Vitamins And Minerals: Cholecalciferol

Cholecalciferol is a form of Vitamin D, also known as Vitamin D3. It is naturally produced in the skin of animals, including humans, when exposed to sunlight. In food production, it is often synthesized or derived from animal sources like lanolin (from sheep's wool).

Cholecalciferol is added to foods as a nutrient to fortify them with Vitamin D, which is essential for calcium absorption and bone health. It is commonly found in dairy products like milk and yogurt, cereals, orange juice, and baked goods such as cookies.

Cholecalciferol is generally recognized as safe (GRAS) by the FDA when used as a nutrient. Vitamin D plays a crucial role in bone health by aiding calcium absorption. The National Academies of Sciences, Engineering, and Medicine have established upper intake levels for Vitamin D. JECFA has evaluated Vitamin D and set an acceptable daily intake. While essential, excessive intake of Vitamin D can lead to hypercalcemia, a condition of too much calcium in the blood.
