Vitamin b2 message. Routes of entry and metabolism. The effect of vitamin B2 on the body

Physico-chemical properties of vitamin B2

B2 is yellow-orange needle-shaped crystals collected in large flasks, has a bitter taste. Riboflavin is stable in acid and is rapidly destroyed in alkaline environment. Tolerates heat well.

Riboflavin is biologically active substance playing important role in maintaining human health (kalorizator). Biological role riboflavin is determined by the inclusion of its derivatives - coenzymes - in the composition a large number the most important redox enzymes.

Daily requirement for vitamin B2

The decrease in the level of vitamin B2 in the body is facilitated by: weather, great psychological and physical stress, reception oral contraceptives, bad job thyroid gland, excessive alcohol consumption.

Vitamin B2 is essential for the formation of red blood cells, antibodies, growth regulation and reproductive functions in the body. It is also essential for healthy skin, nails, hair growth, and overall overall health, including thyroid function.

The most important functions of vitamin B2:

• Participates in carbohydrate, protein and fat metabolism;
• Participates in the synthesis of glycogen;
• Helps absorb the iron needed to create new reds blood cells;
• Strengthens immunity and defense mechanisms organism;
• Plays an important role in work nervous system, helps in the treatment of diseases such as: epilepsy, Alzheimer's disease and increased anxiety;
• Needed to save normal state mucous membranes of the mouth and intestines;
• Regulates the function of the thyroid gland;
• Contributes to normal light and color vision, protects the retina from excessive exposure to ultraviolet rays, reduces eye fatigue, provides dark adaptation, improves visual acuity and plays an important role in preventing cataracts;
• Helps with acne, dermatitis, eczema;
• Accelerates the healing of damaged tissues;
• Reduces the effects of toxins on the lungs and Airways.

Harmful properties of vitamin B2

There is only one harmful property of vitamin B2 - a possible fatty liver. But this can happen only in the case of the absorption of vitamin complexes in uncontrolled regimes and the abuse of various dietary supplements.

Vitamin B2 absorption

Vitamin B2 is quite well absorbed from food, but it has some peculiarities. From vegetables, it is absorbed better if they are previously exposed to heat treatment. People using B2 as food additive, we must remember that the vitamin is well absorbed when there is enough food in the stomach. If taken on an empty stomach, riboflavin will be less absorbed. Also, if a person is sitting on strict diet and eats very little, this reduces the absorption of B2.

External manifestations of riboflavin deficiency in humans are lesions of the mucous membrane of the lips with vertical cracks and desquamation of the epithelium, ulceration in the corners of the mouth, swelling and redness of the tongue, seborrheic dermatitis on the nasolabial fold, wings of the nose, ears, eyelids. Often, changes in the organs of vision also develop: photophobia, vascularization of the cornea, conjunctivitis, keratitis and, in some cases, cataracts (calorizator). In some cases, with beriberi, anemia and nervous disorders, manifested in muscle weakness, burning pains in the legs, etc.

The main causes of riboflavin deficiency in humans are insufficient intake and, which are the main sources of this vitamin; chronic diseases gastrointestinal tract, taking medications that are riboflavin antagonists.

Too much vitamin B2 in the body

The human body does not store riboflavin and any excess is excreted in the urine. With an excess of riboflavin, urine turns bright yellow. Signs of excess vitamin B2: malabsorption, increased tendon reflexes, cerebral insufficiency, dizziness, rarely itching, numbness, burning or tingling.

Interaction of vitamin B2 (Riboflavin) with other substances

For more information about vitamin B2, see the video clip " Organic chemistry. Vitamin B2"

In today's article, I will tell you about such a useful and essential vitamin for a person like Vitamin B2 and its importance in our daily life. So…

Vitamin B2, or "Riboflavin" ( English Riboflavin) - one of the most important water-soluble vitamins, a coenzyme of many biochemical processes.

Other names for vitamin B2: lactoflavin, E101 (food additive).

Synonyms: ovoflavin, hepatoflavin, verdoflavin, uroflavin, beflavin, beflavit, betavitam, flavaxin, flavitol, lactobene, ribovin, vitaflavin, vitaplex B2. Most of these names indicate the source from which this vitamin was initially isolated, i.e. milk, eggs, liver, plants, urine.

