Vitamin D

Vitamin D is the collective name for ferols, bioactive substances involved in the vital processes of the human body.

This is probably one of the most underrated vitamins because it is completely “free”. Like any vitamin, fat-soluble or water-soluble, it enters the body with food. But food is not the only source of the substance, another name for which is the "vitamin of the sun." It is enough for the rays to touch the skin, as the processes of producing vitamin D are launched in the body. This “solar” element is able to relieve depression, obesity, protect against cancer and diabetes. How he does it and many more interesting facts about vitamin D - below in the article.

How humanity learned about the "sunshine" vitamin

The discovery of vitamin D (calciferol) was preceded by the study of rickets and ways to deal with it. At the beginning of the last century, the problem of this disease was especially relevant for infants and children during the period of active growth. As a result of vitamin-mineral imbalance in patients, the process of natural formation of bone tissue was disrupted, the skeleton was modified.

More than a hundred years ago for treatment rickets used cod liver oil. At that time, scientists already knew about the existence of vitamin A, its beneficial properties and sources, one of which is actually fish oil. At the beginning of the last century, two researchers at once on two continents - European and American - began to look for a cure for rickets. The scientists took dogs as test subjects. Both the American and the British, as a result of the experiments, came to the same conclusion in parallel - animals that consume fish oil do not have problems with bones. And they attributed the miraculous property to the already known vitamin A. But then one of the researchers, already at the final stage of the experiments, decided on another test. The scientist first neutralized vitamin A in fish oil, and then began to give the substance to sick animals. It was assumed that rickets could not be cured with such a medicine. But the unexpected happened: the dogs got rid of the disease. The American-British theory has collapsed. The experiments started from the beginning. This time it's more efficient. The fourth vitamin substance was discovered in 1922 and named after the fourth letter of the Latin alphabet. A little more time passed, and another discovery was made: a person can synthesize calciferol on his own. Then they unveiled a new way to combat rickets - ultraviolet treatment.

Biochemical properties and synthesis

The chemical structure of vitamin D is the formula of a cyclic high molecular weight saturated alcohol, necessary for the proper formation of the skeleton. Calciferol is a fat-soluble compound that has the ability to accumulate in the cells of the body. The main vitamin "depots" are concentrated in subcutaneous fat and liver cells. Formed on the skin under the influence of the sun or after ingestion with food, vitamin D is absorbed first into the blood, then into the kidneys and, combined with calcium, creates a substance - calcitriol (the active form of vitamin D).

Given these abilities, there is every reason to talk about a possible overabundance in the body. And hypervitaminosis is the cause of a number of diseases, just like hypovitaminosis. Although a vitamin deficiency is almost impossible if a person spends at least 60 minutes a day in the sun. And there is a scientific explanation for this.

Vitamin synthesis in the human body occurs as a result of exposure to sunlight on the skin. In conditions of temperate climatic latitudes, nature fully provides a person with a vitamin norm.

Calciferol deficiency is more often diagnosed in people living in the Far North during the polar night. There is also some danger for babies born in winter, since in the first months of life they are less likely to be outside, and even more so under the sun.

One more remark. In order for the body to efficiently form calcitriol, there is a need for calcium. Absorption of a substance into the blood will not occur without fat and bile enzymes. Subject to this natural balance, the body is able to absorb almost 90 percent of the proposed portion of the vitamin, otherwise - a little more than half. This condition applies only to the natural form of the vitamin, synthetic analogues do not need fats and bile.

Factors affecting the efficiency of synthesis

Although the process of vitamin D synthesis in the human body occurs in the same way, everyone absorbs the useful substance in different quantities. The intensity of digestibility depends on a number of factors.

  1. Age. The amount of synthesized calciferol decreases in proportion to the aging of the body.
  2. Skin color. The lighter the skin, the faster and more vitamin a person will receive under the sun's rays.
  3. Ecological situation. Fewer rays needed for synthesis break through polluted air.
  4. The length of solar waves. The most useful sources of vitamin D are rays in the early morning and at sunset. The synthesis of calciferol in plant and animal cells also occurs, only in the form of a provitamin, which, under the influence of light, turns into a vitamin.

