Vitamin B7 (Biotin): important properties, benefits and harms to the body.

Vitamins are necessary to maintain health and normal processes in the body. However, you also need to know which ones a person needs at a particular period of life and why. Therefore, it is desirable to study the effect of certain vitamins on the body. This article is devoted to a substance that is found in food, dietary supplements and hair cosmetics. These are biotin vitamins. Reviews about them on the Internet are found at every step. Let's try to understand their real influence on the body and the effect of use.

Properties

Vitamin H is actually B7, aka biotin. Reviews about this drug, as well as general information about it, are usually found under the name biotin. This is a white substance, a crystal that is destroyed under high temperature and in an alkaline environment. It is involved in the formation of fatty acids and individual biologically active substances.

It is produced in the body, but, according to some estimates, it is not enough to satisfy the entire need for such an element as vitamin H (biotin). Reviews about its use are often positive, so one involuntarily wants to try this product. But are additional preparations containing this vitamin really necessary? To answer this question, it is necessary to study the vitamin: its composition, functions, where it is found, how it is produced, and so on. So, let's begin.

Functions

participation in the production of glucokinase, which stimulates glucose metabolism;
regulation of blood sugar through interaction with insulin;
participation in carbohydrate metabolism;
promoting protein absorption and fat burning;
the sulfur contained in the vitamin has a comprehensive positive effect on hair, nails and skin, because it participates in the formation of collagen, which is the basis for bones, skin, nails and hair;
helps the normal functioning of the nervous system, since the latter feeds on glucose, which in a certain sense is catalyzed by biotin;
participates in the synthesis of intestinal microflora.

Symptoms of deficiency or excess in the body

With a lack of this vitamin, blood sugar and cholesterol levels decrease, weakness and drowsiness, muscle pain, lack of appetite, nausea and depression are observed. With an acute deficiency, hair loss, dandruff are added to these symptoms, the skin becomes excessively oily or, conversely, dry.

The vitamin is extremely important for maintaining stable blood sugar levels. Nerve and brain cells feed only on glucose. Therefore, it must be constantly sufficient. Per one hundred milliliters of blood, glucose is contained at a normal balance of eighty to one hundred milligrams. If its content is reduced to sixty milligrams, then the person becomes nervous, tired and irritable. And when there is only thirty milligrams of glucose in the blood, then he is completely unable to solve everyday problems. Any negative response can lead him to a nervous breakdown.

On the other hand, when an excess of a vitamin such as biotin was recorded, the reviews were never negative, that is, no side effects have yet been observed.

Because biotin comes from food and is also produced in the body, some experts believe that supplemental supplementation is not necessary.

What products contain

The vitamin is found in many foods that can be consumed daily:

eggs;
kidneys;
liver;
yeast;
milk and products made from it;
cabbage, beets, spinach;
nuts;
legumes;
fruits;
champignons and porcini mushrooms;
leaves of wild strawberries and blueberries.

It is also found, although in a smaller percentage, in bananas, walnuts, potatoes, bran, mackerel, and salmon. In spring, its source is lettuce leaves, which are good to add to vitamin-rich dishes. In winter, you should constantly eat oatmeal, which, in addition to containing biotin, promotes the proliferation of friendly intestinal microflora with it.

If fruits and vegetables are present in the daily diet, and a person moves a lot, then he does not need to worry or think about this vitamin. Those people for whom everything is different and, moreover, their hair and nails look painful, should first eat the above foods every day. You need to consume fifty micrograms of the substance per day. There is no need to worry too much about the fact that your body will contain too many vitamins from natural products, in particular biotin. No negative reviews were found anywhere on this matter.

How is it sold?

Vitamins can be purchased in the form of a drug called “Biotin complex” - a dietary supplement with half a gram tablets. It is also contained in such medicines as Volvit, Medobiotin and Deacroix. In addition, it is part of other additives, such as: “Discovery-strength”, “Discovery-excellent”, “Discovery-charm”, “Hepaton”, “Neurostabil”, “Laminarin”, “Glyukosil”, “Woman’s Formula” ".

Indications

It is advisable to use biotin additionally in the following cases:

when, due to poor nutrition, consumption of alcoholic beverages, dysbacteriosis, or long-term use of antibiotics and cold medications, it is not sufficiently produced;
to maintain blood sugar levels;
if the function of the sebaceous glands on the head is impaired, which causes dandruff and hair begins to break and fall out;
as an additional remedy for general muscle weakness, depression, drowsiness, loss of appetite.

