Vitamin D3. 6 Live Active Cultures: S

Vitamin D3, also known as cholecalciferol, is a fat-soluble vitamin that helps the body absorb calcium. It is naturally produced in the skin when exposed to sunlight. It can also be obtained from certain foods or taken as a dietary supplement.

Manufacturers add vitamin D3 to foods to increase their nutritional value, as it is often lacking in the typical American diet. It is commonly added to dairy products like milk and yogurt, as well as some cereals and orange juices.

Vitamin D is essential for bone health and immune function. The U.S. National Academies of Sciences, Engineering, and Medicine have established Upper Intake Levels (ULs) for vitamin D. The FDA considers vitamin D a nutrient that can be added to foods. Both JECFA and EFSA have evaluated vitamin D. Evidence suggests adequate vitamin D intake is important for overall health, though research continues on optimal levels and potential benefits for various conditions.
