Why vitamins b6 v5. Vitamin B6 - what does the body need it for. Three foods that are very rich in vitamin B6

To maintain vital functions, vitamin B6 is needed by the body of both men and women. It helps with stress, depression, fatigue, disorders of the heart and joints.

Pyridoxine (as B6 is also called) is a water-soluble substance that remains resistant to high temperatures and is rapidly excreted from the body, but is destroyed when exposed to sunlight. Since this B vitamin is extremely beneficial for health, it is necessary to maintain its level within the normal range.

The role of pyridoxine (vitamin B6) for the human body

The main role of B6 is participation in the metabolic processes of amino acids. It is from them that proteins are composed, which are so important for normal human life.

If we take a closer look at vitamin B6 and why the body needs it, we can say that it is involved in the functioning of almost all organs and systems:

• promotes the breakdown of fats, helping to fight excess weight;
• participates in the production of serotonin, which improves mood and relieves stress and depression;
• normalizes blood sugar levels, providing prevention of diabetes mellitus;
• restores arterial pressure, prevents the formation of blood clots;
• normalizes cholesterol levels, reduces the likelihood of developing cardiovascular diseases;
• restores the functions of the nervous system, supports its work without failures;
• removes excess fluid;
• improves intellectual activity, increases physical endurance;
• restores hormonal balance in the female body;
• prevents the early formation of wrinkles in women and men.

Also, this vitamin plays a key role in the production of antibodies, strengthening the immune system and reducing the risk of colds.

Daily dosage

Vitamin B6 is required by every person, but people with a weakened body need it especially urgently. They should pay more attention to their diet, undergo medical examinations in a timely manner, and carefully monitor their own health. Pregnant women, breastfeeding mothers, people who take antibacterial drugs for a long time, drinkers and smokers are at risk. As a rule, they have a lack of pyridoxine.

Daily dosages of vitamin B6 for different groups of people.

groups of people	Daily dosage of vitamin B6, mg
Children
Up to six months
From six months to 1 year
From 1 year to 3 years
4 to 6 years old
7 to 14 years old
Men
60 to 75 years old
Over 75 years
Women
From 18 to 60 years old
60 years and older
During pregnancy
During lactation

Increase the dosage of B6 should:

• when using drugs containing estrogen;
• during pregnancy, as estrogen levels rise;
• in the second half of the menstrual cycle;
• during weight loss (helps break down body fat);
• with stress and prolonged depression;
• while taking steroids;
• at the stage of puberty (in adolescence), if acne is concerned;
• with malnutrition, beriberi;
• if there is a high risk of developing a heart attack;
• in violation of immune functions;
• in case of high blood pressure;
• in the presence of psoriasis, diathesis, dermatitis.

Signs of a lack of vitamin B6

B6 deficiency is manifested by characteristic symptoms. However, they do not always indicate a vitamin deficiency, and sometimes indicate the development of another disease.

Vitamin B6 deficiency is characterized by:

• loss of appetite;
• nausea, vomiting;
• deterioration in mood, irritability;
• hair loss;
• sleep disturbance;
• inflammation occurring on the mucous membranes of the oral cavity;
• signs of anemia;
• conjunctivitis;
• the formation of blood clots, which often leads to blockage of blood vessels;
• deterioration of the skin, dermatitis;
• convulsions, muscle spasms.

In general, the natural protective functions of the body are reduced. If the lack of a valuable substance is not replenished in time, the water-salt balance is disturbed, edema appears, and malfunctions of the central nervous system and cardiovascular system occur.

Vitamin B6 in food: table

Natural sources of pyridoxine are food of both plant and animal origin. A list of products with a useful substance content is presented in the table.

Products plant origin
	Banana, avocado, citrus
	Corn, spinach, carrots, Brussels sprouts, corn, herbs
	Strawberry
cereals	Rice, buckwheat, flour, bran
Sunflower seeds
	Peanuts, hazelnuts, walnuts
Animal products
	chicken, beef
	Tuna, cod, salmon
by-products	Cod liver, cattle, heart, kidneys
Seafood
Dairy products

but the largest number B6, useful for maintaining health, is present in the liver and yeast.

On a note! When processing food, most of the B6 is lost. For example, when preserved, up to 50% is lost, when frozen - up to 40%, when exposed to high temperatures - up to 90% of the vitamin.

If possible, it is better to prefer products with a B6 content without pre-treatment. For example, fresh vegetables are more beneficial than stewed vegetables. And if you want to cook stew, it is advisable to choose steam processing.

Preparations containing vitamin B6

In addition to food, you can make up for the lack of B6 in the body with the help of vitamin complexes. Often they are presented in the form of tablets. The instructions usually recommend taking 1 tablet 1-2 times a day. Also, this water-soluble vitamin is presented in the form of injections, which are administered intramuscularly in 1 ml.

External use of B6 is also allowed. As a rule, the need for it arises with the appearance of wrinkles in women. It is included in age-related lotions and creams that provide proper care for aging skin. A concentrated pyridoxine 1% is used in adolescence to get rid of acne.

However, remember that an overdose of B6 can be harmful to health. Therefore, it is important to adhere to the prescribed dosages while taking this substance. Overdose leads to nausea, vomiting, allergic reactions.

Interaction with other vitamins

Only a doctor can determine the exact dose of vitamin B6. You should not engage in self-medication and taking a vitamin according to the instructions, so as not to harm your health. Improper use of B6 can adversely affect performance digestive system, neurological disorders, as well as failures in sensory-motor function, are not excluded.

It should be noted that pyridoxine interacts well with almost all vitamins. The exception is B12, which has a devastating effect on B6. Therefore, they are not recommended to be used together. In addition, pyridoxine itself interferes with the absorption of B1.

Vitamin B6 is extremely useful for all people, which is why it is so important to maintain its level, avoiding deficiency. In order not to resort to taking vitamin complexes, it is recommended to introduce food rich in B6 into your diet. Vegetarians can easily do without meat, as pyridoxine is found in vegetables, grains, soy, and nuts.

19 facts about vitamin B6 or pyridoxine - what products it contains, what are its functions in the body, indications for use and drug compatibility

Vitamin B6 - a substance "without special signs." Its name is not associated with anything significant among the majority of the population. Doctors know it under the name pyridoxine. However, the activity of this vitamin in the body can be compared with the work of a very good and very modest deputy: it participates in almost everything (and not in the last roles), and when it is absent, processes in different parts of the body can “collapse”. This “modest” vitamin is abused for a long time, but if overdose symptoms appear, then you will have to suffer for months.

