Vitamin D Daily Value: Everyone Needs to Know. Vitamin D - what women need it for

Scientists believe that vitamin D3 is the main and most important representative of the fat-soluble vitamins of group D. It is worthwhile to figure out where vitamin D3 is found and why men, women and children need it.

To begin with, I would like to say that this substance is synthesized in the body due to exposure to ultraviolet rays. When the sun is not enough, that is, in the cold season, it is important to replenish its balance by eating food or medicines.

Vitamin D3 - what is it for?

To keep the body functioning properly, it is important to ensure that it receives a sufficient amount of nutrients. Each vitamin and mineral performs its immediate function.

Why does the body need vitamin D3?

  1. To strengthen skeletal system, because it promotes better absorption and magnesium. This substance is involved in the formation of bone and dental tissue. Thanks to the vitamin, the flow of nutrients to the tissue increases, which leads to its strengthening.
  2. For cell growth, taking part in the process of their growth and renewal. Scientists through various studies found that vitamin D3 slows down the process of reproduction of oncological cells of the mammary glands and intestines. It is recommended to use it also in the treatment, as well as the prevention of cancer of the prostate and brain.
  3. For supporting immune system, because this substance affects the work bone marrow, which in turn is responsible for generating immune cells.
  4. For glands to work internal secretion. With the intake of a sufficient amount of vitamin D3, the process of insulin synthesis returns to normal. If this compound is not enough in the body, then the level of glucose in the blood decreases.
  5. For the stable functioning of the nervous system. This useful substance leads to the maintenance of the required concentration of calcium in the blood, and this, in turn, is responsible for the transmission of nerve impulses. In addition, the vitamin helps to restore the protective sheaths of the nerves. That is why it is recommended to take with multiple sclerosis.

Speaking about vitamin D3, it is worth mentioning separately why children need it. Experts prescribe it as a prevention of rickets. Appointed water solution because it is non-toxic. Many mothers are interested in up to what age vitamin DZ should be given, and so the doctor should calculate this period, but usually the reception starts from the first month and lasts up to two to three years. It has to do with what is happening at that time. active formation skeleton. Another important point- how much vitamin D3 should be given to a child. If the baby is of normal weight and is breastfed, then the dosage is 1-2 drops, that is, 500-1000 IU. If there are any deviations, then the doctor prescribes a larger amount of 2-3 drops, that is, 1500-2000 IU, and it is recommended to take vitamin D3 for up to three years. By the way, the dosage for an adult is 600 IU. Since there is a lot of sun in summer and the body produces this compound itself, then the amount is reduced to 500 IU. It is important to consider that if the dosage is exceeded, negative consequences may occur.

What foods contain vitamin D3?

The main suppliers of this compound are dairy products, and there are even special products for children. There is also vitamin D3 in oily fish, for example, herring, tuna, etc. It is important to note that when frying, the amount of nutrients decreases. get it useful compound it is possible from cereals, and first of all it concerns oatmeal.


Hello my dear nutrition experts. I decided to devote today's article to the "solar element" - this is vitamin D3. Its international name is cholecalciferol. This element is very important for the full functioning of the body. Moreover, it is necessary for both adults and kids.

Our body produces most of this important element on its own. This happens by converting sunlight in chemical substances. Under the influence of UV rays, cholecalciferol (well, it is also vitamin D3) is formed in the skin. It then binds to a vitamin D-binding protein and travels to the liver. There he is given the "good" to spread throughout our body. This is such an adventurous story 🙂

This element affects the structure of the skeleton. Also, pressure, immunity, mood, brain function and the ability to protect against cancer depend on its presence ( 1 ).

Vitamin D takes part in various vital processes:

  • regulates, supports the immune and nervous systems;
  • reduces the risk of developing multiple sclerosis;
  • maintains optimal body weight;
  • reduces the severity and frequency of asthma symptoms;
  • reduces the risk of developing rheumatoid arthritis among women;
  • important for bone health;
  • reduces the risk of heart disease, diabetes and certain types of cancer;
  • necessary for the absorption and metabolism of calcium and phosphorus;
  • participates in the work of endocrine glands.

Pharmaceutical derivatives of vitamin D3 are animal products or plant origin. In animal form, it is a more digestible and useful form. It is produced by irradiating animal oils and cholesterol. It is absorbed up to 500 times faster than vegetable analogue. And was rated 4 times more effective.

How long does it take to be in the sun

Up to 95% of this item naturally we can receive from sunlight. Your skin produces vitamin D when it comes into contact with UV rays. That is why it is called the "solar" element. But nowadays, most people experience deficiency symptoms. The two most common reasons for this are:

  1. Frequent stay indoors. Previously, people worked most of the time fresh air and walked a lot. Today we see a different picture. Even children spend too many hours indoors watching TV or playing video games. And most adults work and spend their leisure time indoors. Moreover, being in the shade and cloudy weather can reduce the synthesis of provitamin by 60% ( 2 ).
  2. Applying sunscreen. When we spend time in the sun, many people put on SPF protection. Yes, I will not argue - the risk of developing skin cancer has increased in last years. And doctors strongly recommend using it for children and adults, even during the winter months. But when you apply a cream even with SPF8, the body's ability to produce vitamin D is reduced by 90%. And a product with a higher SPF 30 reduces D3 production by up to 99%.

Therefore, try to be in the sun for at least 15 minutes a day. It is better to do this in the morning. Then the possible negative consequences will be minimized. But you will get a lot of this important vitamin for free 🙂

Deficiency symptoms

Many doctors are beginning to realize that vitamin deficiency is very serious. No wonder it is one of the most recommended supplements, especially for newborns.

For infants and infants, the deficiency of this element is very dangerous. It leads to serious problems. For example, it can provoke the development of rickets chest. Another negative manifestation is that the baby's head develops a square shape. Kyphosis (this is the “frog belly”) and O-shaped legs may also be observed. Schoolchildren low maintenance vitamin D3 is manifested by vision problems and fatigue.