Contraindications

If individual intolerance to biotin components is detected, its use should be discontinued. It is also not recommended for use during pregnancy and lactation.

How to use

For prevention, the drug is taken daily, two tablets with meals. If the goals are therapeutic and prophylactic, then its dose should be doubled. Before you start using the complex, you should consult your physician on this issue.

Side effect

No side effects have yet been identified in connection with the intake of a dietary supplement containing biotin. Reviews and the price of the drug are discussed in the last paragraph of the article.

Interaction with other drugs

If the complex is taken together with medications against seizures, the level of the active component in the blood will decrease, since elimination from the body will be significantly accelerated.

Volproic acid will reduce the activity of enzymes that impair the absorption of the vitamin.

Zinc will enhance the effect on the growth of skin appendages.

Pantothenic acid and Vitamin B5 can reduce the effectiveness of biotin. Therefore, they should be taken at different times.

The same applies to egg whites. Avidin, which is part of it, enters into a strong relationship with the vitamin, which ultimately disrupts absorption, and the level of effectiveness of the latter is significantly reduced.

Sale

Vitamins are freely available and available without a doctor's prescription.

Biotin: reviews

The popularity of the vitamin complex remains consistently high. Many people use biotin for hair as a remedy against hair loss and promotes hair growth. The reviews from women after taking this drug are truly impressive. Even when used independently (without the use of other means), hair loss is noticeably reduced, and together with other methods it stops completely.

Thus, you can find on sale in some lines of cosmetic products, for example Kapous Professional, masks, lotions, serums and Biotin shampoo. Reviews for the most part speak of its positive effect on curls. At the same time, you need to be careful about the brand of shampoo and choose one that has earned the trust of customers.

However, although such a series of products as “Kapus” with biotin is known, there are not so rosy reviews about it. Let us emphasize once again: consumers must choose for themselves which brand of shampoo to buy. It is advisable to pay attention to the full composition of the substances included in the product. Indeed, in addition to the advertising, attention-grabbing text, there is also the reverse side of the packaging, and it may contain information about the content of elements that are not at all beneficial for hair. Therefore, you should never neglect the so-called natural ingredients containing the same biotin. For hair growth (reviews are usually not written about natural food products that contain it) it will be much more useful. The state of health naturally gradually (and sometimes unnoticed by the person himself) improves, and with it the hair becomes healthier.

Before you start taking dietary supplements with biotin, you need to know for sure that your body really lacks this component. After all, the body is capable of producing biotin itself. If there are reasons (indications for taking a vitamin) and an improved diet has not changed the situation, then, with the consent of the doctor, you can start taking vitamins. But remember that health is always in your hands and you should not give it into the hands of advertisers who make money. You should always be careful about what you consume. When making a decision, you can and should ask your body whether it really needs this remedy?

If the answer is yes, then all that remains is to buy the drug. Biotin complex from various manufacturers costs in the range from 700 rubles to 3000. Hair cosmetics, for example “Kapus” with biotin, can be purchased at a cost of 400 rubles. Disposable ampoules are sold at prices starting from 150 rubles.

Many representatives of the fair sex dream of luxurious long hair, and if nature has not rewarded you with good hair, using hair vitamins with biotin will help correct the situation.

Biotin or vitamin B7 can rightfully be called the beauty vitamin.

It is actively involved in the breakdown of fats and carbohydrates, maintains blood sugar levels, enhances the activity of hair follicles and regulates the functioning of the sebaceous glands.

Thanks to biotin, the skin maintains a healthy, vibrant appearance, and the hair remains strong and shiny.

Vitamin B7 is produced in sufficient quantities in a healthy body, but poor nutrition can disrupt this process.

In this case, it is necessary to increase the consumption of foods high in biotin or take pharmacy vitamins that contain it.

Vitamin B7 deficiency can be caused by the following factors:

violation of metabolic processes;
strict diets, unhealthy diet;
taking certain antibiotics;
pregnancy and breastfeeding.

A lack of biotin leads to decreased muscle tone, low blood pressure, skin changes, hair loss, thinning and brittle nails.

Also, the lack of this vitamin negatively affects the state of the nervous system.

Some substances interfere with the absorption of biotin, most notably preservatives that are often added to store-bought products.

Raw egg whites and alcohol also interfere with the body's ability to absorb vitamin B7.

Large amounts of biotin are found in bran, legumes, nuts and cauliflower.

