Big effect
A combination supplement cut menopausal somatic symptoms by 54% in a 90-day trial — but the effect can't be pinned on black cohosh alone.
This early, small study suggests a mix of black cohosh, soy isoflavones, and SDG lignans may offer substantial relief from physical menopausal symptoms, but because it tested a blend, we don't know how much credit black cohosh deserves — and the finding needs replication before trusting it broadly.
In a 90-day randomized trial of 90 postmenopausal women, a supplement combining black cohosh, soy isoflavones, and SDG lignans reduced somatic (physical) menopausal symptoms by 54% compared to placebo. However, the study tested a mixture, not black cohosh alone, so the specific contribution of black cohosh is unclear. The results are promising but come from a single small trial, so they should be considered preliminary.
Where this fits in the evidence
This is among the first studies we've indexed on Black Cohosh for Reduced Somatic Symptom Score — treat it as an early signal until more research accumulates.
