These substances support the functioning of the nervous system, normalize metabolism in the body, strengthen memory, have a beneficial effect on hair, skin and nail plates, make blood vessels strong and elastic, and eliminate symptoms of mental and physical fatigue. With a deficiency of these vitamins, a person becomes irritable, suffers from chronic fatigue, and develops neurological pathologies and metabolic disorders.

B vitamins are essential for the human body. They support the functioning of the nervous system and brain, improve thinking abilities, participate in hematopoiesis, and regulate metabolism. A deficiency of these substances in the body causes the development of various serious diseases. Fortunately, hypovitaminosis today is easy to overcome with the help of pharmaceuticals. People of all ages are advised to periodically take B vitamin tablets.

How do B vitamins benefit the body?

Group B includes the following beneficial compounds:

• B 1 or thiamine;
• B 2 or riboflavin;
• B 3 or nicotinic acid;
• B 4 or choline;
• B 5 or pantothenic acid;
• B 6 or pyridoxine;
• B 7 or biotin;
• B 8 or inositol;
• B 9 or folic acid;
• B 10 or para-aminobenzoic acid;
• B 12 or cyanocobalamin.

Of the above vitamins, the most necessary for the body are B 1, B 2, B 6 and B 12. They should be taken periodically in tablets. A person needs other substances in small quantities, so they enter the body in abundance along with food. The main symptom of a lack of B vitamins is chronic fatigue syndrome. In this regard, multivitamins based on group B are recommended to be used in the following cases:

• under high intellectual and mental stress;
• with constant stress;
• for diseases of the nervous system;
• for disorders of the functioning of the heart and circulatory system;
• for any chronic pathologies;
• for skin diseases;
• for disorders of the digestive tract.

The main function of B vitamins is to provide the body with energy. It is these substances that play a major role in the formation of glucose from carbohydrates and the metabolism of proteins and lipids. Group B is quite unstable, the compounds are not able to accumulate in tissues, quickly leave the body, and in the current realities it is not always possible to eat a nutritious and varied diet. Therefore, both adults and children are periodically recommended to take vitamin complexes.

Typically, doctors prescribe B vitamins to patients either in injection solutions or tablets. Tablets are more convenient to use than injections. In addition, many people do not like to take vitamin injections because they are quite painful.

Which vitamin complexes for children contain B vitamins?

For children, B vitamins can be purchased not only in tablets, but also in syrup. The best children's vitamin preparations: Pikovit, Multi-tabs Malysh, Adivit.

B vitamins should be taken correctly so that they are absorbed well in the digestive tract. The medications should be taken at the same time of day. You need to take the tablets with water; you should not drink anything too hot or cold. Vitamins can cause an allergic reaction, so you should carefully look at the instructions to see how many tablets make up the daily dose and how long the intake should last.

We get B vitamins from food: cereals, vegetables and fruits, herbs, milk and eggs. If there is not enough of them in food, we compensate for the lack with vitamin tablets from the pharmacy.

But there are times when emergency “vitamin help” is needed, when it is necessary for the drug to be absorbed as much as possible. In this case, help will be provided by B vitamins in injection ampoules.

Some of the products contain only one of the vitamins, some contain a complex of them. Consult your doctor and choose which ones can help you.

The modern lifestyle of many people is closely tied to alcohol, tobacco and unhealthy diet. For this reason, the average person is deficient in B vitamins.

It is these vitamins that are responsible for good mental well-being, beautiful hair, skin condition and much more. Synthetic analogues of group B are used for medical purposes.

Beneficial properties of B vitamins

Group B includes 8 vitamins (B1, B2, B3, B5, B6, B7, B9, B12) and 9 vitamin-like compounds (B4, B8, B10, B11, B13, B14, B15, B16, B17). Most of these substances can be synthesized by human intestinal microflora, including B12.

In their natural form, vitamins are safe and an overdose never occurs. The excess substance is removed from the body and does not cause harm. In food, the vitamin is always supplemented with a set of necessary proteins and microelements - it does not need to take them from the body.

B vitamins - indications for use

Medicine is ambivalent about the use of vitamin complexes and synthetic vitamins in general. Vitamins are not harmless substances and can cause irreparable damage to health.

Situations in which it is advisable to use specific substances or a vitamin complex:

1. Sports and increased physical activity;
2. Difficult working or living conditions;
3. Medical indications:
   • hypovitaminosis;
   • cardiovascular system (ischemia, hypertension, atherosclerosis, etc.);
   • diseases of the nervous system (headaches, speech impairment, depression, stress, signs of schizophrenia, etc.);
   • diseases of the digestive system (gastritis, cirrhosis, colitis, pancreatitis);
   • metabolic disorders;
   • diseases of the visual organs (day blindness, cataracts, infections)
   • metabolic disorders and hormonal imbalances;
   • non-healing wounds and ulcers;
   • skin diseases (dermatitis, psoriasis, eczema, seborrhea).
4. Cosmetic purposes (strengthening hair, nails, skin care)

Contraindications and harm from use

A number of diseases are associated with a lack of certain vitamins in the human body (scurvy, polyneuritis, pellagra, rickets, paresthesia, etc.). Some vitamins may prevent cancer.

