Vitamin B2 in what. Vitamin B2. Causes and signs of deficiency

In fact, we all know that the body needs vitamins. But not every person has information about what they are and what exactly they do in our body. So, vitamins are actually tiny organic substances. They are needed for the full accomplishment of a variety of processes, the production of enzymes and hormones. Such particles should mainly be ingested with food. Just such substances include vitamin B2. We will tell you why the body needs vitamin B2, and also in what food it is contained.

So, vitamin B2 is classified by doctors as riboflavin. This is an extremely important substance for our body, like almost all B vitamins.

Why does our body need vitamin B2??

This vitamin is considered the health vitamin. Its deficiency is quite difficult to recognize in time, but at the same time it can cause quite a lot of discomfort and even shorten life expectancy. Many experts refer to vitamin B2 as a skin vitamin. And those who want to have elastic, young, smooth and healthy skin should definitely saturate the diet with products that contain such a substance. In addition, the condition of the skin, which is completely natural, is directly related to the condition of all internal organs.

Vitamin B2 is necessary for our body for a full metabolism. Scientists say that it makes metabolic processes more intense, and takes an active part in the processing of proteins, as well as fats with carbohydrates.

Riboflavin is essential for making enough red blood cells. Therefore, its sufficient consumption has a positive effect on the blood formula. Another such vitamin is very necessary for the immune system for the full synthesis of antibodies.

Vitamin B2 is involved in the delivery of oxygen to all cells of our body. Such a substance allows the cells of the skin, hair, and nails to be saturated with a particularly significant amount of oxygen. In addition, riboflavin is used to regulate growth processes.

Sufficient intake of vitamin B2 has a positive effect on the functioning of the visual apparatus. Like the well-known vitamin A, riboflavin is necessary to maintain normal twilight vision. And yet such a substance effectively reduces eye fatigue and even helps to avoid the development of cataracts.

The systematic and sufficient intake of riboflavin in the body has a positive effect on the health of the mucous membranes of the digestive tract. Such a vitamin is also necessary for other mucous membranes, so it shows the ability to reduce the negative impact of various aggressive substances on the respiratory tract.

In addition, without riboflavin, it is impossible to fully assimilate tryptophan, which becomes niacin inside our body. And the most valuable quality of vitamin B2 is the ability to activate the transformation of pyridoxine (better known as vitamin B6) into the state of the active form.

At the initial stage, the lack of riboflavin is manifested by rather unexpressed symptoms, but readers of "Popular about Health" should not leave them unattended. It is better to listen carefully to the body, so as not to disentangle more serious health problems later.

So, with a deficiency of vitamin B2, there is a slight decrease in appetite and even weight loss. The person may experience feelings of weakness. Another similar condition leads to the development of headaches, and to impaired twilight vision. In addition, a lack of riboflavin can be manifested by pain in the eyes. Quite often there is discomfort and even pain in the corners of the mouth, as well as on the lower lip.

If riboflavin deficiency becomes more pronounced, this leads to the formation of cracks and crusts in the corners of the mouth, as well as to inflammatory processes in the mucous membranes of the mouth. Severe deficiency causes seborrheic dermatitis of the nose and lip folds. A possible manifestation of such a pathological condition is skin lesions, various dermatitis and alopecia (hair loss), and digestive disorders are also possible. A severe lack of riboflavin leads to changes in the cornea, increased sensitivity to light, the development of conjunctivitis or blepharitis. There are also violations of night rest, dizziness and reaction disorders. Possible growth retardation.

Among other things, a deficiency of riboflavin leads to impaired absorption of iron, and to a weakening of the thyroid gland.

Vitamin B2 in products

It is believed that especially a lot of vitamin B2 is present in the composition of yeast (beer dried, baker's fresh and baker's dried). Different types of meat act as sources of such a substance - fatty pork and beef, as well as veal and lamb. A certain amount of riboflavin is found in milk and various dairy products. In addition, mackerel is especially rich in it. Vitamin B2 is found in oatmeal, buckwheat, almonds and flour. A certain amount of this substance is found in chicken eggs, cocoa and dry legumes, as well as peanuts. In addition, spinach and potatoes can be considered a source of riboflavin.