The company Biolit is an enterprise with a modern research and production base that has been producing biologically active additives and cosmetic products based on extracts from plant and organo-mineral raw materials for more than 25 years.

dietary supplement. IS NOT A MEDICINE

• Vitamin B6 refers to three pyridine derivatives: pyridoxine, pyridoxal and pyridoxamine. In the body, their active forms in the form of phosphates can pass one into another, but pyridoxal phosphate remains the main one. Water-soluble vitamin B6 is easily absorbed in the small intestine by normal diffusion, the excess is excreted in the urine in half a day.
• B6 is unpretentious: it is stored for months in products, and an insignificant proportion of the substance is lost during cooking. At the same time, the sun's rays and various methods of sterilization and preservation are destructive for him.
• Pyridoxine phosphate and pyridoxal phosphate are part of many enzymes, more than 140 reactions in the body directly depend on them.
• B6 is the only vitamin involved in the metabolism of all three macronutrients (proteins, fats and carbohydrates). Especially important for amino acid metabolism. It is directly or indirectly necessary for the synthesis of adrenaline, dopamine, serotonin, GABA, histamine, methionine, arachidonic acid, heme, nicotinic acid and many other useful substances and compounds.
• The recommended daily intake of vitamin B6 for an adult is 1.3–2 mg. It's easy to get just by eating plenty of it: most non-canned foods contain some of this vitamin. Separately, the norm will be covered by about 200 g of beef liver, 300 g of walnuts, five bananas, 600 g of meat, 900 g of potatoes or 1.5-3 kg of white bread. On the other hand, an excess of fatty and fried food makes it difficult to absorb vitamin B6.
• Some lucky ones do not even need to overeat: up to 50–80% of the norm of vitamin B6 is capable of producing intestinal microflora. But for this, it must have the appropriate composition, which, in turn, is highly dependent on the same food. A lot of bread, for example, "own production" of pyridoxine will nullify.
• The main causes of vitamin B6 deficiency in the body are: insufficient or malnutrition, excessive alcohol consumption, pregnancy, inflammatory diseases of the small intestine, chronic renal failure, long-term hemodialysis, autoimmune diseases. Breastfed children have a vitamin deficiency in the mother for the reasons listed above. The absorption of pyridoxine is reduced in the elderly.
• These conditions have a bad effect on the metabolism of other vitamins, so isolated hypovitaminosis B6 is rare - as a rule, it is accompanied by a deficiency of folic acid and vitamin B12. In addition, hypovitaminosis B6 itself leads to nicotinic acid deficiency.
• Increases the risk of hypovitaminosis B6 taking the anti-tuberculosis drugs isoniazid, pyrazinamide and cycloserine, the antihypertensive drug hydralazine, the immunosuppressant penicillamine, oral contraceptives, theophylline, as well as antiepileptic drugs - valproic acid, carbamazepine and phenytoin.
• Since vitamin B6 is involved in the production of the main inhibitory neurotransmitter (GABA) from excitatory neurotransmitter (glutamate), antiepileptic drugs due to hypovitaminosis B6 can potentially increase the risk of seizure activity and reduce the effectiveness of anticonvulsant therapy.
• Taking the same preparations of vitamin B6 itself reduces the activity of levodopa and, according to some reports, phenobarbital.
• Symptoms of hypovitaminosis B6 are nonspecific, occur randomly and do not always suggest a lack of this vitamin: weakness, irritability, dizziness, loss of appetite, nausea, vomiting, liquid stool, various dermatitis and stomatitis, as well as glossitis, abdominal discomfort and venous thrombosis. In advanced cases, hypochromic microcytic anemia and generalized convulsions that do not differ from status epilepticus. Pregnant women have toxicosis. In infants - weight retention, hypochromic anemia, excitability, convulsions.
• To suspect vitamin B6 deficiency - with sufficient qualifications of the doctor - neurological symptoms can help. In the early stages, this is a bilateral numbness of the distal parts of the arms and legs, with a continuing deficiency of pyridoxine, progressing into "burning" paresthesia. Then weakness of the limbs develops, vibratory sensitivity and proprioception (sensation of body parts relative to each other - ed.) are disturbed, with intact pain and temperature sensitivity, gait and coordination suffer, convulsions occur. Hearing enhancement can be a small and not always pleasant compensation for the listed sufferings.
• Vitamin B6 is produced in the form of pyridoxine hydrochloride in tablets of 1, 2, 5 and 10 mg and in ampoules with a solution for injection of 10 and 50 mg. In addition, it is part of most vitamin complexes. Pyridoxine is also liked to enrich various breakfast cereals and other healthy meals.
• Vitamin B6 at a daily dose of 10–50 mg has been successfully used in the treatment of hypovitaminosis B6 and related clinical conditions, such as anemia (up to 600 mg/day), dermatitis, or seizures when taking isoniazid. With varying but proven success, vitamin B6 has been used to control nausea and vomiting in pregnancy (30–100 mg/day, divided into three to four doses), as well as PMS (80–500 mg/day).
• In addition, the drug can be prescribed for dozens of other diseases of the skin, mucous membranes and all internal organs. In reasonable doses, harm from it, most likely, will not be.
• Vitamin B6, together with vitamin B12 and folic acid, is involved in controlling the level of homocysteine, an amino acid that occurs during the metabolism of methionine. Homocysteine ​​damages the inner walls of the arteries, which contributes to the development of blood clots and atherosclerosis, as a result, the risk increases and worsens the course of cardiovascular diseases, Alzheimer's disease and senile dementia, placental insufficiency. In our country, some doctors like to pay increased attention to the control of homocysteine ​​levels when planning pregnancy, in some cases limiting themselves to prescribing folic acid, and forgetting about other participants in the reaction. The norm of vitamin B6 for pregnant and lactating women is 5 mg / day, the upper permissible limit of the norm is 80–100 mg / day. No teratogenic effect has been described.
• Vitamin B6 is generally tolerant of abuse. It is impossible to overeat it with food. But long-term use as a drug at a dose of 1-6 g / day for 1-3 years can cause severe progressive sensory neuropathy with ataxia (same as with hypovitaminosis B6), painful dermatitis, photosensitivity, nausea, pain in the heart . After discontinuation, the symptoms regress within a few months or even years. Isolated cases of the development of neurotoxic effects are described when taking 300-500 mg / day.
• Vitamin B6 is used in emergency medicine for mushroom poisoning with stitches and rocket fuel, more often when both are taken orally, but the miasma of the stitches can also be inhaled when cooking. The lines contain the toxin gyromitrin, which is converted in the body to monomethylhydrazine (found in rocket fuel). The latter, like isoniazid, inhibits the production of pyridoxal phosphate. The clinical picture of acute poisoning includes gastroenteritis, hemolysis, methemoglobinemia, acute liver and kidney damage, convulsions, and coma. In addition to resuscitation and detoxification measures, pyridoxine preparations are administered intravenously at a dose of 25 mg / kg of body weight.

• Neurotransmitters are actively synthesized - serotonin, gamma-aminobutyric acid, dopamine and norepinephrine.
• The supply of the nervous tissue with nutrient substrates improves.
• Prevents and eliminates spasms and muscle tremors.

The cardiovascular system:

• Ischemia, atherosclerosis and myocardial infarction are prevented, blood is thinned and blood pressure is reduced.
• The content of potassium and sodium in the blood and intercellular fluid is normalized.
• Reduces swelling of the face and limbs in chronic heart disease.
• Necessary for the synthesis of hemoglobin, reduces blood cholesterol, prevents thrombosis.
• Normalizes the work of the heart and increases its ability to relax during diastole.

Endocrine system:

• Maintains the balance of estrogen, preventing the appearance of tumors in women.
• Essential for the synthesis of most hormones.
• Contributes to the preservation of vision in diabetes mellitus.

