To support EFSA in the preparatory work for the assessment of Tolerable Upper Intake Levels (UL) for iron, a tailored ‘high level’ protocol was developed. Six systematic reviews (SR) and eight narrative reviews (NR) were conducted to gather contextual evidence relevant to the interpretation of the main body of evidence (BoE). In the SR on iron intake and s‐ferritin, the evidence appraisal of 35 studies revealed an overall low to moderate RoB.
