This is an excellent book. It covers all the options for thyroid treatment, proper testing, and the co-factors that contribute to optimal thyroid levels and relieve us of low thyroid symptoms.
I also have Recovering With T3, and the CT3M Handbook. All are excellent resources.
Paul is a great researcher, and it shows in his books. They are based on the latest thyroid research that many doctors fail to avail themselves of, relying instead on outdated or false information supplied to them by the drug reps who push T4 only treatment, which fails most of us. Paul knows firsthand the importance of having adequate T3 in our bodies.
