Even if your city is not a huge metropolis, the urban lifestyle cannot be canceled. An abundance of technology, long hours at work, and stress have a negative impact on health. The B complex of vitamins is a storehouse that will compensate for the lack of nutrients in the body. Health, beauty, proper metabolism and energy exchange are based on these elements. Find out about the need for specific foods in the diet and a complex of drugs containing B vitamins in the body, as well as problems with their deficiency.

Benefits of B vitamins

You've definitely already heard about the enormous benefits of the complex of this group of vitamins. Each element performs its own function, which is responsible for vital processes. They cannot replace each other in combination, so a lack of one type of vitamin leads to the destruction of the entire system. The group has 6 components included in many metabolic mechanisms. Let's take a closer look at each element of the complex and the daily norm.

B1 known as “thiamine” or “thiamine pyrophosphate”. The vitamin takes part in the metabolism of fats, salts, carbohydrates, and proteins in the body. The main element of the system - the brain - functions fully only when it is provided with thiamine. Vitamin B1 is responsible for normalizing the digestive system and stimulating appetite, which leads to increased productivity. The daily intake of the substance for an adult is 1.3 mg, for pregnant women - 1.6 mg, for children under 3 years old - 0.8 mg. A lack of thiamine leads to disruption of coordination, sleep, calmness, and endurance of your nervous system.

Riboflavin (B2) responsible for normalizing energy reactions. The main processes occurring with the help of this vitamin are the development, creation, regeneration of body tissues, the combination of antibodies and blood cells. The level of riboflavin B2 in the body contributes to the coordinated functioning of the skeleton, muscles, immunity, digestive system and hematopoiesis. It is necessary for hair, skin, and nails, so if there is a lack of vitamin, they deteriorate (characterized by brittleness and lethargy). The daily norm for adults is 1.2 mg, for a child 4 years old – 0.6 mg, for pregnant women – 1.6 mg.

Nicotinic acid, vitamin PP or B3– guarding the epidermis. Its job is to stimulate skin respiration. Nicotinic acid regulates blood circulation, normalizes blood vessel processes, lowers cholesterol levels and protects against atherosclerosis. In group B, the nicotine vitamin prevents the development of pellagra. The daily norm of nicotinic acid for an adult is 15 mg, for a 5-year-old child – 8 mg, for a pregnant woman – 18 mg.

Pantothenic acid, or B5, is responsible for the normal tone of muscle tissue, body thermoregulation, and heart function. The vitamin participates in the synthesis of adrenal hormones and blood antibodies, protecting the body from infectious diseases, toxic substances and cancer. A deficiency of B5 causes dizziness, nausea, headaches, and insomnia. The daily requirement of the vitamin for an adult is 6 mg per day, for a 5-year-old child – 4 mg, for a pregnant woman – 8 mg.

Pyridoxine, or B6, is involved in the connecting reactions of amino acids in the body. The vitamin helps produce enzymes and hormones, break down fats, lowering cholesterol levels. A lack of pyridoxine can lead to anemia and regression of the cardiovascular system. If there is a lack of vitamin B6 in your body, it will easily lead to dermatitis, depression, nausea, vomiting, and deterioration of skin tissues. The daily norm for an adult is 2.1 mg, for a child 5 years old – 1.2 mg, for a pregnant woman – 2.5 mg.

Folic acid, or B9, – is extremely necessary during pregnancy. The vitamin is responsible for the creation of a normal nervous system, blood circulation, and timely growth of the fetus. If the body has enough folic acid, then menstruation in adolescents is painless, menopause in women is without complications, and in pregnant women the risk of premature birth is minimized. Hypovitaminosis B9 leads to anemia, leukemia, irritability, apathy, and insomnia. The daily norm of folic acid for adults and children is 0.2 mg, for pregnant and lactating girls - 0.3 mg.

Cyanocobalamin, or B12, is important in the processes of creating red blood cells and synthesizing hemoglobin. The vitamin promotes the production of antibodies in the body that resist viruses and infections. The course of processes in the male reproductive system requires B12 elements. The daily vitamin requirement for an adult is from 3 mcg, for children 5 years old – 1.6 mcg, for pregnant women – 4 mcg.

Intravenous - only to a nurse if you or family members do not have appropriate medical education.

• Observe yourself for several days: monitor your well-being, the condition of your skin and hair, your appetite; analyze your diet.

• Find a suitable complex in our article and be healthy!

