I've been on 6 mg (half an Iodoral tab) of iodine for over a year now and it's offered me benefits in cognition (less brainfog) that's probably attributable to its influence on thyroid function (thyroid hormone *is* tyrosine and iodine working together). I wanted to see how I felt coming off of it, and about a day or two after coming off of it I noticed a strange metallic taste in my mouth, which almost tastes like the iodine itself.
Any thoughts or experience with this? I also have had a few moments of feeling absolutely awful with dissociative-like brainfog and increased fatigue, which seems to have gotten better since trying 1 drop of 2% Lugol's iodine tonight (about 2.5 mg iodine). Perhaps the decrease in TSH (iodine is known to increase TSH without any known effects) from stopping iodine resulted in a temporary hypothyroid state as TSH "revved up" back to its normal state?
