Cholecalciferol Vitamin D3

Cholecalciferol is a form of Vitamin D, often called Vitamin D3. It is naturally produced in the skin of humans and animals when exposed to sunlight. It can also be synthesized for use as a food additive.

Cholecalciferol is added to foods as a nutrient to fortify them with Vitamin D. It is commonly found in dairy products like milk and cheese, as well as in cereals, orange juice, and some margarines.

The U.S. Food and Drug Administration (FDA) lists cholecalciferol as Generally Recognized As Safe (GRAS) when used as a nutrient. Vitamin D is essential for bone health and immune function. International bodies like the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated Vitamin D and its forms. Evidence suggests adequate Vitamin D intake supports overall health, but excessive amounts can be harmful.
