BIOTIN (VITAMIN B7, H)

BIOTIN - GENERAL

Vitamin B7, H (other names are biotin or coenzyme R) - a water-soluble compound of B vitamins, necessary for maintaining normal blood glucose levels, gluconeogenesis, metabolism of carbohydrates, fatty acids, proteins. The substance got its name from the word "Bios", which translated from Greek means "Life".

Today there are 8 forms of vitamin B7, but only one of them is biologically active - D-biotin, found in natural compounds.

The molecule of coenzyme R is made up of tetrahydrothiophene, tetrahydroimidazole rings, while in the first of them one hydrogen atom is replaced by valeric acid.

The value of biotin for the human body can hardly be overestimated. The compound ensures the course of many biochemical reactions, regulates carbohydrate and fat metabolism, and maintains the normal state of the skin, hair, and nails. In addition, vitamin H improves the functioning of the digestive tract, nervous system, prevents the development of dermatitis, eczema, psoriasis.

Biotin is resistant to the influence of X-rays and UV rays, it dissolves well in water, alcohol, and is destroyed under the influence of high temperatures (the melting process starts from 232 degrees).

The chemical formula of vitamin B7 is C 10 H 16 N 2 O 3 S

THE VALUE OF BIOTIN IN THE BODY

Vitamin B7 takes part in the course of many metabolic processes, for this reason, chemical scientists included the compound in group B.

Despite the fact that biotin in the human body does not act independently, but only in the presence of digestive enzymes, the substance is necessary for the implementation of energy reactions, growth, the formation of muscle, epithelial, connective, and nervous tissues.

BIOLOGICAL ROLE OF VITAMIN H


Biotin is involved in carbohydrate metabolism.

The main function that vitamin H performs in the human body is to regulate carbohydrate metabolism. It promotes the breakdown of glucose, which is necessary to provide energy storage and maintain brain activity. Vitamin H (biotin) takes part in the carbohydrate metabolism of the body, that is, it promotes the absorption of carbohydrates, without which our body would not receive the necessary vital energy. It works well with insulin (a hormone produced by the pancreas) to regulate blood sugar levels and thus reduce the risk of diabetes. In addition, vitamin H takes part in the production of glucokinase, a substance that stimulates glucose metabolism. Thus, we can say that vitamin H is a vitamin of energy and vitality.

Biotin controls the processes of gluconeogenesis.

Biotin (vitamin H) plays an important role in the synthesis of glycogen, a carbohydrate stored in the liver and muscles. And through participation in gluconeogenesis- the conversion of amino acids into glucose, it helps to maintain normal blood sugar levels. In addition to glucose, vitamin H helps to better assimilate protein, and during metabolism it “cooperates” with B vitamins: folic and pantothenic acids and vitamin B12. Also, biotin is involved in the breakdown of fatty acids and fat burning reactions.

Biotin is a "beauty vitamin".

Biotin (vitamin H) is an excellent and reliable supplier of sulfur to the cells of the body. Sulfur compounds play an irreplaceable role in the formation of collagen - a substance that forms the basis for bones, skin, nails and hair. That is why it is impossible to maintain a blooming appearance without biotin: healthy hair, smooth and strong nails, radiant skin. Not to mention strong bones. Due to the fact that biotin (vitamin H) is involved in the control of fat metabolism and is found mainly in the cells of the skin and hair, it naturally regulates the fat content of the skin tissues. Therefore, with a sufficient content of vitamin H in the body, the general structure and appearance of the hair improves. In addition, additional intake of biotin stops hair loss and stops the separation of the nail plates.

Biotin supports the nervous system.

Biotin acts as a catalyst for glucose in the metabolism, which is necessary for the nutrition of our brain cells. To create normal conditions for the nervous system to work, you need to maintain sugar levels in the range of 80 to 100 milligrams in 100 milliliters of blood. If this indicator drops by at least 20 milligrams, the person begins to get tired quickly, gets irritated over trifles, becomes nervous and unbalanced. When glucose drops to 40 milligrams per 100 milliliters in the blood, the body needs rest in the morning, the desire to go to work disappears, and there is a feeling of lack of strength. With a further decrease in sugar, a person cannot get up from the pastel, realizes that he is sick. The female body, unlike the male, accumulates much less glucose, as a result, for the synthesis of monosaccharide, the beautiful half of humanity needs more vitamin B7.

