i cant find the information I read on this again right now so no link, but what I read goes a little like this. Progesterone plays an opposites role to estrogen, and is released in quantity at some point during the period. I imagine that women using an estrogen based supplement would benefit from the added progesterone added at the right time to off set the estrogen count when the body expects it too.

If I can find that info....I will post a link.
