Vitamin D3. 5 Live Active Cultures: S

Vitamin D3, also known as cholecalciferol, is a fat-soluble vitamin that helps the body absorb calcium and phosphorus. It is naturally produced in the skin when exposed to sunlight. It can also be obtained from certain foods and supplements, and is often produced commercially by treating lanolin (wool grease) with ultraviolet light.

Vitamin D3 is added to foods as a nutrient to help consumers meet their daily intake recommendations. It is commonly found in dairy products like milk and yogurt, as well as fortified cereals, orange juice, and some plant-based milk alternatives.

In the U.S., Vitamin D is regulated as a nutrient. The National Academies of Sciences, Engineering, and Medicine have established Upper Intake Levels (ULs) for vitamin D. JECFA and EFSA have also evaluated vitamin D and set acceptable daily intakes. Adequate vitamin D intake is important for bone health and immune function. However, very high intakes can lead to adverse health effects.