Before the formula was figured out, vitamins were called letters of the Latin alphabet as they were discovered: A, B, C, D, and so on. Now they have rational names based on their chemical structure. Vitamin A is retinol, vitamin K is phylloquinone, vitamin B2 is riboflavin, vitamin PP is nicotinic acid, etc. But in the old fashioned way we call them “A”, “Be” and “Tse”... How could it be otherwise, after all? vitamins are our old friends! But how well do we know them?

They say that every doctor has his own “favorite” drugs. This is true. The doctor knows some medications better, prescribes them first and sometimes takes them himself. And each doctor has his own favorite vitamins, which he will most likely recommend to you.

But then we come to the pharmacy - and our eyes widen. They offer a sea of ​​vitamins in beautiful jars with bright labels! Entire shelves are occupied by them. But the doctor insisted on one single drug... Isn’t it better to buy THIS and THAT? Maybe the doctor hasn’t looked at the reference books for a long time? And the hand reaches out to the magic pills that catch your fancy.

But, wait, let's remember what the doctor advised. Do you know which vitamins doctors love especially dearly? Of course, B vitamins.

The thing is that great hopes were placed on them in the eighties of the last century: it was believed that B vitamins reduce the level of homocysteine ​​in the blood - an amino acid, the high level of which is directly related to heart and vascular diseases. Many studies have been conducted in different countries, and as a result, the effectiveness of these vitamins was considered ambiguous: “50 to 50.” Indeed, when patients take more effective medications, “vitamins” play only a supporting role. But doctors continue to prescribe them for various cerebrovascular pathologies (diseases of the blood vessels of the brain). Additional help for the body is not a hindrance, right?

Yes, modern, effective and inaccessible to most patients due to their high price, drugs act much faster. And of course, “vitamin therapy” is not so effective. But almost all drugs have a “dose-dependent” (the higher the dosage, the better) and a “chrono-dependent” (the longer the drug is taken, the longer the positive dynamics persist) effect.

At the same time, the undeniable advantage of vitamins is the price. When prescribing a drug, a doctor can be sure that the medicine will be taken as long as needed and will not empty the patient’s wallet. Many doctors, when prescribing group B, focus on this.

Get to know everyone by sight

You know the basic B vitamins for sure. These are the well-known B1, B6 and B12:

• IN 1– (thiamine) actively participates in metabolism, restores peripheral nerve endings that regulate the functioning of the liver and heart.
• AT 6– (pyridoxine) strengthens the immune system, has a beneficial effect on skin diseases, and restores the nervous system. According to some data, 80 mg of vitamin B6 per day reduces the risk of myocardial infarction by 32%.
• AT 12– (cyanocobalamin) has a beneficial effect on the function of the liver and nervous system, and is involved in the restoration of metabolism. Vitamin B12 is effective in treating chronic fatigue syndrome in 50–80% of people.

But their less famous brothers deserve attention too.

• AT 2– (riboflavin) participates in metabolism, strengthens the respiratory system, improves vision, cures skin diseases, and has a beneficial effect on the functioning of the nervous system.
• AT 3– (nicotinic acid) cures pellagra, improves water-salt metabolism, improves metabolism in nervous tissue cells.
• AT 9– (folic acid, folacin, vitamin Bc) is extremely important for the development of the brain and nervous system of the fetus, it is also needed for the development of a breastfed child, and for adults, primarily for the normal functioning of the nervous system.

Do you get the general idea? Right! B vitamins are essential for diseases of the nervous system. Which of us has “nerves” in order? Now my head hurts, now my irritability has increased, now my back is “shot”, now I have problems with my memory...

B vitamins are called “neurotropic” because of their effect on the function of nerve cells. Some studies have shown high activity of this group in terms of pain relief in chronic pain syndromes and increasing the pain threshold in acute pain. Currently, more than a hundred studies have been published showing clinical improvement with the use of B vitamins in patients with pain syndromes.

Vitamins of this group are especially often prescribed to patients with back pain. Once you see a doctor with the complaint of “your back is stuck,” “shot in the air,” or “arm/leg is numb,” a prescription with the treasured trinity (B1+B6+B12) will be in your hands. Why? Because it has been repeatedly proven that it is these “magic” vitamins that influence nerve cells coming from sensitive receptors to the brain, as if “inhibiting” pain impulses.

If the nerve fiber itself, consisting of hundreds and thousands of processes of neurons (nerve cells), is damaged, then their successful “restoration” requires the same vitamins that work, laying proteins like bricks to recreate the fiber shell.

However, many neurologists remain skeptical about their therapeutic potential, believing that in many cases there is a placebo effect. The fact is that no one has ever been able to achieve a 100% effect in treatment when prescribing vitamins alone. Therefore, if you have back pain, consult a doctor, he will select the right combination of medications for you, including the B-complex.

