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.

Scored against the Vyvata Scoring Framework — an independent 6-dimension rubric applied uniformly to every product. Rejected products remain listed on Vyvata with their scores and reasons visible, as a matter of transparency policy.
