How to lower excess estrogen: - Cut alcohol (it switches on aromatase, the enzyme that turns testosterone into estrogen, and it slows the liver's clearance of estrogen. In one study a single drink raised estradiol in women on HRT 3x within an hour, PMID 8940324) - Get body fat under 25% (fat tissue makes its own estrogen through aromatase. A year of diet-driven weight loss cut estradiol 16% and free estradiol 21%, PMID 22614972) - Cut the xenoestrogens you touch every day (plastic food containers, fragranced products, non-stick pans, unfiltered tap water, polyester against sweating skin) - Sunlight, egg yolks and oysters (vitamin D, vitamin E and zinc all turn aromatase down. Active vitamin D cut aromatase expression in fat and breast tissue, PMID 19906814) - 150mg DIM twice a day (pushes estrogen breakdown toward the weak 2-OH form instead of the potent 16-OH form, and raised SHBG in a 12-month placebo-controlled trial, PMID 28560655) - Feed the liver's exit routes: choline from 2 to 3 egg yolks a day, 3g glycine, 100 to 200mg magnesium taurate with dinner (methylation and COMT are how the liver tags estrogen for disposal, and they run on choline, glycine and magnesium) - 200mg calcium D-glucarate with lunch (blocks the gut enzyme that unwraps estrogen the liver already packaged for exit) - 30g of fiber a day plus 1 raw carrot between meals (going from 15g to 30g of fiber dropped estrone and estradiol in 2 months in 62 women, PMID 1652197)
