ABSTRACT
Many mothers in Western countries are deficient in omega-3 fatty acids but consume too many omega-6s. This increases their risk for depression. The long-chain omega-3s, EPA and DHA, are the only ones that influence depression. Omega-3s have treated even major depression (particularly EPA) in some studies but may be more appropriate as an adjunct therapy. DHA may help prevent depression but does not work as a treatment. It also reduces the risk of preterm birth for mothers with depression, anxiety, stress, or PTSD during pregnancy.
