I have been researching the use of omega 3’s in the treatment of depression, anxiety, and bipolar disorder. The current studies agree that high doses of EPA work well to treat mood disorders. DHA is another omega 3 and works better for cognition and fetal/infant development. Studies show that supplementing with only EPA or higher doses of EPA than DHA work best for mood disorder.
I just had a baby and have been taking 1 gram of DHA throughout my pregnancy. I will continue this dose until I am done breatfeeding. I have also been taking 500 mg of EPA. Now I am increasing my EPA dose to 2 grams. I am hoping this will help with postpartum depression, which I had badly with my 3 previous children. I will keep you posted as to my progress with this increase. Here is some helpful information about EPA for depression, suggested doses, and relevant studies.
