Synthroid does not work for 99% of people. Synthroid is T4 (inactive thyroid hormone) and if you're already hypothyroid, you won't be able to convert much, if any of that T4 to T3 (active hormone). Personally, I take dessicated thyroid (over the counter) because it contains both and usually also has some T2 and calcitonin. I've also seen people order T3 from Mexico or elsewhere once they understand how to titrate it. Rarely will a doctor prescribe T3, but it never hurts to try. In the last 7-8 years, I've only seen someone prescribed something other than Synthroid a total of 2 times. One of those patients told me she had to fight her doctor to get it prescribed because she "did her own research" and guess what... it helped when Synthroid didn't.
Just FYI, long runs cause large spikes in cortisol and catecholamines which are also known to contribute to diabetes and muscle loss (muscle contributes positively to metabolic rate). I would suggest switching to a few all-out sprints, 2-3x/week instead. Your metabolism and body composition will thank you.
Here is an interesting read on thyroid.
So Synthroid was actually the last thing we tried! We did the compounds, generics, etc. and nothing was working until Synthroid. My levels were good T3 was right where we wanted it T4 was within range as well. My complaint is that my boujee ass body of course "requires" that I take the name brand!
Synthroid was actually what led me to realize the issues people can have with generics and different manufacturers etc. I had never thought of that before but its a big deal esp as someone who is on seizure meds.
Ahh so high-intensity interval training cardio would be better? I am a weird person who loves cardio and running but willing to move into whatever will help me not take any more drugs!
Bookmarked this comment as well for that article!

I'd be interested to know if they tried you on liothyronine (Cytomel/NP Thyroid) or Armour Thyroid. Blood TSH, T4, or T3 are not always a good measure of thyroid function.
Maybe this isn't your case, but many people who take Synthroid just end up feeling hot, becoming heat intolerant, and/or losing weight without a real increase in energy.
Seizures are often related to metabolism as well. It is theorized that the brain's ability to use glucose for fuel has been compromised, much like what is happening with diabetes.
Yes, occasional high-intensity running will often give many more benefits without the negatives of long-distance.
And don't forget sunlight. Super underutilized.
