Ceylon cinnamon (Cinnamomum verum) 20:1 extract 500mg. Ceylon vs Cassia cinnamon distinction matters — Cassia has high coumarin content (hepatotoxic at high doses), Ceylon is much lower. Real blood-sugar-modulation evidence for cinnamon (Allen 2013 meta-analysis, ~24 mg/dL fasting glucose reduction). Ceylon-specific sourcing is a formulation plus. Held below Verified by (1) NusaPure quality tier without third-party assay (Cassia contamination of 'Ceylon' products is a known issue); (2) cinnamaldehyde standardization not disclosed. Would move to Verified 70+ with third-party botanical-authentication assay + cinnamaldehyde standardization.
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.

Would move to Verified 70+ with third-party botanical-authentication assay + cinnamaldehyde standardization.
Strongest: Safety at 72/100 (adverse-event profile, interaction risk, and dose ceiling) and Formulation at 65/100 (dose adequacy, bioavailability form, and ingredient redundancy). Weakest: Manufacturing at 55/100 (third-party testing, GMP compliance, and facility audit status) and Sustainability at 50/100 (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 Verified 70+ with third-party botanical-authentication assay + cinnamaldehyde standardization.

The Vyvata score measures product integrity against a published rubric, not customer sentiment. Vyvata does not aggregate, republish, or license third-party reviews — the links below open search pages on their respective platforms.
Every VSF-related metafield surfaced verbatim. Nothing hidden. If you spot data that looks wrong, let us know.
Every score is set from the published rubric, audit-logged, and rescored whenever new evidence emerges (published trials, updated labels, third-party testing releases). Every vendor is scored on the same criteria — no pay-to-play. See our editorial-independence disclosure for the full policy, including brands with an editorial relationship to this site.
