Cassandra,
No, I'm not a rep for any progesterone cream company. Do you assume
everytime a poster mentions a pharmaceutical that they represent the
drug company who sells it? I use this reference because of the
information provided on the site, not because Arbonne sells a product
(which I have never used by the way). The references are to websites,
not email addresses. You are absolutely correct about the other forms
and sources of "natural" progesterone. Any hormone with the same
chemical structure as human progesterone is considered natural
progesterone. As far as I know, all USP progesterone used in OTC or
prescription products is plant derived from wild yam and/or soy.
The question specifically addressed use of progesterone during pregnancy
and that is why I made specific warning against progestins. Progestins,
of any chemical structure, are contraindicated in pregnancy. It's time
and space consuming to repeat all this info about progesterone everytime
I mention it. Hopefully women will do some reading and talk to a
pharmacist or doctor about it.
