Why this scored 44/100
NYC Herbs sells a proprietary 'Liver Health Blend' with no disclosed silymarin standardization, no per-herb mg breakdown, and marketing language leaning heavily on generalized 'liver support' framing rather than the specific hepatoprotective indications (NAFLD ALT/AST reduction, alcoholic-liver support) where silymarin has modest evidence (Cochrane 2007 Rambaldi; Zhong 2019 NAFLD meta-analysis, WMD ~-9 U/L ALT). Proprietary-blend format prevents users from confirming a therapeutic 150-300 mg silymarin dose. Small herbalist brand with no third-party COA visible. Not autofailed on the title alone, but formulation/transparency floor keeps it in Rejected. Would move to Standard 60+ only with per-ingredient mg disclosure and standardization to 80% silymarin at a clinically studied dose.

Evidence & sources
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.
How to read the Evidence dimension
- 80–100: Multiple double-blind RCTs in indexed journals directly testing this product OR the exact ingredients at the exact dose.
- 60–79: Single double-blind RCT + supporting ingredient literature at the studied dose.
- 40–59: Open-label trials + ingredient literature; no product-specific double-blind evidence.
- 20–39: Ingredient literature only; no product-specific trials or trials in predatory venues.
- 0–19: No credible evidence base or unverifiable claims.