In 2000 and 2002, the American Psychiatric Association published research in the American Journal of Psychiatry showing the effect of vitamin B12 deficiency on the occurrence of clinical depression in elderly patients. For many of them, antidepressants were not indicated, so vitamin complexes paired with diet and exercise gave good results. Given these data, many doctors began to actively prescribe B-complexes for the treatment of depression and achieve results.

Other studies have shown that pregnant women consuming foods rich in folic acid or taking adequate doses of folic acid and vitamin B12 significantly reduce the risk of developing neural tube defects. This is also the “gold standard” of pregnancy management throughout the world.

B1 deficiency also plays a big role in the development of alcoholic polyneuropathy, which in Russia is one of the most common forms of generalized damage to peripheral nerves.

The only questionable purpose of this group is still asthenic conditions, such as the notorious “chronic fatigue syndrome”. Too many diseases can be hidden under the guise of this seemingly innocent diagnosis. The man is tired... stress, lack of sleep and irregular nutrition have taken their toll. Take some vitamins and everything will go away? And they drink! Handfuls and kilograms!

When consuming excessive doses (three or more times the recommended daily intake) of B vitamins, intoxication develops. Hypervitaminosis of vitamins B1, B2 and B6 can cause fatty liver. Among the elements of group B, the most toxic are B6 and B12. And allergic reactions are observed mainly with their excess, as well as with an overdose of vitamins B1 and B2.

Thus, an excess of vitamin B1 causes symptoms in the form of allergic reactions and spasmodic headaches. Blood pressure decreases, fever, weakness, nausea appear, vomiting may occur, chills are replaced by a feeling of heat, tinnitus bothers you, severe sweating and dizziness appear.

With prolonged use of vitamin B6 in excess dosages, anemia develops, coordination of movements is impaired and numbness of the limbs appears.

Excess vitamin B12 leads to heart failure, pulmonary edema, vascular thrombosis due to increased blood clotting and anaphylactic shock. The heartbeat quickens, pain appears in the heart area, nervous disorders intensify, and allergic rashes appear on the skin in the form of hives.

As you can see, caution is needed even with such seemingly harmless drugs as vitamins. Therefore, it is best to consult a doctor for advice. And he will definitely tell you everything he knows about his “favorite” vitamins.

B vitamins are a class of low molecular weight compounds involved in the metabolic processes of animal cells. Substances act as catalysts in the synthesis of proteins from amino acids, hormones, and nucleins. Some of the representatives of the group are no longer classified by science as , B13). Such vitamin-like substances are synthesized by the intestinal microbiota or replaced by structural analogues without compromising metabolism.

Essential vitamins must come from outside, so you need to know which foods contain vitamin B. The body needs these compounds in ultra-small doses, since they do not provide energy or nutritional value. Therefore, the desire to eat only foods rich in vitamins is wrong. A normal diet contains a sufficient amount of bioactive compounds, and the excess is not retained in the body and is excreted in the urine. However, for diseases that are accompanied by hypovitaminosis, a diet high in vitamins or injections of dosage forms are required.

The B group of vitamins is produced by plants, yeasts, and lactic acid bacteria. Therefore, a class of these substances is found in vegetables, dairy products, grains, mushrooms, fruits, and nuts. The source is muscle tissue and animal organs.

When choosing a diet, you need to take into account that vitamin B is destroyed during heat treatment:

• B1 is lost by 50% during metabolism;
• B2 is lost up to half during cooking, and a tenth during stewing;
• B3 is washed out when food is boiled;
• B9 is destroyed by heat treatment.

Heat resistant B6 and B12. Other representatives can withstand short-term heating not exceeding 100°C. It is better to steam the products, simmer them over low heat, or eat them raw.

Characteristics of B vitamins, properties and where they are found

Coenzymes are necessary for the body to convert nutrients into energy and building material for cell growth and renewal. This is why vitamin B serves as a leading factor in the absorption of carbohydrates, fats and amino acids.

It is necessary to accept that vitamin B is responsible for metabolic processes as a whole, and not individually. The subgroup affects the development of nervous tissue, cell division of the embryo, the functioning of the liver, and organs of vision.

The benefits of vitamins can be understood by the symptoms of a lack of these substances:

• nervous exhaustion;
• depression or apathy;
• fatigue;
• memory impairment;
• low concentration;
• amyotrophy;
• headache;
• hormonal disorders.

