Why this scored 55/100
Thyroid-support blend — typically iodine (kelp), selenium, tyrosine, and adaptogens. Selenium at 200 mcg has evidence for autoimmune thyroiditis (Gärtner 2002). Real safety concern is undisclosed iodine mcg per serving, which can push users on levothyroxine or with autoimmune thyroid conditions out of range. Would move to Standard 60+ with iodine mcg and selenium mcg disclosure, and to Verified 70+ with clear autoimmune / Rx-thyroid contraindications on-label.

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.

Strongest: Formulation at 58/100 (dose adequacy, bioavailability form, and ingredient redundancy) and Manufacturing at 58/100 (third-party testing, GMP compliance, and facility audit status). Weakest: Transparency at 52/100 (dose disclosure vs proprietary blends, and honesty of marketing claims) and Safety at 45/100 (adverse-event profile, interaction risk, and dose ceiling). All six dimensions feed the overall Vyvata score; a weakness on any one dimension pulls the overall down proportionally.
