None, currently. Was on fish oil for a couple or three years while I was on an extended hospitalization. I don't think it did anything for me. I do not take a multivitamin. I eat tons of fruits and veggies, as I have become nearly vegan (if there is such a thing). I do watch my B12, though.

I was in healthcare for awhile and the smart folks I talked to convinced me that, for most people, a major multivitamin is just creating expensive urine. No idea if that is still common thinking or not. Perhaps I should reconsider.