However, the record holder for the content of this substance is pork liver; it contains 4 times more vitamin B7 than beans.

Fermented milk products rich in biotin also improve intestinal microflora, which promotes the production of this substance in the body.

However, to get the maximum amount of vitamin B7 from foods, you need to follow some rules.

Firstly, biotin is poorly preserved in food during preservation. If you want to preserve berries for the winter, it is better to freeze them in the freezer rather than prepare compotes and jam.

For salads, cook vegetables in their skins, so they retain not only biotin, but also other vitamins.

The main enemy of biotin is frying: foods prepared in this way will not bring any benefit to your body.

Biotin for hair

Vitamin B7 can help with almost any hair and scalp health problem.

It is not only a powerful growth activator, but also protects curls from increased dryness and brittleness, prevents the early appearance of gray hair and hair loss.

Biotin is also excellent at fighting dandruff and scalp flaking.

Many shampoos, balms and masks containing this substance are now sold in stores and pharmacies. Shampoos with biotin are recommended for severely damaged and dry hair.

The vitamin in the shampoo helps to restore the structure of the hair and protects the scalp from overdrying.

In addition, these shampoos are an excellent tool for the prevention of dandruff. The most popular shampoos with biotin come under the brands Horsepower, Avalon Organics and Kapus.

Almost all of them contain other beneficial substances for hair growth, including keratin, collagen, plant extracts and natural oils. But, as a rule, there are no parabens and sulfates in such products.

If your hair is severely damaged as a result of dyeing or frequent use of straightening and curling irons, using hair masks with biotin will help restore your hair to a healthy and well-groomed appearance as quickly as possible.

A mask with vitamin B7 from the company Kapus receives excellent reviews. This product promotes hair regeneration and prevents hair loss.

The mask is interesting in that it can be left on after application, in which case it acts as a nourishing cream, and the effect of biotin is enhanced.

Leave-in serums and lotions with biotin perfectly moisturize curls throughout the day, as well as nourish hair roots and stimulate blood circulation in the scalp.

They are easy to use, after using them the hair is easy to comb, acquires a healthy shine and volume.

In some online stores you can order vitamin B7 in the form of a solution. Liquid biotin is added to homemade nourishing masks.

Mask with avocado and biotin. Mash the avocado pulp with a fork or grind in a blender. Add two tablespoons of burdock oil to the resulting puree and stir the mixture until completely homogeneous.

Pour in a tablespoon of liquid biotin and a few drops of your favorite essential oil. This mask is distributed over the entire length of the hair and washed off without using shampoo.

Multivitamins with Biotin

The use of hair vitamins with biotin is necessary if the body does not produce this substance in the required quantity.

In pharmacies you can find biotin in its pure form, usually in the form of tablets and capsules. This element is included in most multivitamins to maintain the beauty of hair and nails.

The drug "Volvit" is biotin in its pure form with excipients. To improve hair condition, this dietary supplement should be taken twice a day with meals.

It has no contraindications or side effects.

The “Complivit Radiance” vitamin complex, in addition to biotin, also contains other B vitamins, as well as vitamins A and E.

The drug promotes collagen production, removes toxins from the body and has an antioxidant effect.

German drugs from the Doppelgerz company receive extremely positive reviews. Thanks to the high quality and well-chosen composition, Doppelgerz Vitamins for healthy hair and nails have long conquered the Russian market.

This biological supplement contains the required dose of biotin, as well as calcium and zinc - minerals that promote active hair growth.

This drug will improve the condition of hair and nails, and also protect them from the negative effects of the environment.

The Perfectil complex includes almost all the vitamins, minerals and acids necessary to strengthen hair.

Thanks to the excipients, all microelements are easily absorbed by the body.

Taking Perfectil improves blood circulation, which contributes to the active work of hair follicles and accelerated hair growth.

The effectiveness of Alphabet Cosmetic multivitamins for maintaining healthy hair and scalp is confirmed by numerous customer reviews.

This Russian-made drug is fundamentally different from other vitamin complexes for women.

It is designed in such a way as to satisfy about 80% of the needs of the female body in vitamins and trace elements.

During the day, you need to take three tablets with different composition, so that substances that cannot be taken at the same time enter the body without weakening each other's actions.

Before taking any pharmacy drug, it is advisable to consult a doctor and carefully read the instructions. Study the composition and list of contraindications so as not to harm your body.

Only properly selected vitamins and nutritional supplements will help maintain the beauty and health of your hair.