Vitamin B2 is necessary for the formation of red blood cells, antibodies, for the regulation of growth and reproductive functions in the body. It is also essential for healthy skin, nails, hair growth, and overall health of the entire body, including thyroid function.

Riboflavin- collected in druze needle-like crystals of yellow-orange color, with a bitter aftertaste. Riboflavin is a derivative of the heterocyclic compound isoalloxazine linked to the polyhydric alcohol ribitol.

Vitamin B2 is poorly soluble in water (0.11 mg/ml at 27.5°C) and ethanol. Insoluble in acetone diethyl ether, chloroform, benzene. Riboflavin is stable in an acidic environment and rapidly decomposes in an alkaline environment and under the action of light.

Systematic name of riboflavin: 6,7-Dimethyl-9-(D-1-ribityl)-isoalloxazine.

Chemical formula of thiamine: C17H20N4O6.

Functions of Vitamin B2

Vitamin B2 intensifies metabolic processes in the body, participating in the metabolism of proteins, fats and carbohydrates. Riboflavin is essential for the formation of red blood cells and antibodies, for cell respiration and growth. It facilitates the absorption of oxygen by the cells of the skin, nails and hair. Improves the condition of the organ of vision, taking, along with, participation in the processes dark adaptation, reduces eye fatigue and plays a big role in preventing. Vitamin B2 has positive impact on mucous membranes digestive tract. Riboflavin minimizes negative impact various toxins to the respiratory tract. In addition, vitamin B2 protects the skin from microbes, provides visual acuity, regenerates and restores body tissues. Riboflavin is necessary for the metabolism of tryptophan, which is converted in the body into.

One of the most valuable qualities of riboflavin is its ability to accelerate the conversion of pyridoxine - vitamin B6 - into its active form in the body.

Reserves of riboflavin in the body

Dietary flavins are released in the stomach under the influence of acids and then absorbed in the upper part of the stomach. small intestine through transport mechanism with bile salts. In the cells of the intestinal mucosa, riboflavin is converted to the coenzyme form of flavin mononucleotide (FMN). In the transport system, it binds to plasma albumin and is transported to the liver, where it is converted to another coenzyme form, flavin adenine dinucleotide (FAD), and binds to special proteins called flavin proteins.

Riboflavin enters tissues mainly in the form of FAD, but its concentration in tissues is not high and it is not stored there in large quantities. Liver, main body storage, contains about a third of the total content of riboflavin in the body. The level of riboflavin in blood plasma reflects the amount of riboflavin received with food and is normally 30-40 μg / l. A significant concentration of riboflavin is found in retinal tissues, but its function there is unknown. Riboflavin is excreted mainly in the urine, which gives it a yellow color.

A small amount of riboflavin is also excreted along with sweat and bile. The riboflavin found in feces is mainly the result of intestinal bacteria. In women during breastfeeding, about 10% of the absorbed riboflavin is excreted into milk.

The need for riboflavin increases with increased physical activity, as well as when taking oral contraceptives. The systematic use of alcohol deforms the mechanism of absorption of vitamin B2, therefore, people who abuse alcohol have an increased need for riboflavin.

Vitamin B2 dosages

A lack of riboflavin can also lead to impaired iron absorption and weaken the thyroid gland.

The amount of vitamin B2 in some foods

You need to know!

Cottage cheese can be different: the softer it is, the more whey is left in it, the more it contains vitamin B2.

Milk in a glass container in daylight, for example by a window, loses its most the vitamin B2 it contains. In sunlight for 2 hours, milk in transparent bottles loses 50% of riboflavin.

When we boil peas and drain the water, there is no riboflavin left in the finished dish at all. Always cover the utensils in which food is cooked. Otherwise, many vitamins are oxidized. Do not throw away the water in which the potatoes were boiled: it contains a lot of riboflavin and other B vitamins. Keep in mind that part of the vitamin B2 is lost when vegetables are washed in in large numbers water, part - during storage, even in the refrigerator (about 1% per day). This suggests that you do not need to soak vegetables for a long time and buy them in large quantities.

