For people like me who have no thyroid gland at all, or are very Hypothyroid, the drugs of choice are Levothyroxine, Levothroid, Thyrolar, and Synthroid. These are Thyroid Syntesizing Hormones. Some natural alternatives for people who still have their thyroid, but it is not producing enough hormones, are L-Tyrosine (500mg 2Xday), and Atlantic Sea Kelp (150-200mg per day) These can be obtained from a homeopathic physician and are in fact prescription medications. Even with natural alternative meds, you will still need to have regular blood TSH level taken to monitor progress. Armour® Thyroid is also often prescribed by Homeopathic and natureopathic physician because it is derived from a living source, mostly pigs, and not a synthetic hormone like Levothyroxine, and Synthroid.

So which hormone you take really comes down to the choice of the patient, and what works best for you.

Yes, levathyroxin sodium, synthroid, .levoxyl , levothroid and unuthroid. You have to work with your DR. for the right one for you.
