Review:
Thyroid Extract (desiccated Thyroid)
overall review score: 2.5
⭐⭐⭐
score is between 0 and 5
Thyroid extract (desiccated thyroid), also known as desiccated thyroid hormone or Armour Thyroid, is a medication derived from the dried and powdered thyroid glands of animals, typically pigs. It has been used historically to treat hypothyroidism by supplementing deficient thyroid hormones, primarily T4 (thyroxine) and T3 (triiodothyronine). While once common, its use has declined in favor of synthetic thyroid hormone preparations.
