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 →
Meriva is an Indena-patented curcumin phytosome bound to soy phosphatidylcholine, with pharmacokinetic data showing ~29x bioavailability of total curcuminoids versus unformulated curcumin (Cuomo 2011) — one of the best-supported turmeric delivery forms in humans. Meriva-based trials include osteoarthritis pain (Belcaro 2010) and inflammatory-marker reductions, so this is a genuinely evidence-backed formulation choice. Swanson's generic curcumin lines don't approach this. Would move to Elite 85+ with a Meriva-standardized curcuminoid mg disclosure on-label plus per-lot third-party testing.
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: Formulation at 82/100 (dose adequacy, bioavailability form, and ingredient redundancy) and Evidence at 80/100 (quality of published RCT support for the active ingredients at the label dose). Weakest: Manufacturing at 72/100 (third-party testing, GMP compliance, and facility audit status) and Sustainability at 62/100 (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.