How it is absorbed in the body

The same scientists who studied fish oil as a cure for rickets faced a problem: "pure" vitamin D does not affect the disease in any way. A series of experiments showed that certain conditions are needed for the activation of calciferol.

First, the vitamin must make its way to the liver. And already there, having combined with certain substances, it is transformed into a form that the body is able to absorb. Fortunately, the search for these substances did not require much time from scientists, since some developments had already been made after studying vitamin A. In the case of calciferol, fats were also needed to make it “work”. But soon vitamin D puzzled researchers again. It turned out that fat alone was not enough for him. Among other things, to activate the substance, you need food containing calcium and phosphorus, as well as sunlight.

Forms of the vitamin

The name "vitamin D" does not mean one substance, but six at once. All of them have the characteristics of sterols and are designated by the term "vitamer", which means "a kind of vitamin".

So, what is the collective name "vitamin D"? These are:

  • D1 - it is possible to create only in laboratories, this form of vitamin does not occur in nature in its natural form;
  • D2 – ergocalciferol, a substance derived from yeast. In fact, it is a synthetic version of the vitamin. In this form, D2 plays the role of a food additive in bread and milk formulas. Provitamin D2 - ergosterol;
  • D3 – cholecalciferol. This natural form of the vitamin is easily found in animal products. The provitamin for D3 is 7-dehydrocholesterol;
  • D4 - contained in the skin, and under the influence of the sun is transformed into D3;
  • D5 – sitocalciferon. Made from wheat grain oils;
  • D6 – stigmacalciferol. Found in some plant species.

However, of all these forms of calciferol, the body has the greatest need for the fat-soluble forms D2 and D3. They have the highest biological activity, are found in food, withstand thermal influences, and can also be easily synthesized in skin cells under the influence of ultraviolet radiation. Therefore, most often, when talking about vitamin D and its role in the human body, these two vitamers are meant.

It is important to note that the functions and meaning of all vitamers are the same. Their main differences are the method of obtaining and biological activity.

Daily value

Calciferol content in food is indicated by the dosage in micrograms or, according to the international designation, - IU (40 IU is 1 microgram of vitamin D). From the point of view of nutrition, the optimal intake of this beneficial substance should not exceed 15 mcg daily. But, as in the case of other microelements, the daily norm of the drug is determined for each age category separately.

Table of daily dosage
Category Consumption rate
Infants 7.5 – 10 mcg/300-400 IU
Children 2.5-10 mcg/100-400 IU
Adults 2.5-5 mcg/100-200 IU
Pregnant 10 mcg/400 IU
Nursing mothers 10 mcg/400 IU
Older people 10-15 mcg/400-600 IU

However, there are categories that have an increased need for calciferol. These are the people:

  • residents of the north and regions with environmental problems in the atmosphere;
  • night shift workers;
  • recumbent (do not go outside);
  • patients with (chronic) diseases of the kidneys, intestines, gallbladder and liver.

Also, the need for the vitamin increases in women during pregnancy and lactation.

Under optimal conditions, the blood formula should contain D2 and D3 at the level of 10-40 micrograms per liter.

The role of the "sunshine" vitamin in the body

When looking at what vitamin D is good for, the first thing that comes to mind is for bones. But how can this “sunshine” vitamin affect bone quality?

As already mentioned, the main task of vitamin D in the body is to regulate the exchange of calcium and phosphorus in the blood, thereby ensuring the proper development of the musculoskeletal system, normalize the growth of teeth, and take on the role of a prophylactic against rickets. In simple terms, the main task of this substance is to promote the absorption of calcium by the body. Nature has created a person in such a way that 99 percent of all calcium reserves go to the formation of bone tissue and only one percent in the blood “works” for the nervous system. Meanwhile, if the body feels a lack of an element, then first it will satisfy the need of nerve cells for calcium from the reserves, and the rest will be used to form bones and maintain muscles. Even a small deficiency of Ca causes bone disease. The more serious the deficiency, the sadder the consequences (up to cardiac arrest).

