FAQ
- How does Vyvata rank the best nutrient deficiency testing supplements?
- Every product in the Nutrient Deficiency Testing 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 4 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. Every vendor is scored on the same rubric — no pay-to-play.
- Is the top-ranked product (Vitamin/Mineral Tests for B12, Magnesium, Iron and Methylfolate) 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 every vendor is scored on the same criteria regardless of commercial relationship. See the site FAQ's editorial-independence disclosure for the full policy. The methodology page documents every scoring rule.
