Omega-3 EFA’s Reduce the Risk of Preterm Births.

Despite the evidence that supplementing omega-3 EFA’s during pregnancy

reduces the risk of preterm births, omega-3’s are not usually included in prenatal

vitamins. This study set out to see if adding them would reduce the risk of

preterm births.

The study included 9,461 pregnant women. It found women who supplemented

omega-3 EFA’s on top of their prenatal vitamins were a significant 36% less likely

to have a preterm birth and 35% less likely to give birth to a baby who was small

for their gestational age.

This study suggests that making omega-3 part of your prenatal supplement

program may help protect against preterm birth.
