Why this scored 50/100
Forever Lean is a weight-management capsule product from Forever Living's MLM lineup, typically formulated around chromium picolinate plus a starch/fat-blocker blend (Phase 2 white-kidney-bean extract, prickly pear). Meta-analyses on chromium for weight loss (Onakpoya 2013) show clinically trivial effect sizes (~1 lb over 12-24 weeks), and starch-blocker evidence is weak and short-duration. The FTC has aggressively targeted MLM weight-loss claims in this category, and the product does not present any RCT-anchored evidence. Held in Rejected by weak evidence, category-typical marketing overreach, and MLM markup on an ineffective formulation. Would move to Standard only with disclosed per-active doses backed by peer-reviewed RCTs.

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.
