Can anyone who understands the role of estrogen in milk supply explain it to me? I have a 7 week old and supplementing with donor milk. After doing a LOT of research, I'm confused... On the one hand, I've read that estrogen (in excess) limits your milk suppy - which is why people with estrogen dominance may have problems, as can women taking estrogen-based contraceptives. On the other hand, half of the stuff I'm taking for low supply seems to contain phytoestrogens! Alfalfa is estrogenic, as is Fenugreek I believe, and a handful of the other herbs commonly recommended. (So are some other greens I believe, which many report increase supply...)
If phytoestrogens are what we want to increase supply, then should I go straight to the strongest one I know - soy? And if they harm supply, why am I eating all this alfalfa??