With an irregular diet, avoiding meat products, milk and bread, it occurs. A deficiency can begin against the background of an intestinal disorder, when the natural microbiota cannot cope with synthesis.

In a healthy person, the daily requirement of B vitamins is covered by food intake. A dose of 2⋅10-4 g is sufficient for the body. Health status, exercise level and age affect the need for B vitamins.

Table of daily human needs for group vitamins

Attention: The internal data of table “57” is corrupted!

With increased mental stress and physical activity, it is allowed to exceed the norm by two times. During exhaustion after fasting, vegetarian diets, protracted illnesses, injections of dosage forms of vitamins are required.

B1 (thiamine)

Thiamine diphosphate is a substance responsible for the functioning of the nervous system and cognitive functions. Participates in the formation of metabolites that prevent fatigue and stress. Thiamine catalyzes the biosynthesis of neuronal mediators that affect memory and concentration. Without B1, the absorption of proteins, carbohydrates and fatty acids is difficult. Present in cell plasma, necessary for the synthesis of ATP in mitochondria. Deficiency is accompanied by chronic fatigue syndrome, depression, disorders of brain activity, heart function and digestion.

Which foods contain more vitamins:

• baker's and brewer's yeast;
• cereals, nuts, cereals;
• wholemeal bread;
• dried fruits;
• legumes;
• onions, greens;
• cabbage;
• whole milk;
• eggs.

The main sources of thiamine are plant foods. Cooking reduces the concentration of the vitamin by half, so it is useful to eat raw vegetables, herbs and fruits. The microflora of the colon of a healthy person can independently create B1 or structural analogues.

Nicotine sulfate is a thiamine antagonist, so smokers should get more of the vitamin from food or switch to other means of delivering nicotine. Ethanol, coffee and sugars impair the absorption of B1.

B2 (riboflavin)

Riboflavin is actively involved in the division of nerve cells, maintaining hematopoietic functions, and the synthesis of hemoglobin from iron. B2 controls the secretion of adrenal glands and substances that protect the fundus.

With a lack of riboflavin, twilight and peripheral vision decreases, the immune system is weakened, and diseases of the skin and mucous membranes occur. Due to suppression of the production of adrenal hormones, children lag behind in growth and development.

Where is riboflavin found and which foods contain more vitamin:

• red meat;
• Fish and seafood;
• egg white;
• fermented milk products and cheeses;
• wheat, oats, buckwheat;
• leaf salad.

The body receives riboflavin from animal foods and produces it independently in the lower intestines. Plants contain an incomplete analogue that cannot fully replace B2. Therefore, a strict plant-based diet and vegetarianism are harmful to health.

Therapeutic forms are prescribed for diseases of the liver, eyes, skin rashes, chronic or severe infections and food poisoning.

B3 (niacin, niacin, PP)

Nicotinic acid is a product of nicotine oxidation. In the body it is transformed into nicotinamide, which triggers the metabolism of lipids, proteins, and tissue respiration. Niacin regulates cholesterol levels, improves blood circulation in the brain, and accelerates the removal of toxins. PP normalizes hormonal balance, affects sexual functions and sugar levels.

In the human body, PP is formed during the absorption of tryptophan or comes from the outside. Hypovitaminosis leads to sleep disturbances, signs of anemia, dystrophy, fatigue and memory loss occur.

• poultry, veal, beef;
• sea ​​fish;
• eggs;
• garlic;
• Bell pepper;
• mushrooms;
• greenery.

The main source of niacin is animal food. Preference should be given to lean meat, beef or chicken liver and salmon fish. Niacin precursors are found in red and black caviar, hard cheese, and nuts. With a vegetarian diet, it is worth consuming more soybeans, sunflower seeds, almonds, and pine nuts.

B4 (choline)

Choline is not a vitamin. A healthy body does not need additional sources of this substance. The human body carries out synthesis in the liver and intestines.

The vitamin-like compound is involved in the synthesis of neurotransmitters in the nervous system, protects the liver, regulates insulin levels in the blood, and helps fight depression.

With hepatitis and cirrhosis, the biosynthesis of choline is disrupted, which leads to hypovitaminosis, fatty liver, and impaired protein metabolism. Lack of a substance in food affects sexual impotence, weight problems, mental abilities and mood. To eliminate B4 deficiency, you need to know what the vitamin contains:

• eggs;
• legumes;
• dairy products;
• porridge;
• fish;
• cabbage.

To maintain the body's production of choline, you need to avoid alcohol, fatty foods, and take phospholipids and hepatoprotectors.

