Why this scored 56/100
Windmill Health Products is a legacy vitamin brand (founded 1963, NJ) — one of the older pharmacy-shelf mid-tier lines. The listing text is very sparse — it does not disclose D3 IU per tablet, K2 mcg per tablet, MK-4 vs MK-7 form, or any COA data. Windmill products are typically formulated at conservative middle-of-the-road doses and manufactured at cGMP facilities. The lack of on-listing dose disclosure is the biggest concern — a K2+D3 buyer should be able to see IU/mcg and MK-form before purchase. Standard tier based on brand track record; would move higher with per-serving dose transparency and any third-party COA publication.

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.
