And Vitamin D

Vitamin D is a fat-soluble vitamin that the body needs to absorb calcium and phosphorus. It is naturally found in a few foods, including fatty fish and fortified milk. The body also makes vitamin D when skin is exposed to sunlight.

Manufacturers add vitamin D to foods to help consumers meet their daily intake needs. It is often added to dairy products like milk and yogurt, as well as cereals and orange juice. Fortification helps prevent vitamin D deficiency.

Vitamin D 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 has evaluated vitamin D and set an acceptable daily intake. Adequate vitamin D intake is important for bone health and immune function.