The presence of vitamin D deficiency is difficult to detect. Because the general symptoms are vague, such as fatigue, body aches, or pain. More serious deficiency symptoms are bone pain and general weakness. It is important to remember that sometimes these signs may not appear. That is why it is important to take a blood test to check your levels of this element.

According to studies, vitamin D deficiency can lead to complications of the following diseases:

  • osteoporosis;
  • heart disease and high blood pressure;
  • depression, insomnia;
  • arthritis;
  • diabetes;
  • asthma;
  • multiple sclerosis;
  • psoriasis;
  • fibromyalgia;
  • slow healing fractures.

By the way, this video will tell you a lot of interesting things about the consequences of the deficiency of this element. Take a look.

Best Sources of Vitamin D

The best source is sunlight. Most experts recommend spending at least 10-20 minutes a day in direct sunlight. However, they do not recommend applying sunscreen. So you will get from 1000 IU to 10000 IU. If you are dark-skinned, you will need more time in the sun to get enough of the vitamin. Because dark skin has more protection from sun exposure.

The best time for such sunbathing in summer is before 11 am and after 4 pm. And in winter, go outside more often, especially when the sun comes out.

There is also a category of foods that are rich in the "solar" element. In northern countries, including ours, it is necessary to include these products in your diet. I will give those that contain a large amount of D3. The table below will tell you which foods contain the most cholecalciferol. The percentage is given at a consumption rate of 10 mcg (400 IU).

Because element D is a fat-soluble vitamin, it should ideally be consumed with fat. This is for better absorption of cholecalciferol. For example, you can eat with ghee or vegetable oil, nuts or seeds. Those who live in the Nordic countries (we include them) are additionally recommended to take supplements.

Because it improves calcium absorption, some manufacturers supplement with this mineral in tandem. For example, Calcium D3 Nycomed.

Instructions for use

The lack of a "solar" cell is now a growing problem around the world. It is especially serious in Western and Northern countries. They recently increased the recommended daily intake of vitamin D. Double the amount was prescribed for newborns, children and adolescents.

In our country daily rate of this element is as follows:

For kids

For adults:

Yes, the dosage can be written in different units of measurement - IU or mcg. So know that for vitamin D3 1 mcg = 40 IU.

According to some doctors, the above dosage should be increased significantly. Since we are indoors most of the time and rarely go outside. Yes, and the northern region of residence affects the great need for this element. This is especially true in the autumn-winter-spring periods. Therefore, doctors recommend increasing the rate for adults (women and men) to 800-5000 IU per day.

However, keep in mind that this general recommendations. I am reading now transcend book according to new researches of our organism. The first thing they say is that you need to take an analysis for the norm of vitamins. And I wanted to explore myself. When I pass, I will write you a mini-report 🙂

In addition to multivitamins, I also take an aqueous solution of Aquadetrim for the time being. It was prescribed by my pediatrician for my son. He was born in September and just found the last sunny days. For kids, it is convenient to take. I dilute 1 drop in water, which contains 500 IU. Just the norm for babies. Even if you drop 2 drops, do not worry, the child will not overdose. You can buy in a pharmacy, the price is about 180 rubles.

As I began to study the material about D3, I realized that we are greatly short of it. I decided to find out which one is better to take. I realized that the oil solution is better absorbed, since this vitamin is fat-soluble. Recommended supplements in capsules. So for myself and my husband I will buy something else, and not rub its aqueous solution from the cheese 🙂

Now I buy multivitamins on iherb. They are cheaper than in a pharmacy even with discounts. The same Solgar can be bought 2 times cheaper, plus you can look at the reviews and choose the best option in terms of price / quality ratio. There are different options - with a dosage of 5000 or 10000 IU. How to take and how much is written on the package. Here are some examples

Overdose

It is important to know everything about this element. How much and how to give to babies, as well as how to take adults. The main symptoms of an overdose are as follows:

  • vomiting, nausea;
  • malaise;
  • exhausting headache;
  • sleep disturbance;
  • loss of appetite;
  • pain in the bones and muscles;
  • protein in the urine.

With an overdose of vitamin D3, the level of calcium and phosphorus increases. As a result, the risk of developing pathology of the kidneys, cartilaginous tissues and blood vessels increases.

Although an overdose of this vitamin is very unlikely. Unless you will take it 600,000 IU every day for 3 months. From the sun, we do not have an overdose. Unless, of course, you will lie like a seal on the beach all day. Then nausea, weakness and other symptoms will definitely appear. Although against the background of burnt skin, you are unlikely to notice them 🙂

Top 7 Benefits of Vitamin D

All vitamins are very useful for our health. But this element is worth paying attention to. Special attention. I will give its most basic positive properties.

