Ergocalciferol

Ergocalciferol is a form of vitamin D, also known as vitamin D2. It is produced when ergosterol, a compound found in yeast and fungi, is exposed to ultraviolet (UV) light. It is often synthesized for use as a food additive.

Ergocalciferol is added to foods as a nutrient to fortify them with vitamin D. It is commonly found in plant-based milk alternatives, cereals, and some juices. It helps ensure consumers get adequate amounts of this essential vitamin.

Ergocalciferol is recognized as safe and effective by the FDA when used as a nutrient. The FDA has established regulations for its use as a food additive. JECFA and EFSA have evaluated vitamin D forms, including ergocalciferol, and have established acceptable daily intakes. Adequate vitamin D intake is important for bone health and immune function.
