The Essential Guide to Vitamins, Minerals and Herbal Supplements Kindle Edition

This is one of the best books I have read in a long time. There is no filler, It lists the facts. It gives the pros and cons for every vitamin and mineral including the effects of toxicity, the RDA, what causes deficiency or helps absorption. This book a real good buy. I strongly suggest that you buy it. It is structured in a way that allows you to read it casually or use it as a reference.