In order to prevent vitamin deficiency, synthetic vitamins have become widely used. Statistics on the use of these drugs have accumulated.

Studies conducted on large experimental groups of people and animals yielded results that dramatically changed the attitude of medicine towards the mass introduction of vitamin complexes for the worse.

Negative properties of synthetic vitamins of all groups were discovered:

• the ability to cause hypervitaminosis (various signs of poisoning, there is a possibility of death);
• hormonal imbalances occur;
• mortality increases (the reasons are not always clear);
• autoimmune reactions are possible;
• Various processes at the cellular level are disrupted (complications during pregnancy, cancer, etc.).

The balance of multivitamin complexes is only an advertising statement by the manufacturer. Only natural sources of microelements and vitamins will not harm your health. A complete synthesis of a natural element is an expensive and pointless pleasure.

Note! Artificial vitamins only partially imitate natural substances (there are exceptions). Modern synthesized vitamins are medicines that are used for their intended purpose.

The safety of such a product depends on the degree of purification of the final product, because aggressive substances are used in the synthesis (sulfuric acid, etc.).

In addition to individual intolerance, there are contraindications for synthetic drugs:

1. B1 – organic brain damage, menopause in women;
2. B2 – absent;
3. B3 – in the form of injections (constant high blood pressure, angina pectoris, atherosclerosis), peptic ulcer, gout, steatosis (obesity) of the liver;
4. B5 – absent;
5. B6 – ischemia, peptic ulcer, liver problems;
6. B7 – pregnancy and breastfeeding period;
7. B9 – malignant anemia;
8. B12 – chronic leukemia, angina pectoris, elevated levels of red blood cells and hemoglobin, pregnancy and breastfeeding, high blood clotting (risk of vascular blockage);

How to take vitamins correctly?

In ampoules

Injections are necessary in different situations:

1. the absorption properties of the intestine are impaired - tablets, syrup, etc. will not get into the blood. The exception is tablets that dissolve under the tongue.
2. healing period after gastrointestinal surgery;

There are a few things you need to know:

• determine the lack of specific vitamins through a blood test;
• find out the daily dose of the drug to avoid poisoning (for medical reasons, the dose may be increased);
• you should not inject the entire group B in a row at the same time,
• Pharmacologically incompatible vitamins are sometimes produced in the form of a complex (for example: B1-B6-B12) - perhaps the composition contains substances that solve this problem;
• The duration of the course is 1 or 2 weeks;
• the injection is given intramuscularly in the upper thigh or buttock;
• strictly required:
• squeeze out all the air from the syringe;
• only disposable needles are needed - the point becomes dull after the first use, with repeated insertion the subcutaneous tissues are injured and seals are formed, which will then be impossible to get rid of;
• the injection area is treated with alcohol.

In liquid form, vitamins are added to shampoos and hair masks. One ampoule per 200 milliliters is added to the shampoo. B vitamins are highly soluble in water, so the composition of the shampoo will be uniform and its cleaning properties will not change in any way.

B3 is often used for hair growth, as it increases blood circulation and awakens hair follicles, but this is more of a side effect. The contents of the ampoule are rubbed into the scalp.

B3 helps deliver microelements and nutrition to the bulbs. If hair falls out for an unknown reason (hormonal imbalances, toxins), then B3 can increase hair loss. Pantothenic acid (B5) directly affects hair growth.

In tablets

It is more natural to consume vitamins in their natural form through the digestive system. The lack of vitamin B can be compensated for by proper nutrition. There is no need to take synthetic multivitamins under normal circumstances.

If the need arises, then:

• renatured (return of natural qualities) preparations obtained from natural raw materials (vegetables, fruits, herbs, berries) or by fermentation with probiotics are preferable;
• tablets/granules/syrup are usually taken after meals to improve absorption;
• More does not mean better - an overdose provokes a lack of a number of microelements and vitamins, which is expressed in the form of allergies and side effects.
• group B cannot be mixed with vitamins C, D, K, A;
• Group B should not be mixed with each other (especially B12), with the exception of the combinations B6-B9, B12-B9, B2-B6.

Cost of the drug

Synthesized vitamin substitutes are affordable. Elite natural vitamins (New Chapter, MegaFood, SunWarrior, IHerb) are very expensive and not all pharmacies have them.

• red meat – it contains all 8 vitamins and some vitamin-like substances;
• tuna – only B5 and B7 are missing;
• beef liver – no only B7.

The simplest foods contain all group B and other nutrients necessary for the body:

1. rye, whole grain or bran bread;
2. eggs and dairy products;
3. nuts and legumes;
4. meat (including internal organs), poultry, fish (caviar);
5. buckwheat and oatmeal, brown rice (unpolished and unrefined);
6. potatoes, turnips, beets, carrots, cabbage, sorrel, lettuce, cilantro, green onions, apples, strawberries, bananas;

Separately, we can mention flaxseed porridge made from raw seeds. It contains many micro- and macroelements, including B3, B12, B6, B1.

Let's celebrate! Under normal living conditions, there is no need to take B vitamins. Proper nutrition and a healthy lifestyle - without alcohol and tobacco - provide the body with these substances in sufficient quantities. You should not independently resort to synthetic vitamin substitutes for oral administration - these are medications that are prescribed for medical reasons.