Biotin is involved in the production of purine nucleotides, which are responsible for the transmission of hereditary information, the formation of DNA molecules. In addition, coenzyme R regulates the work of genes that provide intermediate metabolism.

AND:

  • Activates the function of vitamin C.
  • Participates in the synthesis of hemoglobin, beneficial intestinal microflora, proliferation of immune system lymphocytes.
  • Burns fat, improves the absorption of proteins, the condition of the gastrointestinal tract.
  • Participates in the transfer of carbon dioxide.
  • Needed for the normal functioning of the thyroid gland.

SUCTION AND EXCHANGE

After the compound enters the digestive tract, a large amount of vitamin H is concentrated in the human liver and kidneys, then it is supplied to all organs.

Vitamin B7, supplied with food, bound to protein, is initially released under the influence of proteolytic enzymes, then absorbed by the intestines, being deposited in the adrenal glands, kidneys, and liver. In this case, biotin is partially bound by serum albumin.The level of vitamin in the blood practically does not change.

In healthy people, urinary excretion of biotin is 11-183 micrograms per day (Oppel). In the event of the onset of B7-avitaminosis, the excretion of the compound in the urine decreases to 3.6 - 7.3 micrograms. With the introduction of more than 300 micrograms of a substance into the body, its significant increase in the concentration of the nutrient in urine is noted, while after 6 hours 30-50% of biotin is excreted naturally. Under these conditions, the content of coenzyme R in feces remains practically unchanged. Normally, the level of the substance is in the range of 322 - 393 micrograms per day.

In patients with poliomyelitis, the excretion of vitamin H increases by 3 times.

In women, the content of the vitamin compound in milk in the first days after childbirth is insignificant, while on day 10 its level increases to 0.38 micrograms per 100 milliliters. Subsequently, it reaches 0.9 - 11.2 micrograms. Thus, in human milk, the average content of a useful nutrient is twice as high as immediately after childbirth.

DAILY NEED

Physiological requirements for biotin according to Methodical recommendations МР 2.3.1.2432-08 on the norms of physiological needs for energy and nutrients for various groups of the population of the Russian Federation:

  • The upper allowable consumption level has not been established.
  • The physiological requirement for adults is 50 mcg / day (introduced for the first time).
  • The physiological need for children is from 10 to 50 mcg / day (introduced for the first time).

Cases in which the need for vitamin B7 increases by 20-50%:

  • excessive physical activity, professional sports (swimming, football, basketball, wrestling, alpine skiing, gymnastics, figure skating, hockey, cycling, mountaineering, fencing, rowing, running);
  • living in a cold climate, when the air temperature drops 35 degrees below zero;
  • high content of carbohydrates in the daily menu;
  • constant neuropsychic stress;
  • alcohol abuse;
  • dangerous burns;
  • with diabetes;
  • the presence of gastrointestinal diseases, which are accompanied by profuse diarrhea;
  • work with chemicals (carbon disulfide, arsenic, mercury);
  • long-term antibiotic treatment.

HYPOVITAMINOSIS AND HYPERVITAMINOSIS

Despite the prevalence of biotin in nature, a poor diet, an unhealthy lifestyle and other factors can lead to a lack of vitamin H in the body.

The reasons for the development of B 7 - hypovitaminosis:

  • therapy with antibiotic or sulfa drugs, which causes the death of beneficial microflora;
  • prolonged fasting or adherence to "hard" diets;
  • indigestion caused by atrophy of the mucous membrane of the stomach and small intestine;
  • hereditary disorders of metabolic processes in the body;
  • pregnancy proceeding with toxicosis;
  • insufficient intake of vitamin H in mother's breast milk (in newborns);
  • abuse of alcoholic beverages and sugar substitutes;
  • the presence of dysbiosis, which interferes with the normal synthesis of biotin;
  • regular intake of protein mixtures based on raw eggs (in professional sports).

