Thyroid problems can usually be treated with medication. In some cases, surgery may be necessary.
There are two main types of thyroid hormone: thyroxine (T4) and triiodothyronine (T3). The thyroid gland makes about 80% of its hormone as T4 and about 20% as T3. However, T3 is about four times more active than T4. In other words, the body needs less T3 to do its job than T4.
If you are considering taking iodine supplements, it is important to speak with your healthcare provider first to ensure that they are right for you.
