gaba supplement for anxiety hypothyroid and medications

Answer 1

I was told by my doctor that I have hypothyroidism and also have abnormally high TSH andtibody levels. For this, he has prescribed Synthroid and also said that "to fool" the thryoid to attack something else other than itself, begin taking 200 mcg of Selenium and 1,000 mcg of PABA. Can you please comment on the role that these supplements play in supporting and treating thyoid conditions? Thank you.
