EFSA has proposed dietary reference values (DRVs) for copper

The European Food Safety Authority (EFSA) has proposed dietary reference values for copper. Copper is an essential micronutrient that is necessary for electron transfer processes. The draft Scientific Opinion – the latest in EFSA’s ongoing work on DRVs for EU population groups – is now open for public consultation. Copper is a central component of many enzymes, including those involved in neurotransmitter synthesis, in energy metabolism and in cross-linking of collagen and elastin. EFSA’s Panel on Nutrition, Dietetic Products and Allergies derived Adequate Intakes (AIs) based on mean observed intakes in several EU countries. Data from balance studies in adults were used as supportive evidence. The proposed values are:


Group Adequate Intake
Infants 7–11 months 0.4 mg/day*
Males and females 1 to < 3 years 0.7 mg/day
Males and females 3 to <10 years 1.0 mg/day
Males 10 to <18 years 1.3 mg/day
Females 10 to < 18 years 1.1 mg/day
Male adults 1.6 mg/day
Female adults 1.3 mg/day
Pregnant and lactating women 1.5 mg/day

*mg/day = milligrams per day


Some of the main food sources of copper are grains and grain-based products, meat and meat products, starchy roots or tubers, coffee, tea and infusions, and fish and seafood. Interested parties have until 6 August 2015 to comment on the draft Scientific Opinion. A copy of the public consultation document is available at:
