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.
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.

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.
