Editing Copper (section)

====Dietary recommendations====
The [[U.S. Institute of Medicine]] (IOM) updated the estimated average requirements (EARs) and recommended dietary allowances (RDAs) for copper in 2001. If there is not sufficient information to establish EARs and RDAs, an estimate designated [[Adequate Intake]] (AI) is used instead. The AIs for copper are: 200&nbsp;μg of copper for 0–6-month-old males and females, and 220&nbsp;μg of copper for 7–12-month-old males and females. For both sexes, the RDAs for copper are: 340&nbsp;μg of copper for 1–3 years old, 440&nbsp;μg of copper for 4–8 years old, 700&nbsp;μg of copper for 9–13 years old, 890&nbsp;μg of copper for 14–18 years old and 900&nbsp;μg of copper for ages 19 years and older. For pregnancy, 1,000&nbsp;μg. For lactation, 1,300&nbsp;μg.<ref>[http://www.nationalacademies.org/hmd/~/media/Files/Activity%20Files/Nutrition/DRI-Tables/2_%20RDA%20and%20AI%20Values_Vitamin%20and%20Elements.pdf?la=en Dietary Reference Intakes: RDA and AI for Vitamins and Elements] {{Webarchive|url=https://web.archive.org/web/20181113060244/http://www.nationalacademies.org/hmd/~/media/Files/Activity%20Files/Nutrition/DRI-Tables/2_%20RDA%20and%20AI%20Values_Vitamin%20and%20Elements.pdf?la=en |date=13 November 2018 }} Food and Nutrition Board, Institute of Medicine, National Academies Press, 2011.

In the case of copper, the UL is set at 10&nbsp;mg/day. Collectively the EARs, RDAs, AIs and ULs are referred to as [[Dietary Reference Intake]]s.<ref>Copper.

The [[European Food Safety Authority]] (EFSA) refers to the collective set of information as Dietary Reference Values, with Population Reference Intake (PRI) instead of RDA, and Average Requirement instead of EAR. AI and UL are defined the same as in the United States. For women and men ages 18 and older, the AIs are set at 1.3 and 1.6&nbsp;mg/day, respectively. AIs for pregnancy and lactation is 1.5&nbsp;mg/day. For children ages 1–17 years, the AIs increase with age from 0.7 to 1.3&nbsp;mg/day. These AIs are higher than the U.S. RDAs.<ref>{{cite web |title=Overview on Dietary Reference Values for the EU population as derived by the EFSA Panel on Dietetic Products, Nutrition and Allergies |year=2017 |url=https://www.efsa.europa.eu/sites/default/files/assets/DRV_Summary_tables_jan_17.pdf}}</ref> The European Food Safety Authority reviewed the same safety question and set its UL at 5&nbsp;mg/day, which is half the U.S. value.<ref>{{citation |title=Tolerable Upper Intake Levels For Vitamins And Minerals |publisher=European Food Safety Authority |year=2006 |url=http://www.efsa.europa.eu/sites/default/files/efsa_rep/blobserver_assets/ndatolerableuil.pdf}}</ref>

For U.S. food and dietary supplement labeling purposes, the amount in a serving is expressed as a percent of Daily Value (%DV). For copper labeling purposes, 100% of the Daily Value was 2.0&nbsp;mg, but {{as of|2016|May|27|lc=y|df=US}}, it was revised to 0.9&nbsp;mg to bring it into agreement with the RDA.<ref name="FedReg">{{cite web|url=https://www.gpo.gov/fdsys/pkg/FR-2016-05-27/pdf/2016-11867.pdf |title=Federal Register May 27, 2016 Food Labeling: Revision of the Nutrition and Supplement Facts Labels.