Lack of vitamin D is the cause of fragile bones called osteoporosis. Moreover, due to physiological factors, women are more susceptible to this disease. During pregnancy and breastfeeding, mothers deplete the body's vitamin reserves, leading to thinning and brittle bones. By the way, the latest statistics show that 70 percent of fractures are caused by osteoporosis, which means a deficiency of calciferol. After all, only with a sufficient amount of vitamin D, the body will have enough calcium.

But still, one should not forget that vitamin D is just as important for children as it is for adults, since it is responsible for the normal development of the musculoskeletal system. But at the same time, it is incorrect to raise the question of how old you need to monitor the level of a substance in the blood - calciferol is always needed.

Vitamin D and regulation of metabolic processes

".

Among the main functions:

  1. Increases calcium permeability to intestinal cells.
  2. Stimulates the absorption of phosphorus by the intestines, and calcium by the tubules of the kidneys.
  3. Responsible for the process of protein synthesis, which determines the transport of calcium throughout the body along with the blood.
  4. Promotes the process of bone calcification.

Vitamin D is an ideal preventive measure against rickets in infants and older children, and also protects against osteoporosis in adults, is widely known. But the beneficial effect of calciferol on the human body is not limited to this, it has more than a dozen important functions assigned to it.

  1. Due to its ability to influence the blood coagulation process, it promotes faster healing of wounds, in particular after operations.
  2. Normalizes blood pressure, improves blood circulation, prophylactic against leukemia.
  3. Used in nephrology to treat calcium deficiency.
  4. Prevents cancer (particularly reproductive organs), diabetes, arthritis and atherosclerosis.
  5. In combination with vitamins C and A, an excellent strengthening cocktail for immunity. It is part of the therapy for colds, is prescribed for patients with AIDS.
  6. Normalizes the functioning of the thyroid gland, heart and muscles.
  7. Indispensable for lead poisoning (milk and cottage cheese rich in vitamin D will protect against negative influences).
  8. Strengthens the nervous system.
  9. Prevents early aging of the body.
  10. It has a positive effect on the function of kidney and intestinal cells.
  11. Useful for male potency. For men, 10 micrograms of the vitamin daily is enough to ensure high potency, the production of healthy spermatozoa, and prolong sexual intercourse.
  12. Increases resistance to skin diseases, effective in psoriasis.
  13. In cosmetology, it is used as a hair product (accelerating growth).

How to take from nature to the maximum

Calciferol is a vitamin that enters the body not only with food, but also with sunlight. However, knowing only these 2 rules is not enough in order to fully provide yourself with a vitamin. In addition to the basic axioms, it is worth adhering to effective advice from specialists, and neither hypovitaminosis nor an excess of "D" will threaten.

  1. A properly composed menu will help enhance the absorption of calciferol. In particular, foods rich in calcium, phosphorus, vitamins A, E and group B can improve performance. Vitamin E is of particular importance in the absorption of calciferol from dietary sources, as it controls the metabolic processes in the liver, which in turn allows the absorption of vitamin D.
  2. calciferol from food is absorbed only in the presence of fat) and alcoholic beverages.
  3. Eating cereals increases the need for calciferol. Consequently, the child's body, receiving a large number of cereals, needs frequent sunbathing.

In addition, it is important to remember that the combination of calciferol with other vitamins and trace elements can affect the absorption of nutrients:

  • vitamin D + calcium + iron - hypervitaminosis D provokes iron deficiency;
  • magnesium + vitamin D - better absorption of magnesium;
  • Vitamin E deficiency impairs hepatic D-substance metabolism.

The duration of sunbathing

"Food" lack of calciferol is easy to fill with sunbathing. But this does not mean that a few hours of exposure to the sun will benefit the body. On the contrary, tanning with ignoring the rules is fraught with serious consequences. There must be a measure in everything, even in the light of the sun.

