Isoflavone Supplements for Menopausal Women: A Systematic Review
Nutrients (2019) · Systematic review
We found that isoflavones reduce hot flashes even accounting for placebo effect, attenuate lumbar spine bone mineral density (BMD) loss, show beneficial effects on systolic blood pressure during early menopause, and improve glycemic control in vitro.
The trials behind this curve used 40 to 82 mg of isoflavones a day. A meta-analysis of five trials at that range found a marginal fall of 1.5 hot flushes a day (PMID 17239573). A second meta-analysis of eight trials found a larger effect in the subgroup taking 80 mg or more (PMID 33920485), and a meta-analysis of Promensil at 80 mg found 3.6 fewer hot flushes a day (PMID 28160855). A 6-month RCT at 80 mg improved Menopause Rating Scale scores (PMID 39254422). No cited trial reports 40 mg on its own or tested more than about 80 mg, so no threshold, optimal dose or safety ceiling is plotted.
