What was your Synthroid dosage? What were those side effects? What were your thyroid test results and reference ranges shown on the lab report, both before and after the switch to NatureThroid? Did you switch to the 48 mcg of Nature Throid all at once? What are your latest thyroid test results and reference ranges? Have you been tested for Vitamin D, B12, and ferritin? If so, please post results. Also please post the cortisol result and reference range.
Sorry for all the requests but we need more info to try and assess your status.
