Why this scored 72/100

Solgar (founded 1947, Leonia NJ) is one of the reference US premium vitamin brands — cGMP-certified, no artificial preservatives, single-ingredient product line discipline, and a long track record in professional and retail channels. This product is 100mcg MK-7 (natto-derived) per vegetable capsule — clean, transparent formulation. Natto-derived MK-7 is naturally all-trans, the biologically active isomer. Vegan capsule. Solgar's Gold Standard Isotope-tested products (their premium sub-line) publish testing detail; their standard line does not consistently publish per-lot COAs, which is the main gap between them and Elite-tier peers. The K2 evidence base (Knapen 2015 arterial stiffness, Sato 2020 bone Gla protein, Rotterdam Study observational) supports 100-180mcg MK-7 daily for bone/CV outcomes. Verified tier for the combination of brand track record, honest formulation, and defensible dose.

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.