  1. Promotes bone health. Vitamin D plays an important role in the absorption of calcium into the bones. D deficiency can lead to softening of the bones or rickets. It also increases the risk of osteoporosis and bone fractures. Studies have shown that D improves musculoskeletal health and reduces falls and fractures in the elderly ( 3 ).
  2. Helps regulate sugar levels. Diabetes is a consequence of a lack of insulin or insufficient secretion of insulin after an increase in insulin resistance. According to research, vitamin D may help maintain secretion ( 4 ). Supplementation increases insulin sensitivity and helps reduce inflammation. Many studies support the positive role of vitamin D in the prevention and treatment of both types of diabetes ( 5 ).
  3. Protects against cancer. Symptoms of D deficiency are associated with an increased risk of cancer. This is especially true for breast, colon, and prostate cancers ( 6 ). The effect of the vitamin on cancer risk arises from its role in cellular life cycle. And its ability to block excess estrogen plays an important role ( 7 ).
  4. Helps fight heart disease. A growing number of studies point to the fact that a lack of D increases the risk cardiovascular disease. After all, it is involved in the regulation of pressure, cholesterol levels and inflammation. It is not yet fully understood whether vitamin D prevents heart disease. But one thing is known: people with a deficiency of this element are more likely to die from coronary disease hearts.
  5. Improves the immune system. The vitamin plays a role in protecting against colds, influenza and the development of autoimmune conditions. Immune cells contain receptors for vitamin D, which prevents prolonged and excessive inflammatory reactions. After all, inflammation is often the cause of many chronic and autoimmune diseases (8 ).
  6. Improves mood. Element D acts like a hormone within our body, affecting brain function. Its deficiency is directly related to anxiety, mood disorder, depression, insomnia, mood problems in PMS ( 9 ). Low D levels interfere with the proper production of testosterone and estrogen. And this leads to an imbalance, as a result of which many undesirable symptoms appear. Girls who have painful PMS, include D3 supplements in your diet.
  7. Helps with concentration and memory. Several studies have shown that the D element affects the ability to make decisions, concentrate and retain information. People with low level of this vitamin do poorly in exams, have difficulty with tasks that require attention ( 10 ). This is probably why it is so difficult to study, take exams in winter and early spring 🙂

Interaction with other drugs

Due to the intake of barbiturates, the body's need for vitamin D3 increases. Therefore, during the period of therapy, additional supplements of cholecalciferol should be prescribed. Colestipol and cholestyramine have a similar effect on the oily vitamin.

Simultaneous administration of D3 with diuretics increases the risk of hypercalcemia. And if glycosides and D3 are prescribed, there may be disturbances in the work of the heart.

The effectiveness of cholecalciferol is reduced by antiepileptic drugs and glucocorticosteroids. During therapy with antacids containing magnesium or aluminum, and taking D3, the toxicity of the former increases.

Now, my friends, you know what this wonder substance is good for. And you can, if necessary, replenish its reserves in the body with the help of food. In order not to miss anything that I am going to tell you in the next post, . That's all for today: see you soon.

Analysis of the norm of vitamin D in the blood. Laboratory research

You can determine the rate of vitamin D in the blood using a special analysis., which will allow not only to find out its exact level, but also help the doctor prescribe the appropriate treatment.

Obviously, it is not possible to independently make a diagnosis and “prescribe” the right drug and its dosage.

Any patient should remember a few simple rules that will help to obtain objective analysis data:

  • A blood test to determine the norm of vitamin D is given in the morning.
  • Before the procedure, you should not eat food, as this significantly affects the results of the analysis and makes them biased.

The norm of vitamin D in the blood of women, according to medical research, ranges from 10 to 40 mcg / l.

Such a wide range is explained by the fact that, depending on its physiological state, a woman may have a reduced, but still “healthy” vitamin norm.

For example, during pregnancy, when the body is a little depleted, the most high rate during a period of complete rest and the correct flow of all vital processes.

If a lack of group vitamins still occurs and causes physiological inconvenience to a woman, you can make up for it using the following methods.

The norm of vitamin D in the blood in womencan be maintained and improved subject to proper routine day.

Exhausting night shifts at work, constant parties do not bode well, vitamins are consumed especially quickly, because the body does not rest in the dark, but actively works.

Constant ignorance biological clock often leads to hormonal disruptions, beriberi and other serious diseases.

Interesting fact! Women living in northern latitudes, where there is a lack of sunlight and heat, as well as those who neglect walks in the fresh air, are more likely to experience a lack of vitamin D in the blood.

So that don't hide too much from the sun and spend all your free time indoors. The lack of this substance can also be caused by a deficiency of solar energy.

Proper nutrition is the key to the balance of vitamins in the body.

What is vitamin d3

Significance for the body

Musculoskeletal system. Without this substance, the absorption of calcium, which is part of the bones, ligaments, dental tissue, muscles, and blood, is impossible. Its deficiency leads to the leaching of calcium from bone tissue, as a result of which there is a weakening, a change in the structure. This results in osteoporosis. The risk of the disease is especially increased during menopause, when the absorption of nutrients and the production of vitamin D3 deteriorate significantly.

With a weakened immune system, the risk of breast cancer, intestinal cancer, skin diseases (psoriasis), and multiple sclerosis increases.

When the need rises

Signs of deficiency

Symptoms of hypervitaminosis:

  • hypertension;
  • liver enlargement.

Preparations with vitamin d3

Hair loss, tooth sensitivity, flaking of the skin on the face and body, bone pain and a general feeling of depression - all these symptoms of vitamin D deficiency are so familiar and common in women. They are usually caused by a lack certain vitamins and minerals. Vitamin D deficiency is especially common.

Let's take a look at the benefits and harms of vitamin D for women.

Role in the body

Vitamins of group D perform several very important functions for the body at once:

  • regulate the exchange of calcium and phosphorus;
  • transport calcium from the blood to the bones;
  • increase immunity;
  • responsible for the absorption of calcium and phosphorus in the intestine;
  • participates in the process of hormone synthesis.

Calciferols are divided into several types: cholecalciferol (D3), ergocalciferol (D2), D4, sitocalciferol (D5) and stigma-calciferol (D6).

Their main difference lies in the function they perform. special role it is vitamin D2 and D3 that play in the maintenance of life, a significant effect of other types of calciferol on humans has not yet been proven.

Cholecalciferol is a fat-soluble vitamin that is responsible for the absorption of minerals, preservation normal structure bone tissue.

Ergocalciferol, in turn, maintains the optimal concentration of these substances in the body. Consequently, It is necessary to take both types of vitamins at the same time, as they complement each other..

Why is vitamin D useful for women?

Vitamin D intake is very important for female body, because calcium is responsible for the condition of our bones, the regulation of the heart, the transmission of nerve impulses, rapid metabolism and blood clotting.

