How we grade evidence

Not all data is equal.
We show our work.

Every ingredient in the Clarity database is assigned an evidence tier based on the quality and origin of its safety data. This is how we hold ourselves accountable — and how you know what to trust.

✓ Gold tier
Cross-referenced with primary clinical sources: LactMed (NIH), InfantRisk, or Hale's Medications & Mothers' Milk. Highest confidence.
Silver tier
Supported by PubMed-indexed peer-reviewed research with PMID citations. Strong evidence, not yet cross-referenced with primary sources.
Bronze tier
Literature-derived from published sources. Clinical review pending. Not yet verified against primary sources.
