What is vitamin D 25-OH for and what functions does it perform?

In the human body, depending on its sex, this substance plays a certain role, which in no case can not be underestimated. To begin, consider the general functions that it performs.

Vitamin D 25-OH is responsible for the transportation of phosphorus and calcium throughout the body, and if phosphorus deficiency is extremely rare, then hypokalemia is a common, but very dangerous anomaly. So, with the lack of this trace element, there is a significant softening of the bone tissue, as a result of which the bones become fragile, brittle. The result of such a deviation can be frequent and multiple fractures, even with minor falls or mechanical stress.

In addition, Vitamin D 25-OH helps:

  • to reduce blood cholesterol levels;
  • reducing the risk of the development of a carcinogenic process in various internal organs and systems;
  • to prevent the development of autoimmune pathologies;
  • stimulation of the immune system, etc.

This vitamin is necessary for all, without exception, therefore, if it is deficient in the body, you should immediately consult a doctor and pass all necessary tests. Without their results, no measures, in particular, the use of medicines containing this substance, are categorically not recommended.

Vitamin D for women

Vitamin D is very important for women of any age, as it takes an active part in the functioning of the reproductive organs. Especially acute is the need for this substance in patients who are on the eve of menopause, or have already stepped over this line. During this period of time there is an intense loss of calcium compounds by the body, which is simply washed away from the cells. The consequence of this, as already noted, are serious bone health problems.

Vitamin D - why do women need it? This substance prevents a serious malfunction in the process of metabolism, which can cause such dangerous pathologies in women as: Polycystic ovarian

  • ;
  • gestational diabetes mellitus, which causes the development of type 2 diabetes;
  • various gynecological pathologies.

Vitamin D is very important for expectant mothers, as well as for the fetus, so pregnant women must be prescribed multivitamin complexes containing this substance.

Vitamin D for children

It is very important to conduct a regular blood test for vitamin D in newborn babies and children up to a year, since during this period of time the bones of the skull are strengthened. The most dangerous disease to which a deficiency of this substance can lead is rickets. This is a dangerous pathology, caused, in particular, by a lack of calcium, which is carried along with the structures of this vitamin.

However, it is not worth thinking that replenishing the balance of this substance is a cure for all diseases. In addition to it, there are many other elements that are important for the normal functioning of the body, so you should not focus only on one of them.

Normal indicators of vitamin D in the blood

The rate of vitamin D in the blood does not directly depend on the sex and age of the patient. Its generally accepted indicators are 75-250 nmol / l. These figures may vary somewhat in one direction or another, depending on the season and the person's diet.

It is important to understand that any deviations from optimal indicators are the reason for conducting additional research. Raising the level of this element, as well as lowering it, is a serious anomaly that can tell about malfunctioning of the internal organs.

As can be seen, the rate of vitamin D in the blood of men, women and children is the same. But the reasons for deviations from the optimal indicators in these groups of patients may differ somewhat, so a special clinical study may be prescribed by a doctor for their accurate determination.

Why lowered vitamin D 25-OH levels?

The causes of low levels of vitamin D in the blood can be different. But often they are associated with serious violations in the work of internal organs. The most common pathologies that can provoke a deficiency of this substance are:

  • impaired kidney function, including kidney failure;
  • acute or chronic liver failure, in which vitamin D 25-OH is lowered;
  • is a chronic deficiency of this substance( rarely, but it happens).

If we talk about relatively innocuous causes of deviations from normal values, then they include:

  • rare sun exposure( the sun's rays are one of the most powerful sources of this substance);
  • taking medications from the group of barbiturates, anti-tuberculosis and laxative drugs;
  • insufficient consumption of food containing the substance.

The rate of vitamin D in the blood of women, men and young children should be maintained by consuming egg yolks, beef liver, sardines, mackerel and other types of fish. Alas, there are very few natural products containing this substance. If we talk about plants, then they do not contain it at all.

In order to maintain the vitamin D rate, fish oil intake is recommended for children. In particular, it concerns cod liver oil. There are also special oral drops of vitamin D3, which is so important for the formation of bones in a newborn baby.

However, any pharmaceutical preparations should be prescribed exclusively by a doctor, since this substance can cause powerful allergic reactions. Such a decision can be made by a doctor only after testing for vitamin D 25-OH.
