Why this scored 35/100
The title lists three legitimate ingredients (Vitamin D3, Vitamin K2, hawthorn fruit) but the listing does not name a brand, and the images are hosted on CJ Dropshipping's CDN — the anonymous white-label supply chain used by cross-border dropshippers. The bodyHtml discloses only a 60ml volume and a 2-year shelf life, no IU/mcg per drop, no MK-7 vs MK-4 form, no hawthorn standardization, and no manufacturer. Hawthorn (Crataegus) has some evidence for mild-to-moderate heart failure symptoms (Pittler 2008 Cochrane) but requires standardization to extract ratio (e.g. WS 1442) and per-dose measurement to be meaningful; a liquid drop with no per-drop dose disclosure cannot be scored positively. Not autofailing on unverified medical claim (no explicit medical claim in the sparse listing), but transparency and formulation gaps put it firmly in Rejected.

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.