In some cases, doctors insist on additional intake of vitamin B2, in addition to that received by the body from food. In this case, it can be purchased at a pharmacy and used as an additive to the main diet.

Everyone is aware of the benefits of vitamins, but rarely does anyone eat properly and balanced. A large number of people of different age categories experience a lack of B vitamins. This article will tell you which foods contain vitamin B2 and how you can maintain its balance in the human body.

Vitamin Benefits

B2 (vitamin, which is also known as riboflavin), is actively involved in the course of vital processes in the human body. It is required for the full-fledged formation of certain hormonal substances and erythrocyte blood cells.

B2 is a vitamin that helps the organs of vision adapt to the dark. It is the guarantor of good human vision, makes it sharper, enhancing color and light perception.

Riboflavin is involved in the breakdown of proteins, fats and carbohydrates, is an integral part of a large number of enzymes. According to experts, normal growth and constant tissue renewal are impossible without this vitamin.

B2 is a vitamin that positively affects the health of the liver, skin and nervous system of a person.

Signs of riboflavin deficiency

The main symptom of vitamin B2 deficiency is the presence of peeling on the mucous membranes, wings of the nose and ears. A sign of this disease is also considered to be the presence of cracks in the corners of the mouth, causing pain.

With a deficiency of riboflavin, patients may experience discomfort in the eyes. They begin to pursue itching, tearing and redness of the organs of vision. The red color of the tongue is also a symptom of riboflavin deficiency.

It is important to know that during heat treatment, the amount of this vitamin in foods decreases. Riboflavin is not able to be absorbed and processed by the human body if combined with alkalis. Vitamin B2 in foods is also negatively affected by sunlight.

The norm of vitamin B2

The daily rate of riboflavin directly depends on the characteristics of the human body and its gender. There are groups of people who feel the need for an increased amount of this vitamin. These include women who are expecting a baby or breastfeeding a child, and people who drink alcoholic beverages.

The body strongly requires vitamin B2 when eating foods saturated with fats and carbohydrates, when using certain contraceptives, as well as sudden changes in temperature.

If you have symptoms that indicate a deficiency of riboflavin, you should seek help from specialists. They will help to identify the true causes of this violation and recommend means to eliminate it.

The role of a balanced diet in the fight against vitamin B2 deficiency

In order to prevent riboflavin deficiency and to combat it in the initial stages, it is recommended to adjust the diet. Having an idea of what kind of food contains vitamin B2 in sufficient quantities, it is possible, without resorting to special means, to replenish the supply of this vitamin in the human body.

50 grams of products that include a record amount of riboflavin in their composition are able to saturate the body with a daily dose of this vitamin. In this article, we will try to answer the question of which foods contain the largest amount of vitamin B2, because it is mandatory to get it with food.

Riboflavin Rich Foods

There is an opinion that a lot of vitamin B2 is found in vegetables and fruits. However, they do not top the list of foods with a record content of this vitamin. And the list looks like this:

Yeast (the amount of riboflavin depends on the form of their preparation).
Liver (a large amount of the vitamin is found in the liver of elk, walrus, fur seals, as well as in lamb liver).
Hemp seed, cleaned.
Dried spirulina.
Beef kidneys.

The kidneys and liver of a large number of animals play the role of a kind of storehouse of vitamins. They are the richest sources of riboflavin. People living in the North eat mostly meat and offal, and this saves them from vitamin deficiencies.

Vitamin B2 is also saturated in certain food concentrates, however, they are not considered as the main sources of this vitamin. It is hard to even imagine that it is realistic to include 100 grams of these concentrates in your diet.

This also applies to the liver and kidneys of various exotic animals. Eating elk or walrus liver every day is just as problematic as spirulina, especially since vitamin B2 is found in foods that are easier to purchase and prepare.

