"Calorie Burner Formula" fails Vyvata on three independent grounds: (1) "calorie burner" is a fat-loss claim that no supplement has demonstrated at the outcome level (measurable body composition change) with any reliability — the weight-loss supplement category has the highest gap between marketing claim and RCT-substantiated effect of any supplement subcategory; (2) "Formula" hides a proprietary blend without per-active dose disclosure; (3) common ingredients in this category (green tea EGCG, caffeine, yohimbine, synephrine, guarana) have well-documented safety risks at higher doses (cardiovascular events with yohimbine and synephrine, hepatotoxicity with high-dose green tea extract per USP alert). Auto-failed under unverified_medical_claim for the fat-loss positioning and would additionally trip proprietary_blend_hides_dose.
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.

The Vyvata score measures product integrity against a published rubric, not customer sentiment. Vyvata does not aggregate, republish, or license third-party reviews — the links below open search pages on their respective platforms.
Every VSF-related metafield surfaced verbatim. Nothing hidden. If you spot data that looks wrong, let us know.
Every score is set from the published rubric, audit-logged, and rescored whenever new evidence emerges (published trials, updated labels, third-party testing releases). Every vendor is scored on the same criteria — no pay-to-play. See our editorial-independence disclosure for the full policy, including brands with an editorial relationship to this site.