Vitamins and the body

Vitamins - the most important elements for the body, are involved in the functioning of all organs. In the human body, vitamins are not formed (and if they are formed, then in scanty quantities), but come from outside, in the form of food. Vitamins help cells grow, strengthen the immune system, without them metabolic processes in the body are not carried out.

A person needs vitamins in very small doses, but the physiological need for them is daily and constant. A deficiency of at least one vitamin threatens with irreversible consequences for a person. The lack of useful elements negatively affects physical and mental abilities, tissues and internal organs, metabolism is disturbed, development and growth slows down.

With a complete and proper diet, the body receives all the required vitamins, which contributes to the production of hormones, regulation of the metabolic process, and synchronous functioning of organs. A person feels vigorous and healthy, tolerates cold, heat without problems, and is resistant to infections.

Stick to a proper, balanced diet and be healthy!

Pyridoxine for hair

With a lack of pyridoxine in the body, the hair dries out, breaks and splits. The scalp becomes oily, dandruff appears, hair grows poorly. Vitamin B6 has gained wide popularity among cosmetologists to eliminate such problems.

Hair Benefits

• Dry hair is hydrated due to the fact that vitamin B6 retains water.
• Increases hair growth.
• Due to the sedative effect, itching of the skin is eliminated.
• Hair stops falling out, thickens and strengthens.
• Eliminates dandruff.
• The blood supply to the roots improves, the hair becomes smooth, increases in volume and begins to shine.

The most popular masks with pyridoxine from ampoules. They must be applied to unwashed hair, covering the head with polyethylene and wrapping it in a thick towel. With significant hair loss, masks should be applied every other day, with a preventive purpose - 2 times a week.

Hair mask recipes

1. Heat 2 teaspoons of burdock oil in a water bath and mix with an ampoule of pyridoxine. Apply to damp hair and leave on for 2 hours.
2. Beat the chicken egg and mix with a tablespoon of almond oil. Add 1 ampoule of pyridoxine and vitamin B12, mix and apply overnight to dry hair. Leave for an hour, rinse with warm water and go to bed. Wash your hair with shampoo no earlier than after 8 hours.
3. Melt 2 tablespoons of honey, and add 1 ampoule of vitamins A, E, B6 and B12. Stir and pour into the mixture a teaspoon of sunflower oil and lemon juice. Apply for an hour, then wash your hair with shampoo.

Procedure

When conducting intramuscular injection, the following procedure must be followed:

• the patient is placed on the stomach, it is necessary that he completely relax the gluteal muscles;
• prepare a cotton swab moistened with alcohol;
• the tip of the ampoule is broken off, in connection with which it is better to wrap it with a napkin in order to avoid accidental injury to the finger;
• using a syringe, a solution is drawn from the ampoule;
• all the air is squeezed out of the syringe by turning it up with a needle (the piston must be pressed until a drop of solution comes out of the needle, which means that only liquid remains in the syringe; if there is air in the syringe, then when it is injected into the muscle a hematoma may form;
• the needle must be clamped between the middle and index fingers about one or two centimeters from the end;
• turn the palm so that the tip of the needle is under it, and the syringe is above the hand;
• make a slap in the place where the solution will be injected (most often this is the outer upper corner of a buttock); the needle must be inserted into the muscle two-thirds of its length;
• the drug is administered by gradually pressing the piston;
• the needle is removed and applied to the area where the solution moistened with alcohol swab was introduced. Here's how to inject vitamin B6 injections.

Vitamin B6 during pregnancy

During pregnancy, the body's need for pyridoxine increases by 1.5-2 times. It is prescribed in combination with magnesium, which increases the absorption of both elements (Magne B6). Pyridoxine eliminates morning sickness and leg cramps in the last trimester of pregnancy.

Indications for use::

• The threat of abortion.
• exfoliation of the placenta.
• Increased tone of the uterus.
• Spasms of skeletal muscles.
• Severe pregnancy and complicated childbirth in history.
• Frequent stress.
• Tachycardia.
• Arrhythmia.
• Hypertension.

Vitamin B6 in ampoules: price

The drug is inexpensive - 30-40 rubles.

The cost of drugs with additional vitamins is as follows:

- "Kombilipen", for five ampoules of which with a volume of two milliliters each you need to pay about two hundred rubles;

- "Vitagamma" - about a hundred rubles for the same amount;

- "Kompligam B" - about two hundred and fifty rubles, the volume is the same.

daily requirement

Increasing the dose by 25-30% is necessary:

• While taking birth control pills and medicines containing estrogen.
• In the last week of pregnancy.
• A week before the start of menstruation.
• While taking drugs based on steroids.
• With excess weight.
• With acne and inflammatory skin diseases.

If during the injection the patient felt unbearable acute pain, then the needle should be withdrawn immediately. Usually such feelings arise when the needle touches a nerve node.

It is impossible to crush and rub the place where the injection was made, because in this case the absorption of the drug will be disturbed, and injuries of the capillaries will form.

An injection is made into the thigh according to the same scheme, however, the patient must stand on one leg, and the second, where the solution will be injected, needs to be slightly bent. In this case, the body weight will be transferred to the supporting leg, and the muscle into which the injection is made will relax. Usually, vitamin B6 is not injected into the thigh.

When the injection is made, put a cap on the syringe needle, remove it and dispose of it. Reuse of the syringe is unacceptable because it is no longer sterile.

General information

The history of the discovery of the substance, which is now called pyridoxine, begins in 1934, and is associated with the name of the Hungarian doctor P. Giorgi. This doctor studied the manifestations of dermatitis in rats, and noticed that the disease disappeared under the influence of a certain substance, which he called vitamin B6. Four years later, S. Lepkowski was able to obtain the compound by processing yeast. In 1939, scientists in the field of biochemistry established the exact structure and chemical formula of the active compound.

By the name of vitamin B6 they mean a mixture of 3 chemical compounds with similar effects on the body - pyridoxal, pyridoxol and pyridoxamine. Later, the positive effects of the substance were established not only for dermatological problems, but also for diseases of the nervous system. Substance received good feedback doctors, and is now widely used in medicine.

assimilation

With intramuscular injection, the bioavailability of pyridoxine is 100%. In food, it is found in the form of compounds that break down in the small intestine. With the blood, vitamin B6 enters the liver, where it is dephosphorylated, and then phosphorylated. The maximum concentration is observed in the liver, kidneys and myocardium.

Lack of substance in the body

Acute deficiency of vitamin B6 develops mainly as a result of taking certain drugs or with concomitant diseases. For example, alcoholism develops beriberi B6: there is a change in mental abilities, a violation of motor functions, inhibition of reflexes and disturbances in blood counts. This is preceded by hypovitaminosis of vitamin B6. It develops with a non-critical, but persistent lack of a vitamin. In adults, the body can compensate for this condition, but not for long. For a child, especially at an early age, hypovitaminosis is dangerous.

Symptoms of hypovitaminosis:

• violation of the skin condition (redness, peeling, itching);
• the appearance of dry seborrhea;
• emotional instability;
• sleep disturbance;
• frequent colds;
• shift in circadian rhythms;
• depression;
• decrease in working capacity;
• disorders in the blood;
• astheno-neurotic syndrome;
• stomatitis;
• convulsions.

