Why this scored 45/100

Bitter orange (Citrus aurantium) delivers synephrine, a beta-adrenergic agonist that emerged as an ephedra replacement after ephedra's 2004 ban. Human evidence for weight loss is thin, and cardiovascular case reports (ischemic stroke, arrhythmia, MI — Bouchard 2005, Nasir 2004) are documented especially in combination with caffeine or in individuals with baseline cardiovascular risk. This label discloses no CV cautions, no synephrine mg, and no drug-interaction warnings. Would move to Standard 55+ only with explicit CV contraindication, caffeine-interaction disclosure, and synephrine % standardization.

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.
