just to update my experience - I needed to up my Adrenal support because my thyroid really started working...
and for awhile that worked and then my temps went back to "normal" and then I read this book that I HIGHLY RECOMMEND because this lady actually understands The Big Picture and doesn't push drugs "Hashimoto's Thyroiditis: Lifestyle Interventions for Finding and Treating the Root Cause"
in her book she mentioned the importance of probiotics and when I started those..my temps went up.
so it took the Bladderwrack, adrenal support, AND probiotics...to get the engine running :)