All these symptoms are non-specific and only a specialist after a thorough examination can make an accurate diagnosis.

What foods contain vitamin B6

Where is vitamin B6 found in animal products:

• Fillet of tuna, mackerel and sardine.
• Chicken and beef liver.
• Chicken fillet.
• Eggs.
• Shrimps and oysters.
• Beef and lamb.
• Dairy products.

herbal products:

• Hazelnuts, pine nuts and walnuts.
• Beans.
• Potato.
• Sea buckthorn and pomegranate.
• Horseradish and garlic.
• Bulgarian pepper.
• Green peas, soy and lentils.
• Bananas.
• Millet.
• Yeast.

How Vitamin B6 Works With Other Medications

The interaction of pyridoxine with other substances should be taken into account so that the drug is adequately absorbed and does not harm the effect of other medicines.

Friendly partners of vitamin B6 are magnesium, folic acid.

Antagonists slowing down mutual penetration are vitamins B1 and B12. Antibiotics inhibit the activity of pyridoxine. This also applies to anti-tuberculosis drugs, hormonal contraceptives.

Pyridoxine enhances the effect of diuretics, cardiac drugs (glycosides).

Vitamin B6 deficiency

Pyridoxine deficiency is characterized by:

• Excessive irritability, lethargy and mental dysfunctions.
• Insomnia and a feeling of unreasonable anxiety.
• Decreased appetite and developmental delays in children.
• Convulsive syndrome.
• flatulence.
• The formation of uroliths in the kidneys and bladder.
• Abnormal electroencephalogram readings.
• Peripheral neuritis, polyneuritis of the hands and feet.
• The development of anemia with a sufficient amount of iron in the body.
• Inflammation of the skin and mucous membranes.
• Stomatitis, rhinitis and conjunctivitis.
• Glossitis and ulceration of the oral cavity.
• Severe bleeding gums.
• Convulsive conditions in children under 7 years of age.
• Increased blood viscosity and its tendency to form clots that clog blood vessels and cause thrombosis.
• Nausea and vomiting.
• The inability of the immune system to synthesize antibodies.

Vitamin B6 deficiency symptoms

Vitamin B6 deficiency.
Primary symptoms can be:

• nervousness, increased irritability;
• weakness, high fatigue;
• depressive mood;
• anemia;
• tremor, muscle spasms, numbness of the extremities;
• cracking of the lips and corners of the mouth, stomatitis;
• dry or seborrheic dermatitis;
• hair loss;
• sleep disturbance.

In infants, vitamin deficiency manifests itself in the form of increased excitability, digestive disorders, convulsive syndrome, and growth retardation may be observed. During pregnancy, there is a loss of appetite, severe nausea, frequent vomiting, inflammation of the mucous membrane of the oral cavity and tongue, drying and peeling of the skin, and itching.

Determining a vitamin deficiency by external signs can be difficult. For example, night cramps can appear not only when pyridoxine is depleted, but also when there is a lack of tocopherol or magnesium, as well as due to diabetes, varicose veins, and some other diseases. Therefore, the doctor should deal with the identification of vitamin deficiency.

Overdose

Vitamin B6 is rapidly metabolized and excreted in the urine. Exceeding dosages by 50 times for several years does not lead to a deterioration in health. Increasing the dose hundreds of times can lead to:

• Peripheral blood flow disorders.
• Tachycardia and pain radiating to the left arm.
• Migraines, drowsiness and dizziness.
• Excitation and impaired coordination.
• Paresthesia of the arms and legs.
• The emergence of a feeling of pressure on the limbs (syndrome "stocking and gloves").
• Difficulty breathing.
• Anaphylaxis, urticaria, itchy rash, skin redness, dermatitis, Quincke's edema and photosensitivity.
• Nausea and vomiting.
• Deterioration of the immune system resistance against infections.
• Heartburn and increased production of gastric juice.
• Decreased folic acid content.
• Partial baldness.
• Disorders in the blood coagulation system.
• Fainting and convulsive syndrome with the introduction of large doses intravenously.
• Inhibition of milk production in nursing mothers.

Prolonged overdose causes a decrease in the amount of protein in skeletal muscle, liver, kidneys and heart.

Pyridoxine overdose and contraindications

The drug can not be prescribed for individual intolerance. Caution is required in coronary heart disease and severe liver dysfunction. With ulcerative-inflammatory lesions of the stomach or duodenum, an increase in the acidity of gastric juice is possible.

Vitamin B6 side effects.

Other side effects:

• migraine;
• asthenia, dizziness, fainting;
• numbness of the limbs;
• nausea, dyspepsia;
• angina pectoris, increased heart rate;
• fever;
• decrease in the secretion of breast milk;
• rash, itching, redness of the skin;
• photodermatitis, toxicoderma;
• anaphylaxis.

With prolonged use of large doses of the drug, hypervitaminosis develops. Its first signs are body rashes, dizziness, skeletal muscle weakness, tingling and numbness of the extremities.

In the future, other pathologies are possible:

• active hair loss;
• temporary loss of sensitivity of certain parts of the body, paresthesia;
• prolongation of bleeding time;
• weakening of the immune defense;
• metabolic failures;
• a decrease in muscle mass and dystrophy of internal organs due to excessive breakdown of proteins;
• peripheral neuropathy, tunnel syndrome;
• desynchronization of movements, progressive walking disorder.

Pathology with prolonged use.

In case of an overdose, it is necessary to stop taking pyridoxine and carry out symptomatic treatment.

The systematic use of this drug within the daily norm increases the likelihood of malignant tumors in the lungs in men by 1.4 times. This is not typical for women.

Preparations and forms of release

Vitamin B6 in ampoules – price 11 UAH / 35 rubles for 10 ampoules of 1 ml.

Composition: pyridoxine hydrochloride - 0.05 g, water for injection - up to 1 ml.

Need to use at home

However, situations often arise when vitamin preparations need to be injected at home. In addition, pyridoxine in ampoules is often used not for its intended purpose, but also for cosmetic purposes, for example, for scalp and hair care. If we also take into account such a factor as a low price, it becomes clear why they often experiment with it and add it to various home-made care products and masks.

Compatibility

The following drug interactions have been described:

• When taken simultaneously with diuretics, pyridoxine enhances their effect.
• Combined administration with hormonal contraceptives, cycloserine, penicylamine, isoniazid, hydralazine sulfate, ethionamide and immunosuppressants reduces the effectiveness of vitamin B6.
• Pyridoxine partially blocks the action of drugs for the treatment of Parkinson's disease and weakens the pharmacological effect of phenytoin.
• When combined with corticosteroid hormones, the content of pyridoxine in the body decreases.
• Simultaneous use with glutamic acid and asparkam increases the resistance of the brain to hypoxia.
• The parallel use of vitamin B6 and cardiac glycosides stimulates the production of contractile proteins in the heart muscle.
• Pyridoxine prevents complications from taking tricyclic antidepressants caused by their anticholinergic action (decreased salivation, anuria).
• Simultaneous administration with derivatives of chloramphenicol reduces the risk of ophthalmic pathologies.
• Vitamin B6 is compatible with vitamin B12, but mixing them in one container is not recommended.
• It is undesirable to mix pyridoxine with alkali solutions, iron derivatives and solutions of strong oxidizing agents.
• You can not mix vitamin B6 in the same container with solutions of adrenomimetics, ampicillin sodium salt, amphotericin B, ascorbic acid, phytomenaion, dipyridamole, sodium oxyferiscorbone, phenothiazine derivatives (chlorpromazine), furosemide, etamsylate and eufilin.

