'Bioidentical hormones' are precise duplicates of hormones such as estradiol E2, estriol E3, estrone E1, progesterone, dehydroepiandrosterone, testosterone and levothyroxine as synthesized by the human ovary, adrenal and thyroid.
What is the difference between bioidentical and synthetic HRT?
Bioidentical hormones (such as estradiol, estriol and progesterone) have the same molecular structure as the hormones made by your body. Synthetic hormones (such as Premarin and Provera) do not have the same molecular structure as the hormones in your body, but your body converts them to a usable form.