Vitamin B7 (Vitamin H, Medobiotin, Biotin, Coenzyme R)

Vitamin B7 was first described in 1901 by the scientist Wildiers as a substance necessary for the development of yeast cultures. In a free crystalline state, the compound was obtained by F. Kegle only in 1935 from egg yolks. The substance was given the name “biotin” - “essential for life.”

Coenzyme R (another name for biotin) is involved in many processes of skin and nerve metabolism. By nature it is a powerful catalytic substance.

Physico-chemical parameters of the compound

In the free state, vitamin H is a crystalline compound, highly soluble in aqueous media. It is a very active substance.

Foods High in Vitamin B7

Foods high in biotin include:

egg yolks,
yeast,
tomatoes,
nuts,
mushrooms,
cereals,
carrot,
potato,
cottage cheese,
sour cream,
cream,
strawberries,
kidneys and liver.

How to preserve vitamin B7 in foods as much as possible

Vitamin B7 is susceptible to destruction under adverse conditions. So, to preserve more vitamin B7, it is better to freeze foods rather than canning them.

Prolonged soaking of products in aqueous solutions adversely affects the content of vitamin B7. It is recommended to store products not in sliced, but in a whole state, and it is better not to allow them to be stored for a long time, even in the refrigerator.

Frying significantly reduces the amount of substance in the product - it is better to replace this type of processing by boiling it in the peel under a lid. Roasting does not significantly affect the amount of biotin remaining.

Products with a high content of biotin

With insufficient use of biotin with food, its content in the body can be increased by taking medications with increased dosages of the substance. There are many mineral complexes that can provide the daily requirement of the vitamin.

In finished form, the substance is produced singly - under the trade name "Biotin". The drug has several forms of release - capsules, tablets and solutions for injection. In the case of the first two forms, the medicine is taken once a day before meals. Typically, the therapeutic dose is set at 5 mg per day. In case of more serious abnormalities (such as enzymatic deficiency or malabsorption), the dosage, on the recommendation of a doctor, can be increased up to 20 units. The course of additional vitamin intake usually does not exceed a month.

Typically, injections are given to people with intestinal problems. The ampoule form of the substance is administered intramuscularly once a day. One ampoule is enough. If external use of the vitamin is intended, especially in the treatment of hair deviations, a solute is rubbed into the steamed skin and massaged for about 3-4 minutes. The optimal dosage is 2 ml.

The ampoule substance also effectively fights inflammation and skin rashes. With prolonged use it has a lifting effect.

Analogs this drug can serve Honeybiotin And NeoVital Biotin 0.1%.

Taking the substance has a number of indications. These include:

avitaminosis coenzyme R;
deviations in the gastrointestinal tract;
diabetes;
diets;
taking antibiotics;
dryness and slow hair growth;
nervous abnormalities;
maladsorption syndrome;
dermatitis.

There are no significant contraindications to taking vitamin H. With caution, it should be taken during pregnancy and in case of hypersensitivity of the body to the substance.

Vitamin H can be found in some hair shampoos. Also, a number of vitamin complexes contain the substance as one of the components.

Required daily dosages of coenzyme R

The average daily intake of biotin for adults ranges from 25-30 mcg to 110 mcg. The need for a vitamin may vary depending on the individual's physical condition and actual age.

Status	Average daily dosage (mcg)
Infants up to six months	4,8
Infants up to one year old	6,1
Children under 3 years old	8,2
Children under 9 years old	11,7
Teenagers under 14 years old	21,5
Young people under 18 years of age	25,3
Adults	29,8
Pregnant women (dosage also suitable for breastfeeding women)	51,6

Functions of vitamin H, beneficial properties

Increased biotin intake is indicated for people with diabetes mellitus of any stage, mycoses, epileptics, infants, pregnant women and those who, as a result of taking antibiotics, disrupt the normal functioning of the body's flora.

Biotin takes part in almost all metabolic processes of the body, stabilizing and normalizing them. Thus, lipid, protein and carbohydrate metabolism improves.

Vitamin B7 is indispensable for the synthesis of fatty acids in the body, ensures the proper growth of new cell systems, improves the condition of hair and skin. Nervous activity is normalized: bone marrow tissues and nerve fibers are healed. Adequate intake of biotin can reduce muscle pain.

Vitamin H is also useful for the enzymatic function of the body: it is involved in nine enzymatic processes. The substance maintains a normal environment in the intestinal cavity.

