Increases blood haemoglobin concentration
ModerateEvidence strength: moderate. Human evidence with one recorded weakness, or capped at moderate by its design or by unread numbers.Findingreplicated ×2“Average follow-up measures of mean hemoglobin assessed after supplementation during pregnancy were found to be significantly higher among women supplemented with VA by 0.35 g/dL [95% CI 0.24, 0.45] (Supplementary Figure 9) and a change in 0.19 g/dL [95% CI 0.06, 0.33] among studies reporting change in hemoglobin levels (Supplementary Figure 10).”
