what is serotonin? this is somewhat related to the other question that was asked but I think may be even more complicated as the experts don't really know as far as I can tell. so maybe the question should be how do you find out good information about it? if you do a google search you'll get a million hits as it's connected to everything. if you go to a health food store or even a grocery store you'll see it advertized in most of the supplements and now a lot of food products make it a selling point and those HTP initials carry their own magic. If you ask a doctor he'll say one thing and if you ask a pharmacist he'll say another. I don't really want opinions or arguments and I've become increasingly suspicious of webpage information so maybe I'm looking for a book or a webpage from some source that's trustworthy, like webmd or mayo. I also know there is some info from iffgd or unc but this tends to focus on one specific aspect.tom