Combination with other substances

1. Incompatible with vitamins C, B1 - neutralize each other's action.
2. With B12 can only be taken at intervals of time.
3. Combines well with B2, K and B5.
4. It is prescribed together with cardiac glycosides in the treatment of vascular disorders, as well as with asparkam and glutamic acid to increase resistance to hypoxia. (More about vitamins for the heart and blood vessels)
5. It goes well with folic acid, as well as preparations of magnesium, calcium, zinc - it prevents the removal of these metals from the body.
6. Reduce the amount of B6 alcohol, oral contraceptives, anti-tuberculosis drugs, antibiotics.

Vitamin B3 (niacin, nicotinic acid, vitamin PP)

Vitamin B3 is a white powder, soluble in water. Chemically, it is the most stable of the other B vitamins when exposed to heat, ultraviolet light, alkalis, and air. Niacin comes from food, and can also be synthesized inside the body by converting the amino acid tryptophan.

The role of vitamin B3 in the body:

1. Metabolism: vitamin B3 is required for the synthesis of enzymes, for the absorption of fats, carbohydrates, proteins, promotes the release of energy, activates the metabolism of carbohydrates, and normalizes cholesterol metabolism. Takes part in over 50 enzymatic reactions.
2. Hormones: Niacin is required for the production of various hormones (sex, cortisone, insulin, thyroxine).
3. Cell Growth: Vitamin B3 is involved at the DNA and RNA level in the repair of genetic damage inflicted on the cells of the body by drugs and viruses.
4. Nervous System: Niacin supports the normal functioning of the brain and central nervous system.
5. Cardiovascular system: vitamin B3 helps to increase venous pressure and lower arterial pressure.
6. Blood System: Niacin stimulates the synthesis of red blood cells.

Vitamin B3 in food

The predominant content of vitamin B3 in animal products: liver, eggs, kidneys, fish, lean meat. To a lesser extent, it can be found in the composition of foods of plant origin: asparagus, parsley, carrots, garlic, green peas, peppers, cabbage. Also, vitamin B3 is found in legumes, mushrooms, and cereals (especially buckwheat).

Lack of nicotinic acid

Lack of nicotinic acid causes the following symptoms:

• fatigue, weakness;
• insomnia;
• perversion of taste, soreness of the tongue;
• dry skin;
• pallor of cheeks, lips, hands;
• weakening of memory.

A prolonged lack of nicotinic acid due to chronic malnutrition or the same type of nutrition can cause pellagra - a pathology in which there is a severe lesion of the gastrointestinal tract, skin, central nervous system up to mental disorders. As a rule, this disease is accompanied by a deficiency of other B vitamins.

Lack of vitamin B3 is observed in atherosclerosis, hypertension, diseases of the liver, thyroid gland, ulcers, cholecystitis, gastritis, rheumatism.

Average daily norm of nicotinic acid- 20 mg, the maximum allowable amount is 60 mg, for children the norm is 5-20 mg.

An excess of vitamin B3 can cause a rush of blood to the face, vasodilation. Excess is dangerous for the liver.

Brief information

Pyridoxine is what vitamin? AT 6. It is important to distinguish it from the "brother" of pyridoxine - vitamin B12.
Pyridoxine itself is a biosubstance with universal properties. Its main role is participation in protein metabolism. In addition, it also helps fat and carbohydrate metabolism in the body. Provides a balance of sodium and potassium in various biological fluids. And this is very important for the nervous system.

In addition, pyridoxine is involved in the synthesis of red blood cells, as well as their most important component, hemoglobin. It is of great importance in the release of carbohydrates accumulated in the muscles and liver in the blood. This process is important primarily because the nerve cells are evenly supplied with glucose. Approximately half of all B6 available in the body is involved in this process.

It is important to note that for this vitamin, exposure to direct sunlight, heat and the aquatic environment is detrimental. Therefore, when preparing products with its content, it is necessary to abandon heat treatment, cooking in water, broths, brines. This product must be stored in a dark place.

Biological effects

During treatment, it is possible to develop allergic reactions, hypersecretion of hydrochloric acid.

Pyridoxine (mainly in the form of its coenzymes) contributes to:

• Active breakdown of fats, which helps to lose weight.
• Stimulate the metabolic process and increase the production of cellular energy.
• Increasing performance and endurance.
• Normalization of the hematopoietic system, stabilization of the production of hemoglobin and red blood cells.
• Improving the process of transmission of impulses of inhibition and excitation in the central nervous system and increasing resistance to stress loads.
• Maintaining an optimal level of homocysteine ​​in the blood, which prevents the destruction of cells in the walls of blood vessels and the occurrence of cardiovascular diseases.
• The normal course of metabolic reactions and the transformation of amino acids.
• Stabilization of cholesterol and blood sugar levels.
• Activation of gluconeogenesis in the liver (synthesis of glucose from non-carbohydrate components), which increases the tolerance of heavy physical exertion.
• Improvement of the skin.
• Release of the liver from fatty deposits.

Vitamin B6 (pyridoxine hydrochloride) - an important element in a healthy diet, was discovered quite by accident in the 20s of the last century. It is a transparent, highly soluble substance that is unable to accumulate in the body, so it is completely eliminated within 5-8 hours.

Pyridoxine and pyridoxine hydrochloride belong to the group of biologically active coenzymes. The properties of these compounds are identical.

To many, this name (pyridoxine hydrochloride) will seem strange and even frightening. However, this is an absolutely safe substance with a lot of useful properties. Externally, the composition of vitamin B6 is transparent crystals, highly soluble in water and ethanol, the resulting aqueous solution does not mix with fats and essential oils.

Easily decomposed by light, does not oxidize in air, melts when heated without chemical degradation. The term "hydrochloride" means that the compound belongs to the class of salts of the acid HCl.

What are the indications for the use of B6? What are the symptoms of its excess and deficiency in the body, and what is the daily rate of its consumption by an adult? We will consider all these questions below.

Valuable properties

Pyridoxine is extremely important for women's health: it is involved in nerve transmission and regulates hormonal metabolism; during pregnancy, this substance reduces the effect of contraceptives.

Timely intake of this vitamin reduces the risk of malignant neoplasms, vitamin B6 (pyridoxine hydrochloride) binds free radicals and prevents premature aging, favorably affects the condition of the skin of the face, hair and the whole organism as a whole.

It can be used both inside and as part of anti-aging masks and creams. Scientists have found that pyridoxal has unique properties to reduce destructive processes leading to the destruction and decrease in elasticity of collagen fibers.

Almost all biochemical processes in the body proceed with the participation of pyridoxine (vitamin B 6), it creates conditions for the synthesis of proteins, promotes the breakdown of fats, speeds up metabolic processes and helps to eliminate toxins. In the absence of pyridoxine, exchangeable oxalic acid forms complexes with calcium oxalates and promotes stone formation in the kidneys.

