EFSA has derived adequate intakes (AIs, the average observed intake by an apparently healthy population that is assumed to be adequate) for copper based on mean observed intakes in healthy populations. For adults, AIs of 1.6 and 1.3 mg/day are proposed for men and women, respectively. For children, AI values range from 0.4 mg/day (infants aged 7-11 months) to 1.3 mg/day (boys aged 10-17 years). For pregnant and breastfeeding women, EFSA derived an AI of 1.5 mg/day.

On the other hand, DRVs for iron were derived using a factorial approach involving measurements in iron turnover and iron losses from the body. For men and post-menopausal women, the population reference intake (PRI, the level of intake that is adequate for virtually all people in a population group) is 11 mg/day; whereas for pre-menopausal women EFSA set a PRI of 16 mg/day. PRIs for infants and children were estimated to range from 7 mg/day (for children aged 1‑6 years) to 13 mg/day (for girls aged 12-17 years).
