In the U.S. and Canada, the '''Reference Daily Intake''' ('''RDI''') is used in [[nutrition labeling]] on food and dietary supplement products to indicate the daily intake level of a [[nutrient]] that is considered to be sufficient to meet the [[Dietary requirements|requirements]] of 97–98% of healthy individuals in every [[demographic]] in the United States. While developed for the [[US population]], it has been adopted by Canada.<ref name="hc">{{cite web |title=Nutrition labelling – Table of daily values |url=https://www.canada.ca/en/health-canada/services/technical-documents-labelling-requirements/table-daily-values/nutrition-labelling.html |publisher=Health Canada, Government of Canada |access-date=20 March 2024 |date=20 October 2022}}</ref>

The RDI is used to determine the '''Daily Value''' ('''DV''') of foods, which is printed on [[nutrition facts label]]s (as '''%DV''') in the United States and Canada, and is regulated by the [[Food and Drug Administration]] (FDA) and by [[Health Canada]], respectively. The labels "high", "rich in", or "excellent source of" may be used for a food if it contains 20% or more of the DV.<ref name="dv3-24">{{cite web |title=Daily Value on the Nutrition and Supplement Facts Labels |url=https://www.fda.gov/food/nutrition-facts-label/daily-value-nutrition-and-supplement-facts-labels |archive-url=https://web.archive.org/web/20231001072833/https://www.fda.gov/food/nutrition-facts-label/daily-value-nutrition-and-supplement-facts-labels |url-status=dead |archive-date=October 1, 2023 |publisher=US Food and Drug Administration |access-date=20 March 2024 |date=5 March 2024}}</ref> The labels "good source", "contains", or "provides" may be used on a food if it contains between 10% and 20% of the DV,<ref>{{cite web|title=Nutrient content claims for 'good source', 'high', 'more', and 'high potency', Specific Requirements for Nutrient Content Claims.

The Recommended Dietary Allowances (RDAs) were a set of nutrition recommendations that evolved into both the [[Dietary Reference Intake]] (DRI) system of nutrition recommendations (which still defines RDA values) and the RDIs used for food labeling. The first regulations governing U.S. [[nutrition]] labels specified a '''% U.S. RDA''' declaration based on the current RDA values, which had been published in 1968. Later, the % U.S. RDA was renamed the %DV and the RDA values that the %DVs were based on became the RDIs.

The RDAs (and later the RDA values within the DRI) were regularly revised to reflect the latest scientific information, but although the [[nutrition]] labeling regulations were occasionally updated, the existing RDI values were not changed, so that until 2016, many of the DVs used on nutrition facts labels were still based on the outdated RDAs from 1968. In 2016, the Food and Drug Administration published changes to the regulations including updated RDIs and DVs based primarily on the RDAs in the current DRI.<ref>{{Cite web |title=Major Changes Coming to Nutrition Facts and Supplement Facts Labels Near You {{!}} Insights {{!}} Venable LLP |url=https://www.venable.com/insights/publications/2016/05/major-changes-coming-to-nutrition-facts-and-supple |access-date=2023-05-11 |website=www.venable.com |language=en}}</ref>
