New studies show that taking omega 3 fish oil supplements is beneficial to both pregnant women and their developing baby. Omega-3 fatty acids are an essential dietary component and can only be obtained through diet, unlike other nutrients which can be synthesized by the body. While optimal dietary levels have not yet been established, while pregnant the levels required are increased. This nutrient has been studied extensively and shown to be critical for fetal neurodevelopment, timing of gestation, and optimal birth weight as well. Based on these research findings, pregnant women are recommended to consume two sources of these fatty acids per week from foods or supplements.