Vitamin B2 (which foods contain)

It is believed that vitamin B2 deficiency is not experienced by people who eat the following foods:

Meat products and by-products, as well as products prepared from them.
Dairy.
Cereals, slightly processed (rice, buckwheat, oatmeal).
Mushrooms.
Bread products with bran.

It is important to know that B2 is a vitamin that cannot accumulate in the human body. Excess consumption of foods containing riboflavin does not guarantee the formation of a supply of this vitamin for the following days. Vitamin B2 leaves the body with urine.

A deficiency in this vitamin can be a side effect of ill-conceived, strict diets. Vegetarians who do not rely on plant sources of this vitamin are also susceptible to it. They are advised to eat almonds, mushrooms and berries or to replenish vitamin B2 with tablets.

Pregnant women, in order for the child to develop well and be born healthy, should saturate their body with the necessary amount of riboflavin. The fair sex is recommended to introduce the vitamin into the body with food, and not with the help of expensive medicines.

Vitamin B2 tablets

"Riboflavin" in the form of tablets, experts advise to use:

For the prevention and treatment of vitamin B2 deficiency.
With dermatological diseases.
in the treatment of radiation sickness.
As a means of healing wounds and scratches.
With a lack of iron in the body.
In case of malfunctions in the digestive tract due to a lack of riboflavin.
In diseases of the liver: in combination with other drugs.
In the prevention and treatment of diabetes.

"Riboflavin" in tablets should be used according to the prescriptions of doctors. The daily dosage of drugs directly depends on the age category of patients.

Vitamin B2 in tablets has almost no contraindications for use. It is not recommended to take it in the presence of individual intolerance in the patient. Riboflavin tablets should be taken two hours before a meal with plenty of water.

Vitamin B2 is one of the most important vitamins necessary for the human body. To maintain good health, it is important to control the daily intake of the daily intake of this vitamin in the body.

B2 is a vitamin that saturates the body not only with health, but also with beauty. In order to have skin that attracts attention with its youth, smoothness and elasticity, it is recommended to include foods that serve as sources of this vitamin in the diet.

An element such as vitamin B2, for which the body needs, can be understood if you familiarize yourself with the information in more detail about the processes in which this useful trace element is involved.

Vitamin B2 or, as it is also called, Riboflavin is a water-soluble vitamin, which in its natural state is presented in the form of yellow oblong crystals, characterized by a bitter taste.

This element cannot be found in free form in nature. It is present only in solutions that function in a living organism.

Importance of B2 for health

Vitamin B2 plays an invaluable role in human health. It plays an essential role in such processes of the body as the transformation of amino acids, the production of other useful trace elements, etc. Without this element, adequate work of all organs is impossible.

Without this trace element, the process of synthesizing some hormones and red blood cells is impossible. Vitamin protects the retina from the negative effects of ultraviolet rays, improves visual acuity and adapts to the eyes in the dark.

This vitamin necessary for the body is actively involved in the production of stress hormones. As you know, due to constant stress and pressure on the nervous system, the content of this vitamin in the body is reduced, as a result of which the latter becomes unprotected. Therefore, it is very important in case of a nervous breakdown and a state of stress to consume as many foods rich in riboflavin as possible.

Riboflavin allows adequate breakdown of proteins, fats and carbohydrates. For those people who play sports or whose work is associated with physical overstrain, the vitamin is needed as a so-called fuel transformer, since B2 converts the consumed fats and carbohydrates into energy.

Riboflavin does an excellent job with the issue of tissue regeneration and growth. It has the most positive effect on the central nervous system, as well as the liver and mucous membranes. This vitamin is very important for the proper development of the fetus during pregnancy.

Daily intake and consequences of vitamin deficiency in the body

Such a value as the daily norm of riboflavin is a variable value and depends on such factors as, for example, gender, age, etc.

However, it has been established that the average daily requirement for a person is:

men - 1.7 - 1.8 mg;
women - 1.3 - 1.6 mg;
children - 0.5 - 1.5 mg.

An adult can get the required daily allowance by eating 2 eggs or 300 grams of cottage cheese during the day. Thus, a balanced diet provides the body with the amount of vitamin necessary.

