Cut use of high-dose iron for mild deficiency: expert guide

New evidence-based advice is to maximise absorption with a low-dose oral regimen

And dividing a high dose into twice or thrice daily doses is “physiologically inefficient” and does nothing to improve iron absorption, the Australian researchers say.
