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?
It is the consumer reports of supplements. It can help you determine which brand of supplement you can choose over another.
But finding the right supplement or even if you need to is about educating yourself and getting competent advice and care.