However, in practice there are deviations from these norms, which is due to such circumstances as taking hormonal medications, excessive consumption of alcoholic beverages, as well as high physical exertion. And it is quite natural that it will be much better for the body if a person receives riboflavin by consuming food, and not taking expensive drugs.

Symptoms and Causes of Riboflavin Deficiency

In medicine, a condition in which there is a lack of vitamin B2 in the patient's body is called hyporiboflavinosis. Signs of such a condition can manifest themselves both externally and affecting the work of internal organs and systems. At different stages of the development of hypovitaminosis, the patient will experience the following symptoms of vitamin deficiency in the body:

drying and cracking of the skin of the lips;
loss of appetite, a state of weakness, the appearance of headaches and loss of strength;
various skin pathologies, for example, rashes or itching, which is caused by a disorder in the functioning of the nervous system;
fragility and hair loss;
the development of an inflammatory process in the oral cavity;
decreased visual acuity;
disorders in the digestive system;
sleep disturbance, dizziness, lethargy of brain activity caused by starvation of blood vessels; - burning pain in the arms and legs, the appearance of convulsions;
exhaustion of the body, stunted growth, which is especially characteristic and dangerous for children; - slow wound healing;
development of photophobia.

If we talk about the reasons that provoke a vitamin deficiency in the body, then in addition to taking certain drugs, hypo- or hyperfunction of the thyroid gland, as well as a number of other pathologies, can cause such a condition.

In addition, vitamin B2 is destroyed if you defrost vegetables and meat products for half a day in the light. However, useful elements in products are stored in the refrigerator. The loss of useful properties of food can be avoided if you refuse to take medications, put frozen vegetables or meat immediately in boiled water or defrost them, for example, in a microwave, after wrapping them in food foil.

Replenishment of vitamin B2 deficiency

As noted earlier, today the pharmaceutical industry offers a huge selection of drugs that allow you to fill the daily requirement of a vitamin in the body.

As for the instructions for the use of these tablets, it is individual for each drug. At the same time, it must be taken into account that the specifics of taking a tableted vitamin will depend on the need for it in each patient.

It is also worth noting that the procedure for taking riboflavin for various pathologies will differ significantly from the procedure for taking the drug for prevention purposes.

However, as recommended by nutritionists, it is much better to get vitamin B2 from natural products. In this regard, the best way to provide the body with the necessary amount of riboflavin is a proper and balanced diet, which consists of products of plant and animal origin. The maximum amount of the indicated vitamin is present in products such as milk, pine nuts or fresh meat.

Thus, riboflavin or vitamin B2 is necessary for the body to provide a huge number of processes in the body of a biochemical nature. The specified element is key in ensuring the work of the digestive, cardiovascular and nervous systems. And in order for each person to feel great, one should receive the required daily dose of the indicated element.

Vitamin B2 (riboflavin) is one of the most important water-soluble elements for humans, an activator of biological processes. This compound is poorly soluble in alcohol and water with an elevated pH level, and is stable in an acidic environment. Riboflavin is destroyed by exposure to sunlight and alkali.

Functions of vitamin B2 in the body:

Increases and accelerates metabolic processes in the body;
Participates in protein, carbohydrate and fat metabolism;
Necessary for the formation of blood antibodies and bodies;
Promotes cell growth and respiration;
Oxygenates the cells of the skin, nails and hair;
Improves vision, prevents the development of cataracts;
Has a positive effect on the mucous membranes of the digestive tract;
Accelerates the activation of pyridoxine (B6) in the body.

With the help of vitamin B2, skin diseases, sluggish healing wounds, eye diseases, disorders of the gastrointestinal tract, diabetes, anemia and cirrhosis of the liver are treated and prevented.

Riboflavin was isolated from the B group of vitamins in 1933 as a heat-resistant element from a yellow-colored substance.

Signs of shortage

A reduced content or absence of riboflavin in the body leads to the development of hyporiboflavinosis, which eventually develops into ariboflavinosis, which is characterized by damage to the skin, mucous membranes of the mouth, nervous system and organs of vision.

