How We Rank Weight Loss Supplements
Our ranking methodology for weight loss supplements uses five equally weighted criteria:
- Ingredient quality & clinical backing — key actives must have peer-reviewed research supporting their use for weight loss goals at the doses used
- Manufacturing standards and third-party testing where available
- Label transparency — specific dosages disclosed, no undisclosed proprietary blends
- Customer feedback — treated as anecdotal; we don’t publish ratings or review counts we can’t verify
