Why this scored 66/100

Standard-of-market milk thistle SKU at 80% silymarin standardization — the concentration used in most European clinical hepatology trials (Loguercio 2012 for NAFLD; Rambaldi 2005 Cochrane on alcoholic/viral liver disease). Named percentage in the title is a genuine transparency strength for a Swanson SKU. Held to top of Standard rather than Verified because plain 80% silymarin still has ~10% oral bioavailability without a phytosome carrier. Would move to Verified 70+ with Siliphos or Silybin phytosome upgrade.

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.
