What the publication reports

Forty-two publications were included. In pooled analyses, ferrous sulfate increased haemoglobin by 0.42 g/dL and ferritin by 12.61 ng/mL on average, but results varied substantially across populations and interventions.

Limits and interpretation

Heterogeneity was moderate and trials differed in baseline iron status, dose and duration. Group averages do not justify unsupervised supplementation: testing, clinical interpretation and the risks of unnecessary iron remain relevant.
