In the process of recovery, I learned how to use T3 thyroid medication properly and safely. Many doctors are taught that the only necessary thyroid hormone replacement is levothyroxine (synthetic T4) and they never prescribe T3. However, for some thyroid patients, T3 may be the only thyroid hormone that will enable them to regain their health. Some doctors also fear the use of T3 because they mistakenly believe it causes problems like high heart rate or osteoporosis. T3 can cause problems, as can all thyroid hormones, but invariably any problems are caused by its incorrect use. Another medical myth is that thyroid blood tests always reveal actual thyroid hormone activity. In reality, they merely measure circulating thyroid hormone, offering no insight into the efficacy of this thyroid hormone inside our cells.

It is such myths and such doctors that condemn thousands of thyroid patients to a permanent hell of hypothyroidism. T3 is sometimes required as some problems can occur at the cellular level that other thyroid medication cannot correct. In my own case T3 was my salvation. I had gotten to a point in my illness when I had thyroid and adrenal issues. My weight had dropped to two-thirds of my normal body weight and I was passing out with low blood pressure on most days of the week. I was virtually an invalid and slept for four to six hours in the daytime, as well as at night. I could barely move around and getting up the stairs was difficult. My career was lost and in many ways it was very hard on my family.

T3 changed this, but it took me three years to begin to know how to use it properly. In total it took me about 10 years to recover from the start of my hypothyroidism. I lost a decade of my life when my children were young. It then took me another 10 years to be able to reflect on and communicate my experience with T3 and how other people could also use T3, which I did in the form of a book.