B5 (pantothenic acid)

Panthenol is important for the regeneration of tissues and organs, blood renewal, production of hormones and immune agents. Pantothenic acid is found in plant and animal foods, but is not preserved during heat treatment. Normally, a sufficient amount of vitamin is produced by symbiotic bacteria. An organism weakened by disease needs additional sources of panthenol.

What foods contain vitamin B5:

• hazelnuts;
• dairy products;
• fresh vegetables and herbs;
• Champignon;
• beer;
• garlic;
• buckwheat and oatmeal.

Panthenol of animal origin is found in offal - kidneys, heart, liver, tongue.

Deficiency leads to hair loss, brittle nails, skin problems, metabolic disorders, and gastritis. Normalizing the intestinal flora will help restore natural B5 synthesis.

B6 (pyridoxine)

The pyridoxine group regulates the functioning of enzymes, participating in every stage of metabolism. B6 helps digest proteins and fats. The vitamin is needed for the functioning of the cardiovascular system and hormonal regulation.

Pyridoxine is responsible for the formation of mediators for the normal functioning of the nervous system and the emotional background. B6 is involved in the processes of transferring genetic information during cell division and reproduction.

Normally it is formed by the intestinal microbiota and comes with food. With dysbacteriosis and digestive disorders, a deficiency occurs that needs to be replenished with food.

• chicken meat;
• beef and veal;
• liver and heart;
• black bread;
• buckwheat grain;
• fatty fish;
• vegetables.

Children face hypovitaminosis. Lack of vitamin reduces immunity, provokes psychological disorders, and causes developmental delays in the child. In adults, hypovitaminosis occurs against the background of protracted illnesses and antibiotic use.

B7 (biotin, H)

Vitamin H or biotin interacts with digestive enzymes, helps break down fats, synthesize protein, and regulates sugar metabolism.

Deficiency develops when consuming alcohol, sugar substitutes, on the background of exhausting diets or congenital anomalies of the digestive organs. Antibiotics suppress E. coli, which are responsible for the synthesis of biotin.

A lack of vitamin H causes muscle pain, sleep disorders, increased concentrations of glucose and cholesterol, and metabolic disorders.

What foods contain vitamin B7:

• soybeans, peas, beans;
• liver and kidneys;
• peanut;
• hazelnut;
• cauliflower;
• boiled eggs;
• mushrooms.

Healthy intestinal biota independently produces the necessary vitamin B7.

B8 (inositol)

Does not apply to vitamins, there is no need for use. B8 is freely synthesized in body tissues from glucose.

A deficiency of the substance does not manifest itself and does not cause problems. Inositol is found in the membranes of the brain, blood, and eyes. Performs protective and metabolic functions.

Foods rich in B vitamins and carbohydrates serve as raw materials for the synthesis of inosine by the body itself.

B9 (folic acid, folates, glutamates)

Group B6 combines derivatives of folic and glutamic acids. It is secreted by intestinal bacteria and comes with food. Flavor enhancers E620-E624 or glutamates serve as precursors for vitamin B6.

Participates in hematopoiesis, the development of immunity, the development of the nervous system and the transmission of heredity.

The deficiency leads to pathology of gestation, impaired development of the central nervous system and gastrointestinal problems.

The greatest source of folate is fresh greens. Therefore, it is important to eat salads, onions, spinach, parsley, dill, and herbs.

Which foods contain the most vitamin B6:

• legumes;
• tomatoes;
• steamed potatoes;
• black bread;
• beet;
• kvass and beer.

During pregnancy and lactation, you need to increase the content of folic acid in food or take a dosage form of the vitamin.

B12 (cobalamins, cobamide)

B12 is a cobalt-containing vitamin produced by bacteria. In the human body they participate in hematopoiesis and control hemoglobin levels. B12 catalyzes the synthesis of myelin sheaths of neurons, immune blood factors, and normalizes liver function.

With deficiency, anemia and diseases of the digestive tract develop. Lack of vitamin B12 leads to nervous disorders and mental disorders.

Foods rich in B12 vitamins:

• liver;
• heart;
• fish and shellfish;
• meat products;
• cheeses.

The source of cyanocobalamin is food of animal origin, meat. Plants do not produce cobalamins, so vegetarians cannot get B12. Pseudovitamins in a vegan diet harm the body by disrupting the metabolism of important substances.

B17 (amygdalin or laetrile)

Amygdalin is a product of marketing and a clear example of quackery. advertised as an anti-cancer “cure”, profiting from desperate patients.

The substance is toxic; in the human body it breaks down into hydrocyanic acid and cyanide derivatives. When taken systematically, it causes poisoning and even death.

