How it was tested: Reductions in mean daily hot flash count at 12 weeks were similar across Promensil (5.1), Rimostil (5.4), and placebo (5.0); neither supplement had a clinically important effect on hot flashes.

Plant compounds that weakly mimic oestrogen, meant to offset the drop that triggers flushes.

Dose: 40–82 mg

Tested as: standardized red clover extracts - Promensil (82 mg/day total isoflavones) and Rimostil (57 mg/day) in the largest trial; an earlier, smaller trial used Promensil 80 mg/day.
