I just find it interesting that the low T3/T4 occurs every year for 14 years during the Fall time & rights itself during the other times of the year & wonder if others have observed anything similar. If it stayed low year round, that would be a different story. Could be entirely unrelated to a metabolic change with the prep for winter...maybe not???? All I care about is that I have found strategies to help him so he feels better during this time that haven't caused any negative effects & are economical.
