duration of administration ranged from 8 to 12 weeks. The moderate heterogeneity was detected across the included studies (P<0.00001; I=55%).Using a random effects analysis (n=193), the efficacy effect was 34.6nmol/L (95% CI: 28.6, 40.8). The present meta-analysis showed that food fortification with vitamin D could be an effective tool to prevent and control hypovitaminosis D and Iranian population will most probably benefit from the vitamin D fortification as a national policy.