With its deficiency, a strong deterioration in the condition of the teeth is possible, frequent fractures and injuries, knee pain, bleeding,

hair loss

and brittle nails.

Phosphorus is the main component of teeth and bones, and is also involved in the synthesis of nutrients into energy and in the process of cell division. If there is little phosphorus in the female body, then pain in the bones, general weakness, a decrease in the level of metabolism and rashes on the skin appear.

But it is calciferols that help to assimilate these minerals! Therefore, it is so important to take not only the necessary minerals, but also vitamin D, which will help them assimilate and stay in the body for a long time.

Daily rate

What is the norm of vitamin D for women per day?

The need for calciferol per day is 5 mcg.

Since we get cholecalciferol from food, and ergocalciferol from sunlight, the daily norm of this component for people living in the north can be increased to 10 mcg.

Also daily dose vitamin D3 up to 10 mcg is recommended to be increased for women who rarely go outdoors, are mainly night image life or live in poor environmental conditions.

Girls and girls aged 11 to 20 years should also increase the amount of calciferol to 10 mcg, since in this period of life there is a final stage of the formation of bones and teeth, the development of the female reproductive system, high activity, muscle growth.

Increased need for pregnant and lactating women. It will be 10 mcg per day. This dose is necessary for the normal development of the child and the prevention of the risk of rickets.

The program “Live Healthy” in this video highlights what daily dose of vitamin D is needed:

A blood test helps to show the content of Vitamin D in the body, its deficiency or excess. Usually this procedure is prescribed by an endocrinologist, but if you want to drink any complex, then we advise you not to neglect this analysis either.

Blood collection is performed on an empty stomach, before it you can not eat 8-10 hours. Of the drinks, only pure water can be consumed, since coffee, tea, and especially sweet juices and soda can violate the veracity of the testimony. The cost of the analysis usually ranges from 1.5 to 3 thousand rubles, depending on the place of residence and the medical center itself.

A scale indicating a reduced, very low, normal or excessive level of vitamin D in women in the blood: with readings less than 10 ng / ml, there is a lack of calciferol, 30-100 ng / ml is a normal concentration, more than 100 ng / ml is an excess.

A video about vitamin D will tell you in detail in which cases it is prescribed:

Causes and symptoms of deficiency

Causes of calciferol deficiency are:

  • little variety in food;
  • lack of nutrients in the body;
  • rare exposure to the street in daylight sunlight.

Especially often there is a deficit when girls go on various diets. The most detrimental in this regard can be called mono-diets, during which you need to eat only 1 product, and protein diets.

For our beauty and health, all useful substances must enter the body. You can find cholecalciferol in cod liver, egg yolk, seafood, cottage cheese, butter and cheese.

But ergocalciferol is obtained exclusively from sunlight . Spend more time in the sun, and then you will avoid many problems associated with the lack of this component.

Symptoms of vitamin D deficiency in women are:

  • rickets;
  • softening of the bones;
  • blurred vision;
  • severe bleeding, frequent bruising and bruising;
  • lack of coordination;
  • insomnia;
  • hair loss;
  • increased fragility of nails.

Now you know about the reasons when vitamin D is below normal in women, and the consequences of its long-term deficiency.

Hypervitaminosis is observed very rarely, but among its signs we can distinguish vomiting, convulsions, diarrhea, severe pain in the joints and a sharp increase in pressure.

The video will talk about the consequences of a lack of vitamin D:

  • Duovit

    biologically active supplement with high content vitamins and minerals: ascorbic acid, vitamins D and A, folic acid, calcium, zinc and magnesium. Reception schedule: 1 tablet a day after meals.

  • Calcium D3 Nycomed

    Chewable orange or mint flavored tablets that help replenish calcium deficiency in the body. Vitamin D in this case is needed for the full absorption of the mineral. Dosage: 2 tablets 1 time per day or 1 tablet twice a day.

  • Calcemin

    Another dietary supplement in which D3 is used to better absorb calcium. In addition, calcemin contains zinc, copper and manganese. The complex should be taken 1 tablet per day.

  • Natecal D3

    Chewable tablets with a high content of calcium and cholecalciferol, which regulate the concentration of the mineral in the body and reduce the work of the hormone that washes it out of the bones. How to use: 1-2 tablets daily after meals.

Which drug is better to buy

Choosing a drug that works well is not an easy task. First of all, you it is worth deciding whether you will take vitamin D in a single form or as part of a complex.

Most often, in monopreparations, the concentration of calciferol is increased to 2000 - 10000 IU, which is more than 100, and sometimes even more than 1000% of the norm.

Therefore, such supplements are only suitable for people with a severe deficiency or with diseases associated with this deficiency. Monopreparations are best taken under medical supervision to avoid overdose.

Cholecalciferol in the composition of the complexes has a lower concentration, usually 5-10 mcg (200-400 IU). In addition, vitamin D in such supplements comes as a supplement to calcium for better absorption. That's why, you can take dietary supplements without a doctor's prescription. The main thing is not to exceed your daily allowance.

Daily dosage for therapy

The daily norm of calciferol in the prevention of diseases associated with its deficiency is 500-1000 IU (10-20 mcg). In the presence of diseases such as osteoporosis and hypoparathyroidism, the dosage should be increased to 3000-5000 IU (international units).

It is worth increasing the dosage to such a figure during pregnancy and lactation, because at this time the baby receives all the necessary substances from the mother.

Deficiency can lead to very serious consequences for a child: rickets, osteomalacia, bone deformities.

Deficiency of D3 and D2 is very dangerous. But no less dangerous is its hypervitaminosis, in which a strong deposition of calcium in the internal organs, demineralization of bones and blockage of blood vessels is possible. Therefore, use the drug only in the prescribed dosage!

Calciferols and aging

After 30 years, calcium gradually begins to be washed out of the body. And one of the reasons for this may be a lack of Vitamin D.

