Six-dimension breakdown
Why this scored 76/100
2000 IU vitamin D3 (cholecalciferol) softgel. D3 has robust RCT support for bone (Bischoff-Ferrari 2009 meta) and 2000 IU sits within the range typically recommended for status maintenance. Cholecalciferol is the correct form. USP Verified — genuinely one of the highest-purity signals available in mainstream retail. Solid Verified: right ingredient, right form, right dose, verified purity.
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.
