From what I heard fish oil is a much better source of omega fatty acids than flax seed. I was taking flax seed for awhile and stopped and started taking cod liver oil (Carlson brand) and my depression and loneliness just went away. I feel great, better then I've felt in my life. I've been on 5 different anti-depressant meds in my life time. It pisses me off knowing I've taken all those drugs and the doctors never looked to see if I had any deficiencies, they just wanted their drug money. Anyway my point is I take cod liver oil and love it and truly believe it has cured my depression.