A third of the daily requirement for a vitamin is easily obtained after a 20-minute sunbath. But in the summer, it is important to carry out the procedure in the morning (until 10.00) and in the evening (after 17.00). At this time, solar radiation is non-aggressive, does not cause burns, and the beam length is optimal for the consumption of nutrients from the luminary.

It is important that you do not have to go to the beach to sunbathe. On warm days, it is enough to open your arms, legs, face and neck to the sun for at least half an hour.

In the summer, many of us spend several hours in a row in the sun. This is especially true for vacationers on the seashore. It would seem: well, they will replenish the reserves of calciferol for the entire coming year. But, paradoxically, no. They don't get much vitamin D from the sun. And all because they do not know how to take sunbathing with benefit.

To understand what is wrong with a tan on the seashore, first you need to remember the biological processes of vitamin production by the body. So, under the influence of the sun, subcutaneous fat produces vitamin D, then, already enriched with a useful substance, it is absorbed back by the skin. Now let's remember another fact. People who spend hours under the scorching sun usually do not go to the beach without protective sunscreen, and immediately go to the shower after sunbathing. From this, sunbathing becomes ineffective, since, firstly, the protective cream plays the role of a barrier between the skin and ultraviolet radiation, and secondly, the subcutaneous fat enriched with the vitamin does not have time to be absorbed into the body - it is immediately washed off.

Sun rays that break through layers of clothing or warm through glass also have no effect.

Food Sources of Vitamin D

To make up for your daily vitamin D intake with food, you need to know exactly which foods contain the vitamin. The daily norm of calciferol contains, for example, 150 grams of salmon. However, most of the vitamin is in fish oil, well known to many since childhood.

Fans of fish and seafood, wanting to replenish vitamin reserves, should eat more herring, sardines, tuna, trout, mackerel, caviar and sea fish of fatty varieties, especially their liver, as well as algae.

If a fortified diet is intended for children or for a nursing mother, it is important to include foods rich in both calcium and D3 in the menu. They are found in goat and sheep milk, sour cream, kefir, cottage cheese, natural yogurt, eggs, butter.

An important source of calciferol for meat-eaters is the liver, as well as fatty pork, duck. But vegetarians can get vitamin D from mushrooms, yeast, cereals, soy, parsley, nettle, alfalfa, horsetail.

And sun deficiency can be dangerous

Lack of the “sunshine” vitamin leads to the inability of the body to absorb calcium from food. And this is fraught with serious health problems, especially for newborns and children under one year old, whose body needs calciferol for normal development and growth. Severe vitamin D deficiency is always tooth decay, caries, arrhythmias, and many other problems caused by calcium and vitamin D deficiency.

Only a blood test done in the laboratory using necessary chemicals. But if the deficiency of the substance is large and has been going on for a long time, this will certainly manifest itself in external signs.

Symptoms in adults:

  • joint diseases, arthrosis, arthritis, osteoporosis;
  • ​​
  • dental problems, brittle teeth;
  • dramatic weight loss and lack of appetite;
  • insomnia, nervousness, memory impairment;
  • depression;
  • burning in mouth and throat;
  • loss of visual acuity;
  • indigestion;
  • Crohn's disease and other intestinal disorders;
  • muscle pain.

Signs of deficiency in children:

  • stunting;
  • curvature of the spine;
  • rickets;
  • bone fragility.

Health problems in adults caused by vitamin D deficiency usually resolve when the body achieves a balance of essential vitamins and micronutrients.

The dangers of overdosing on calciferol

The enormous health benefits of vitamin D have long been known. The list of its “good deeds” for a person includes various functions: from a positive effect on nerve cells to preventing the formation of malignant tumors. But if we are talking about hypervitaminosis, then in the case of the sun vitamin, this condition is much worse for the body than a lack of calciferol. A number of dangerous consequences for humans are developing.

