Studies
These studies provide scientific insights into Prenatal Multivitamins benefits:
A 2010 BMJ cohort study nested within an RCT context found that periconceptional use of a daily multivitamin containing folic acid, B12, iron, and zinc was associated with a 40 % reduction in congenital malformations compared to no supplement (RR 0.60; 95 % CI: 0.45–0.80).
A 2016 randomized trial in 200 low-income pregnant women showed daily prenatal multivitamin supplementation (including 400 µg folic acid, 18 mg iron, 10 mg zinc) from week 10 to delivery increased mean hemoglobin by 1.2 g/dL versus 0.5 g/dL with iron-only (P < 0.01) and reduced anemia prevalence at term.
A 2014 double-blind RCT in 150 pregnant adolescents found multivitamin supplementation reduced risk of small-for-gestational-age infants by 28 % compared to folic acid alone (RR 0.72; 95 % CI: 0.52–0.99; P = 0.04).
