When one suffers from hypothyroidism and that has finally struggled to find the treatment that we balance ... but it feels a little lonely and helpless as in France, alas! natural thyroid extract is banned, so help comes from across the Atlantic. Unfortunately we must be able to read English and also understand a little pathophysiology. ! if you have the chance to master about these last two parameters-and not to be too slowed thyroiditis - this book is a response to a lot of practical questions: why the natural thyroid extract works best, how use it, how to control the wealth of information taken etc..Une reassuring! A wealth of references to other sources of information on the same subject. Thank you thank you to the authors and the founder of the STM website, I have their lot!
