What is the Ideal Content of DHA and EPA in Fish Oil?

A: I prefer a higher ratio of DHA to EPA simply due to the fact that the DHA conversion is limited from EPA in the body and DHA is such a vital structural component in the central nervous system. Of course EPA is also vital for prostaglandin synthesis, so that shouldn’t be ignored. If there were a 1:1 oil I would think that to be ideal, but usually what I do is either mix cod liver (high DHA) with regular fish oil (high EPA), or simply rotate taking them on a daily basis.
