This capsule delivers 540mg of **Black Cohosh** root powder, positioned for menopausal symptom relief — specifically hot flashes and vasomotor symptoms. However, the clinical research (a meta-analysis of 22 RCTs with 2,310 women) used standardized extracts at 20–40mg per day, not raw root powder. You're getting whole root, which is not bioequivalent to the standardized form and has considerably less clinical backing.
The most-studied form is the isopropanolic extract (sold as Remifemin) standardized to 2.5% triterpene glycosides — the compounds believed to drive the benefit. Raw powder at 540mg may contain these compounds, but the concentration is uncontrolled and unstandardized, making it difficult to know your actual active dose.
If you're specifically looking for hot flash relief supported by research, you'd want a standardized extract rather than raw root powder. The evidence on black cohosh is moderate overall — some trials show meaningful improvement, others find no difference from placebo — and the strongest results come from standardized forms this product doesn't use.
