We assess whether brands conduct independent lab testing, publish certificates of analysis, and whether their products consistently match label claims. This is the most critical factor for supplement quality.
We evaluate how openly brands source and document their ingredients, whether they use proprietary blends (red flag), and whether they disclose supplier origins and manufacturing standards.
We weigh price against ingredient quality, dosages, and real-world effectiveness based on verified customer reviews and scientific literature. Does the price match the actual value delivered?
