DHA (docosahexaenoic acid) is an omega-3 fatty acid often recommended to women during pregnancy. Thought to protect against a number of pregnancy-related complications, DHA is also said to promote the health of the developing child.
Most people, including pregnant women, are not getting nearly enough omega-3 from their diet (33, 34). Omega-3 fatty acids are essential during pregnancy, especially the long-chain omega-3 fatty acids DHA and EPA. These are found in high amounts in seafood, and help build the brain and eyes of the fetus (35).
