We judge ingredient lists and formulations in context: foods vs. beverages vs. supplements vs. bottled water vs. personal care and home essentials each use their own framework (harmful-ingredient tiers, additive load, cosmetics safety vs. nutrient logic, dosing quality for pills and powders). Notable ingredients are classified for display—from clearly beneficial to clearly harmful—with hard rules where the science is settled (seed oils stay red-flagged; natural caffeine from coffee/tea/etc. isn't treated like a synthetic spike).

We separate simpler, recognizable products from highly engineered formulas. We reward minimally processed goods and penalize ultra-processed options in context for what the product is meant to be.

How a product reaches you can matter when material contacts what you ingest or absorb. Packaging type is detected independently (plastic vs. glass vs. metal, liners, bottled-water formats, steeping tea bags, and similar cases).

We take into account lab testing results, recalls, contaminant overlays, transparency, PFAS disclosures, ethical-brand overlays backed by documented events, and more. Ranking entries flagged “Lab tested” tie to curated third-party quantitative work (Consumer Reports, EWG, Clean Label Project, independent labs such as Valisure-style testing contexts, Mamavation, Detox Project, regulatory action levels where relevant). External signals stay proportionate: not every headline moves the needle equally.