After 40-45

This problem is especially aggravated during menopause and after it. Therefore, starting from the age of 40-45 years, women must definitely take vitamin D (calciferol) in the form of a complex.

After 50-55 years

After 50 years, the standard dosage of vitamin D for women - 1000 IU can be increased by 1.5-2.5 times.

For the elderly

Older people should also consume cholecalciferol at this dosage. In addition, after 50 years you need to take biological additives containing calcium.

Of course, special complexes and monopreparations help to fill the deficiency of vitamins. But do not forget to get calciferol from ordinary food: liver, cheese, butter, and also spend at least 20 minutes a day in the sun. And then you can preserve your beauty and health for many years!

Now you know everything about D3 and other D vitamins: why women need them, and what will happen if they are deficient - when the level is lowered.

Who needs and why vitamin D is useful

Vitamin D (or calciferol) is the very substance that is produced in our body under the influence of sunlight. For this, it is also called the "sunshine" vitamin. This element is the main means of treating and preventing rickets. It is familiar to young mothers, pregnant women and the elderly firsthand. What are the benefits and harms of this substance for our body?

Vitamin D is whole group substances. People need two of them - D2 (ergocalciferol) and D3 (cholecalciferol). The group also includes D4, D5, D6.

D3 and D2 are fat-soluble substances, the body is able to accumulate them. At the same time, cholecalciferol is synthesized in the skin under the influence of sunlight, and we can get ergocalciferol only from food.

What is it needed for

The main benefit of vitamin D is that it is responsible for the normal absorption of calcium and phosphorus. It regulates bone density and growth. Thanks to this substance, calcium enters our teeth and strengthens them. The vitamin has another important feature. Without it, calcium and phosphorus are not absorbed, and the lack of these trace elements increases. But this is not the whole benefit that calciferol brings:

  • this substance is an important element in the prevention of skin and cardiovascular diseases;
  • reduces the risk of oncology and inhibits the division of abnormal cells;
  • strengthens the immune system;
  • promotes the growth of muscle mass;
  • regulates the work of the thyroid gland;
  • prevents the formation of blood clots.

As a result medical research It has been proven that D3, which our body synthesizes during sunbathing, is useful in the treatment of psoriasis. In patients, the skin is smoothed, the spots become less noticeable, the itching goes away.

Since calcium is an indispensable substance in the structure of the human nervous system, vitamin D indirectly participates in the transmission of nerve impulses between neurons. Official medicine uses calciferol as part of complex therapy cancerous diseases.

Where do we get vitamin D from?

The main source of calciferol is our skin. The substance is produced in it under the influence of sunlight. To get a daily dose of vitamin, it is enough to spend about thirty minutes in the air. At the same time, the face and hands must be open (in accordance with weather conditions). In summer, it is safe to sunbathe in the morning (before 11 am) and in the evening (after 4 pm). At this time, it is most difficult to get burned and overheat, and the wavelength of light is optimal for the absorption of ultraviolet radiation. In winter, on a sunny day, you can take a longer walk, exposing your skin to warm rays.

D3 is produced under the influence of ultraviolet radiation, which is why its deficiency is acutely felt by residents of northern latitudes and large cities (due to the small amount of time spent outdoors and the high gas content of the atmosphere, which does not let the sun's rays through).

D2 can be obtained from food. For example, it is contained in corn oil, in parsley. However, to get the daily amount beneficial substance, you will have to eat a very large amount of these foods. So a very small part of the solar vitamin comes to us with food. Most the right way make up for the lack of this substance - more often to be in the fresh air.

What does D-hypovitaminosis lead to?

Lack of calciferol, in the first place, leads to bone fragility, premature tooth decay, muscle weakness. Bones can break even from minor trauma. At the same time, they will grow together for a very long time.

In a person with a lack of this substance, immunity weakens, which is why he gets sick more often. Lack of calcium leads to a weakening of the heart muscle, disturbances occur in the work of this organ.

A person with D-hypovitaminosis is haunted by arthritis, and diabetes may even develop. In women, the monthly cycle is disrupted. It is possible to suspect insufficient intake of this substance in the body on the basis of the following symptoms:

  • burning in the mouth and throat;
  • persistent feeling of fatigue;
  • weakness;
  • frequent cramps, tingling in the arms and legs;
  • fragile bones;
  • rapid weight loss;
  • drop in visual acuity;
  • sleep disturbance.

Most often, a lack of calciferol occurs in the following groups of people:

  • having problems with organs digestive system;
  • living in the north;
  • residents of large cities;
  • in those who rarely go out into the open air;
  • in people with dark color skin;
  • expectant mothers and lactating women;
  • in people who eat a large amount of fat;
  • in the elderly;
  • in children under the age of one.

If a small child becomes irritable, moody and lethargic, his sweating increases, then he may have D-hypovitaminosis. It is urgent to show the baby to the pediatrician.

Hypervitaminosis

Since vitamin D is a fat-soluble substance, it is easily accumulated in the body. If a person takes synthetic vitamin supplements, then instead of benefiting, they can cause significant harm to their health. At frequent use this substance in large quantities D-hypervitaminosis develops. Dangerous consequences of this condition:

  • withdrawal from the bones useful minerals with the subsequent development of osteoporosis;
  • accumulation of calcifications in the heart and blood vessels, which leads to atherosclerosis;
  • calcium salts accumulate in soft tissues and in the internal organs, interfere with their work;
  • a person is haunted by nausea, vomiting;
  • on the part of the nervous system, headaches, insomnia, dizziness develop.

An overdose of calciferol can be suspected if a person has the following symptoms:

  • digestive system disorders: constipation, diarrhea, nausea, vomiting;
  • weakness, pain in muscles and joints;
  • headache;
  • fever and pressure, convulsions, shortness of breath.

