Why this scored 32/100
This is a fingertip pulse oximeter — a device that measures peripheral capillary oxygen saturation (SpO2) via infrared/red-light absorption spectroscopy. Pulse oximeters are FDA-regulated as Class II medical devices when marketed for clinical use, with 510(k) clearance required. Consumer-grade pulse oximeters from established brands (Masimo MightySat, Nonin Onyx, Zacurate, iHealth) have varying degrees of FDA clearance and independent validation. This SKU is a no-brand LK89 model from a CJ Dropshipping supplier with no FDA 510(k) disclosed, no ISO 13485 disclosed, no independent accuracy validation, and no manufacturer identification. Additionally, this batch is scored as supplements — a pulse oximeter is a wearable/diagnostic device outside the supplement category. If evaluated under the Cat 1 Wearables rubric, it would autofail on 'uncleared medical diagnosis claim' (measures a clinical biomarker without FDA clearance). Rejected at 32 under unverified_medical_claim (the device claims to measure a clinical parameter without regulatory clearance).

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.