B6 also helps to reduce the amount of cholesterol plaques on the walls of blood vessels (together with thiamine), reducing the risk of stroke and heart attack. Pyridoxine hydrochloride is quite widely represented in a wide variety of products, however, due to incomplete digestibility, the lack of this substance is still observed quite often. According to scientific research Approximately 20 out of every 100 people are deficient in vitamin B6.

Researchers in the field of obesity and excess weight are busy looking for substances that effectively break down fats. Among these agents, vitamin B6 (pyridoxine hydrochloride) occupies a central place.

A unique weight loss product - a dietary product, where pyridoxine hydrochloride is contained in large quantities, it copes well with the task of weight correction.

However, miracles should not be expected: the effect is noticeable after months of following a strict diet, in which, in addition to this substance, vitamin B1 is necessarily present.

During pregnancy

Pyridoxal is involved in the formation of red blood cells, nerve cells and synapses, which ensure the transmission of nerve impulses.

These and many other processes are necessary during the formation of the fetal brain in the womb.

This representative of group B substances is an intermediate link in the synthesis of amino acids for the skin and its derivatives, therefore vitamin B6 for hair is an indispensable and important element.

In addition to vital functions, pyridoxine hydrochloride has many other beneficial properties. First of all, it facilitates the postoperative period, weakens the action of toxins.

It is able to effectively remove toxins and cleanse the body during the period of poisoning.

Vitamin B6 (pyridoxine hydrochloride) weakens the strength of muscle contractions of the uterus, which is greatly facilitated in combination with magnesium and B1.

The daily rate of pyridoxine hydrochloride directly depends on lifestyle, gender, age, bad habits and increases with the amount of meat products consumed.

daily rate for different categories:

• Adults: 2.5 mg
• Children under 14: 0.3–1.0 mg
• Children 14 to 18 years: 1.0–1.6 mg
• Pregnant women: 4–6 mg.

Vitamin B6 pyridoxine hydrochloride is able to be synthesized by ordinary E. coli, but you should not rely on this source: in our time, there is hardly a person with a completely healthy microflora in today's difficult environmental situation.

It is known that the properties of vitamin B6 are enhanced by the use of mineral supplements. Such synergy is provided, in particular, by magnesium and potassium salts, as well as another representative of group B - B1 (thiamine). Together they increase the absorption of vitamin B6. One of the possible mechanisms is the additional production of gastric juice.

Alcohol abuse, smoking, simultaneous intake of relaxing and sedative drugs slow down the absorption of vitamin B6. Also, during anti-tuberculosis treatment or taking antibiotics, vitamin B6 is partially destroyed.

Vitamin B6 (pyridoxine hydrochloride) for hair serves as an active coenzyme, gives them shine and beauty, prevents split ends and eliminates brittleness. Mutual antagonism is possessed by vitamins B1 and B12. It is not recommended to take them simultaneously with drugs for Parkinson's disease, but in order to obtain a good cosmetic result, joint use with B1 is possible.

Biological role

The main pharmacological effects of vitamin B6 (pyridoxine) are:

1. Participation as a coenzyme in all reactions of protein metabolism, transformation and breakdown of amino acids.
2. Acceleration of fat metabolism, increased mobilization of lipids from reserves in the body, influence on the processes of weight loss.
3. Stimulation of hematopoietic reactions in the bone marrow: the substance is responsible for the synthesis of the protein part of hemoglobin and the maturation of red blood cells.
4. The production of a sufficient number of neurotransmitters necessary for the transmission of nerve impulses.
5. Strengthening immunity, increasing the chemotactic function of neutrophils and accelerating the synthesis of antibodies.
6. Regulation of the level of mediators in the brain, participation in the processes of excitation and inhibition of the central nervous system.
7. Decreased indicators of "bad" cholesterol in the blood, normalization of the lipid profile.
8. Increasing the sensitivity of cells to insulin, reducing blood glucose levels, preventing metabolic syndrome.

Vitamins B6 are useful for female body during pregnancy, since they reduce the affinity of uterine receptors for tonic substances, they are responsible for the prevention of miscarriages and premature births. In young children, sufficient pyridoxine intake is necessary to prevent seizures. Also, the connection is necessary for the beauty and youthfulness of the skin.

metabolic pathways

Vitamin B6 is highly bioavailable, most of the substance is absorbed in the small intestine when taken orally. When it enters the bloodstream, the structural formula undergoes biochemical phosphorylation reactions, as a result of which it turns into pyridoxal phosphate. When passing through the liver, the compound passes into an inactive form (pyridoxylic acid), which is excreted through the kidneys. More than 70% of the vitamin accumulates in the muscles in a bound state, about 10-12% is deposited in the liver parenchyma, a small amount of the substance circulates in the bloodstream.

Where is contained

Sources of Vitamin B6

Vitamin B1 (thiamine)

Vitamin B1 from the B vitamins was the first to be discovered. It dissolves in water and requires daily replenishment. It can be supplied with food and synthesized by the intestinal microflora.

During cooking, about 25% of the vitamin is lost. Easily destroyed during heat treatment, prolonged boiling, in contact with metals.

Thiamine is lost during the refining of cereal products (examples, cereals fast food, muesli, etc.) Alcohol, tobacco, coffee and food products, which contain citric acid salts and carbonic salts, reduce the absorption of vitamin B1.

The role of vitamin B1 in the body:

1. Metabolism: thiamine is involved in virtually every process at the cellular level, since it is involved in energy production (ATP), in the metabolism, primarily carbohydrates, amino acids, and protein digestion.
2. Nervous system, brain: vitamin B1 ensures the normal functioning of the central nervous system. It is also called the “vitamin of good spirits” due to its positive effect on nervous system and intellectual ability. It is involved in the production of acetylcholine, a neurotransmitter that affects several brain functions, including memory, maintains the tone of the muscles of the heart, stomach, and intestines.
3. Genetic Information: Vitamin B1 is essential for copying the genetic material passed from one cell to another during cell division.

Vitamin B1 in food

Vitamin B1 can be found in following products: cereals, cereals (millet, buckwheat, oats), wholemeal flour, apricots, hazelnuts, walnuts, almonds, green peas, rose hips, carrots, radishes, red beets, beans, onions, cabbage, spinach, potatoes.

The increased content of thiamine is found in bran, grain sprouts, yeast, and legumes. A small amount is noted in milk, eggs, lean pork.

The norm of vitamin B1

The norm of vitamin B1 in adults is due to age and stress - from 1 to 2.5 mg. In children, the need for the vitamin ranges from 0.5 to 2 mg.

In case of poisoning with heavy metals, nicotine, in stressful situations, increased amounts of thiamine are required at the upper permissible level - 5 mg.

A diet high in carbohydrates and alcohol increases the need for vitamin B1. If the intake of food rich in proteins and fats increases, the need decreases.

Vitamin B1 deficiency

One of the main reasons for the lack of vitamin B1 in the body is the monotonous diet of products that are made from finely ground grains, as well as the excessive consumption of refined carbohydrate foods and sweets. In addition, the cause of deficiency may be the consumption of foods rich in thiaminase, an enzyme that destroys thiamine. Every fourth alcoholic suffers from thiamine deficiency.

