Why this scored 42/100

NusaPure Sarsaparilla Root 20:1 Extract at 150 mg per capsule. Sarsaparilla (Smilax spp.) is a traditional herb with a long history of medicinal use for skin conditions, syphilis (historically), and 'blood purification.' Modern RCT evidence for supplementation is essentially absent — the literature is dominated by in vitro sarsaponin studies and traditional-use accounts. PubMed searches for Smilax clinical trials in humans return few methodologically-adequate studies of Smilax-only interventions for the marketed indications. The 150 mg 20:1 extract dose (implying 3 g raw equivalent) is also low relative to traditional use (typical tincture or decoction preparations were consumed in larger quantities). Not a safety-based rejection — sarsaparilla is generally well-tolerated. Rejected on evidence and dose grounds.

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.
