The standard nutrient reference used for nutrition labeling purposes.
A standardized nutrient reference value used on food labels to indicate what percentage of the daily requirement a serving provides.
The Reference Daily Value (RDV or VDR in French) is a simplified nutrient reference derived from RDA and other official recommendations, used specifically for food labeling. It serves as a baseline value against which manufacturers calculate the percentage daily value shown on nutrition labels. The RDV allows consumers to quickly understand how much of their daily nutritional requirement a serving contributes without needing to know exact RDA values. These values are standardized across products and regulated by food authorities to ensure consistency. A single RDV typically applies to all adults, though some countries distinguish between children and adults.
Enables clear, standardized communication of nutrient content on food labels to help consumers make informed dietary choices.
Use percent daily value on labels as a quick reference to assess whether a food is high or low in specific nutrients. Remember that individual needs may differ from the standardized VDR values. Always check serving sizes when comparing percent daily values between products.
VDR standardizes nutrient references on food labels to help consumers understand daily nutritional contributions.