For starters. If the daily dosage of the vitamin is not observed and the body is actively saturated with a substance from, for example, synthetic sources, the absorption of calcium is significantly enhanced, and it is intensively deposited in the form of hardened salts in organs and tissues. The consequence of this is that "salted" systems begin to malfunction. An overdose of vitamin D often manifests itself in arrhythmias, micronecrosis, malfunctions of the nervous system and heart.

An excess of vitamin D can produce different symptoms - it all depends on the degree of overdose, and it comes in 3 types of complexity.

First-degree overdose

This condition is called mild poisoning without toxicosis. External signs are manifested in frequent urination, thirst, sweating, constipation, painful sensations in the muscles and bones, nervousness and sleep disturbance appear for no apparent reason.

Overdose of the second degree

No longer just a banal allergy, toxic poisoning with all the consequences. And these are: nausea, tachycardia, changes in the blood formula, auscultatory muffled tones in the heart, systolic murmurs are noted.

Third-degree overdose

Severe poisoning causes harm to the body in the form of vomiting (which is difficult to stop), dehydration and sudden weight loss, drowsiness, anxiety, seizures, low blood pressure and arrhythmia attacks. The skin becomes pale, and the extremities are cold, bacterial diseases occur. In extremely severe cases, it is possible to fall into a coma.

What to do with an excess of vitamin D

If it so happened that the body received significantly more calciferol than it needs, everything must be done immediately to quickly eliminate surplus. There are several ways to do this. Which one is better to choose depends on the degree of poisoning.

The easiest way to eliminate the effects of mild poisoning. In this case, it is important to take care of reducing the absorption of vitamin D by the body. Vaseline oil (taken orally) will cope with this task. Vitamins A and E will serve as a barrier to excess calcium, and diuretics will help to quickly remove excess.

Severe poisoning is managed in a similar way, but the treatment program includes stronger drugs that prevent the absorption of excess calcium. If poisoning is accompanied by pathological changes in the nervous, cardiovascular or other systems, appropriate drugs are prescribed in the form of injections and droppers.

How to deal with fish oil for babies

When it comes to vitamin D for children, as long as they eat well and get enough sun, there is no need for additional taking pharmaceutical drugs.

An adequate supply of the vitamin necessary for the development of schoolchildren is easily obtained from food and from the sun. To do this, you need to spend at least an hour every day on the street.

And the children's menu should be composed of animal products and dairy products. As for meat, any child should receive it at least twice a week.

A justified reason for the introduction of pharmaceutical vitamins into the diet can only be the inability to be in the sun and eat foods rich in calciferol. And also, if a curvature of the legs was noticed in the child or doctors diagnosed a disease requiring medical treatment.

Vitamin D for newborns, on the other hand, is currently the subject of heated debate. Adherents of the "old school" persistently cite the example of the experience when "everyone was fed fish oil, and nothing - that's how they grew up!" But at the same time, their opponents remind: babies get everything they need with their mother's milk, so there is no need for additional pharmaceuticals. Especially when it comes to solar vitamin D. Meanwhile, one should not categorically stick to one of the parties, since none of these theories is 100% correct in full. And there are exceptions to even the strictest rules.

So, there is no need to specifically feed the baby with calciferol drops or other form if the nursing mother is on a good diet and the baby spends 30-60 minutes in the sun a day.

But in this light it is worth clarifying two points. First. You can not call "stay in the sun" a walk when the baby lies in a stroller, completely enclosed. If mothers do not want strangers to stare at their baby, you should choose a secluded place away from street dust and noise and open the stroller with the baby for at least an hour. It is important to remember: the sun's rays are useful only in the early and afternoon hours. And the second. The full nutrition of a nursing mother should consist of meat and dairy products, fish and eggs, a variety of vegetables, and do not forget which fruits contain vitamins and microelements that are useful for the baby and mother.

