FAQ
- How does Vyvata rank the best sleep tracking wearables supplements?
- Every product in the Sleep Tracking Wearables subcategory is scored on six dimensions — Evidence, Formulation, Manufacturing, Safety, Transparency, and Sustainability — using the same published rubric. Overall score is 0–100. Products at 70+ are Verified, 50–69 are Standard, and below 50 are Rejected. All 13 scored products in this subcategory are listed on this page with their scores visible, including the ones that failed.
- Why does Vyvata list rejected products instead of hiding them?
- Transparency-first policy: hiding the failures would make the rankings look better than they are. Every rejected product stays listed with the specific reason it failed — proprietary blend hiding dose, sub-therapeutic amount, unverified disease claim, no manufacturer provenance, or misleading naming. Users see the honest picture, not a curated highlight reel.
- Is the top-ranked product (Withings ScanWatch 2 Smart Watch, 38mm, Black HWA10-MODEL 1-ALL-INT) actually the best for me?
- The Vyvata score measures product integrity against the rubric — evidence quality, dose transparency, manufacturing standards. It does not account for your individual health goals, medications, allergies, or existing regimen. The highest-scoring product is the one with the strongest evidence and cleanest formulation in its subcategory; whether it fits your situation is a separate question. Use the Score Yourself flow or talk to a practitioner for individualized guidance.
- How often are these rankings updated?
- Rankings regenerate whenever the underlying catalog changes — new products are scored on import, existing products are rescored when new evidence emerges (published trials, updated labels, third-party testing results). Every score has a "last scored" timestamp on the product page.
- Does Vyvata make money from these rankings?
- Vyvata sells the products it scores. To keep scores honest, the scoring process is separated from merchandising: scores are set from the published rubric and audit-logged, and Vyvata's own house-brand products (Igniton line) are scored on the same criteria as third-party vendors — several of them landed in Rejected or low-Standard tiers as a result. The methodology page documents every rule.
