Thyroid Hormone replacement therapy

Thyroid hormone supplementation involves a dose of 0.5 to 3 grain of triiodothyronine ( T3) and thyroxine (T4), most commonly found in the form of Amour Thyroid, an easily available and inexpensive prescription medication. This form of thyroid replacement, as opposed to a synthetic thyroid hormone that provides only T4, is usually the most effective, because it supplies both essential components of the thyroid hormone. Selenium is required to convert T4 to T3. Supplying T4 alone can result in inefficient T3 production because of depleted selenium levels in many individuals. Also, some people have a genetic condition that binds T4 to protein and prevents the successful generation o f T3.