Vitamin B1 deficiency provokes the development of beriberi disease in advanced cases. The following symptoms are typical for her:

• from the side of the central nervous system: irritability, headache, memory loss, peripheral polyneuritis (inflammation of the peripheral nerves), paralysis in severe cases;
• from the side of the cardiovascular system: pain in the heart, tachycardia, edema, shortness of breath;
• from the gastrointestinal tract: constipation, loss of appetite, nausea, abdominal pain.

Vitamin B1 deficiency causes the following negative effects:

1. Violations of amino acid transamination processes.

2. Decreased protein biosynthesis.

3. Disorders of the functions of the cardiovascular, nervous systems, digestive tract. The reason is a violation of the oxidation of carbohydrates and the accumulation of under-oxidized products in the urine and blood, inhibition of the production of acetylcholine, the most important neurotransmitter. More about signs:

1. From the side of the central nervous system: coordination worsens, brain functions are disturbed, emotional and mental depression, irritability, lethargy are observed, memory decreases, exhaustion and muscle weakness, nervousness, lack of sensitivity or burning in the legs and arms, pain threshold decreases.
2. From the gastrointestinal tract: diarrhea, constipation, weight loss, liver enlargement.
3. From the side of the cardiovascular system: there is shortness of breath even with slight physical exertion, swelling of the legs and arms, low blood pressure, tachycardia, acute cardiovascular failure.

Hypervitaminosis

An excess of vitamin B6 is rare, since pyridoxine is excreted by the kidneys within 8-10 hours. Hypervitaminosis develops with a single use of large doses of the substance (more than 2 g). Harm B6 is manifested by peripheral neuropathies, paresthesias in lower limbs, partial baldness. With prolonged overdose, the activity of immunity decreases, the risk of spontaneous bleeding increases, and progressive muscle weakness develops. This condition requires immediate discontinuation of the drug and the appointment of symptomatic agents.

Vitamin B12 (cyanocobalamin)

Vitamin B12 is a bright red water-soluble substance with a cobalt molecule in the middle. The average adult human body contains 2 to 5 mg of vitamin B12, 80% of which is located in the liver.

Vitamin B12 enters the body with food, and is also partly produced in the intestines.

It is stable at elevated temperatures, however, is destroyed during cooking with water and meat juices. The activity of vitamin B12 decreases under the influence of oxygen, ultraviolet rays, as well as in alkaline and acidic environments.

The role of vitamin B12 in the body:

1. Metabolism: Vitamin B12 is required for the release of energy from food, the absorption of a number of fats and amino acids, and the conversion of folate from a passive form to an active form. Vitamin B12 is most needed for rapidly dividing cells, such as bone marrow and epithelial cells.
2. Nervous system, brain: cyanocobalamin is necessary for the formation of myelin, the protective sheath of nerve fibers, neurotransmitters, prevents the development of various kinds of emotional disorders.
3. Blood system: vitamin B12 stimulates the blood coagulation system, promotes the maturation of red blood cells, strengthens the immune system.
4. Cell division: cyanocobalamin is involved in the synthesis of nucleic acid that forms DNA.
5. Liver: vitamin B12 reduces blood cholesterol levels, has a beneficial effect on the functioning of the body.

Average daily vitamin b12 norm- 3 mcg, the maximum allowable amount is 9 mcg.

Vitamin B12 in food

Vitamin B12 in animal products: fish, liver, kidneys, soy, heart, sea kale. Milk and lactic acid products contain small amounts of B12.

Vitamin B12 deficiency symptoms:

• loss of appetite;
• weakness;
• pain and spasms in the stomach;
• constipation;
• gastroduodenitis;
• peptic ulcer of the duodenum and stomach.

Spicy vitamin B12 deficiency accompanied by a severe form of pernicious anemia, mental and neurological disorders.

An excess of vitamin B12 does not provoke toxic effects.

Pyridoxine hydrochloride - release form, mechanism of action, dosage of the drug, analogues and reviews

Medical sites and forums in most cases contain positive reviews about Pyridoxine. This drug is prescribed to many patients in the complex therapy of a variety of disorders, for example: hypovitaminosis B6, leukopenia, atherosclerosis, diabetes mellitus, herpes zoster, psoriasis, neurodermatitis, and so on. Almost always, this vitamin significantly accelerates the healing effect.

However, some users ask: Pyridoxine - what is it? And when they find out that this is the name of vitamin B6, they are very surprised. As you know, Pyridoxine helps well with toxicosis of pregnant women, eliminates the symptoms of air and seasickness. But the fact that this substance is used in the combined therapy of diseases of the central nervous system is not known to many.

It should be noted that often patients do not use the drug in ampoules, but its tablet form.

Among the many positive reviews there are reports of the development of negative effects. In some patients, while taking this medicine, the acidity of the gastric contents increased, which caused severe pain in patients with gastritis. However, experts say that compliance with dosing and taking into account contraindications - ulcers and stomach diseases, will not lead to the development of side effects, since the drug is well tolerated. In rare cases, allergic reactions develop, but, as a rule, all symptoms are eliminated after discontinuation of the drug.

Dosage

Permissible medicinal doses

• For an adult, about 2.2-2.4 mg of vitamin B6 per day
• Pregnant and lactating women - it is necessary to increase the intake by 0.5 mg.
• Children up to six months need about 0.3 mg of pyridoxine per day, subsequently, this need increases, reaching 0.5 mg by the age of 1 year, and 1.5 mg per day by 10 years.

At some points, daily doses of pyridoxine should be increased. For example, with the systematic use of contraceptives, the absorption of this vitamin is disrupted.

But often, additional doses of pyridoxine are prescribed for the treatment of specific diseases.

A complex of effective and useful properties of the substance

Understanding why the body needs vitamin B6, it is important to maintain its reserves by ensuring daily intake of vitamin-containing preparations.

Due to which there is a general recovery and preservation of youth, the beneficial properties of the element are in the following effects:

• a normal level of digestion of protein foods and useful fatty compounds;
• active production from tryptophan of the amino acid niacin, indispensable for the body;
• inhibition of irritation of the nervous system and skin manifestations of various diseases;
• removal of symptoms associated with indigestion and vomiting;
• normalization of the synthesis of nucleic acids that slow down the aging process of tissues;
• reduction of muscle spasms, convulsive manifestations, numbness of the extremities;
• normalization of the process of urination and acceleration of general metabolic processes.

It is prescribed by specialized specialists for various diagnosed diseases, such as leukopenia and air or sea sickness.

The use of vitamin-containing preparations is useful for those who suffer from anemia and hepatitis, toxicosis during pregnancy and nervous disorders of varying complexity.

Power adjustment

The appointment of synthetic or natural vitamin supplements does not eliminate the need to monitor the child's diet. The daily children's table should be complete and balanced.

The active period of growth falls on the age of 5-6 years. Children at this age should receive more energy.

Healthy foods

1. Especially important is the presence in the diet of meat and fish rich in proteins and fatty acids.
2. As additional sources of omega-3, it is recommended to give walnuts and hazelnuts.
3. Daily consumption of fermented milk products contributes to the proper functioning of the intestines and, as a result, good absorption of useful elements from food.
4. Be sure the menu should include fresh vegetables and fruits in quantities appropriate to age.

