After reading here on PH about the benefits of magnesium, and realizing I need more iodine, I went to the local store that sells lots of supplements. (It is a grocery store.) The woman who works in the supplement section seemed very, very knowledgeable and helpful, and I asked her how she learned all of it, to which she replied she simply has always been interested in it and it is the culmination of lots of reading.
[Note: I understand that a number of folks discourage any supplementation, and feel that ALL nutrition can be adequately attained through a varied diet - and while I can appreciate that sentiment, it does not help with my goal of finding reliable and trustworthy information sources.]
So my question is, when you want to learn more about supplements (not brands), and decide what form and dose and even what vitamins/minerals/herbs/etc., where do you turn for reliable information? Is PaleoHacks the best source? Are there specific books that you would recommend, or websites you would refer to?
