Amazing things you get to know about here... It did not occurred to me that omega-3 supplements are not synthetic... Ignorance, ignorance...
I have become more and more reluctant of taking supplements unless they were prescribed by a doctor. I guess many are aware of the studies linking reduced health expentancy with intake of 'artificial' vitamins (mainly A, D & E). Obviously, alcoholics are a case where vitamins are generally prescribed.
So I try my best to get vitamins and everything else naturally - Wild Alaskan salmon seems pretty good though!
