Fish oil contains beneficial omega-3 fatty acids, specifically DHA and EPA, which are important for neurological and early visual development in a fetus during pregnancy, according to the American Pregnancy Association. Many obstetricians encourage pregnant women to take a prenatal supplement that contains fish oil during the course of their pregnancy and after pregnancy if they plan to breastfeed. The majority of fish oils on the market, especially those used in prenatal supplements are refined or highly refined, meaning toxins, mercury and other contaminants have been removed.
Background
Although omega-3s are essential for optimal fetal development, according to the American Pregnancy Association a typical American diet does not contain adequate amounts of omega-3s. Although other types of omega-3s, such as ALA, do provide health benefits, the American Pregnancy Association notes that research indicates DHA and EPA are the most beneficial. Fish oils are one of the best sources of DHA and EPA, and although consuming fish through diet is a good source of omega-3s, fish may contain harmful contaminants that high-quality refined purified fish oil supplements do not.
Benefits
The main reason pregnant women take prenatal supplements containing refined fish oil is because of the benefits to her developing baby. However, pregnant moms will also reap health benefits from consuming omega-3s found in refined fish oils. According to National Institutes of Health online medical encyclopedia Medline Plus, taking fish oil supplements can help reduce high triglyceride levels and reduce your risk for heart disease. When consumed late in pregnancy, fish oil supplements may help reduce the incidence of asthma in infants and children.
Considerations
Always consult with your obstetrician before taking any form of prenatal or fish oil supplement during pregnancy. When choosing a prenatal supplement containing fish oils, look for a quality product that is free of contaminants such as mercury or PCBs. Refined fish oils that meet quality standards such as those imposed by the Norwegian Medical Standard, the Council for Responsible Nutrition and the European Pharmacopoeia Standard do not contain harmful levels contaminants. High-quality fish oils should also be free from a fishy taste or smell.
Dosages
According to Medline Plus, fish oil is likely safe for pregnant and nursing women if taken in doses of 3 g or less per day. The American Pregnancy Association reports that the International Society for the Study of Fatty Acids and Lipids has established a minimum dosage of DHA for pregnant women of 300 mg per day, for optimal fetal health and development.
