Supplements, hm. I honestly don't know enough about vitamins either way, I've mostly just never bothered with them because I didn't think I particularly needed to.

I am pretty sceptical about most "omg take this and it makes you healthy!" recommendations, though, which comes from being chronically ill and having tried out way too much snake oil because others around me insisted I give it a try. At this point I am not really willing to consider new treatments unless there's some really good, reliable, properly-carried-out research backing it up. I'd probably be willing to consider research carried out overseas, yes, if I seemed like good research (ie, not a study with only five people taking part, not something where the results could be due to several factors, etc).

I do take iron supplements, but... that's because my doctor suggested it, and it seemed a fairly reasonable response to me having mild iron-deficiency anaemia.

And I'm sure it's fine to ask as many questions as you like. :) but as for Dreamwidth, all I can say is that I hope it does take off because I really like the features and community so far.
