How We Rank
Products are ranked by safety score (0–100), which considers UL exceedance, unsupported health claims, and proprietary blend disclosure. Products with equal safety scores are then sorted by evidence coverage — the percentage of ingredients backed by Tier-A or Tier-B research.
Safety scores are computed from product label data (DSLD) cross-referenced with 0 research sources. See our Editorial Policy for full methodology.