With a lack of vitamin B2, there are:

Decreased appetite and body weight;
General weakness and headaches;
Burning sensation on the skin;
Cutting in the eyes and impaired visibility in the dark;
Pain in the corners of the mouth and lower lip.

A long-term deficiency of this element in the body leads to sad consequences: acne stomatitis, inflammation of the mucous membranes of the oral cavity, seborrheic dermatitis of the labial folds and nose, hair loss and skin lesions, digestive disorders, conjunctivitis, mental retardation, and growth retardation.

Hypovitaminosis of this element in the body primarily affects the state of the brain tissue, as well as the absorption of iron and the state of the thyroid gland.

Effects

Vitamin B2 is consumed very quickly in the human body, as a result of which daily replenishment of this element is mandatory. To prevent the occurrence and development of diseases against the background of a lack of riboflavin, you should try to keep as much vitamin B2 in food as possible or fill the daily requirement by taking vitamin complex preparations.

A long-term deficiency of riboflavin leads to the following consequences:

Burning pains in the legs;
Keratitis and cataract;
Stomatitis and glossitis;
Anemia and muscle weakness.

Overdose

An excess of riboflavin in medical practice is a rare case, and its excessive introduction into the body does not have any unpleasant consequences, except for itching, numbness and slight burning, but these symptoms quickly disappear.

Vitamin B 2 or riboflavin is called the vitamin of youth and beauty. A decrease in the concentration of riboflavin in the body immediately affects the condition of the skin, and a long-term deficiency of vitamin B 2 can cause a shortening of life. Already after 4 months, the lack of riboflavin leads to changes in the functioning of internal organs, so it is very important to know the symptoms and causes of ariboflavinosis.

The role of vitamin B2 in the human body

Riboflavin - vitamin B2, lactoflavin or vitamin G - one of the most important B vitamins, it does not accumulate in the human body, so a daily intake of riboflavin with food is necessary. In small quantities, vitamin B2 is able to be synthesized in the small intestine, but it is not enough for the normal functioning of the body.

Riboflavin is a biologically active substance that is a catalyst for many chemical reactions that occur in the body.

Among the most important functions of vitamin B2 are:

Participation in hematopoietic processes- Vitamin B2 is involved in the regulation of the synthesis of hemoglobin and red blood cells. Also, riboflavin is necessary for the normal absorption and assimilation of iron, which is part of hemoglobin;
Protecting the body from infections Riboflavin is involved in the synthesis of antibodies and macrophages. In addition, a lack of vitamin B2 causes suppression of the immune system;
Participation in all kinds metabolism- riboflavin serves as an activator of the metabolism of carbohydrates, proteins and fats;
Participation in glycogen synthesis- Without riboflavin, the process of formation of complex carbohydrates from blood glucose is impossible. A lack of vitamin B 2 can cause an increase in the concentration of glucose in the blood;
Reducing stress levels- nervous strain, stress and increased mental stress cause an increased consumption of riboflavin reserves, and with a deficiency of this substance, nerve cells face exhaustion. Riboflavin is used in the treatment of anxiety, insomnia, Alzheimer's disease and epilepsy;
Activation of vitamins- riboflavin is necessary for the activation of vitamin B6, B9, K and a number of others;
Influence on the condition of the skin and mucous membranes- with a lack of vitamin B2, epithelial cells age faster and are destroyed. A sufficient amount of vitamin helps to avoid inflammation of the mucous membranes of the mouth, intestines and urinary organs, as well as skin diseases such as eczema, dermatitis and acne;
Regulation of thyroid function- B vitamins are involved in the synthesis of hormones and their deficiency can cause dysfunction of this organ;
Participation in redox processes- Riboflavin provides ATP synthesis and increases vascular tone. Vitamin B2 helps fight coronary heart disease, vasospasm and is used to prevent myocardial infarction;
Eye protection from ultraviolet radiation - together with vitamin A, riboflavin protects the retina from UV radiation, overwork and prevents clouding of the lens and the formation of cataracts;
Respiratory protection from toxins - with a sufficient concentration of vitamin B 2, the respiratory system is less susceptible to toxins, so taking this vitamin is recommended for smokers, patients with bronchial asthma and those whose professional activities are associated with the inhalation of polluted air.

