The author would like to correct some misleading sentences, in inclusion criteria number one and two also in table number one, following the original article [1].

Inclusion criteria #1 under the section Study selection, inclusion criteria on page 2 should read “Studies reporting the effects of vitamin D interventions on iron status as primary or secondary outcomes from single or combined vitamin D supplementation with calcium, iron, and vitamin K were considered. No restrictions were placed on the gender, race, and geographical distribution of the individuals enrolled in the study.”

Inclusion criteria #2 should read “All types of vitamin D supplementation”