The functions of vitamin B7 also include:

participation in the functioning of the thyroid gland;
interacts with insulin, normalizing blood sugar levels;
activation of ascorbic acid;
control of gluconeogenesis;
stimulation of red blood cell synthesis;
participation in the formation of DNA molecules;
ensuring hemoglobin synthesis.

Vitamin B7 is also good for hair. The substance is used as a strengthening agent for hair follicles. The coenzyme has a positive effect on the hair, moisturizing it and preventing the development of early gray hair. Vitamin H also affects the secretion of the sebaceous glands of the skin - if they are hyperactive, it suppresses their activity, if they are inactive, it stimulates the production of sebum. The compound helps in the fight against dandruff, dermatitis and eczema of the epidermis.

Coenzyme R can be taken orally or added to preparations, shampoos and ointments for external use.

The harmful effects of vitamin B7

Due to the complete aqueous solubility of the substance, its use does not have any obvious negative consequences. People suffering from individual intolerance to the substance and allergies should take the substance with caution. Manifestations of hypersensitivity may include small rashes and hives.

Vitamin B7 absorption

Coenzyme R is highly absorbable from food. In addition, some studies have shown that some of the compound is formed in the human intestine.

There are substances that affect the absorption of a substance. Thus, raw egg whites contain a special substance, avidin, which is an antagonist to biotin, blocking the absorption of the latter into the circulatory system. Heat-treated protein due to denaturation does not interfere with the absorption of vitamin B7 - avidin in the processed protein is destroyed.

Eating heated or oxidized fats can slow down the absorption of the vitamin. Sulfur-containing drugs and saccharin have a similar effect.

The constant abuse of alcoholic products can also adversely affect the content of the compound in the body.

Insufficient vitamin H content

A lack of biotin in the body results in a number of symptoms. These include:

decreased blood pressure;
mental disorders;
decreased muscle and vascular tone;
disruption of metabolic processes;
growth slowdown;
manifestation of anemia;
pallor of the tongue;
skin rashes;
slower hair growth, deterioration in quality;
irritability;
drowsiness;
muscle pain, weakness;
increase in the concentration of sugar in the blood;
nausea, lack of appetite.

Biotin hypervitaminosis

The occurrence of excess vitamin B7 in the body is possible, although this phenomenon is rare, since the vitamin dissolves and is excreted in biological fluids. When ingested in dosages several times higher than recommended, the following symptoms may appear:

significant improvement in the quality of hair and nails;
increased frequency of urination;
excessive sweating.

Interaction between biotin and other compounds

With an average dosage of substances, biotin interacts well with the mineral magnesium and other vitamins of the group, especially B9 and B12.

Vitamin B7 is negatively affected by taking antibiotics, long-term use of sweeteners (saccharin) and sulfur-containing medications. This happens due to the deterioration of intestinal function and, as a result, a decrease in the digestibility and synthesis of coenzyme R.

Preservatives destroy most of the incoming vitamin B7 (especially substances of the E221-E228 type).

The bioavailability of biotin is reduced when taken simultaneously with substances containing valproic acid, but when vitamin H is taken together with anticonvulsants, the effectiveness of the latter is reduced.

Vitamin B7 has a significant impact on the metabolic processes of the human body. Without its sufficient consumption, the skin and mental processes of the body are disrupted, anemia and weakness may develop. Pregnant and lactating women should be especially careful to ensure sufficient intake of vitamin H.

Not every beauty can boast of healthy and attractive hair. In addition to improper care, the condition of curls is affected by stress, poor environment, unbalanced diet, and bad habits. By using professional cosmetics or home remedies, you are only masking the problem. And the strands need better help. Biotin for hair is able to restore hair at the cellular level.

Biotin has other names - vitamin B7, H, plus it is deservedly called the “beauty vitamin”. What is its role? It converts carbohydrates, fats and amino acids entering the body into glucose (energy). Without it, the body's systems simply cannot function properly.

Vitamin deficiency occurs rarely. We consume it with food and it is produced by the intestinal microflora in the required quantity. The daily norm for an adult is 30-50 mg. Its deficiency can be caused by indigestion and a long course of antibiotics. Alcohol and preservatives that enter the body when eating food destroy biotin.

Properties B7

Biotin can increase body tone and stabilize blood sugar levels. It helps to absorb beneficial substances, on which the health of the hair depends. By normalizing the fat-protein balance, participating in carbohydrate metabolism, accelerating collagen synthesis, the vitamin provides beauty to the hair.