For people at risk of developing B7 - hypovitaminosis, it is important to recognize the signs of biotin deficiency before they lead to depletion of the body and the development of diseases.

Symptoms of an acute coenzyme R deficiency:

  • constant peeling of the skin (especially around the mouth and nose);
  • fast fatiguability;
  • rashes on the hands, feet, or cheeks (dermatitis);
  • drowsiness;
  • decreased energy;
  • excessive dryness of the body;
  • loss of appetite;
  • swelling of the tongue or flattening of the "papillae" on it;
  • attacks of nausea, sometimes turning into vomiting;
  • muscle pain;
  • signs of anemia;
  • tingling or numbness in the limbs.

If signs of B7 deficiency are detected, it is important to immediately consult a doctor for the appointment of "biotin" therapy. If the nutrient deficiency is not controlled for a long time, this leads to complications in 50% of cases.

Secondary symptoms manifested against the background of chronic H-insufficiency:

  • decreased immunity, and as a result, the development of autoimmune diseases;
  • depletion of the body;
  • "Transformation" of dermatitis into psoriasis;
  • anxiety;
  • deep depression;
  • nervous disorders;
  • obsessive hallucinations;
  • lesions of the skin of the legs and arms;
  • drowsiness;
  • hypotension;
  • high concentrations of cholesterol and serum sugar;
  • anemia;
  • loss of appetite;
  • deterioration of the structure of hair and nails;
  • atopic dermatitis;
  • decreased vascular tone, as a result of which arterial hypotension develops;
  • dysfunction of amino acid and carbohydrate metabolism.

To prevent the risk of hypovitaminosis, the daily diet is enriched with foods or vitamin complexes containing biotin. At the same time, it is advisable to consume food supplements in a preventive dose (50 micrograms) on an ongoing basis.

Hypervitaminosis of biotin is rare because excess biotin is excreted in the urine. However, taking a large amount of the substance, exceeding 10 times the daily norm, leads to frequent urination and increased sweating.

SOURCES OF VITAMIN

Vitamin H is found in foods of plant and animal origin.

Thus, the largest amount of vitamin H is found in the liver, kidneys, eggs and legumes, and the smallest in citrus fruits and vegetables.

Due to the fact that biotin is resistant to high temperatures, after cooking foods rich in a beneficial compound, they retain up to 80% of the beneficial nutrient. However, it is important to remember that light and water destroy coenzyme R.

To preserve vitamin B7 in food, it is recommended to store them in a dark place, and rinse quickly under low pressure of running water before cooking.

The benefits of vitamins for the human body can hardly be overestimated. They participate in all life processes and ensure growth and development at all age stages. This article will focus on biotin.

Vitamin H, also called biotin or vitamin B7, belongs to the group of B vitamins and is an essential trace element for the normal functioning of the human body. Unlike other vitamins, the body's need for B7 is relatively small. Nevertheless, some processes in the human body cannot do without biotin. Its main functions are to improve the absorption of carbohydrates and regulate the production of insulin. A sufficient intake of biotin in the body helps to strengthen physical and mental strength, increase vigor and energy, preserve health and youth.

Vitamin H is a transparent crystal, perfectly soluble in alkali, almost insoluble in water. It does not tolerate thermal effects, it is destroyed by boiling. Adequate Biotin produced by the human intestinal microflora... But for this it is necessary that the intestines be clean of pathogenic microorganisms and decay products, which is virtually impossible in today's ecology. Therefore, at present, the bulk of vitamin B7 enters the body along with food.

