How This Site Works
Evidence first, marketing never.
Every entry is graded
Approved medicine, clinical-stage, preclinical, or minimal evidence — the tier tells you what kind of data exists before you read a word of claims.
Claims link to evidence
Substantive statements link to PubMed, ClinicalTrials.gov, and regulator labels. Marketing material is never a source.
Named authors, dated reviews
Content is written by Dr. Elena Marsh (PhD) and medically reviewed by Dr. James Okafor (MD), with last-reviewed dates on every entry.
