Vitamin D, which is what?
Vitamin D, discovered at the beginning of the 2th century, is a group of fat-soluble compounds. The name vitamin D is synonymous with ergocalciferol (vitamin D3) found in plants and fungi, and cholecalciferol (vitamin DXNUMX) found in animal products and synthesized in the skin under the influence of ultraviolet radiation.
Vitamin of the sun
Vitamin D is a prohormone (hormone precursor), commonly known as the sun vitamin, because the main source for the body, covering about 80-90% of the daily requirement for this vitamin, is its skin synthesis under the influence of UVB radiation (Ultraviolet B Radiation) with a wavelength of 295-315 nm.
The efficiency of skin synthesis of vitamin D is influenced by many factors, including: latitude, time of year and day, time of exposure to sunlight, body surface exposed to sunlight, use of creams with UVB filters, age, skin pigmentation or the degree of air pollution or cloudy.
How Much Vitamin D for Children: Newborns and Infants
A newborn child very often receives the first dose of vitamin D while in hospital - because it is currently recommended that all children from 0-6 months of age, regardless of the method of feeding, receive its supplementation. Vitamin D is also recommended for infants aged 6-12 months, and its dose depends on the amount of vitamin D taken by the child with food. When it comes to vitamin D for the newborn, the side effects of vitamin D are the subject of many questions from parents.

Most drugs or supplements available in pharmacies are vitamin D3 suspended in linseed oil, sunflower oil, or safflower oil. Vitamin D for a newborn or infant works best in the form of drops, sprays or twist off capsules, which you just need to "unscrew" and give their contents straight into the baby's mouth or mix it with a small amount of, for example, mother's milk / mixture and give it on a teaspoon.
What Vitamin D for a One-Year-Old Child? Is Supplementation Necessary?

However, if the above conditions are not met, it is recommended to give children of this age vitamin D throughout the year. Its dose depends on the child's body weight and the supply of vitamin D in the diet.
Vitamin D for a one-year-old child can be in the form of not only drops or aerosol, but also water-soluble sachets.