Calciferol itself is useful, but its overdose is much more dangerous than a deficiency, so do not take this substance on your own. Like any other medicine, it must be prescribed by a doctor. You can independently increase the level of D in the blood in such a way that as a result you will benefit, and not harm yourself, by being in the fresh air more often.

Why do women need vitamin D3. Signs of deficiency and excess

The increased need of the female body for vitamins is associated with the peculiarities of physiology. Blood loss during menstruation, which is more difficult for a woman than for a man, is associated with a high consumption of vitamins and nutrients. Their consumption increases many times during pregnancy, childbirth, breastfeeding. One of the "vitamins of women's health" is vitamin D3, without which the bones weaken, the skin ages faster, and the menstrual cycle is disrupted. The nature of the load on the body in different periods life is changing, which affects the need for this substance.

What is vitamin d3

D3 is one of the substances belonging to the group of "vitamins D". The main components of this group are:

  1. D2 (ergocalciferol). This vitamin is not found in the human body. In yeast and other fungi, as well as in some plants (for example, in parsley), the so-called provitamin D2 (ergosterol) is present. Getting into the human body with plant products, it turns into vitamin D2.
  2. D3 (cholecalciferol). The body receives it in two ways. First, it is formed in the human skin from cholesterol when illuminated with ultraviolet rays. Secondly, it enters the body with food of animal origin. AT herbal products this component is not included.

The action of substances in the body is the same.

Significance for the body

A feature of vitamin D3 is that it plays a dual role in the body:

  1. Regulates the absorption of calcium, magnesium and phosphorus, which is necessary to maintain normal bone tissue. Accelerates the metabolic process, promotes the absorption of compounds of these chemical elements in the intestine.
  2. Acts as a hormone, regulates carbohydrate metabolism.

Action on various body systems

Musculoskeletal system. Without this substance, the absorption of calcium, which is part of the bones, ligaments, dental tissue, muscles, and blood, is impossible. Its deficiency leads to the leaching of calcium from the bone tissue, as a result of which it weakens and changes in structure. This results in osteoporosis. The risk of the disease is especially increased during menopause. when the absorption of nutrients and the production of vitamin D3 are significantly impaired.

It is called an "anti-rachitic" substance. During pregnancy, it is needed to form healthy bones in the fetus, as well as protect the body of the expectant mother from calcium deficiency and its consequences.

Nervous system. The substance provides growth and regeneration nerve cells. The work of the musculoskeletal system, the ability of muscles to contract, depend on the state of the neurons that transmit signals from the brain to the muscles.

The musculoskeletal system. AT adolescence there is a rapid development of the musculoskeletal system, due to which coordination of movements is being established. During this period, the girl's gait is formed, movements become more complicated. There is an increased intake of vitamin D3. Therefore, it is of particular importance good nutrition exposure to sunlight on the skin.

The immune system. D3 is essential for building immune cells. The body's ability to fight infection depends on their content in the blood. Infection leads to female inflammatory diseases, which are the cause of menstrual irregularities, infertility. During pregnancy, infectious diseases lead to wrong development fetus, miscarriage and other complications.

With a weakened immune system, the risk of breast cancer increases. intestines, the occurrence of skin diseases (psoriasis), as well as multiple sclerosis.

Endocrine system. This substance is involved in the regulation of carbohydrate metabolism in the liver, increases the body's sensitivity to insulin, thereby regulating blood glucose levels. Increased sensitivity to insulin is the cause of the production of excess amounts of estrogen in the ovaries. This leads to ovulation disorders, can cause infertility, early menopause. The ability to regulate blood sugar levels and increase tissue sensitivity to insulin can reduce the risk of diabetes.

Vitamin D3 is very necessary for women to improve metabolism, burn fat, reduce body weight, and improve the functioning of the cardiovascular system. This drug is needed for diseases thyroid gland, as the content of calcium and phosphorus in the blood drops sharply.

Daily requirement for women

When the need rises

Vitamin D3 deficiency is usually observed in people living in areas with long winters, few sunny days, cloudy, rainy and foggy areas. Dusty air (climatic or industrial) also makes it difficult for the skin to produce this substance. The need increases in adolescence and old age, as well as during pregnancy and lactation.

Reinforced doses are prescribed in the treatment of bone fractures, diseases of the musculoskeletal system, endocrine, immune systems.

Note: Vitamin D3 is not formed in the skin if it is covered with clothing, smeared with sunscreen. A visit to the solarium allows you to increase its production, but strong ultraviolet radiation contributes to the occurrence of skin cancer.

The causes of vitamin deficiency can be diseases of the stomach and intestines, which make it difficult to digest, as well as vegetarian food, diseases of the liver, organs of the endocrine system.

Signs of deficiency

With a lack of vitamin D3 in a woman, there is fatigue, insomnia, broken bones. Pregnant women may experience leg cramps, drowsiness, joint pain, deterioration of tooth enamel, skin, hair, and nails.

What is dangerous overdose of vitamin D3

This substance is able to accumulate in adipose tissue and gradually consumed as needed. Before prescribing an appointment, its content in the blood is examined. With an excess, excess calcium is formed, which in the form of calcifications (accumulation of salts) is deposited in the vessels, heart, kidneys, and lungs. They can clog arteries and damage tissues.

  • violation of the digestive system: nausea, vomiting, diarrhea, increased thirst, fever;
  • poor urine output, inflammation of the kidneys, traces of blood in the urine, as well as the presence of protein and white blood cells;
  • weakened immunity, frequent colds;
  • the appearance of a bluish tint to the skin;
  • palpitations, arrhythmia;
  • hypertension;
  • liver enlargement.

In the blood, an increased content of calcium, a decrease in the concentration of phosphorus are found.

Are you sure you're getting enough Vitamin D?

Today we will talk about vitamin D, its health and longevity benefits, according to Ray Kurzweil - CTO google and a famous immortalist and futurologist - this is one of the top 3 main anti-aging drugs available today. In this article, I will talk in detail about scientific research vitamin D, confirming this statement, and practical applications.

