What are some otc supplements are best to help low thyroid?

Mugwort (Artemisia): Many otc supplements are promoted for treating "low thyroid" (such as l-tyrosine, kelp, forskolin, raw thyroid glandular, mugwort, bitters, bayberry and goldenseal). For a true low thyroid condition, it is essential to measure blood levels of thyroid stimulating hormone (TSH) and thyroid hormones to monitor treatment. Usually prescription thyroid hormone (or thyroid extract) is needed.

Hmm....: Honestly; there may be 'supplements' out there that are supposed to "promote thyroid health" but in my opinion if you have a low thyroid you should have your doctor examine you; you may need true thyroid replacement(e.g. Synthroid, (thyroxine) etc.) and possibly a referral to be evaluated by an endocrinologist.

None: Since thyroid pills are cheap and easy to get they are the most reliable way to replace them (with a prescription). Otc or "natural" thyroid replacements are unreliable. Anyway... Have your thyroid hormones checked. Iodine ( now added to salt) is important to avoid goiters.

Iodine and GTA: Iodine 12-14mg per day and gta forte (glandular thyroid) will both help. Kelp has iodine, xenostat has iodine in micrograms -biotics has iodozyme 6.25mg need 2tabs daily.
