                                According to the Food and Agriculture Organization (FAO), Nutrient Reference Values (NRVs) are a set of numerical guidelines for the daily nutrient intake of the average healthy person. When a supplement label displays '200 NRV,' it indicates that a single serving provides twice the recommended daily amount for that specific vitamin or mineral.
