RDA - Recommended Dietary Allowance
DV - Daily Value.
RDA: ‘Recommended’ daily intakes of a nutrient for healthy people. They are indicators of the suggested intake of that nutrients one should consume on average each day. RDA is developed by the Food and Nutrition Board at the Institute of Medicine of the National Academies. They vary by age, gender, and physical condition. Thus, there are many variants of RDA for each nutrient.
DV: established by the U.S. Food and Drug Administration (FDA), are used on food and dietary supplement labels. For each nutrient, there is one DV for everyone above 4 years. Thus, DV shouldn’t be mistaken for recommended intakes, but to be considered as indicators of how much nutrient a serving of the food or supplement provides in the context of a total daily diet. DVs often match or exceed the RDA for most people, but not in all cases.
