- The DVs are the amounts of nutrients people should consume as part of their daily diet. The %DV is how much a certain nutrient in a single serving of food contributes to the daily diet. The recommended amount of folate to consume each day (100% DV) is actually based on the amount needed to prevent anemia (low number of red blood cells). For folate, the %DV shows how much folate in a serving of a food product contributes to a total daily diet. The %DV for folate helps determine if a serving of food is high or low in folate. For example, a serving of food or a supplement containing 25% DV of folate means that one serving contributes 25%, or one-quarter, of the folate needed in the daily diet.
