According to a new study, taking fish oil supplements during pregnancy can lead to healthier growth in the first six years of a child’s life. In the study, researchers monitored 736 women who took either fish oil or olive oil supplements in the third trimester of their pregnancy until one week after giving birth. They observed that children whose mothers took fish oil had higher total mass, higher lean mass, and higher bone mineral content at age six than the children whose moms consumed an olive oil supplement.
