EFSA has derived adequate intakes (AIs) for magnesium based on observed exposures in healthy populations. AIs for adults were set at 350 mg/day for men and 300 mg/day for women. For children, AI values range from 80 mg/day (infants aged 7‑11 months) to 300 mg/day (boys aged 10‑17 years). Whole-body calcium to phosphorus ratios meanwhile were the basis of AIs for phosphorus. For adults, the AI is 550 mg/day, and for children AIs range from 160 mg/day (for those aged 7‑11 months) to 640 mg/day (for those aged 11-17 years). For both elements, AIs for adult women are considered applicable to those who are pregnant or breastfeeding.