How it works

A deficiency of nutrients in the body affects the condition of the curls. They become dry and fall out, lose vitality, split ends. Vitamin B7 plays an important role in maintaining beauty. Its benefits are as follows:

is a means for the prevention of diseases such as seborrhea, psoriasis, dandruff;
regulates the functioning of the sebaceous glands;
activates the work of “dormant” hair follicles;
helps to produce elastin and collagen;
helps strengthen hair;
stimulates their growth;
prevents hair loss.

Often, vitamin H is prescribed by doctors to treat pigmentation. It is used in the prevention of premature aging of strands. It is able to make curls shiny, thick, and provide them with an attractive appearance.

When to use

Vitamin B7 interacts well with other elements of this group, including B5, B9, B12. Therefore, it can often be found in complexes. Indications for use:

inflammation and dryness of the skin of the head;
increased fat content and dandruff;
brittleness, dullness of strands;
gray hair

Biotin is used for hair loss. It supplies the body with proteins and amino acids, which take part in all construction processes of the body. The vitamin is prescribed if the curls have lost their elasticity or suffer from exposure to aggressive external factors. It is involved in the production of keratin, which, in turn, can eliminate problems.

Contraindicated for whom

The appearance of side effects from taking vitamin B7 is a rarity. In most cases, they occur only with individual intolerance to the element. It could be a skin rash, hives. Even with a large dosage, it is impossible to poison them. At least, there are no marks about this, confirmed by research.

The drug is not prescribed during lactation. When breastfeeding, a young mother and baby require a completely different set of vitamins than an ordinary person. It is selected only by a doctor. The vitamin is also contraindicated during pregnancy. Although it is not toxic, expectant mothers should be wary of its use. Too much can lead to allergies.

Biotin for hair: nourish curls from the inside and out

In the fight for healthy hair, we adhere to the following principle - the more ways, the better. Vitamin H biotin for hair can enter the body both from the inside and from the outside. In the first case, it is used with food or in its pure form, in the second, it is added to homemade masks and is present in professional cosmetics.

Products

The largest amount of the element is found in products of animal origin. These are beef, pork liver and kidneys, bovine heart, egg yolks. It is also present in veal, chicken, ham. For women who care about the health of their curls, it is useful to consume the following products:

milk and cheeses;
herring, flounder, canned sardines;
vegetables, fruits, berries;
mushrooms;
whole grains and bran from rice, rye;
peanuts and almonds.

In animal products, the vitamin comes in conjunction with protein. In vegetables and fruits, it is present in a free form. In the body, biotin is synthesized by the intestinal microflora. During heat treatment, products lose a certain amount of it. Therefore, it is more useful to steam, use them fresh.

Homemade shampoo and masks

It is not necessary to buy masks, balms and other products with biotin in the store. You can prepare effective mixtures yourself at home. For example, you can make shampoos with biotin for hair based on live beer, preferably dark varieties. This drink itself is rich in vitamins, including B7. We proceed in five steps.

Mix a glass of dark beer with two tablespoons of sunflower or olive oil.
Add the contents of the biotin ampoule.
Apply the mixture to the roots and gently massage.
Let stand for 15 minutes.
Wash off with warm water.

Fans of folk cosmetology can also prepare masks. We enrich natural formulations with biotin. We look at the recipes in the table.

Table - Recipes for homemade hair masks with vitamin B7

Useful will be recipes where jojoba oil, egg yolk, banana are present. You can just wash your hair with a raw egg.

Other Applications

At home, we use vitamin H not only in our own masks. It can also be added to regular store products. Before use, dilute the liquid element or powder, according to the instructions. We carefully read the recommendations and make sure that the vitamin can be combined with certain components of professional cosmetics. In addition to those proposed, there are at least three more options for using the vitamin.

Massage . Apply a small amount of liquid biotin to your fingers. Massage the head for 30 minutes. After that, we can immediately wash off the product or leave it for 20 minutes, warming the head with a shower cap, a towel.
End care. Vitamin B7 for hair in ampoules helps in the fight against split ends. After each shampooing, apply a small amount of product to wet or dried strands. We don't rinse.
Spraying. Pour filtered water into the spray bottle and add one ampoule of the product to it. We can use biotin for hair in tablets. Grind them first to make a powder. Shake the mixture well until it is completely dissolved. Periodically irrigate the hair at least once or twice a month. We increase the number of procedures in winter and spring, with alopecia, when the strands especially need additional nourishment.

