I take kelp. You can get in vitamins section at most pharmacies. Morning and then again not too late in the day. When I was pregnant my numbers were lower and they wanted me to go on the drug. I think you are then dependant on the drug for life. I told the veteran nurse no, I will double my kelp, since I am eating for two, you can test me again next month. Next month back for my tests, levels were fine. Nurse said whatever you are doing, keep doing it. Thyroid needs iodine, should be common sense for a nurse but she was baffled. I also purged fluoride and heavy metals (with cilantro & chlorella) before I was able to become pregnant. I think that is very important for thyroid health as well.
