Why this scored 63/100

Time-released 500 mg ascorbic acid is a reasonable formulation upgrade — vitamin C plasma saturation caps around 200 mg per single dose, so slow release improves total absorption fraction. Rose hips add small natural bioflavonoid content. Would move to Verified 70+ with USP verification and confirmed sustained-release dissolution testing.

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.