Vitamin D deficiency

Many have heard about vitamin D and know that it is produced in human skin when exposed to sunlight. It is the only vitamin that is produced in this way in the human body. Vitamin D can be consumed externally through food or drugs. According to statistics, its deficiency is observed in a very large percentage of the population of the entire planet - most of all in the inhabitants of the northern countries, in the world there is a lack of this vitamin in more than a billion people! Even in countries with sufficient intensity of the sun - India, and Pakistan, China, there is a shortage of it. The territory of Russia is located in such a way that it is poorly trained by solar radiation - therefore, the Russians have a very high risk of getting a disadvantage vitamin D.

The need for vitamin D increases in people who drink a lot of tea and coffee.

Vitamin D deficiency disease

Vitamin D deficiency seriously affects health - in children with a lack of this vitamin, diseases can develop: rickets, and beriberi, in which hair will fall out, skin will peel off, growth can greatly slow down. In adults, deficiency can lead to even more serious health problems, and cause the following diseases:

  • Osteoporosis
  • type 2 diabetes
  • Hypertension and disruption of the cardiovascular system
  • Multiple sclerosis and Parkinson's disease
  • Depression and frequent headaches
  • Breast and ovarian cancer in women

Why vitamin D is useful

Ray Kurzweil

If you boost vitamin D in the blood, firstly, you will not get all of these diseases, and secondly, you will be able to feel better, due to the slowing down of the aging process with this vitamin. Ray Kurzweil a well-known person - the technical director of google, one of the most famous supporters of the ideas of life extension, transhumanism and immortalism recommends it as the most important geroprotector for slowing down aging, which is in the top 3 that he takes himself.

Vitamin D - slows down aging

Vitamin D helps to activate the processes of autophagy in the cells of your body, for the study of the processes of autophagy in the body they gave the Nobel Prize in Medicine in 2016, you can read more in this article.

Vitamin D contributes to the activation of telomerase, which in turn can restore the ends of telomere DNA - thereby slowing down aging.

Delays the development of senile diseases:

  • type 2 diabetes
  • The whole complex of cardiovascular diseases
  • autoimmune diseases
  • Prevents age-related dementia
  • Fights cancer
  • Helps in restoring immunity

Formation of vitamin D in the skin

As I have already noted, the main amount of vitamin D is formed in the human skin, from provitamins, the components for the formation of vitamin D are produced in the body from cholesterol, and also come from food. If a person spends enough time in the sun, then most likely he does not have a lack of vitamin D, although there are exceptions - if an elderly person - his skin transforms worse ultraviolet radiation into vitamin D.

What foods contain vitamin D

Vitamin D is found in fatty varieties fish and fish oil, it contains approximately 400 me (international units) in one teaspoon. To get enough vitamin D from food - at least 500 me you need to eat 200 grams of salmon per day, or more than a kilogram of cod - few people consume this amount of fish per day.

Small amount of vitamin D, also found in butter, cheese, liver, cream and fat milk, in egg yolks, fish caviar, some mushrooms, in all these products the content of vitamin D is so minimal that they cannot compensate for the body's need, for example, 100 grams of butter contains - 35 IU, 100 grams of egg yolk - 25, in the liver - 50 me.

Vitamin D cod liver

There is one product rich enough in vitamin D - this is cod liver (mostly available in canned form), it contains a very large amount of it, if you constantly eat cod liver, you can easily get an overdose of this vitamin, cod liver cannot be stored for a long time, and eat in in large numbers- for getting daily allowance vitamin D is enough to eat a piece small size- 20-30 grams. It can be recommended to purchase 1 can of cod liver for a family of 3-4 people, and eat it in a maximum of 2-3 days, then you can not worry about the lack of vitamin D in the body.

How much vitamin D to take to slow down aging?

To slow down aging, you need to consume from 500 to 1000 IU (vitamin D bioavailability is from 60-90%), depending on the season and time of exposure to the sun, as well as age. In the summer, you need to cut down on vitamin D if you spend a lot of time outside the house, exposing your skin to sunlight - although this is also not recommended to be zealous, as solar radiation causes accelerated skin aging - photoaging, which I wrote about in the article.

My vitamin D intake: to give an example of my own course of intake: in the summer I do not take vitamin D at all, I start taking vitamin D in September, at a dosage of 1000 ME (I eat few foods rich in vitamin D) and take about 3-4 months (until December), after that I take a break for a month and after that I resume taking it until I go outside, in the sun more often (I take a break for a month just in case, since the analysis is expensive and it often fails).

Sold in Russian pharmacies cheap drug to slow down aging quadretrim(cholecalciferol), its price is about 200 rubles, and the package is enough for several months of use. AT aquadetrim contains vitamin D in liquid form, 1 drop contains 500 I of vitamin D, it is recommended to take it with a little water in a tablespoon, preferably on an empty stomach. In appearance, it is just a transparent liquid (you can see in the photo below).

Minimum and allowable dosages of vitamin D

Table of dosages of vitamin D (reception during the day) based on Wikipedia data. AT different countries allowable dosage consider various meanings, but more and more research shows that the blood should be as greater value vitamin D.

Overdose Harm - Too Much Vitamin D

The main thing with vitamin D is not to overdo it with the use, because if it is too much, it can adversely affect health. With an excess, calcification of the arteries can develop, their stiffness can increase, which can cause diseases of the cardiovascular system, can provoke the formation of kidney stones. An overdose of vitamin D does not happen overnight, most often it can occur with excessive use of the vitamin for a long time - a month or more.

