Why this scored 54/100
Generic unit-dose blister-pack vitamin D3 at 400 IU — this is the 1997 IOM Adequate Intake, not a level supported by modern serum 25(OH)D data. Endocrine Society (Holick 2011) and most current supplementation trials use 1000–2000 IU/day minimum for repletion, and the VITAL trial (Manson 2019) used 2000 IU. 400 IU rarely moves serum 25(OH)D meaningfully in deficient adults. Anonymous manufacturer with no brand accountability, no third-party testing, and no cofactors (K2, magnesium). Would move to Standard-Verified at 1000–2000 IU with named manufacturer, USP verification, and K2 MK-7 pairing.

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.
