Why this scored 38/100
'JUST LOSE IT' is a classic sports-nutrition fat-burner marketed on outcome ('lose it') rather than mechanism or verifiable dose. Products in this category near-uniformly rely on proprietary stimulant blends (caffeine + yohimbine + green tea extract + rauwolscine + synephrine + capsaicin combinations) where individual ingredient doses are hidden behind a 'thermogenic blend' or 'fat-loss matrix' total. That configuration auto-fails Vyvata under proprietary_blend_hides_dose because a reader cannot verify whether the stimulant load is safe, whether individual ingredients are at studied efficacious doses, or whether the product duplicates whatever caffeine the user is already consuming. Compounding that, the product name itself makes a weight-loss claim that no OTC capsule can substantiate at the standard the FTC requires for weight-loss marketing. The Grind is a small brand with limited public quality documentation (no NSF/USP seals, no per-lot COA publication verified). Not listable in current form.

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.
