- Manufacturing standards — FDA-registered facility, GMP certification, and third-party testing where available
- Label transparency — specific dosages disclosed, no undisclosed proprietary blends
- Verified customer satisfaction — weighted average from authenticated purchase reviews, not curated testimonials
- Value for money — effective ingredient doses at a fair price, with a meaningful refund guarantee
