Vitamin D3 (cholecalciferol) is mainly synthesized by the body itself. The skin of the human body contains a kind of cholesterol,which becomes vitamin D3 when exposed to sunlight. So if a child is exposed to direct sunlight for more than 4-6 hours, his or herown vitamin D3 synthesis will be basically satisfied.
In addition, Vitamin D3 can be derived from animal foods, such as liver,especially fish liver oil, which is extracted from the liver of Marine fish. In general, getting enough vitamin D3 from food alone is not easy, so synthesizing vitamin D3 in the body through sunbathing is a particularly important way.
