While I think this is a good book for those who would like information on the different toxins, most of the results included do not include any brand names. It will just say "multivitamin" or "chlorella." I bought this book hoping for specific results or grades on different brands. I guess I will just have to rely on Consumer Lab for that. Most of the information in this book was pretty much information already known and talked about on Natural News and Dr Mercola's site. Overall not a terrible book but was definetly hoping for more!
