Thyroid

OUR THYROID IS MADE UP OF ANY COMBINATION OF LIOTHYRONINE (T3) AND LEVOTHYROXINE (T4).  THE THYROID WE MAKE UP IS DERIVED SYNTHETICALLY IN A LAB FROM THE AMINO ACID TYROSINE FROM THE HUMAN BODY.  THIS IS BETTER SUITED TO YOUR BODY THAN SOME OTHERS THAT ARE ACTUALLY DERIVED FROM PIGS OR COWS.
