Short Description:

Vitamin D3(cholecalciferol) is produced mainly by the body itself. Human skin contains a kind of cholesterol. Exposure to sunlight turns it into vitamin D3. So if a child is exposed to direct sunlight for more than four to six hours, his or her own vitamin D3 synthesis is largely satisfied. In addition, vitamin D3 can be extracted from animal foods. Especially cod liver oil, which is extracted from the livers of Marine fish. In general, it’s not easy to get enough vitamin D3 from food alone, so synthesizing D3 in the body through sunbathing is a particularly important method.
