Analysis of Herbal Products Shows Contamination Is Common Article www.sciencedaily.com/releases/2013/10/131010205140.htm
This what I was saying the other day - I/we take this stuff (supplements) but there's no way and no one looking out for us to make sure we're even gettin what we're buying.
Might account for some of the differences in people's responses to things (different brands). I really wish there was an FDA type of mandatory testing or something.
60% with "other stuff in it" is rather huge.. and I'm sure they only tested a small sample size so I wonder what a mess it would be if they tested a large amount of different products. And 2/3 with substitutions is also kinda huge..
