Everything Vyvata knows about this product — the score, the evidence, the FAQ, and where else to find shopper reviews. No hidden data. Every vendor is scored on the same published rubric — no brand can pay for placement. Read the rubric →
Black cohosh (Actaea racemosa) has RCT evidence for menopausal vasomotor symptoms — the Remifemin extract (Osmers 2005) showed benefit at 40 mg/day. Hepatotoxicity signal in post-marketing surveillance (Teschke 2010) is a genuine safety concern requiring liver-function awareness. Whole-herb without triterpene standardization delivers uncertain active dose vs Remifemin. Would move to Standard 62+ with named Remifemin extract and prominent hepatotoxicity warning.
The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.
Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.

Strongest: Evidence at 58/100 (quality of published RCT support for the active ingredients at the label dose) and Manufacturing at 58/100 (third-party testing, GMP compliance, and facility audit status). Weakest: Safety at 50/100 (adverse-event profile, interaction risk, and dose ceiling) and Sustainability at 48/100 (sourcing practices, packaging, and corporate practice). All six dimensions feed the overall Vyvata score; a weakness on any one dimension pulls the overall down proportionally.
No third-party certifications (NSF, USP, ConsumerLab, or equivalent) were on record at the time of scoring. This affects the Manufacturing dimension score. The manufacturer may test internally or have obtained certification more recently — check the current product label for the most up-to-date information.
Would move to Standard 62+ with named Remifemin extract and prominent hepatotoxicity warning.
