Vitamin D31

Vitamin D3, also known as cholecalciferol, is a fat-soluble vitamin that plays a crucial role in calcium absorption and bone health. It is naturally produced in the skin when exposed to sunlight and can also be found in some animal-based foods. In food production, it is often added as a supplement and can be synthesized or derived from animal sources like lanolin.

Vitamin D3 is added to foods to increase their vitamin D content, helping consumers meet their daily requirements. It is commonly found in fortified dairy products, cereals, and plant-based milk alternatives. Manufacturers add it to support bone health and overall well-being, as vitamin D is essential for calcium and phosphorus absorption.

Vitamin D3 is generally recognized as safe (GRAS) by the FDA when used as a nutrient supplement. 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 linked to numerous health benefits, including bone health and immune function. Very high intakes can lead to adverse effects, but this is rare from food sources alone.
