Foods such as orange juice and milk are definitely enriched with vitamin D, but these foods are not intended to be good sources of Vitamin D, they are merely foods designed to prevent the most obvious vitamin deficiencies, particularly in children.
Vitamin D will be added to calcium-fortified Minute Maid Premium Home-Squeezed Style orange juice and calcium-fortified Minute Maid Premium Blends: Orange Tangerine; Orange Passion; Orange Strawberry Banana; and Orange Cranberry. The company claims that the taste and appearance of the juices will remain the same.
