Re: Natural Thyroid Hormone
Your MD is ignorant of the composition of natural dessicated thyroid. It's porcine tissue, not bovine. The CDC reports no possibility of transmissible disease from porcine prions.
Your doctor's reasoning is laughable for someone who should be knowledgeable in the field of science.
