A gentler answer to hot flashes: what the isoflavone research really shows.

Hot flashes are the symptom most women want gone first and are most often told to live with. The isoflavone literature is one of the quietest, most consistent stories in menopause medicine.

A 2012 meta-analysis of 19 randomised trials found that soy-derived isoflavones at roughly 50–100 mg per day reduced hot flash frequency by an average of 21% and severity by 26% compared to placebo, without the risks associated with hormone therapy.

The catch is time. Most trials didn't see significant change until week six, and full effect landed around week twelve. This is not a same-day intervention. It's a slow, tissue-level shift.

MenoSync uses standardised soy isoflavones at the studied dose, paired with black cohosh and ashwagandha to address the sleep and mood pieces that hot flashes drag along.
