Why this scored 45/100
Muscle Faktor's Keto Thrive discloses one ingredient by name (calcium citrate) and explicitly labels the rest as 'proprietary blend.' Under the Zero-Assumption Rule and proprietary_blend_hides_dose autofail rule, undisclosed multi-ingredient formulations forfeit tier eligibility regardless of how well-formulated they might be. The 'keto' positioning implies exogenous ketones (BHB salts) or MCTs as the likely undisclosed content, but without disclosure a reviewer cannot verify. Calcium citrate at supplement doses (typically 200-500 mg per capsule) is a legitimate calcium form; on its own it does not support a 'keto' claim. Rejected on the proprietary blend and the mismatch between the 'keto' branding and the only disclosed ingredient (calcium).
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.
