Daily Value (DV) are the recommended amounts of nutrients to consume, or not to exceed each day, to make informed choices. Percent Daily Value (%DV) is how much a nutrient in a single serving of an individual packaged food or dietary supplement, contributes to your daily diet.
The DVs for many nutrients have been updated based on new nutrition research. As a result, you may need to consume more or less of a certain food, beverage or dietary supplement in order to meet the DVs or the recommended amounts.
Nutrition Facts Label
The Nutrition Facts label must list total fat, saturated fat, trans fat, cholesterol, sodium, total carbohydrate, dietary fiber, total sugars, added sugars, protein, and certain vitamins and minerals. While the actual amount and %DV of vitamin D, calcium, iron, and potassium must be listed, other vitamins and minerals may be listed voluntarily by the manufacturer.
However, they are required to list any vitamins and minerals that are added to the food or if a statement is made on the package labeling about their health effects or the amount contained in the food (for example, “high” or “low”).
Supplement Facts Label
Similarly, the Supplement Facts label is required to list the same nutrients as the Nutrition Facts label when any of these nutrients are found in the supplement in an amount considered to be greater than zero.
Total calories, calories from fat, total fat, saturated fat, cholesterol, sodium, total carbohydrate, dietary fiber, sugars, protein, vitamin A, vitamin C, calcium, and iron must be listed when they are present in measurable amounts. A measurable amount is an amount that exceeds the amount that can be declared as “zero”.