In addition to unconventional medicines, substances labeled B17 are found in processed almond products, cherry pits, bird cherry seeds, apple and plum tree seeds.

There is no confirmed scientific data on treatment with laetrile, but cases of toxicity and death during unconventional treatment are recorded.

Harmful properties of B vitamins

Vitamins do not have a negative effect on the body in physiological doses. When using dosage forms, hypervitaminosis may develop:

1. Thiamine B1 causes kidney failure, obesity and liver degeneration.
2. Pyridoxine B6 in high pharmacological doses disrupts the functioning of the nervous system.
3. Folic acid B9 causes symptoms of poisoning, digestive tract upset and heart problems.
4. Increased doses of nicotinic acid B3 provoke skin redness and liver dysfunction.

Vitamin B supplied from foods is harmless. During vitamin deficiencies, you need to follow the dosage of dosage forms and daily norms, then negative consequences can be avoided.

B vitamins are natural substances that enter the human body with food. They are extremely important for normal life. These vitamins play a special role in the functioning of the nervous system. If not enough of them enters the human body, then this in itself can lead to malfunctions in the functioning of the nervous system (in particular, to the occurrence of polyneuropathies). In addition, in a number of pathological processes in nervous tissue, B vitamins have a therapeutic effect due to their ability to influence metabolism and restore nerve fibers. That is why this group of drugs is widely used in the treatment of neurological diseases. In recent decades, B vitamins have begun to be used for problems with any part of the nervous system, because the role of their deficiency has been proven even in the development of thinking disorders. This article will focus on the main aspects of the use of B vitamins in neurological practice. You will receive information about the types of B vitamins existing on the pharmaceutical market and the features of their use.

When they talk about the effect of B vitamins on the nervous system, they usually mean the three most important of them: vitamin B 1 (thiamine), vitamin B 6 (pyridoxine) and vitamin B 12 (cyanocobalamin). These substances are essential for the functioning of our brain and nerves.

How do individual vitamins work?

For prevention purposes, it is enough to simply eat well, getting the required amount of each B vitamin from food.

B vitamins are unequal in their effects. Each of them has its own tasks, which we will talk about now.

B 1 performs the following main roles:

• ensures the processing of carbohydrates by nerve cells, maintaining energy potential;
• carries out the conduction of nerve impulses along the peripheral processes of nerve cells (axons), thus realizing impulse transmission;
• deals with the construction of nerve cell membranes;
• participates in the healing of damaged nerve processes (regeneration).

In 6 it works like this:

• participates in the synthesis and destruction of biologically active substances that are transmitters of information in the nervous system (dopamine, gamma-aminobutyric acid, serotonin and others);
• regulates protein synthesis and fat metabolism;
• ensures the transmission of impulses at the point of contact of two nerve cells (synapse);
• fights free radicals, that is, it is an antioxidant.

At 12 is needed for:

• building the myelin sheath of nerves;
• synthesis of acetylcholine (a substance through which impulses are transmitted between neurons);
• reducing pain associated with damage to nerve fibers.

Of course, these are not all the functions of B vitamins. Above is only a small part of their work, which relates specifically to the nervous system. And the role for the whole organism is much broader.

Due to such a key role of B vitamins in metabolic processes in the nervous system, they are usually called neurotropic.

Neurotropic vitamins of this group have a unique property: when used simultaneously, their effect is significantly greater than simply the sum of their individual effects. This means that simultaneous administration of all three drugs at once is much more effective than using them individually. Therefore, several decades ago, pharmaceutical companies focused their efforts on creating combined forms of B vitamins in order to improve the quality of treatment and increase the ease of use of drugs. For example, previously it was necessary to perform three different injections so that the patient could receive all three neurotropic vitamins. And today there are drugs that contain all three components in one ampoule. Agree that this is much more convenient and causes less inconvenience to the patient. The same can be said about tablet forms. B complex vitamins in the form of tablets and dragees are available in pharmacies.

Diseases of the nervous system, in the treatment of which B vitamins are used

The role of B vitamins in relation to the nervous system is considered not to be fully understood. More and more new information is coming in after various studies. And in connection with new data, the list of neurological diseases in which neurotropic vitamins have a therapeutic effect is constantly expanding. Great prospects open up for them in the future. The list of neurological problems for which B vitamins can be used consists of:

• various types of polyneuropathies (primarily and);
• neuropathies of individual nerves (traumatic, infectious and others);
• neurological complications of osteochondrosis of various parts of the spine (lumboischialgia, cervicalgia, cervicobrachialgia, thoracalgia, radicular syndromes);
• tunnel syndromes (, tarsal canal and others);
• neuropathic pain (for example, with);
• myelopathy;
• acquired mental disorders, in particular - some varieties;
• pyridoxine-associated epilepsy in children.