Important! As we already know, riboflavin is destroyed when exposed to daylight. Based on this, it is necessary to store products containing vitamin B2 in a dark place, and never leave it in the light. Also, try to use these products in natural form, without heat treatment, and if you have to cook, then do it quickly, under the lid. By the way, for cooking, with minimal loss vitamins, you can use a double boiler.

Interaction of vitamin B2 with other substances

Antihypertensive drugs (angiotensin-converting enzyme blockers) increase the conversion of riboflavin to coenzyme forms.

Antipsychotics (large tranquilizers - chlorpromazine, propazine, tizercin, teralen, meterazine, fluorophenazine) inhibit the metabolism of riboflavin, in particular, chlorpromazine blocks the conversion of riboflavian into one of the coenzyme forms.

Peripheral vasodilators block the conversion of riboflavin to coenzyme forms.

Drugs that regulate thyroid function (thyreodin) enhance the conversion of riboflavin to its coenzyme forms.

Riboflavin promotes iron absorption, mobilization and storage.

Vitamin B2 also promotes absorption, and.

Vitamin B2 is needed for normal operation detoxification system of the body together with (nicotinic acid).

Greetings, my wonderful readers. I propose to continue our fascinating journey into the "kingdom" of vitamins. Our guest today will be Riboflavin - aka vitamin b2. This element has 20 names in total. Just a real "chameleon" 🙂

Vitamin B2 is important element, acting as an antioxidant. However, the most valuable value for the organism is not the B2 element itself, but its derivatives. These are flavin mononucleotide and flavin adenine dinucleotide. With the participation of these complex substances most of the redox reactions in the body.

Without these elements, many biochemical processes cannot occur properly. They are needed for:

• digestion of food;
• tissue growth;
• brain activity;
• contraction of muscle tissue;
• amplification of action , and ;
• production of hemoglobin;
• invaluable for hair (provides their growth);
• normalization of cardiac activity.

supports good mood, helps to feel a surge of strength and cheerfulness;

In addition, this vitamin is responsible for maintaining healthy cells helps to increase energy levels and feel energized and energized. It also stimulates metabolism and prevents free radical damage to cells. Moreover, B2 is important for eye health, skin and on and on ( 1 ).

In short, vitamin B2 is essential for the functioning of every cell in your body. And the lack or absence of this element in your diet can create a number of serious side effects.

Deficiency symptoms

Riboflavin is water soluble vitamin, and like all members of group B, he is supplied to us with food. Ideally, it should be replenished every day to avoid a shortage.

According to studies, vitamin B2 deficiency is not very common in Western countries. Most likely, because people consume a lot of refined carbohydrates, additionally fortified with riboflavin. In addition, other commonly consumed foods (eggs and meat) provide the body with this element to the fullest.

daily requirement for men is 1.5 mg/day and 1.3 mg/day for women. For children and infants, the vitamin is required much less.

Signs of deficiency of this element include ( 2 ):

• anemia
• fatigue;
• migraine;
• slow metabolism;
• malfunctions in the functioning of the thyroid gland;
• sores, cracks in the mouth and lips;
• skin inflammation and skin diseases;
• inflammation in the oral cavity;
• swelling of the mucous membranes;
• sore throat;
• mood changes - increased anxiety and signs of depression;
• hair loss;
• insomnia;
• pain in the eyes and rapid deterioration of vision;
• disruptions at work digestive system(from diarrhea to constipation);
• burning pains in the legs;
• sudden weight loss.

B2 deficiency is especially dangerous in childhood. This phenomenon negatively affects the growth and functioning of the central nervous system.

As for the excess of vitamin b2, cases of this are unknown. Excess quantity This element is excreted from the body after a few hours. Also, if you frequently consume multi-vitamins containing riboflavin, you may notice a bright yellow color in your urine. It `s naturally. Yellow in urine shows that your body is actually absorbing the vitamin. And you are not deficient. And your body properly gets rid of excess.

What products contain

Food sources of riboflavin are the following food groups ( 3 ):

• meat and offal;
• milk;
• cheeses;
• egg;
• green leafy vegetables;
• legumes;
• some nuts and seeds.

Riboflavin, along with other B vitamins, is also found in whole grain foods. Therefore, when you eat bread, cereal or bars from whole grain, you get that element. Although there isn't much of it.

