Raw EMF-shielding fabric sold by the foot. Category note: consumer EMF-blocking products are marketed to reduce health effects from RF/wireless radiation, but WHO, FDA, and ICNIRP all conclude non-thermal RF at consumer device levels doesn't have established health effects. The fabric physically blocks RF as advertised (Faraday-cage principle) — that's a real function — but the health-benefit implication behind the product category doesn't have established evidence. Held below Standard by unclear specific use case for raw shielding fabric + health-marketing overhead. This SKU doesn't quite trigger the medical-claim auto-fail because it's sold as raw material rather than a medical-effect product.
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.

Strongest: Safety at 60/100 (adverse-event profile, interaction risk, and dose ceiling) and Formulation at 55/100 (dose adequacy, bioavailability form, and ingredient redundancy). Weakest: Sustainability at 45/100 (sourcing practices, packaging, and corporate practice) and Evidence at 40/100 (quality of published RCT support for the active ingredients at the label dose). All six dimensions feed the overall Vyvata score; a weakness on any one dimension pulls the overall down proportionally.
No third-party certifications (NSF, USP, ConsumerLab, or equivalent) were on record at the time of scoring. This affects the Manufacturing dimension score. The manufacturer may test internally or have obtained certification more recently — check the current product label for the most up-to-date information.

The Vyvata Scoring Framework rates every listed product 0–100 across six dimensions: Evidence, Formulation, Manufacturing, Safety, Transparency, and Sustainability. Tier bands: Elite 85–100 (top-tier evidence + formulation + manufacturing), Verified 70–84 (strong on most dimensions), Standard 50–69 (solid but with weaknesses called out), Rejected 0–49 (specific failures documented). Rejected products remain listed with reasons. Full methodology at https://vyvata.com/pages/methodology.