This study describes the risks with excessive doses of the vitamin:

http://ndt.oxfordjournals.org/content/early/2012/03/18/ndt.gfs046.full

There is evidence that it is too low and too high dosages may affect male reproductive function

The optimal norm of vitamin D in the blood is considered to be a level of 30 ng / ml, which can be determined by doing an analysis (the analysis is called 25-OH vitamin D) - unfortunately, analyzes for vitamins are not included in the list of free medicine, so it remains only to use the services of paid laboratories, there such an analysis costs from 1 thousand rubles.

Symptoms of a vitamin D overdose:

  • Digestive disorders: nausea, diarrhea, or reverse symptoms such as lack of appetite, constipation.
  • Sometimes it becomes difficult to breathe, there is shortness of breath on exertion
  • Muscle pain, headaches, joint pain
  • Convulsive conditions
  • Fever
  • Pressure surges

If an overdose is suspected, it is necessary to immediately cancel the drug, and see if the symptoms disappear, and if they do not disappear, then do an analysis for the content of the vitamin in the blood.

Contraindications for the use of vitamin D:

  • Hyperkalemia
  • Tuberculosis
  • Organic heart disease
  • Acute and chronic diseases of the liver and kidneys

Combination of vitamins D and K

Vitamin D and K

The combination of these two vitamins can provide significant benefits to the health of the body, they form a synergistic complex. Vitamin K controls the calcium balance in the body: it counteracts the deposition of calcium in the walls of the arteries, directing it to its intended purpose - in the bones, teeth and nails, it also has a lot useful properties anti-aging, and even cancer prevention, but its consideration requires a separate article.

At IHERB Life Extension Foundation Life Extension sells complex drug containing vitamin D and K, as well as sea iodine - good combination, you can buy it from the link using my ref code ZPW509 and get a 10% discount on it.

Conclusions: I considered benefits of vitamin D, for health, and use to slow down aging and achieve longevity, this is one of the few anti-aging geroprotectors that can be purchased at a regular pharmacy at a minimal price, I think? worth taking advantage of. Thank you for reading the article, leave comments, ask questions, I will be happy to answer.

To maintain health, it is important for a woman to control the amount of vitamin D in the blood. Especially during the period of bearing a child and in a state of menopause. Its benefits are known. However, not everyone thinks about what role it plays in the body. It is necessary for a woman during pregnancy, during breastfeeding. The state of health, phosphorus-calcium metabolism depends on its quantity in the body.

Vitamin D is a substance produced in human skin, tissues of animals and plants under the influence of the sun or ultraviolet rays. Its Russian synonym is 25-hydroxycalciferol.

The substance group includes:

Vitamin differ depending on the type of origin:

  1. Endogenous. Formed in the skin from provitamin 7-dehydrocholesterol (D 3, cholecalciferol).
  2. Exogenous. Enters the body with food (D 2, ergocalciferol).

Conditions for formation in the body:

  • sunlight or ultraviolet rays;
  • skin color (the lighter, the better the synthesis);
  • age (aging skin practically does not produce vitamin D);
  • the state of the atmosphere (cloudiness, rains prevent synthesis).

Provitamin 7-dehydrocholesterol is converted into cholecalciferol in human skin under the influence of sunlight. In the same place, it binds to protein and in such a tandem enters the bloodstream and the liver.

In the liver, it is converted to 25-hydroxy-cholecalciferol (calcidol). Then, in the kidneys, it is converted into 1,25-dihydroxy-cholecalcifers (calcitriol), that is, into the biologically active form of vitamin D.

Forms D 2 and D 3 are the most common natural compounds. In appearance, it is a white crystalline, powdery, fat-soluble substance that dissolves in ether, chloroform, alcohol, but is insoluble in water. Quantity is measured in international units (IU).

The importance and role of vitamin D in the body

The norm of vitamin D in the blood of women during childbearing is a necessary requirement for the health of the baby and the expectant mother. Its deficiency during pregnancy is fraught with premature birth and multiple complications in both the woman and the baby.

Violation of the balance of vitamin D during menopause entails the development of not only osteoporosis, but also diabetes, allergies of various types and other metabolic diseases. This vitamin, also called solar, acts on the body both as a vitamin and as a hormone.


As a hormone:

  • binding in the intestines with protein, it helps to move potassium in the body;
  • helps to absorb calcium in the kidneys.

As a vitamin:

  • regulates the level of phosphorus and calcium in the blood;
  • protects bone mass, prevents rickets and osteoporosis, increases calcium absorption in the small intestine;
  • reduces susceptibility to cardiovascular skin diseases, oncology, metabolic diseases;
  • prevents muscle weakness;
  • strengthens the immune system;
  • regulates the functioning of the thyroid gland.

Indications for analysis

Vitamin D is synthesized in the body under certain conditions. In addition, the norm in the blood of women of different ages, respectively, is different.

After 45 years, even in the absence visible reasons, endocrinologists recommend monitoring the level of the vitamin, since it is at this time that a person’s ability to receive it with food decreases. Synthesis in the aging skin is significantly reduced.

Vitamin D deficiency is dangerous for the body, especially for women.

Therefore, you should exclude the risk of its development and go through the usual procedure for donating blood for analysis:


How to pass the analysis

For research, blood is taken from a vein or urine. The immunochemiluminescent method of investigation and the Sulkovich test are used, respectively. An appointment for the analysis of "25-OH vitamin D" is given by endocrinologists, general practitioners therapeutic practice, rheumatologists, orthopedists, traumatologists. According to the level of an intermediate product of vitamin D synthesis,

25-hydroxycalciferol, you can judge the level of calciferol in the body and determine the excess or deficiency.

Before research, you should:

  • refrain from smoking;
  • do not eat at least for three hours, it is only allowed to drink water without gas;
  • exclude spicy, salty, fatty foods from the diet on the eve of the tests.

The exact result can be affected by:

  • pregnancy;
  • taking drugs that lower the level of vitamin D in the blood, namely oral anticoagulants, phenyton, phenobarbital, rifampicin;
  • x-ray methods of research, as they change the biochemical composition of the blood.