Also, do not worry about the possible lack of vitamins in babies who are on mixed or completely artificial feeding. Baby food of the new generation contains a full range of products necessary for the full development and growth of the baby. Even if the baby, due to various circumstances, spends little time in the sun (born in winter or late autumn) and at the same time eats exclusively mixtures, parents also do not need to worry about the lack of vitamin D in his body. The baby will receive the necessary daily portion with food.

Another thing is if the food for the child is cow, goat or donor milk, or if the nursing mother eats poorly. Then, with the permission of the doctor, you can artificially fortify his diet.

And finally, about the argument: “Why then did our grandmothers feed their babies with fish oil?”. The thing is that the mandatory intake of drugs for the prevention of rickets in infants is a practice established almost half a century ago. Then the diet of nursing mothers, to put it mildly, was not the best, women worked hard and hard, there were no high-quality mixtures, and donor milk for newborns lost all its properties after boiling. In those conditions fish oil was indeed the salvation needed for babies. Today, the situation has changed dramatically and additional intake of vitamin D is possible only as directed by a pediatrician.

When pharmacy vitamin D is appropriate

The pharmacy form of saturated calciferol in our latitudes is used in extreme cases, when neither sunlight nor vitamin-rich foods can help. Typically, the laboratory version of the D-substance is prescribed for:

  • rickets in children and adults;
  • slow fusion of bone tissue after fractures;
  • arthritis, osteoporosis, softening of bone tissue and inflammation of the bone marrow;
  • gastritis, pancreatitis, enteritis, Crohn's disease;
  • lack of calcium and phosphorus in the blood;
  • tuberculosis;
  • psoriasis;
  • muscle diseases;
  • menopause;
  • viral and colds;
  • AIDS.

Little known interesting facts

In recent years, scientists have uncovered many D-secrets and, by thoroughly studying calciferol, learned a lot of interesting things about this vitamin.

For example, few are aware that a lack of calciferol can cause schizophrenia or cause seasonal depression. And to saturate the body with vitamin D, black people require 20 times more sunlight than fair-skinned people.

An overdose of a vitamin through the skin is impossible - a certain amount of a substance is produced on the human body, regardless of the time spent under the rays.

It is enough to take 2-3 sunbaths weekly in order to reduce the risk of diabetes and certain types of cancer by more than 2 times.

In the countries of the North, a solarium will serve as an alternative to natural sunbathing - it stimulates the production of vitamin D by the skin under the influence of ultraviolet rays. In addition, residents of the northern territories are more at risk of cancer than the inhabitants of warm countries. This is due to the level of obtaining vitamin D from the outside.

Tanned and old skin is not able to synthesize vitamin D. And for a therapeutic tan, 15 minutes is enough - the rest of the time spent under the scorching rays is useless for health.

Vitamin D requires fat to be absorbed. This axiom also applies to the skin. Therefore, before taking a sunbath, you should not wash off your skin oil, just as you should not take a shower immediately after sunbathing, it is better to wait 15 minutes.

Natural antioxidants act as sunscreens without affecting the synthesis vitamin D skin. Such properties are possessed by blueberries, pomegranates, acai fruits.

Rural children are less likely to suffer from vitamin D deficiency - the atmosphere in villages is cleaner than in industrial cities, which allows for easier penetration of ultraviolet light.

Vitamin is less absorbed by the body with kidney and liver diseases.

Daily intake of fortified milk will help maintain the minimum required level of calciferol for an adult body.

Drinking tea and coffee in large quantities "deplete" the body's vitamin reserves.

If the diet has been balanced for a long time, then the reserves of vitamin D accumulated in the liver will be enough for the body for 6 months.

Calciferol has the properties of a vitamin and a hormone whose structure is similar to steroid hormones, in particular testosterone.

It turns out that “washing” cats is also associated with a D-substance: animals lick off a vitamin produced on their skin.

Pharmaceutical vitamin D formulations

A pronounced lack of calciferol is the reason to resort to the use of a pharmacy analogue of the “sunshine vitamin”. The pharmaceutical industry offers the drug in various forms:

  • tablets;
  • capsules;
  • oil-based;
  • aqueous solution and others.

