Natural Desiccated Thyroid

overall review score: 4
score is between 0 and 5
Natural desiccated thyroid (NDT) is an organic hormone replacement derived from the thyroid glands of animals, typically pigs. It contains a combination of thyroid hormones, mainly thyroxine (T4) and triiodothyronine (T3), in a natural ratio, and has been used historically to treat hypothyroidism. NDT is often favored by individuals seeking a more 'natural' alternative to synthetic thyroid medications.