And here are the top 10 food sources riboflavin (with an indicator daily rate 1.5 mg/day for adults). Meet these leaders.

This element is quite resistant to heat. Therefore, it is well preserved during the heat treatment of products - only 20% is lost during cooking.

But he also has an "Achilles heel": he quickly disintegrates under the influence of sunlight. Milk, cheese and other foods rich in B2 can lose 70% of the valuable vitamin molecules after 3 hours. Therefore, it is undesirable to store foods rich in riboflavin in translucent dishes.

In addition, part of the vitamin is lost when vegetables are washed in large amounts of water. Therefore, do not soak products for a long time. And when storing food in the refrigerator, they lose about 1% of vitamin B2 per day. Therefore, we eat fresh and do not store for a long time in the refrigerator.

Instructions for use and norms

For kids

For adults

If necessary, vitamin B2 can be bought at a pharmacy. It is sold in tablets, ampoules or as eye drops. The solution and the drug that is available in tablets is called riboflavin mononucleotide. The price for it depends on the form of release of the drug.

The body needs an additional intake of B2 in such cases:

• anemia;
• radiation sickness;
• disorders in the digestive tract;
• cataract;
• hepatitis;
• corneal ulcer;
• leukemia;
• pregnancy;
• lactation.

Also, workers in contact with salts of heavy metals and poisons need additional B2. And with increased emotional and mental stress, b2 increases the release of adrenaline into the blood. In this case, riboflavin is simply wasting its forces, which could be used for energy production. Therefore, stressed people should also consume additional vitamin supplements.

However, take pharmacy vitamin complexes and use drops only after consulting a doctor. He will write down the name of the drug that is recommended in each case. And tell you how much to take. Apart from pharmacy vitamins, riboflavin should be ingested with food. For example, you can eat liver or seaweed more often 🙂

Top 5 Vitamin B2 Benefits

1. Helps prevent migraines. Riboflavin is a proven method in the fight against excruciating headaches. A study found that taking 400 mg of the vitamin a day cut the number of migraine attacks in half. However, they did not compare the effects of riboflavin with conventional medications used to prevent migraine.( 4 ).
2. Supports eye health. Studies have shown that riboflavin deficiency increases the risk of certain vision problems. B2 helps prevent eye diseases including cataracts, keratoconus, glaucoma ( 5 ). Studies have shown a correlation between people who consume a lot of riboflavin with and a decrease in the risk of eye diseases. However, researchers don't know if this is due to riboflavin, niacin, or a combination of the two. In general, they will continue to study this vitamin. But for the treatment of glaucoma, riboflavin drops are prescribed along with the use of light therapy.
3. Helps prevent anemia. This disease is caused by several factors. These include decreased production of red blood cells, an inability to carry oxygen in the blood, and severe blood loss. Vitamin B2 helps to normalize all these functions, plus it is involved in the prevention and treatment of anemia ( 6 ). It is necessary for the synthesis steroid hormones and production of red blood cells.
4. Antioxidant properties. Riboflavin acts as an antioxidant that controls the presence of harmful free radicals in our body. It is needed for the production of an antioxidant called glutathione, which acts as a free radical killer. It also provides a detox for the liver. According to recent studies, B2 helps prevent certain types of cancer. These include colon, prostate, and cervical cancer ( 7 ).
5. Protects hair and skin. Riboflavin helps maintain proper levels of collagen, which keeps skin and hair healthy. We need collagen to keep our skin young and prevent wrinkles. So a deficiency in this vitamin can make you look older than your age. Some studies show that b2 also speeds up wound healing time.

Interaction with other drugs

Vitamin B2 has both "friends" and "enemies". Studies show that taking certain medications affects how quickly vitamin B2 is absorbed into the body. Keep this in mind if you are taking any of the following medicines:

• Anticholinergics - These drugs affect the stomach and intestines. They can increase the amount of riboflavin that is absorbed in the body.
• Medicines to treat depression (tricyclic antidepressants). It is possible that they can reduce the amount of riboflavin in the body.
• Phenobarbital - can increase the rate of decay of this element.
• Probenecid - may increase the rate at which B2 is absorbed by the body.

