Vitamin D3 Cholecalciferol

Vitamin D3, also known as cholecalciferol, is a fat-soluble vitamin that the body can produce when skin is exposed to sunlight. It is also found naturally in some foods and is often added to fortified foods. It can be produced commercially from lanolin, a wool grease.

Manufacturers add Vitamin D3 to foods to help consumers meet their daily needs for this essential nutrient. It is commonly found in fortified dairy products like milk and yogurt, as well as cereals, orange juice, and plant-based milk alternatives. It helps the body absorb calcium and phosphorus.

Vitamin D3 is recognized as safe and effective by the FDA when used as a nutrient supplement in food. 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. Adequate vitamin D intake is important for bone health and immune function. Most people get enough vitamin D from sunlight and diet, but deficiency can occur.