Pharmaceuticals are based on natural vitamin forms and synthetic analogues.

Instructions for use will explain how to properly consume vitamin D tablets, in particular before or after meals. Recently, vitamin complexes with calcium and D3 have become popular. They serve as a prophylactic against diseases of the skeleton and bone tissues (osteoporosis, bone tuberculosis, and others). An oily solution of calciferol can be taken orally. In some cases, intramuscular or intravenous injections of the drug are prescribed. And vitamin D in the pharmacological form of an ointment or cream is a remedy for psoriasis.

It is difficult to say which of the listed drugs is best, but there are optimal suggestions for each specific case or disease.

For example, if we are talking exclusively about preventive intake, then it is better to stop your choice on mineral-vitamin complexes in the form of tablets or capsules. As a preventive measure, the course of vitamin D can be extended for several years: after a 3-week intake, take a break for a month or two. When to start a new round - decide together with the doctor, after studying the blood tests in the laboratory. As a treatment program for rickets, taking calciferol lasts a month and a half, then a week break and a repetition. The optimal dosage is 50-125 mcg, but in each case, all the nuances of treatment are determined by the doctor.

For the prevention of rickets, hypovitaminosis, a liquid preparation is suitable - calciferol in oil. This form of medicine is suitable for children. How to give a vitamin solution to a child and what it affects is described in detail in the annotation of the drug. But the best option is to drip vitamin oil on a piece of black bread and eat it slowly.

Both tablet and oil forms of calciferol are taken with or immediately after meals. Ideally, if you combine the intake of vitamin D with the course A, E, C, group B and magnesium and calcium salts.

It is important to have a blood test after each round of medication to make sure the treatment is working and to prevent hypervitaminosis. Laboratory conditions determine the amount of D2 and D3 present in the blood. The optimal concentration of the substance in the blood on an empty stomach is 10-40 mcg / l.

Cosmetic Uses

Much has been said about how important vitamin D is to the human body. Until now, the conversation has been, so to speak, about the inside, but calciferol can also take care of the appearance of a person. In particular, he is able to take care of the beauty and health of the hair.

Like other useful substances, vitamin D can be added to ready-made shampoos, balms, masks and creams, thereby enriching cosmetics with useful substances. For a more effective effect, vitamin cocktails are suitable: in addition to calciferol, use other substances that are useful for hair, for example, vitamins of groups B, A and E. A good effect will be the usual rubbing of an oil solution of vitamin D into the scalp (finger movements are light, massage). Regular vitaminization of hair will give an excellent result in the form of thick, strong and healthy curls, relieve dandruff and itching of the skin on the head.

Vitamin masks for hair

Recipe 1

Despite the simple recipe, this mask is an effective remedy for strengthening hair at home.

Take olive and burdock oil as a base, mix thoroughly and add about half an ampoule of calciferol to the mixture (you can take an oil solution). Rub the product heated to a comfortable temperature into the hair roots and leave for at least an hour. Wash off with warm water. Repeat every week.

Recipe 2

Mix oils: burdock, almond, ylang-ylang and jojoba. Vitaminize the oil base with substances A, E, B1, B2, B6 and D. Apply the prepared mixture to the hair roots, wrap with polyethylene, insulate and leave for 2 hours. Repeat weekly. As a preventive measure - once a month.

Recipe 3

Mix an egg yolk with castor oil and an ampoule of vitamin D. Apply to the scalp and wait at least 15 minutes. Wash off with warm water and a fortified shampoo. Express course - daily for 3 days. Under normal conditions, you can apply once a week.

Conclusion

The most accessible of vitamins - D can rightly be called one of the most important for the body. Many people know that replenishing the body's reserves with this useful substance is as easy as shelling pears - just go outside, but at the same time they forget about the rules that are important for the normal absorption of calciferol. Follow the advice of experts, smile more often at the rays of the sun, and it will thank you with good health.
