Caller: My question is about Dr. Peat’s newsletter on “ Tissue-bound estrogen and aging”: he mentions that menopausal women often get high estrogen concentration in their tissue, as opposed to their blood. Could they get a dose of progesterone to knock it out of their tissue into their blood, and then get a phlebotomy ? Would that help to decrease systemic estrogen ?
RP: No. If the liver is working, and if you’re eating enough protein, and if your thyroid is ok, your liver will send the estrogen straight to your kidneys, to be excreted, as soon as the progesterone gets it out of your cells into the bloodstream.
And there are several enzyme systems involved in this: the progesterone basically destroys the estrogen receptor that binds estrogen. It destroys the enzyme that releases estrogen from the glucuronic form deposited in cells. It activates the enzymes that add the glucuronic acid to remove it from cells. And it shifts the oxidative enzymes, so that they destroy the active form of estrogen. So, everything progesterone does to estrogen system, gets it out of the cells, then your liver will send it to your kidneys to excrete.
HD: And progesterone helps the liver to get rid of excess estrogen as well.
RP: Yeah. Progesterone activates the thyroid to do that.
Nice... thanks @HDD
