Clinical trials shows that multivitamins during pregnancy improve nutritional status of mothers in the developed world and may reduce the risk of small-for-gestational-age babies.
Improvement in nutrient status relative to the placebo. Markers of iron, folate, thiamin and vitamin D status were all higher during the third trimester in the vitamin group.
A reduction in numbers of small-for-gestational-age (SGA) infants (low birth weight for time of birth) relative to the placebo.
This study is the first clinical trial on maternal nutrition performed in either the UK or developed world to demonstrate that supplementing with a specific multivitamin supplement may help reduce the number of SGA infants born.
