I almost did not buy this book due to a previous reviewer's remarks. However, since there is little quality information available about alternative treatments for osteoarthritis, I knew I had nothing to lose. What a lucky decision! Karolyn Gazella really presented a wealth of priceless information in a compact, and extremely easy to read book! Ms Gazella melds the expertise of Jason Theodosakis, M.D. concerning the use of glucosamine, in its several forms, with her own hunger to find answers to difficult health questions. I have read other books authored, or co-authored by Ms. Gazella and this one ranks right up there! Karolyn never presents a treatment as a cure-all. She always drives home the fact that any product is a part of a larger whole, and she isn't afraid to tell you what that "whole" is. After all, she speaks from experience.
