I asked a pharmacist about this because I also heard of it. He said that if you take a multi-vitamin that is all you need. If you take the fish oil on top of it your wasting your money because your body will only absorb what it needs and dispose of the rest. Made sense to me. Once I started to exercise and take my multi-vitamin the depression and anxiety is slim to none. Of course I take Lexapro also. Good luck.
