Actually I have, and it's always normal but "low normal". I've even had a radioactive dye sort of thyroid test, and again all was normal but low normal. I mean just to make up numbers, if a "normal value" is in the range of 1-5, mine would be something like 1.1. I've read on the internet that people with values like mine - normal but low normal, have benefited from thyroid supplementation.

However I saw multiple doctors, and not one was willing to prescribe meds since my values still fell into the "normal" range. I finally got tired of fighting. One of those frustrations of having to go through a gatekeeper for something you think may benefit your health, only to have the gate slammed in your face.

After a while I got tired of fighting doctors. I don't know, maybe it's time to try again. But I just hate the idea, so keep looking for natural ways to boost thyroid function, and trying to avoid things that suppress the thyroid further.
