    Benefits of vitamins of group D

    It is known that vitamin D is divided into two forms, for their designation use the digital indices D2 and D3.The first( ergocalciferol) enters the body only with food, the second( cholecalciferol) is able to form under the influence of sunlight. Due to this feature, D3 is often referred to in the literature as a "vitamin of light".But it is worth considering that ultraviolet does not penetrate the skin through glass, protective creams and tanning sprays, and through clothing.

    • D3 has a beneficial effect on the immune system and contributes to the breakdown of the protein that causes Alzheimer's in elderly people.
    • For women and men of middle and older age, vitamin D intake is very important, since they are at risk for osteoporosis, which, as is known, is not completely cured and is characterized by increased fragility of bones. With osteoporosis any bruises are fraught with fractures or the formation of cracks( nail).Therefore, doctors prescribe such calcium medications in combination with vitamin D.
    • For pregnant women, vitamin D is needed as a preventive measure against the occurrence of rickets in a baby. And even children under 5 years of age are recommended regular intake of this vitamin, especially in winter, when there is little sun. But it is necessary to avoid an overdose in infants - premature overgrowth of the "fontanel" may occur.
    • Dentists for strengthening tooth enamel and dentin are also advised to adhere to the regular use of calcium-containing drugs in combination with vitamin D.
    • As a complex therapy to strengthen the general condition of the body and increase efficiency, vitamin D will do just fine.

    However, any doctor, before prescribing medication, will advise you to try to fill the lack of calcium and vitamin D with food and outdoor recreation. So what kind of food is high in the content of vitamins of group D?Let's consider in more detail. What fruits contain vitamin D?Unfortunately, in the products of plant origin, vitamin D is practically not present. In some fungi, there is a substance ergosterol, which can already be synthesized into vitamin D. in the human body under the action of ultraviolet. Which vegetables contain vitamin D?In an insignificant amount cholecalciferol is found in potatoes, oats, parsley, horsetail, dandelion greens.

    According to doctors, the daily norm of vitamin D is 2.5 μg. In pregnant women and young children, this figure increases to 10 mcg per day.

    But when choosing foods rich in calciferols, the action of the sun should be considered. The organism in the summer sunny day is able to synthesize up to 10 mcg per day with only a half hour walk.

    Overabundance of the vitamin is caused not by products, but by medications taken, their reception must be coordinated with the doctor. Most likely, at signs of an overdose he recommends to you to make a break in therapy.

    Remember that at least 90% of the total volume of vitamin D is synthesized in the body by the action of ultraviolet rays. But before choosing a place for sunburn, make sure that the beach is clean. With polluted air, ultraviolet light passes through the skin badly, and there will be no benefit from such a tan.
