A nutritionist has suggested that I try Gum Guggul as it's supposed to be helpful in converting T4 to T3. My lab work showed that I have a normal fT4 and low fT3, so it seems like a useful supplement if it works. Does anybody have any experience using it, and if so - has it helped or hindered? At the moment, I do not take any thyroid medication. I found out in Jan I have adrenal fatigue, so have been trying to deal with that first and last month I found out I was also hypo.
