Vitamin D3 (cholecalciferol) is mainly synthesized by the body itself. The skin contains a type of cholesterol that, when exposed
to sunlight, becomes vitamin D3.Therefore, if the child can fully receive direct sunlight more than 4-6 hours, their own synthesis
of vitamin D3, basically can be satisfied.However, due to the rising incidence of skin cancer caused by ultraviolet radiation, air
pollution, and weather changes in different places, people in all countries are receiving less sunshine, and many countries have
set specific rules to limit the amount of sunshine. Therefore, vitamin D deficiency is widespread all over the world.In addition,
vitamin D3 can also be derived from animal foods, such as liver products, especially fish liver oil derived from seafood.Vitamin
D3 in addition to the existence of a few animal foods, mainly in the skin after the formation of 7-dehydrogenated cholesterol
after ultraviolet irradiation, and 7-dehydrogenated choleol is produced by cholesterol conversion, so some people call it the sun
vitamin.

Vitamin D3 is fat-soluble and insoluble in water. It can only be dissolved in fat or fat solvents. It can withstand high
temperature and oxidation in neutral and alkaline solutions.According to the experiment, below 130 degrees condition is heated 90
minutes, its physiology epidemic still is not destroyed, but under acidic condition decompose gradually destroy, in general food
cook add style process, won't lose, but when fatty acid is defeated can cause the destruction of vitamin D3.There are two units of
vitamin D3, namely units of weight and international units.One microgram of D3 equals 40 international units;Or 1 international

Sea liver is the most abundant source of vitamin D3. For example, cod, flounder and swordfish liver contain vitamin D3200~750
micrograms, 500~ 10,000 micrograms and 25,000 micrograms per 100 grams, respectively.Others, such as herring, salmon, sardines and
pomfret, contain small amounts;Livestock livers, eggs and milk also contain small amounts, less than 100 micrograms per 100 grams.
In general, it is not easy to obtain enough vitamin D3 from food alone, so the synthesis of vitamin D3 in vivo by sunbathing is a
particularly important pathway.
