BACKGROUND : As defined by the Dietary Supplement Health and Education Act 1997, such substances as herbs and dietary supplements fall under general Food and Drug Administration supervision but have not been closely regulated to date.Surprisingly, nine out of ten supplements showed detectable amounts of T3, ranging from 1.3 mcg to 25.4 mcg per tablet. Taken at the recommended dosage, five of the ten supplements delivered T3 quantities in excess of 10 mcg/day, and four delivered T4 quantities ranging from 8.57 to 91.6 mcg/day.

The researchers concluded that most of the OTC thyroid supplements that were studied contained clinically-significant amounts of T4 and T3, in some cases doses that exceed typical prescribed amounts being used for thyroid hormone replacement treatement.Results: The amount of T4 and T3 was measured separately for each supplement sample. Nine out of 10 supplements revealed a detectable amount of T3 ( g/tablet) and 5 of 10 contained T4 ( g/tablet).