The therapeutic effect consists of stimulating the healing of nerve fibers and their sheaths, improving conductivity along the nerves. Due to this, the severity of motor and sensory disorders in patients decreases. In addition, in case of damage to the nervous system, the administration of vitamins of this group allows one to achieve a clear analgesic effect for neuropathic pain. Recently, the influence of B vitamins on vascular and neurodegenerative diseases has been actively studied. It has already been proven that due to a multi-stage biochemical process, B vitamins can slow down the progression of atherosclerosis and reduce the risk of thrombosis. Therefore, their use may be useful in preventing the occurrence of cerebrovascular accidents ().

I would also like to dwell on the point that many of the above diseases of the nervous system can sometimes be associated with insufficient levels of the triple B vitamins in the body. However, there are no other reasons for the occurrence of these diseases. For example, polyneuropathy can occur on its own only with a deficiency of vitamin B1 or B6, and a long-term deficiency of vitamin B12 can cause damage to the spinal cord. Research has found that a deficiency of B vitamins often occurs when:

• poor nutrition (since the human body receives the bulk of vitamins from food);
• alcohol abuse (because this usually also leads to poor nutrition, and the body requires a lot of vitamin B1 to break down alcohol);
• drug addiction (due to an antisocial lifestyle);
• disruption of absorption processes in the intestine (malabsorption syndrome, duodenal ulcer and other diseases);
• after surgical operations on the gastrointestinal tract;
• when taking a number of medications (for example, isoniazid for tuberculosis or diuretics for edema).

It is noteworthy that B vitamins exert their therapeutic effect not only in conditions of their deficiency. Due to the peculiarities of their participation in metabolism, their fairly large doses are necessary for the body to fight many diseases and in cases where there is no shortage of them.

Features of the use of B vitamins

In the pharmacy chain you can purchase each of the B vitamins separately or a mixture of them in one ampoule

B vitamins are water-soluble, which allows them to be easily absorbed when taken orally and interact with the natural environment of the body. However, vitamin B1 in small doses in the form of tablets is destroyed in the intestines by enzymes and, accordingly, is poorly absorbed. If you try to increase the dose, this generally leads to a blockade of the transfer of the vitamin from the intestines to the blood. How to be? Medicine has found a way out of the situation. Sufficient concentrations can be achieved by parenteral administration, as well as by using a fat-soluble form of vitamin B1, which can dissolve in fats. This form of vitamin B1 is called Benfotiamine. Benfotiamine is resistant to gastrointestinal enzymes, which makes it possible to absorb large doses and achieve the required concentration of the drug in the blood.

Another feature of the application is the following: individual vitamins B 1, B 6, B 12 cannot be used as a joint injection with one syringe, that is, in the form of a mixture. The fact is that these vitamins can be purchased separately at the pharmacy (ampoules of vitamin B1, ampoules of vitamin B6, ampoules of vitamin B12). In these cases, it is strictly forbidden to combine a solution from one ampoule with a solution from another in the same syringe. But given the frequent need to use these vitamins at the same time, the pharmaceutical industry has solved this problem. Mixtures of these vitamins have been synthesized, which are already mixed in one ampoule and do not inactivate each other, but on the contrary, enhance the effect. Since then, if it is necessary to use all three vitamins at the same time, only industrially prepared mixtures are prescribed. Some of them also contain lidocaine, which is an anesthetic. It is able to enhance the analgesic effect of B vitamins, as well as make the injection itself insensitive to the patient.

The next feature of the use of B vitamins is a potential allergic reaction to them. In principle, any medicinal substance may not be individually tolerated by the patient; it is impossible to predict such a reaction. But you should be more careful with vitamins B 1 and B 12. Allergies to these vitamins, although rare, do occur, so this fact must be taken into account by both medical personnel and the patient.

List of B vitamins that can be found at the pharmacy

The world of business also affects the pharmaceutical industry. Regarding B vitamins, it looks like this: the main three vitamins are represented by a huge number of drugs. That is, a variety of medicines have the same active composition. The difference lies only in the manufacturer and sometimes in additional substances, and, of course, in price. Some manufacturers claim that the effectiveness of the drug is affected by the degree of purification. We do not undertake to evaluate B vitamins according to this indicator. Let us compare them only in terms of composition and forms of release. To avoid getting into trouble and not overpaying for the same substances, we recommend that you familiarize yourself with the list of B vitamins below.

