They are not the same thing; fish oil contains DHA and EPA. Your body needs both. :)
From Dr. Hale with the InfantRisk Center:
http://www.infantrisk.com/content/non-drug-treatment (this is specifically on depression, but as these essential fatty acids get 'used up' in pregnancy and breastfeeding, mothers become deficient, increasing their chances of PPD and other health issues)
"The long-chain Omega-3 fatty acids, EPA and DHA, have been used successfully to both prevent and treat depression. Both of these are found in fatty fish. EPA is the Omega-3 that actually treats depression because it specifically addresses the physiologic consequences of depression and lowers the stress response. It has been used by itself or has been combined with medications. When it is used with medications, it makes medications work more effectively. The American Psychiatric Association recently recognized EPA as a promising treatment for mood disorders.
DHA helps prevent depression, but studies so far have found that it does not treat it by itself. It is usually combined with EPA. There is a vegetarian source of DHA, but no vegetarian source of EPA; fish oil is still the best source."
"During pregnancy, your baby gets most of his or her food from the foods you eat and vitamins you take.
Omega-3 fatty acids (omega-3s) are an important family of building blocks needed during pregnancy and
breastfeeding. The two most important omega-3s are DHA and EPA. Our bodies cannot make these fatty
acids, so we have to get them from food."
From the medical journal Reviews in Obstetrics and Gynecology:
"Specific to pregnancy, although both DHA and AA appear to be essential to fetal CNS development, the relatively poor intake of EPA coupled with the high intake of linoleic acid (which produces AA), may affect pregnancy outcome by altering the balance of the eicosanoids produced. 2,5,6,14–16 A high ratio of AA to EPA may promote untoward effects such as preterm labor and preeclampsia. 2,17 A linoleic acid-rich diet produces an abundance of AA, which serves as a precursor of the potent 2-series prostaglandins (PGs) E2 and PGF2α, and the vasoconstrictor thromboxane (TX) A2. Both PGE2 and PGF2α are closely associated with the initiation of labor and preterm labor, whereas thromboxane A2has been associated with preeclampsia."
"Because only about 4% to 11% of DHA is retroconverted to EPA,10,11,26 pregnant women who just take DHA supplements, without any dietary EPA, may be unable to produce the right balance of eicosanoids and may limit the transport and uptake of DHA into fetal cells."
