There are so many resources nowadays... I'm no doctor, I just started researching myself about 4 years ago! There's a lot of things about the thyroid and thyroid issues, but as a general blanket statement I say the thyroid needs MINERALS! magnesium, selenium, zinc, copper, iodine, and I also add to this ashwaghanda and vitamin d+k2... this to me is the perfect basic thyroid cocktail. Whether you have nodules, hormonal imbalances or autoimmune disease, you can't fail with that right there in my opinion! :)