Vitamin b2 also interacts with drugs that are used to regulate the functioning of the thyroid gland. To such medicines belongs to thyrodin. It enhances the conversion of riboflavin to more easily digestible by the body forms are derived.

In addition, at simultaneous reception iron-containing preparations and vitamin b2, the absorption of the former is enhanced. Also, the B2 element contributes to the mobilization and preservation of iron in the body.

Vitamin B2 (riboflavin) is called the beauty vitamin for a reason, especially for women. If you want to have elastic, young, smooth, healthy skin, we must make sure that our diet contains foods rich in vitamin B2.

But not only beauty depends on the lack of vitamin B2 in the diet. Much more important is the state of vision and the brain, and hence the work of the entire nervous system, as well as the glands. internal secretion. Wounds on the skin or mucous membranes of the oral cavity are healed due to the growth of epithelial cells. This process can be accelerated by introducing vitamin B2 (riboflavin) into the diet. After the successful encouraging results of the use of vitamin B2 in animals for the treatment of cataracts, experiments on humans began. However, it turned out that riboflavin does not prevent cataracts, although it can delay its development. Other ingredients are also needed.

Lack of vitamin B2 in the body leads to poor eyesight, disorders of the nervous system, digestion, chronic colitis, gastritis, general weakness, various skin diseases, nervous breakdowns, depression, reduced resistance to disease. If your skin is not smooth and unhealthy, if you often have barley, herpes, boils, you should take foods rich in riboflavin and urgently change your diet by introducing foods rich in this vitamin into it.

Like vitamin B1, riboflavin helps to burn sugar, improves the functioning of energy mechanisms. In combination with proteins and phosphoric acid in the presence of trace elements such as magnesium, it creates the enzymes necessary for the metabolism of saccharides or for the transport of oxygen, and therefore for the respiration of every cell in our body. If you have wrinkles that radiate from the lips, especially above upper lip if there are cracks in the corners of the mouth, chapped lips, burning eyes, peeling skin on the nose, ears or forehead, if you have a purple tongue, greasy hair, reddened eyelids - all these can be symptoms of a lack of riboflavin. Similar phenomena occur with iron deficiency.

Riboflavin prolongs the life of red blood cells and together with folic acid(vitamin B9) is involved in the process of creating new blood cells in bone marrow. In addition, vitamin B2 helps absorb iron and, together with vitamin B1, helps maintain the level of this trace element in the blood. That is why anemia patients are advised to take iron supplements along with vitamin B2 and folic acid. This is especially true for pregnant women: doctors note that it is they who often have a lack of these substances. In this case, taking foods rich in vitamin B2, along with iron, can be a salvation for the mother and for the child. Doctors noticed that women who had enough vitamin B2 in their bodies produced healthy, well-developing offspring. Of course, because the mother's body contains enough B vitamins and especially vitamin B2, the child will not become Einstein, doctors say, but for proper development brain, these vitamins are absolutely essential.

How much vitamin B2 does a person need?

AT guidelines 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 12/18/2008 provides the following data:

Physiological need for Vitamin B2, mg per day:

Upper allowable level Vitamin B2 consumption has not been established

How to meet the body's daily need for vitamin B2?

If sour milk and 50-100 g of cottage cheese or cheese are included in the diet, then it is practically possible to satisfy the daily requirement for vitamin B2. But at least 3 glasses of curdled milk or kefir are required per day, especially during severe physical work or sports when the need for this substance increases. Except sour milk, cottage cheese and cheeses, a large amount of riboflavin contains leafy green vegetables, unrefined grains or bread from it, liver, kidneys and meat. By the way, the softer the cottage cheese, the more whey is left in it, which means that it contains more vitamin B2. Milk in a glass container in daylight, for example, by a window, loses 50% of riboflavin in 2 hours.

What factors reduce the level of vitamin B2 in our body?