As with other drugs, the “beauty vitamin” will be ineffective and useless if used incorrectly. Having studied the reviews about biotin for hair left by beauties on the forums, we highlight six relevant tips.

Feeding from within. We make masks, eat certain foods - these are not all the existing measures. You can take biotin for hair growth as part of pharmaceutical preparations. We buy a vitamin separately or in a complex. We do this only in consultation with the doctor. He will prescribe the dosage, treatment regimen. It will help you select other vitamins and microelements necessary for the body.
We visit the salon. Choose . During the procedure, the cosmetologist makes injections into the scalp. The method helps strengthen the hair and stimulates the growth of strands. For mesotherapy, not only vitamins are taken, but also amino acids. The composition of the injections is selected individually.
We warm. The product is much more effective if heated. Increasing the temperature allows it to penetrate the hair faster. Therefore, when using it, we always try to insulate the head with a polyethylene cap or towel. If you don’t have a hat, then a regular plastic bag will do, but without inscriptions or pictures.
We're not in a hurry. Be sure to keep the masks for as long as prescribed in the instructions. The same applies to funds in ampoules.
We keep it right. Regardless of what container the vitamin is in, keep it in a cool place. The product must not be exposed to direct sunlight. We use ready-made mixtures immediately and do not store them.
Consider contraindications. Although in most cases the drug does not cause harm, its use is best controlled. We visit and consult a doctor.

Remember that a one-time use of the product will not bring the desired results. As soon as the first signs of a deterioration in the condition of the hair appear, we begin treatment. The course can last from one to three months. Then be sure to take a break for at least 30 days.

Biotin is also used in hair transplant. It is prescribed after the procedure. The element reduces the temporary loss of transplanted strands. It also helps them grow faster. The dosage is selected individually. Vitamin biotin for hair is taken by the patient in its pure form. This may be liquid from an ampoule or tablet.

Reviews: “Hair grows with a bang and the color becomes brighter”

Recently, after stress, my hair began to fall out. The analyzes were normal, but the doctor recommended drinking a complex of vitamins B. I have no problems with the intestines, the food is healthy and balanced. I surfed the internet and read... Folk dreary and foul-smelling options are not for me (purely IMHO, I don’t impose my opinion on anyone).
Eventually:
— I drank a complex of vitamins per month.
- I switched to MoltoBene Marine Grace shampoo-conditioner-mask (this series is specifically against loss, but in general the brand is good).
- I bought and regularly use the Soliton laser comb (the price from the manufacturer is 1.5-2 times lower than from intermediary sellers).
After two months, the hair practically stopped falling out, it lies better and the “undercoat” appeared.
L.Olga, http://forum.awd.ru/viewtopic.php?f=41&t=133822&start=140

I take biotin constantly in a course once a year, and believe me, it’s been tested on myself, the hair grows with a bang this time, and the hair color also becomes brighter! it adds richness and shine to the native pigment! and no matter what anyone says, I see the effect of hair growth only from it! I am skeptical about shampoos with vitamins, I don’t understand at all who believes in it, shampoo has one function - to clean!
Rosalie Parlakyan, http://zdorovyda.ru/biotin-dlya-volos-mifyi-i-realnost/

Greetings, my dear readers. Agree that it is difficult to overestimate the benefits that vitamins bring to the human body. They participate in all processes occurring within us. Therefore, the lack of one of these vitamins affects the work of other elements. Today I want to introduce you to a special component. This is biotin - it is also vitamin B7 or H. Here is such a many-sided "guest" we have today 🙂

It turns out that this element was opened twice. This happened for the first time in 1901. It was then called “biotin” (this is from “bios”, which literally translates as “life”).

But in 1916, biologist Betheman noticed one amazing feature. When he fed fresh egg white to his rats, the animals developed serious health problems. Their hair began to fall out, muscular dystrophy and other misfortunes were observed. But as soon as the scientist introduced boiled yolk into the diet of animals, the condition of the wards immediately improved.

Then scientists looked closely at the boiled yolk and isolated vitamin H from it. It got its name from the German word “haut”, which means “skin”. However, some time later, pundits realized that biotin and vitamin H are one and the same.

Biotin - what is it?