The discovery of biotin

The world learned about biotin only in 1901. Then the scientist Wilderson described this substance in his works. He talked about the fact that it helps the development of yeast bacteria, and called it "bios", which is from the Greek. means life. Further studies of vitamin B7 were continued by the biologist Beteman in 1916, and laboratory rats helped him in this. The animals were fed raw eggs to provide them with proteins. However, soon, due to such a diet, the rodents began to deteriorate the skin, crawl out wool and deform muscle tissue. The symptoms disappeared as soon as the raw eggs were replaced by boiled yolks. Several years passed before scientists managed to isolate vitamin H from chicken yolks, which became a medicine for rats. It turned out that raw eggs contain a large amount of biotin, but the glycoprotein avidin prevents it from being absorbed normally. But in boiled eggs, this protein substance is absent. But in a free crystalline form, he was able to isolate it from the yolk of a chicken egg with Keglem in 1935. And then this substance was called biotin. In translation it means "necessary for life."

Cosmetologists call biotin "the source of beauty". Its molecular structure contains sulfur, which is essential for maintaining the healthy appearance of skin, hair and nails. With enough vitamin B7 in the body, the sebaceous glands work normally, the skin does not become inflamed, does not shine from excess fat, hair does not fall out, does not quickly turn greasy, nails remain strong, do not exfoliate.

Combining with the hormone insulin, vitamin H is involved in the breakdown of glucose, which is very important for normalizing blood sugar levels. Therefore, the use of biotin is recommended for people with diabetes. According to medical statistics, almost all patients who regularly take vitamin B7 supplements show positive changes in glucose metabolism. Also, biotin is a participant in the synthesis of hemoglobin, so that the process of hematopoiesis cannot do without it. This vitamin is part of the enzymes that form nucleic acids, muscle tissue and internal organs, promotes cell division and various biochemical reactions. Without vitamin H, carbon dioxide does not escape from the body, therefore, respiratory function is impossible. In short, biotin is involved in almost all metabolic processes. Therefore, its deficiency in the body is very noticeable.

Like all B vitamins, biotin is essential for the nervous system. It is he who supplies the nerve cells with the main nutrient - glucose. Therefore, with a decrease in the concentration of sugar in the blood, the psyche suffers: irascibility, nervousness, lethargy, sleep disturbances, tantrums become more frequent. It is also possible to note the property of vitamin H to break down proteins and lipids, destroy and remove excess fat accumulations from the body, which is very important for obese people.

What is the daily intake of vitamin H?

The daily intake of biotin is not exactly established, it depends on the age and physical condition of the person. An adult healthy person needs to receive daily from 30 to 50 mcg of vitamin with food. Usually food products completely cover this amount, and even exceed it. But pregnant women and nursing mothers require much more substance: from 100 to 120 mcg per day. Also, the need for vitamin H is increased in athletes and people taking antibiotics and hormonal contraceptives. The fact is that these medicines disrupt the work of the intestinal sections, where biotin is produced by bacteria. In such cases, additional intake of the vitamin in pharmaceutical form is necessary.

It should also be noted that in the female body, vitamin H is synthesized in smaller quantities, therefore, the female half needs it more.

What foods contain vitamin H?

Biotin is a fairly common vitamin found in many foods. It can be found in greatest quantities in animal products: pork, beef and chicken, liver and kidneys, milk and its derivatives, sea fish and canned fish. But the leader in vitamin H content is egg yolk.

To quickly increase the level of this vitamin in the body, it is recommended to consume more of the following foods:

  • dairy products with sufficient fat content;
  • nuts of all kinds;
  • boiled eggs;
  • legumes, soybeans, brown rice;
  • culinary yeast;
  • liver and heart;
  • sea ​​fish and caviar;
  • cauliflower;
  • greens, especially spinach, onions;
  • most fruits and berries.

Animal products are a good source of vitamin B7, but the problem is that the trace element is in a state associated with proteins, which means that it is poorly absorbed by the body. In addition, avidin in animal protein almost completely destroys biotin. Therefore, it is so dangerous to sit on a protein diet for a long time: it can completely destroy the intestinal microflora. This is especially true for heavyweight athletes. In order for the gut bacteria to produce enough vitamin H for it to be absorbed normally from food, you need to eat a balanced diet and regularly consume fresh vegetables and fruits. It is in plant products that biotin is in a free form that is not bound to proteins, which means it is optimal for intestinal absorption.

