9 reports from women who tried Soy Isoflavones
I really wanted Soy Isoflavones to help with my sleep disruption and joint pain but after 12 weeks I saw no meaningful improvement. if anything I felt slightly worse. Not for me, but everyone is different.
I really wanted Soy Isoflavones to help with my heart palpitations and anxiety but after 12 weeks I saw no meaningful improvement. it just wasn't effective for me. Disappointing but at least I know now.
After 10 weeks on Soy Isoflavones, I'd say it made a modest difference to my weight gain and low mood. The change was there but subtle. Not sure if I'll continue long-term.
Unfortunately Soy Isoflavones didn't work for my loss of confidence and low mood. I gave it 10 weeks and the symptoms persisted despite consistent use. I've stopped taking it.
Mixed feelings about Soy Isoflavones. energy improved was noticeable, but the hot flashes continued didn't really improve. I may try increasing the dose.
Research context compiled from published sources
Isoflavones (particularly genistein and daidzein) bind preferentially to oestrogen receptor beta (ERβ) with much lower affinity than oestradiol. This selective binding may produce mild oestrogenic effects in bone, blood vessels, and the brain while having less stimulatory effect on breast and uterine tissue. Equol-producers (women whose gut bacteria convert daidzein to equol) may experience greater benefit.
