Vitamin D has many functions in the body. In recent months, its most significant influence on immunity and various immune processes has been best known. Vitamin D contributes to maintaining healthy teeth and proper muscle function. It is involved in the regulation of blood pressure and the growth of blood, muscle and skin cells. To get it, it is not enough to just go out whenever the rays appear or rely on food.

Its most important task is to maintain the right level of calcium and phosphorus in the blood, which is essential for the development and growth of bones in childhood, as well as for their renewal in adulthood and old age. Lack of vitamin D3 leads to a decrease in the level of calcium in the blood, the body begins to take it from the bones and as a result, they "thin out" - i.e. osteoporosis. It also has a significant effect on the health of the cardiovascular system, on brain functions, including the prevention of anxiety and depression. It is involved in hundreds of functions and tasks in the body.

Infants up to 1 year: 400 I.U.

Children under 18: 600 I.U. (with increasing age, the dose increases)

Adults: 1,000 I.U.

Adults: 2,000 I.U. (when activating immune processes)

Pregnant and breastfeeding women: 2,000 I.U.

A LONGER DAY MEANS A GREATER CHANCE TO GET D vitamin

Vitamin D is produced in the skin by the action of solar UVB radiation, which falls on the ground at an angle other than UVA. If UVB hits a specific part of the planet, it depends on what time it is and what the date is. In the temperate zone, which also includes the Slovak Republic, this period begins in early April. Why? The days are getting longer, the sun is traveling over the horizon for a long time and UVB rays have the opportunity to reach us at certain hours. In April, the time variance is only 1-2 hours, around noon. May and June are the longest days and the time period when it is possible to obtain vitamin D from the sun is increasing. Since the end of June, the days have been slowly shortening, the time variance is narrowing, until it disappears completely in mid-September. During autumn and winter, the sun travels too low above the horizon and UVB radiation does not fall on us.

That is why it is necessary to spend maximum time in the sun, especially in spring and summer, and to make the largest possible stocks. Generally speaking, if you go out for about half an hour around noon, it will be the best in terms of vitamin D production. It is important to be free of make-up and sunscreens, which significantly inhibit the production of vitamins. Unfortunately, this recommendation differs from the claims of dermatologists who warn of the harmful effects of UVB radiation on the skin and, conversely, say that you are veiled at this time and use protective creams. It is very difficult to combine the situation so that you create the supply of vitamin D necessary for health and at the same time do not endanger your health in another direction. For people with very fair skin and hair, or with delicate and sensitive skin, this is often impossible.

WHY DO WE HAVE A DEFICIENCY Blanket?

All-day work in confined spaces and lifestyles is why, according to surveys, up to 70% of the population of all ages suffer from vitamin D deficiency, half of which have extremely low levels. You can find out your condition by a blood test with a general practitioner. The reason for vitamin D deficiency may also be smog, which transmits limited amounts of sunlight, as well as the use of sunscreen. Age also plays a role in the process of absorbing the baby from the sun, because the skin of older people has a significantly reduced ability to produce vitamin D when in the sun. Similarly, there are people with naturally higher pigmentation or tanned people whose pigmentation acts as a filter. It is definitely not worthwhile to rely only on the sun.
