What it is
Vitamin D yeast is a source of vitamin D produced by exposing yeast to ultraviolet (UV) light. This process causes the yeast to naturally produce vitamin D. The yeast is then typically dried and may be inactivated.
Why it's used
Manufacturers add vitamin D yeast to foods as a source of vitamin D, a nutrient essential for bone health and immune function. It is commonly found in dairy and non-dairy alternatives like yogurt, milk, and cheese, as well as in some baked goods and beverages.
Health notes
Vitamin D yeast is generally recognized as safe (GRAS) by the FDA when used as a nutrient source. Vitamin D is crucial for calcium absorption and bone health. International bodies like JECFA have evaluated vitamin D and established guidelines for its use. While essential, very high intakes of vitamin D can lead to adverse health effects, but this is unlikely from food sources alone.
Allergen info
Yeast is not one of the nine major allergens. Gluten is not typically present unless the yeast is grown on a gluten-containing substrate, which is uncommon for vitamin D yeast.
