I'm not sure how helpful I can be. I was recently diagnosed with hashimotos. My thyroid is still functioning but it is struggling. I was told that whether I start taking thyroid replacement hormones or not, my thyroid will eventually be damaged enough that I will become hypothyroid. I started thyroid replacement now because I am ttc and it might help to have a lower TSH. While there isn't evidence that it will definitely slow down the progression, it can't hurt.

I read that some supplements can help. B6 will help your energy level. Selenium and magnesium supposedly promote healthy thyroid function, though not all endocrinologists agree. My RE says that these supplements won't hurt.

I'm not sure yet if any of this helps. Aside from the blood test, my only symptoms can be explained by other things. Also, I've only been taking these for a few weeks.

Before taking supplements, check the dosage in your multivitamin.