Vitamin H is a water-soluble element that is part of the B vitamin group. Now it is also called vitamin B7. It acts as a coenzyme in the body and is essential for the metabolism of fatty acids and glucose. We eat foods that are sources of fats and... And this vitamin helps convert them and use them to fuel your body with energy.

responsible for blood clotting;

participates in the synthesis of red blood cells;
improves the body's defense system;
has antitumor effects;
normalizes the functioning of the thyroid gland;
takes part in the synthesis of substances that conduct nerve impulses;
very important for hair, nails and skin.

This vitamin is usually added to shampoo for hair growth. By the way, in the article “” I described in detail the effect of this vitamin on our hair. Very positive feedback after taking this item.

Any excess or unused amount of B7 present in the body is excreted in the urine. Because of this, the body does not accumulate biotin reserves. So you should take the vitamin daily to support your body (1).

Deficiency Symptoms

In countries where people eat well and consume enough calories, biotin deficiency is rare. Recommended daily requirements are relatively low.

When a deficiency occurs, the following symptoms occur:

dermatitis, eczema and other skin problems;
unhealthy complexion;
lack of energy, chronic fatigue, mood changes;
digestive problems;
muscle pain, cramps, tingling in the limbs;
cognitive impairment;
anemia;
increased blood glucose levels;
low pressure;
fragility of nail plates;
brittle hair (or hair loss), dandruff;
premature graying of hair.

Many common foods provide the body with biotin. By the way, researchers believe that intestinal bacteria have the ability to independently create this vitamin ( 2 ).

What products contain

Biotin is found in foods such as: meat, eggs, avocados, cauliflower, berries, fish, legumes, and mushrooms. I presented the data in the table at a consumption rate of 50 mcg per day.

However, vitamin B7 is destroyed under unfavorable conditions. Therefore, you need to know how to properly preserve biotin in food. For example, this element is preserved in greater concentration when frozen industrially. There the product is subjected to sharp cooling, and not like in our refrigerator. In canned products, its content is minimal.

Also, prolonged soaking of foods in water has an adverse effect on vitamin H. Therefore, reduce this time to a minimum. Biotin is also destroyed when food is stored in the refrigerator for a long time. Well, it’s like all vitamins.

The lion's share of it is destroyed when foods are fried. Therefore, I advise you to replace this type of heat treatment with boiling. It is better to cook vegetables in their skins, and the pan should be covered with a lid. But baking does not have much effect on the amount of this element.

Instructions for use of biotin

In our country, the following standards for vitamin H intake have been established for children, adolescents and adults.

However, in each specific case, only a doctor can decide on additional biotin administration. They need additional vitamin H ( 3 ):

after a “strict” diet;
during the period of antibacterial therapy;
for gastrointestinal diseases;
women who take contraceptives for a long time;
those working in hazardous industries come into contact with harmful chemical elements;
those who live in cold climates;
those who work hard or are actively involved in sports;
with alcohol addiction.

Vitamin B7 is available in tablets and ampoules, and you can buy it at the pharmacy. The dosage varies, and therefore the price may also vary. It is better to take the drug as prescribed by a doctor. He will describe how to take vitamin B7 and for how long to take it.

You can, of course, use biotin on your own, as it is included in many vitamin and mineral supplements, especially for hair growth. I've been taking these for a month now. Moreover, there are 300 mcg of this vitamin.

This element is water-soluble, so it does not accumulate in the body. Excess is excreted daily from the body with fluid. Therefore, an overdose of vitamin B7 is extremely unlikely.

Signs that the body has an excess of biotin include rapid hair growth (in areas where they are not particularly needed). There may be a deterioration in the condition of the skin, rashes on the skin. You may also experience shortness of breath, increased sweating, or frequent urination. But for this you need to exceed the dosage hundreds of times for a long time.

Health Benefits of Biotin

This vitamin is very beneficial for people. I am sure that the facts given below will convince you of this.

Interaction of biotin with other drugs

Some medicines and food products enhance or, conversely, weaken the action of biotin. In no case should you take anticonvulsants and B7 at the same time - this will reduce the activity of the latter.

But zinc, on the contrary, enhances the effect of taking biotin. In turn, B7 increases bioavailability.

But raw egg white contains a special substance - avidin. It turns out that this is the anti-vitamin biotin. Avidin prevents element B7 from being absorbed into the blood. It is best to take biotin and eat raw protein at different times.

So your “piggy bank” of knowledge has been replenished with information about another vital element. Now you can show off your knowledge in front of your friends. Or just send them a link to the article - they will read it themselves 🙂 Yes, and don't forget. And I tell you: for now.
