I find high iodine food helps. Seaweed is very high in this. I eat a lot of sushi as the outer layer is seaweed. Also Miso soup with seaweed shards is very good for you and tasty. Hope this helps

unfortunately there are not alot of options that actually work. there are a few natural products that claim to support your thyroid and they could be worth giving a go. otherwise start on a vitamin d supplement and you need to increase your intake of iodine (iodised salts or even a supplement might help) look into iodine as I believe there has been a study recently done on the impacts of increasing iodine and thyroid function. goodluck from a thyroid suffer
