article. It also offers information on the daily dose of B vitamins.
What is hypervitaminosis: its dangers
Hypervitaminosis is an excess of one or another group of vitamins in the human body. Such a diagnosis can lead not only to organ damage, but also to poisoning. The main reason for the increased amount of certain substances in the blood, according to experts, is their uncontrolled intake.
Many believe thathypervitaminosis can be obtained even while taking a product saturated with this substance. It's not!
According to statistics, an overdose of B vitamins is diagnosed in 70% of cases in children under 7 years of age. This is because parents are trying hard to improve the immune system of the baby. In addition, most of the vitamins in excess in the body are not accompanied by pronounced symptoms of hypervitaminosis.
B vitamins
B vitamins belong to the water-soluble group. They were first mentioned in 1912. At that time, they were not separated, considering them to be a single substance. As it became clear a little later, this group contained many substances that were enriched with nitrogen. Each of them had a certain effect on the body and was designated from B1 to B20.
After multiple studies by scientists, it turned out that the vast majority of B vitamins are produced by the body itself. So, the amount of these substances was noticeably reduced.
Today, an overdose of B vitamins is not uncommon. Therefore, it is extremely important to know which substance affects which organ system. So:
- B1 or thiamine is responsible for all types of metabolism in the human body.
- In 2or riboflavin also takes an active part in metabolic processes, and also improves the functioning of the visual apparatus. It has a beneficial effect on the condition of the dermis.
- B3 or nicotinic acid has a positive effect on the functioning of the nervous system andregulates metabolism.
- Vitamin B6. What is it for? This vitamin or pyridoxine is responsible for the full functioning of the nervous system, improves the functioning of the immune system and stimulates the synthesis of hemoglobin.
- B7 responsible for saturating the body with energy reserves.
- B9, which is also called folic acid - one of the most important elements among the B vitamins, which is responsible for the development of the fetus during pregnancy. It helps build immunity and the nervous system.
- B12 or cyanocobalamin is responsible for the synthesis of red blood cells, the full functioning of the central nervous system in the human body. “What is vitamin B12 for” is a simple question, it is responsible for the formation of blood cells, having a beneficial effect on the state of a person’s hemoglobin level.
Types of hypervitaminosis
Overdose of B vitamins can be either acute or chronic. The first of these occurs when a person once loads the body with a dose of a substance that is much higher than the recommended one.
Chronic hypervitaminosis appears after long-term intake of vitamins in the wrong dose. Most often, an overdose of this nature is observed in the elderly, pregnant and lactating mothers, as well as children. And it is dangerous for the body.

So, for pregnant and lactating mothers, as well as children, a prophylactic dose will be prescribed. For people leading an active lifestyle, it will be slightly higher. For those diagnosed with hypovitaminosis, an individual therapeutic dose of the substance will be selected.

If the patient is taken to a medical facility, he must be given the necessary assistance. So, first of all, he is prescribed a strict diet, which provides for the complete absence of products containing B vitamins. It is also recommended that the victim take isotonic solutions. Often this is plain sodium chloride or Ringer's solution. Further, specialists prescribe diuretics to speed up the process of cleansing the body from a toxic dose of substances.

He, in turn, depending on the severity can lead to kidney failure, blood clots, impaired lung function and even anaphylactic shock.
Do you need to take B vitamins
In our country it is customary to drink vitamin complexes twice a year. Allegedly, in the spring and in the autumn-winter period, the body is weakest and needs additional nutrition. All this is nothing more than fiction. Moreover, B vitamins are found in almost all foods that we consume daily.
The most typical deficiency for our human body is the lack of vitamin D, as well as iodine, zinc and magnesium. To replenish their amount in the blood, you need to consult a doctor and take each substance separately according to a special scheme, and not load the body with a complex of substances that you may not need to take at all.
Also, do not forget that in order to diagnose hypo- or hypervitaminosis, you need to undergo a complete medical examination. After that, you will be able to understand exactly what your he alth lacks and what should be taken extra. Prevention of hypervitaminosis should not be carried out without the supervision of a doctor.
Scientists have not proven the fact that the body needs complex drugs just "in reserve" and to strengthen the immune system. They are of the opinion that taking certain substances is advisable only if their deficiency is detected.