For biotin to be normal assimilated, magnesium is needed... Therefore, it is advisable to use these two substances in combination. Also, vitamin H combines very well with vitamins B12 and B9: it helps these microelements to have their effect on the body.

An important point: vitamin B5 blocks the action of biotin, so they cannot be taken at the same time.

How is vitamin H deficiency in the body manifested?

In healthy, nutritious and healthy people, biotin deficiency is extremely rare. Usually this problem overtakes alcoholics and heavy smokers. Also, a lack of vitamin H can manifest itself in people who are forced to use antibiotics and anticonvulsants.

Biotin deficiency affects primarily the appearance and mental state. With this pathology, the following symptoms are observed:

  • inflammation of the skin and mucous membranes, dermatitis;
  • baldness;
  • deformation of the nail plates;
  • a decrease in the level of hemoglobin in the blood, the occurrence of anemia;
  • loss of sensitivity of the papillae of the tongue;
  • lack of appetite, urge to vomit;
  • increased blood glucose levels;
  • the appearance of muscle pain;
  • blanching of the skin;
  • the occurrence of depression, nervousness, mental disorders;
  • being in a state of constant drowsiness, lethargy, chronic fatigue;
  • a sharp decrease in body weight;
  • sleep disturbance.

It is very difficult to determine exactly what the problem is precisely in the lack of biotin, because such conditions can be "disguised" as other diseases.

Can excess vitamin H occur?

An excess of biotin never occurs, even when consumed in large quantities with food or medicine. There are no side effects. In rare cases, an allergic reaction may occur, accompanied by a skin rash and shortness of breath. But it does not bear serious consequences and passes quickly.

When is vitamin H needed?

  • After treatment with antibacterial drugs that disrupt the normal intestinal microflora.
  • For problems with blood sugar levels.
  • With increased oily skin and hair.
  • Hair loss, thinning and delayed nail growth.
  • Decreased appetite, lethargy, increased fatigue, and trouble sleeping.
  • Alcohol abuse, which interferes with the production and absorption of the vitamin.

Now you know what vitamin B7 (biotin) is.

Vitamin H (biotin, vitamin B7)- a white crystalline substance, destructible at high temperatures and soluble in an alkaline aqueous medium. Biotin is involved in the formation of fatty acids and some biologically active substances.

Biotin can be produced by the intestinal microflora, but this is not enough to meet the body's need for vitamin H.

The average daily intake of biotin is 30-100 mcg. The daily requirement for biotin in pregnant and lactating women increases by 20 μg.

Functions of vitamin H in the human body

  • Biotin regulates blood sugar levels and is very important for carbohydrate metabolism. Vitamin H controls the processes of gluconeogenesis, being responsible for the participation of glucose in the metabolism.
  • Biotin plays an important role in protein absorption and fat burning.
  • Vitamin B7 contains sulfur, which is very important for the health of hair, nails and skin - biotin is also called the "beauty vitamin".
  • Vitamin H is essential for the normal functioning of the nervous system.
  • Biotin is involved in the synthesis of beneficial intestinal flora.

Symptoms of a lack and excess of vitamin H

In the body, with a shortage of biotin, the level of sugar and cholesterol in the blood rises, anemia develops, weakness, drowsiness, muscle pains, loss of appetite, depression, and nausea occur. Signs of a vitamin H deficiency include hair loss, dandruff, and excessively oily or excessively dry skin.

In case of hypervitaminosis of biotin in the human body, side effects are not observed. Even a long-term overdose of vitamin H does not cause any pathologies.

Vitamin H content in food

Interestingly, biotin is found in varying amounts in almost all foods. However, the maximum content of vitamin H is in nuts, boiled eggs, soybeans, liver and kidneys of large domestic animals, yeast, milk. Of vegetables, vitamin H is rich in spinach, cabbage, red beets. Biotin is also found in champignons and porcini mushrooms, in strawberry and blueberry leaves, in fruits.

