Vitamin D Cholecalciferol

Vitamin D cholecalciferol is a form of vitamin D that is naturally produced in the skin when exposed to sunlight. It can also be found in some foods and is often added to fortified foods. It is typically produced commercially through the irradiation of animal-derived lanolin or through plant-based ergosterol.

Manufacturers add vitamin D cholecalciferol to foods to increase their nutritional value, as it is essential for calcium absorption and bone health. It is commonly found in dairy products like milk and yogurt, as well as in cereals, orange juice, and margarine.

Vitamin D cholecalciferol is generally recognized as safe (GRAS) by the FDA when used as a nutrient. The National Academies of Sciences, Engineering, and Medicine have established upper intake levels for vitamin D. JECFA and EFSA have also evaluated vitamin D and its derivatives. At typical intake levels found in fortified foods, it is considered beneficial for bone health. Excessive intake can lead to adverse health effects, but this is rare from food sources alone.
