Why this scored 58/100
Berberine has strong RCT support for glycemic and lipid endpoints (Yin 2008, Zhang 2010 meta), typically at 500mg 2-3x/day. NYC Herbs is a small brand and per-cap mg isn't clearly disclosed from title. Trial-matching requires 1000-1500mg/day total. GI tolerability concerns (diarrhea, cramping) not surfaced. Would move to Standard 65+ with per-cap mg at clinical range and TID dosing guidance.

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.