Vitamin B2 is necessary for the normal growth and development of the fetus and the growing organism, its deficiency in childhood can cause a lag in mental or physical development, a decrease in immunity and the appearance of pathologies of internal organs.

Lack of vitamin B2 in the body

Vitamin B2 is widely distributed in nature, it is synthesized in the body of artiodactyl mammals and partially in the human intestine. But the main part of riboflavin we get from food - meat and dairy products, vegetables and fruits.

According to doctors, up to 90% of the Russian population suffers from a slight deficiency of riboflavin, children, adolescents, pregnant and lactating women and older people are at risk. An increased need for riboflavin is also among those who are engaged in mental work associated with overexertion of the nervous system.

Severe riboflavin deficiency can be caused by:

Restriction in the diet of meat and dairy products - vitamin B2 in vegetables and cereals is easily destroyed during heat treatment, therefore, with the complete exclusion of meat and dairy products, riboflavin contained in vegetables and fruits may not be enough;
Inflammatory bowel diseases - irritable bowel syndrome, chronic enteritis, enterocolitis or dysbacteriosis most often lead to a deficiency of B vitamins, including riboflavin. Due to inflammation of the mucous membrane, vitamin B2 is not synthesized and is not absorbed in sufficient quantities;
Taking medications - antidepressants, antianginal drugs, oral contraceptives and some other drugs cause increased excretion of riboflavin from the body or prevent its absorption and assimilation in the intestine;
Thyroid disease - thyroid dysfunction also causes a deficiency of riboflavin in the human body;
Alcohol and tobacco use - Alcohol and nicotine make it difficult for riboflavin to be absorbed in the intestines.

Vitamin B2 deficiency symptoms

With a slight deficiency of vitamin B2, a person experiences constant fatigue, his appetite disappears, weight decreases, sleep problems, headaches, vision problems, cracks in the corners of the mouth, stomatitis and skin diseases appear.

If the lack of vitamin B2 continues for more than 3-4 months, more serious health problems appear:

Indigestion - the patient's appetite worsens, abdominal pain and stool upset occur - constipation alternates with diarrhea;
Diseases of the organs of vision - the eyes get tired easily, often become inflamed, the patient may develop chronic conjunctivitis or cataracts;
Diseases of the nervous system - with a lack of riboflavin, the tissues of the nervous system experience a lack of oxygen and nutrients, which increases their sensitivity to negative environmental influences and increases the risk of developing depression, epilepsy and encephalopathy. Neurological disorders also occur - weakness in the muscles, pain in the limbs, impaired coordination of movement and slowing down of reactions;
Anemia - with a lack of riboflavin, iron is poorly absorbed, and the concentration of hemoglobin in the blood decreases;
Decreased immunity - due to a decrease in the body's defenses, patients exacerbate chronic diseases and easily develop viral and bacterial infections.

Excess riboflavin

Vitamin B2 is easily destroyed and excreted from the body with urine, therefore, under natural conditions, there can be no excess of riboflavin. An increase in the concentration of vitamin B2 very rarely occurs when taking synthetic drugs or with severe renal failure.

Sources of Vitamin B2

Every day, an adult needs 1-3 mg of riboflavin, and the need for the vitamin grows in proportion to emotional stress - the more often you have to be nervous during the day, the more vitamin B2 is spent.

You can get the required amount of vitamin from the following foods:

meat and dairy products - the leaders in the content of riboflavin are liver, lean meats, eggs, kidneys, milk, sour cream and cottage cheese;
cereals - less riboflavin in buckwheat, barley, wheat groats, wholemeal flour;
vegetables - fresh cauliflower, peas, turnips, spinach, greens also have enough vitamin B2.

You can fully meet the needs for B vitamins with regular intake of brewer's yeast, so the content of vitamin B2 in 100 g of the product is 200-300 mg.
