Vitamin D-2

Vitamin D-2, also known as ergocalciferol, is a form of vitamin D. It is naturally found in some plants and fungi, such as mushrooms exposed to ultraviolet light. It can also be produced commercially by exposing ergosterol (a compound found in yeast and fungi) to ultraviolet radiation.

Vitamin D-2 is often added to foods as a nutrient to help fortify them. It is commonly found in plant-based milk alternatives, yogurts, and baked goods like cakes and cupcakes. Manufacturers add it to increase the vitamin D content of these products.

Vitamin D-2 is recognized as safe and effective by the FDA when used as a nutrient in food. The National Academies of Sciences, Engineering, and Medicine have established upper intake levels for vitamin D. Both JECFA and EFSA have evaluated vitamin D-2. While vitamin D is essential for bone health and immune function, research is ongoing regarding optimal intake levels and potential benefits beyond current recommendations.