First of all, medicines, as well as insufficient or increased function thyroid and other diseases. Riboflavin is destroyed by drugs used in psychiatry, oral contraceptives, boric acid, which is included in more than 400 household products (for example, in washing powders),

Riboflavin is well tolerated high temperature, but does not like light and is soluble in water. If food is cooked in an open dish, and the water is drained, its losses will be great. Vitamin B2 is destroyed by defrosting vegetables and beef meat for 14-15 hours in the light, but is stored in the refrigerator. Vitamin loss can be avoided by placing frozen foods immediately in boiling water or defrosting in the oven by wrapping them in aluminum foil. Always cover the utensils in which food is cooked. Otherwise, many vitamins are oxidized. Keep in mind that part of vitamin B2 is lost when vegetables are washed in large amounts of water, and part is lost during storage, even in the refrigerator (about 1% per day). This suggests that you do not need to soak vegetables for a long time and buy them in large quantities.

Foods rich in vitamin B2, riboflavin

Translated from Latin the word "vitamin" is translated as "life" and "protein". And letters were assigned to vitamins as they were discovered. The names of some of them have not only a letter designation, but also a verbal one. For example, B2 - riboflavin, vitamin A - retinol, B12 - cyanocobalamin. Despite the fact that we need these elements in small doses, their consumption should be daily. In some cases, the need for them increases: for example, during pregnancy, with certain diseases, with increased physical or mental stress.

Ways of getting vitamins into the body

• Exogenous. In this case, vitamins enter our body from the outside - with food or with dietary supplements. Most the best option, of course, will natural products. First, they are better absorbed by humans. Secondly, nature provides a combination different groups vitamins that enhance each other's effects.
• Endogenous, or internal. Vitamins come from the synthesis of bacteria in the intestine. Weak sides This way - a small amount of production, possible failures due to diseases of the digestive tract, as well as insufficient absorption of vitamins from the colon as a result of taking antibiotics.

Causes of insufficient intake of vitamins from food

• Unsatisfactory product quality. After all, the habitat and ecology have changed, and as a result, agricultural crops do not receive in full all the necessary nutrients. Pollutants further deplete already modest reserves. The human diet is becoming increasingly scarce. As a result, it is not always possible to compose your menu in such a way as to fully provide the body with the substances it needs.
• Vitamins disappear during the heat treatment of products.
• Disturbed digestive functions do not allow the body to absorb the necessary substances.
• Inadequate or unbalanced intake of vitamins.
• Seasonality factor: by autumn, the body accumulates vitamins, and by spring, their deficiency is detected. Vitamin intake should be regular. Please note that before you start taking multivitamins, you should consult a specialist.

Riboflavin: description

B2 vitamin, or growth vitamin, is essential human body for normal functioning cells, metabolism of proteins, fats, carbohydrates, tissue respiration. Riboflavin is a water soluble substance. In combination with vitamin A, it helps to ensure the integrity of the mucous membranes. In addition, this element is involved in the absorption of vitamin B6 and iron from food, helps relieve eye fatigue, and prevents cataracts. Preparations containing vitamin B2 are used in the treatment of skin diseases, poorly healing wounds, anemia, diabetes, eye diseases, intestinal pathologies, and cirrhosis of the liver.

The main functions of vitamin B2

• Participation in the absorption of iron by the body;
• Participation in all metabolic processes, including ATP synthesis;
• Synthesis of hemoglobin;
• Maintaining the normal functioning of the organs of vision;
• Ensuring the normal functioning of the thyroid gland;
• Maintaining in healthy condition skin, nails, hair.

What is riboflavin

Vitamin B2 is found in foods such as milk, cereals, greens, liver, kidneys, vegetables, yeast, almonds, mushrooms. It does not accumulate in the human body, so its daily reserves should be replenished. The average daily requirement for this vitamin averages 1.3 mg. In pregnant women this norm increases to 1.6 mg. It must be remembered that light destroys vitamin B2 in food. This must be taken into account when preparing food and storing food. It is undesirable to boil pasteurized milk, as heat treatment can completely destroy the riboflavin contained in milk.

Why is there a lack of riboflavin in the body?

The main causes of vitamin B2 deficiency in the body are as follows: an unbalanced diet, a lack of this vitamin in the incoming food, improper storage or preparation of foods rich in riboflavin. Another reason may be malabsorption in the intestines, an increase in the need for this vitamin with an increase physical activity or, for example, pregnancy. chronic diarrhea, liver disease, alcoholism can also cause vitamin B2 deficiency.

