overall review score: 4
score is between 0 and 5
Natural Desiccated Thyroid (NDT) is an animal-derived hormone replacement therapy used to treat hypothyroidism. It is made from dried and powdered thyroid glands of animals, typically pigs, and contains a combination of active thyroid hormones including T3 (triiodothyronine) and T4 (thyroxine). NDT has been used for decades as an alternative to synthetic thyroid medications, offering a more 'natural' option that some patients prefer due to its balanced hormone profile.
