Forever Therm is Forever Living's MLM thermogenic weight-loss tablet, typically formulated with green tea extract, caffeine, and green coffee bean extract. Green tea catechins + caffeine show a small thermogenic effect (Hursel 2011 meta-analysis, ~4% increase in daily energy expenditure), but real-world weight-loss effects are clinically small (1-3 lb over 12 weeks) and green coffee bean data (the original Vinson 2012 study) was retracted. The FTC has targeted MLM thermogenic claims aggressively. Held in Rejected by weak effect size, retracted underlying evidence for a common ingredient, and MLM markup. Would move to Standard with honest positioning as a caffeine + green tea catechin supplement and disclosed per-active doses.
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.

Strongest: Manufacturing at 55/100 (third-party testing, GMP compliance, and facility audit status) and Safety at 52/100 (adverse-event profile, interaction risk, and dose ceiling). Weakest: Evidence at 45/100 (quality of published RCT support for the active ingredients at the label dose) and Sustainability at 45/100 (sourcing practices, packaging, and corporate practice). All six dimensions feed the overall Vyvata score; a weakness on any one dimension pulls the overall down proportionally.
No third-party certifications (NSF, USP, ConsumerLab, or equivalent) were on record at the time of scoring. This affects the Manufacturing dimension score. The manufacturer may test internally or have obtained certification more recently — check the current product label for the most up-to-date information.