Uses and interactions of vitamin H

For lovers of raw egg white, it is useful to know that it contains the antimatter biotin (avidin), which interferes with the absorption of vitamin H. In such cases, it is recommended to increase the daily intake of biotin and not to consume raw eggs and vitamin H at the same time.

Antibiotics and alcohol interfere with the synthesis and absorption of biotin.

To increase the activity of vitamin H, it is useful to take it together with magnesium.

Vitamin H or biotin (B7) is part of many enzymes that regulate fat and carbohydrate metabolism. In addition, beauticians call biotin a “beauty vitamin”. This is due to the fact that a lack of biotin causes brittle hair and nails and skin laxity, therefore biotin is included in many cosmetics.

Vitamin H was discovered through laboratory experiments on rats. From fresh egg whites, which were fed to rats, wanting to provide them with protein, the animals began to lose hair, and muscle and skin lesions appeared. When the rats were given boiled egg yolk, these symptoms disappeared. It took scientists almost two decades to isolate biotin from the yolk - the very substance that restored the health of the skin and hair of animals. Biotin dissolves in water if the pH is high and breaks down at very high temperatures.

Biotin action

Biotin improves the condition of the skin, hair and nails, increases activity, participates in the regulation of cholesterol levels, indirectly participates in the mechanisms of regulation of blood glucose levels, improves appetite, and accelerates growth in children.

Vitamin H is involved both in the production of various enzymes and in the work of enzymatic systems in general. Biotin is involved in the metabolism of fats, proteins and carbohydrates. Vitamin H is essential for the functioning of the immune system, the nervous system, as well as for the beauty and health of the skin. Thus, biotin is necessary for the human body, as it strengthens nails, makes the skin and hair healthy and beautiful. Based on this property, vitamin H is included in various dietary supplements (biologically active additives) and preparations used in cosmetology.

Energy from fats, carbohydrates and proteins is transformed with vitamin B7 (vitamin H), which has a positive effect on diabetes. Studies show that a lack of biotin manifests itself precisely in diabetes mellitus.

Vitamin H is synthesized in the intestines with the help of microflora, normalizes the functioning of the intestines and stomach. Biotin also has a lipotropic effect.

Daily requirement for vitamin H:

In the methodological recommendations MR 2.3.1.2432-08 on the norms of physiological needs for energy and nutrients for various groups of the population of the Russian Federation dated December 18, 2008, the following data are given:

Physiological need for Vitamin H, mcg per day:

A balanced diet is able to provide the required amount of biotin in the body.

Biotin, like vitamin B1, is easily absorbed by the body, but does not accumulate in it. In addition, excessive consumption of alcohol and coffee interferes with the absorption of biotin. The presence of overheated fats in food (fried and deep-fried dishes) also impairs the absorption of biotin.

Do not forget that raw chicken eggs contain the substance avidin, which interferes with the absorption of biotin. There are cases when the daily consumption of raw eggs caused severe forms of vitamin deficiency.

However, when heated, avidin decomposes, so eating boiled eggs does not interfere with the absorption of biotin. Lovers of raw eggs can be recommended to drink quail eggs. There is very little avidin in them, and there are more vitamins than in chicken.

Lack of biotin:

Lack of biotin occurs in the following diseases: suppression of intestinal microflora, gastritis (anacid), and other intestinal diseases. Signs of vitamin H deficiency are peeling of the skin, the development of dermatitis on the skin of the cheeks, arms, and legs.

Excess biotin:

Biotin overdose is not observed even with the appointment of large doses, including in young children and pregnant women.

Sources of Biotin:

Biotin is found in varying amounts in many foods and is produced by the intestinal microflora.

Most biotin is found in the following foods:

Sources of animal origin: liver, egg yolk, milk, lamb, salmon fish and their caviar.

Plant Sources: Yeast, tomatoes, soybeans, spinach, green peas (fresh), mushrooms, bran and wholemeal flour.

Biotin is resistant to acids and alkalis, it is not afraid of heat and oxygen.