Symptoms of B2 deficiency

A manifestation of riboflavin deficiency can be seborrheic dermatitis (rough scaly skin, especially on the face), angular stomatitis, which is characterized by cracks in the corners of the mouth. Possible nervous disorders, weakness in the muscles, pain in the legs. Generally, vitamin B2 deficiency without complications is rare. More often it is combined with malnutrition and changes in biochemical parameters. Deficiency of this vitamin adversely affects children's body. So, children with a deficiency of riboflavin lag behind their peers in development, their memory deteriorates and inattention and absent-mindedness appear. If vitamin B2 deficiency is suspected, a blood test is ordered.

Vitamins in ampoules

To compensate for the lack of riboflavin, the course of admission is often 1 - 1.5 months. B2 combines well with vitamin B6, enhancing its effectiveness. It will also be useful to combine riboflavin with zinc preparations. This combination will improve the absorption of zinc, making it more bioavailable. Riboflavin is incompatible with vitamins C and B1.

Necessity for pregnant women

Vitamins B1, B2 are required by pregnant women in significantly more than ordinary people. The daily requirement for thiamine in women in an "interesting" position is 10-20 mg per day. Thanks to the intake of vitamins, it is prevented early manifestation toxicity, weakness labor activity, stimulates the work of the cardiovascular and nervous systems, improves appetite. With a deficiency of these elements, digestive disorders occur, weakness in the muscles, pain in the heart area appear, and there is a violation of the development and growth of the fetus. Vitamin B2 also prevents cracked nipples.

B vitamins

The whole complex of B vitamins provide healthy work nervous system and is responsible for energy metabolism. Also, these elements largely depend on the functioning immune system and efficiency of cell growth. Modern man experiencing mental and emotional stress subject to stress, chronic diseases B vitamins are needed in significant amounts. Vitamins B1, B2, B6 are found in brewer's yeast. Pyridoxine is necessary for the body to assimilate amino acids, takes part in fats, carbohydrates. B12 can be obtained through consumption beef liver. Cyanocobalamin is needed for normal hematopoiesis, provides normalization fat metabolism in the liver, helps lower blood cholesterol levels and improve memory.

Vitamins B1, B2, B12 are the basis for the normal functioning of any organism among mammals. As a rule, with a deficiency of these substances, they first appear minor symptoms that people usually don't pay attention to. However, later they lead to irreversible changes. Thus, the content of calcium, phosphorus, zinc and magnesium decreases in the body. This, in turn, is expressed by tooth decay, physical exhaustion, decreased appetite, and as a result, anorexia, visual impairment.

Vitamins B6, B2, B1, B12 are water soluble, so they need to be consumed daily with food. You can also buy riboflavin in ampoules at a pharmacy. But this should only be done if there is a vitamin deficiency. long time and only after consultation with your doctor. Complex action B vitamins are much more effective than each element separately. Unbalanced diet leads most often to a lack of a number of vitamins, so they must also be taken in combination.

Important about vitamins

These substances are destroyed during heat treatment. Vitamin B2 is light sensitive and water soluble. It is impossible to get an excess of these trace elements from food. The excess is excreted by the body with excretion products. B vitamins must enter our body daily, as they do not have the ability to accumulate. These substances are destroyed by alcohol, caffeine, nicotine, tannins, refined sugar. They can also be excreted from the body when antibiotics are consumed. To avoid such risks, during the course of a particular treatment, the doctor may prescribe vitamin B2 in ampoules. Increases speed during times of stress metabolic processes Therefore, in such cases, the body's need for vitamins increases. For gastritis and peptic ulcer there is a violation of the synthesis of vitamin B by the microflora of the body.

food and vitamins

Vitamin B2 is rich in food of animal origin: milk and dairy products, yogurt, ice cream, poultry meat, eggs, fish, cheese, liver, yeast. Nuts, cereals, mushrooms, green vegetables - broccoli, spinach, avocados can also enrich the body with this trace element. For getting daily allowance riboflavin will be enough half a teaspoon of unpeeled uncooked pine nuts. If included in daily diet buckwheat, rice and oatmeal, then you can not worry about the lack of vitamin B2 in the body. Fruit lovers should know that the most riboflavin is found in apricots.
