What is added to the food label because people sometimes don't eat ENOUGH of this?

Vitamin D is often added to food labels because many people do not get enough of it through their diet or sunlight exposure. This addition helps to ensure that individuals meet the recommended daily intake, which is important for bone health and overall well-being. Fortified foods can include items like milk, Orange Juice, and cereals, making it easier for consumers to obtain this essential nutrient.