So, the most common B complex vitamins are:

• Milgamma;
• Combilipen;
• Vitaxon;
• Vitagamma;
• Binavit;
• Neurorubin;
• Neurobion;
• Compligam B;
• Trigamma.

What do all these drugs have in common? All of these medications are available in the form of solutions for intramuscular injection. 1 ampoule of any of them contains 100 mg B1, 100 mg B6 and 1 mg B12. As you can see, the active ingredients are absolutely identical both in composition and dosage. Some of the drugs additionally contain 20 mg of Lidocaine for an analgesic effect (all of the above, except Neurobion and Neurorubin). There is one more difference: Neurobion and Neurorubin contain 3 ml of solution in one ampoule, and all others contain 2 ml. However, this does not affect the total dose. That is, in order to get the same amount of mg of vitamins, you need to inject, for example, Combilipen 2 ml, and Neurorubin 3 ml.

And, of course, the price. According to this indicator, all drugs differ significantly from each other. Those produced abroad are much more expensive than domestic analogues. However, their similarity in composition and dosage allows you to choose a medicine that everyone can afford.

In addition to the release form in the form of an injection solution, all of the above drugs, except Trigamma, Vitagamma and Binavit, are also available in the form of tablets or dragees for oral use. This provides a continuous course of treatment for certain neurological conditions, which is very convenient. The composition and dosage in the case of tablet forms are much more varied than in injection forms. Let's take a closer look at this point.

Milgamma compositum (this is what the dragee is called) and Vitaxon contain a fat-soluble form of vitamin B 1 (benfotiamine) 100 mg and vitamin B 6 100 mg. Combilipen tabs contains the same amount of benfotiamine and vitamin B6 as Milgamma, but in addition also 2 mcg of vitamin B12. Neurobion consists of 100 mg of thiamine, 200 mg of pyridoxine and 200 mcg of cyanocobalamin (the manufacturer writes that each tablet contains an excess of vitamin B 12 in the form of an additional 20%, that is, only 240 mcg). Neurorubin - Forte Lactab contains 200 mg of vitamin B1 (not benfotiamine!), 50 mg of vitamin B6 and 1 mg of vitamin B12. Compligam B complex contains a whole range of B vitamins:

• 5 mg thiamine (vitamin B 1),
• 6 mg pyridoxine (vitamin B 6),
• 6 mg riboflavin (vitamin B2),
• 0.6 mg folic acid (vitamin B 9),
• 9 mcg cyanocobalamin (vitamin B 12),
• 60 mg nicotinamide (vitamin B 3),
• 15 mg pantothenic acid (vitamin B 5),
• 150 mcg biotin (vitamin B 7),
• 100 mg choline (vitamin B 4),
• 250 mg inositol (vitamin B 8),
• 100 mg para-aminobenzoic acid (vitamin B 10).

As you can see, tablet forms vary greatly in dosage and composition, which means they cannot always serve as an identical replacement for each other.

There are B vitamins that so far only come in tablet forms. Among them, Neuromultivit, Neurobex and Neurovitan are widespread. Neuromultivit is similar to Neurobion in composition. Neurobeks exists in two forms: Neo (vitamin B 1 50 mg, vitamin B 2 25 mg, vitamin B 6 10 mg, vitamin B 5 25 mg, vitamin B 9 0.5 mg, vitamin B 12 5 mcg, vitamin B 3 100 mg, vitamin C 175 mg) and Forte (vitamin B 1,100 mg, vitamin B 6,200 mg, vitamin B 12,300 mcg). Neurovitan has an interesting composition: octothiamine 25 mg (this is thiamine + thioctic acid, which is an antioxidant), riboflavin 2.5 mg, pyridoxine 40 mg and cyanocobalamin 0.25 mg. It is possible that soon manufacturers of only tablet forms will begin to produce injectable forms, since often the treatment process first requires parenteral administration of vitamins.

I would like to note the fact that the B vitamins in these preparations are medicines. They cannot be taken independently and uncontrollably, carelessly thinking that they are just vitamins. Yes, these are vitamins, but in medicinal dosages, so only a doctor should prescribe them.

From all of the above, it turns out that the arsenal of B vitamins for combating the pathology of the nervous system is very wide. Currently, the attending physician has the opportunity to choose a drug based on dosage and price category, which is a definite plus. And given the emerging new information about the role of B vitamins in the functioning of the nervous system, it can be assumed that the list of these drugs will soon be replenished with new drugs with different dosages and composition.