Mandatory products on the menu of a 6-year-old child: meat, fish, kefir, eggs, apples.

Application features

As we wrote above, it is better to take B vitamins all together. The only exception is thiamine (B1), which does not combine well with riboflavin and cobalamin (B12). The dosage of all micronutrients must be carefully calculated.

READ ALSO: which vitamins are better to choose for children 7 years old?

All vitamin elements work well with zinc, iron, and calcium, helping to make these minerals easier to absorb. Scientific evidence is available regarding a positive response to these drugs in an organism weakened by stress of an emotional nature, as well as in people with distracted attention and difficulties in cognitive processes.

Sources B6

Pyridoxine (vitamin B 6) is found in many food products both plant and animal origin. The substance can be destroyed under the influence of environmental factors: when freezing products, up to 90% of the nutrient is lost, during heat treatment - from 20% to 60%.

Table 2. Content of B6 per 100 g of food

Details on the benefits of vitamin B6 obtained from natural sources (video):

Sources of Pyridoxine

Vitamin B6 must be present in the body constantly - it is synthesized by the intestinal microflora. But for this process, material is needed - food that a person consumes.

Therefore, you should know which products are the source of B6 in order to introduce them into the daily menu.

Among the products of animal origin, first of all, beef and cod liver should be distinguished. Pyridoxine is also present in other meat and fish products, as well as in dairy and eggs.

Vegetable sources include vegetables: spinach, cabbage of all varieties, legumes, potatoes, tomatoes, carrots. Also, you need to eat strawberries, bananas, avocados. There is Pyridoxine in nuts and yeast.

Vitamin supplement foods

Knowing which foods contain vitamin B6, you can independently replenish the body's reserves of useful substances without resorting to the use of dosage forms.

The consumption of elements with food is necessarily associated with the minimum temperature processing of food, to increase efficiency:

• vegetable products. This group includes brewer's yeast, ovaries and wheat bran, melon and broccoli, carrots and cabbage (cauliflower, Brussels sprouts and white cabbage), garlic and asparagus are considered useful vegetables;
• meat products and offal. To saturate the body with vitamin components with a high content of B6, it is necessary to replenish the diet of pork or beef liver and kidneys, heart and beef, lean pork.

A sufficiently high content, capable of replenishing the reserves of pyridoxine, is observed in fresh eggs and milk, molasses.

Cod and tuna remain invaluable storehouses of vitamin B6, which are important to eat regularly, which contributes to the restoration and normalization of protein and energy metabolism.

Reasons for an overdose

As already mentioned, vitamin B6 is very well excreted from the body with urine, so hypervitaminosis is possible only in rare cases. It occurs:

• in people suffering from hypersensitivity to this substance;
• if you take it for too long in large doses that the body does not have time to remove (this is typical for athletes and people who are actively involved in gyms - as a rule, men who are fond of bodybuilding);
• in case of rapid intravenous injections.

IMPORTANT! Sometimes an overdose occurs in children who have reached the vial of vitamins. Parents should remember that vitamins are useful only in strictly defined quantities. The daily intake of vitamin B6 for children should not exceed 1-1.7 mg (details above).

In addition, you need to know that any synthetic vitamins - in pure form or as part of vitamin complexes - should be taken after consulting a doctor. Only a knowledgeable specialist after appropriate research can assess the body's need for a particular substance.

To rule out possible hypervitaminosis, vitamin B6 is best taken in its natural form by eating foods rich in it.

Side effects of drugs with vitamin B6

Some commercially available multivitamins contain very high dosages of vitamin B6. This is especially true of dietary supplements used by athletes and people actively involved in gyms to increase muscle mass.

In the early stages, side effects are manifested in the form of allergic reactions. Such drugs should be taken with caution, do not exceed the recommended doses and take breaks.

Vitamin B6 and magnesium

Vitamin B6 works very well when paired with magnesium. They improve absorption and enhance each other's action. In the case of taking such drugs, an overdose of B6 does not occur.

Products

Most of the compounds in this group are found in:

• yeast;
• dairy products - cheese, milk, cottage cheese;
• germinated grains;
• liver;
• legumes;
• green vegetables;
• fish;
• eggs;
• nuts.

As you can see, the most ordinary products can boast and please the content of useful trace elements. Their beauty also lies in the fact that even heat treatment is not able to destroy them. A nursing woman should carefully ensure that her diet is varied and balanced. As for a grown up child who has already begun to try complementary foods and is approaching a complete transition to adult food, he will need to replenish his daily diet with some of the foods listed above.

Good nutrition is not always possible or not always possible, so it is possible to make up for the deficiencies of some vitamins using vitamin complexes. When a child has some of the above symptoms, reflecting a lack of useful micronutrients, then you should definitely start to make up for their deficiency, but before that, be sure to consult a doctor.

Vitamin B 6 forms for medical use

Due to the variety of forms of release, it turns out to have a stronger effect on the source of the problem or to simplify the reception. For example, for prevention purposes, children are given vitamin B6, which is available in tablets, which allows you to carefully control the concentration in the body, because the injection is not always suitable for babies.

Each preparation, which includes vitamin B6, has a different instruction for use. Despite the identical names of medicines, each of them must be read separately.

In ampoules: characteristics and names of drugs

Vitamin B6, which is available in ampoules, contains 10 or 50 mg of active ingredient per 1 ml of solution. The liquid can be taken intramuscularly or intravenously, depending on the drug. When injecting with drugs based on vitamin B6, it is necessary to monitor the sterility of the devices. Before injecting vitamin B6, it is worth learning the execution techniques, it is recommended to ask a medical professional for advice or perform the procedure.

Among the popular drugs in ampoules are:

Vitamin B6, or pyridoxine, is one of the vitamins that dissolves easily in water and is quickly excreted from the body. It is unable to accumulate human body, therefore it is necessary to ensure its constant replenishment.

Unlike many other vitamins, pyridoxine is not destroyed by heat treatment, but is not stable to light exposure.

The role of vitamin B6 in the body: what is it for

Pyridoxine performs a number of important functions in the human body:

• regulates the level of lipids and cholesterol in the blood;
• ensures the normal functioning of the nervous system - peripheral and central, contributing to the production of biologically active substances that transmit nerve impulses along the fibers;
• takes part in the synthesis of red blood cells;
• promotes the production of enzymes that are involved in all vital processes of the body;
• has a diuretic effect in violation of the water balance;
• helps in the production of hormones, in the conversion of important trace elements;
• regulates the balance of sodium, magnesium, potassium and glucose in the blood;
• contributes to the normal functioning of the glands of the body - the thyroid gland, adrenal glands;
• accelerates metabolic processes in brain cells, which ensures physical and mental performance;
• regulates the level of acidity of gastric juice;
• promotes the removal of toxic substances from the body in case of various poisonings;
• increases energy production;
• participates in the synthesis of nucleic acids that prevent cell aging;
• stabilizes the level of sex hormones - estrogen, progesterone, testosterone; as well as a hormone that is produced by the adrenal glands during stress.

In combination with other B vitamins, pyridoxine helps to fight many diseases of the heart and blood vessels, among which: atherosclerosis, ischemia, myocardial infarction.
