Why this scored 76/100

[Rescored via evidence crawl] Previous score 72 → new 76. Evidence found: Mortensen SA et al. Q-SYMBIO trial: CoQ10 in chronic heart failure. JACC Heart Fail. 2014;2(6):641-649.. Rationale: Standard Doctor's Best CoQ10 120 mg. Same ingredient class as the 100 mg softgel variant with slightly higher per-capsule dose. Uplift to 76. Note the small 30-count bottle (1-month supply) makes this more of a trial/starter pack.

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.
