Why this scored 40/100
Generic portable sauna box under an unrecognizable "Anti Spier" brand with a five-line description and no manufacturer, model, heater spec, or EMF data. No brand provenance and insufficient safety documentation for a plugged-in heating device.
Auto-fail rule triggered: No brand provenance.
The manufacturer, contract-manufacturing facility, or lab of record cannot be verified from public sources. Prevents Vyvata from assessing GMP compliance, third-party testing history, or quality-control track record. See the full rubric →

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.
