Hi all,
Not only are the ginsenosides chemically structurally similar to the estrogen molecule, there's also evidence of those effects in both sexes (and across different species), with potential mechanisms including both elevating estrogen levels[1][2] and activating the receptor[3][4] directly.
The effects might be mild—especially if taken only intermittently, but that defeats the purpose of an effective, daily adaptogen doesn't it?
Rhodiola[1] likely also falls into the pro-estrogen bucket, showing moderate success in alleviating menopause symptoms.
Ginkgo has mixed results[1][2][3][4][5] but is probably best shied away from on a daily basis.
Soy is another hotly contested one especially amongst vegans, but again (in extreme quantities) I've read literature on feminizing effects. It both activates receptors and raises ligand levels[1][2]. Genistein and daidzein (isoflavones) likely explain these effects[3],and—besides bacon—soy is the predominant food source. The role in breast cancer is double-edged and an open area of research[4].
Icariin in horny goat weed (you can similarly search this up) has suspected estrogenic effects.
Most mushrooms—including probably lion's mane[1]—act as weak-to-low aromatase inhibitors. So they should slow your conversion of testosterone into estrogen. Though women have more of this enzyme, a high mushroom diet is not recommended in postmenopausal syndrome; once the ovaries cease to produce estrogen, aromatization becomes the primary source.
Green tea should be mostly anti-estrogenic, although it also decreases testosterone overall[1][2][3][4].
Ginger is probably the most studied androgenic herb[1][2].
I recently found two new supplements also, Calcium D-Glucarate[1] and (dose-dependently) DIM[2][3]. They both regulate or affect estrogen metabolism, and DIM occurs naturally in leafy greens and other foods.
These supplements can also be taken by women with ovarian or breast cancer remission/risk, or who are just looking to regulate their hormone levels naturally. The effect on serum parameters is mild, only a 20% increase or decrease
Happy experimenting!
And don't be afraid to quit taking a supplement that isn't agreeing with you
Opening this up to further discussion.
