Consumerlab.Com's Guide to Buying Vitamins & ... (ISBN 0972969705)

Required reference for anyone using vitamins, herbs, etc.:
There are a lot of guides to Vitamins, Minerals, and Herbal preparations on the market today. What makes "Guide to Buying Vitamins and Supplements" different? For each vitamin, mineral, or herb they gathered samples from multiple brands and put them through a rigorous laboratory analysis. Results of the analysis included products that contained toxic chemicals, had no measurable quantity of the active ingredient, had more of the active ingredient than the acceptable safe levels, and many other surprises. Although many brands were often tested only the ones that passed the laboratory analysis are listed. This is the only place that I have ever seen a listing of product brand names that pass laboratory analysis. Without this guide you really don't know what you are getting when you buy vitamins and supplements. This is a highly recommended read that should be on the shelves of anyone who purchases vitamins and supplements.

Average Book:
This book doesn't supply the results of its tests. If you want the results you still need to subscribe to consumerslab.com. I suggest skipping this book and just subscribe to www.consumerslab.com.

still looking:
This book did not give a description of all supplaments I was looking for. The buying guide was good but I wanted a complete vitamin supplament listing

conslabs rating supplements:
This book provides basic knowledge @ vitamins & herbs, but not very helpful with comparing brands of supplements and potency values.
