Vitamin D3, also known as cholecalciferol, is a type of vitamin D that has been shown to be the true active form of vitamin D in the body. There are at least 10 known types of vitamin D, but the most important are vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Cholecalciferol, also known as vitamin D3, is the most important form of vitamin D, which mainly regulates calcium and phosphorus metabolism in the body. Vitamin D3 is converted from 7-dehydrocholesterol in the skin by ultraviolet radiation.

Vitamin D3 is a fat-soluble vitamin known as the "sunshine vitamin" because most people can synthesize their own vitamin D from UV rays and cholesterol in the skin when the skin is moderately exposed to sunlight. It is mainly synthesized by the human body itself, and the human skin contains a type of cholesterol, which becomes vitamin D3 when exposed to sunlight. Therefore, if the child can fully receive direct sunlight on the skin for more than 4 to 6 hours, the vitamin D3 synthesized by itself can basically meet the needs.
