Your body temps are low and iodine did not help… checked lately?
Thyroid hormones are low and TSH high.
fT3 should be close to mark supporting body temps, but not working out that way.
Are you using a statin drug?
Mitochondria may be slow. Possible nutrient deficiency. fT3 used to regulate body temp and fT3 regulates mitochondria that make ATP, the energy source for your cells. Mitochondria need CoQ10, made in the liver. So fT3 regulates and CoQ10 enables. You can supplement CoQ10, suggest 50mg UBIQUINOL form of CoQ10, be very careful about that spelling as other forms look similar at a glance. The concern with statin drugs is that they can make major reductions in CoQ10 production in some people.
Your thyroid lab looks like a lack of iodine.
Were you and are you now getting selenium as part of a multi-vit that lists iodine+selenium?
