Our Data Sources
Check Supplement pulls from the most comprehensive and authoritative sources available. Our analysis combines primary government databases with specialized research tools to ensure you get accurate, up-to-date information.
Primary Clinical Sources
PubMed / NIH
The world's largest database of peer-reviewed medical research. Home to over 36 million citations from biomedical literature.
FDA / OpenFDA
Official U.S. Food & Drug Administration data including adverse event reports, safety alerts, and regulatory information.
Specialized Research Databases
Beyond public sources, we utilize highly specialized databases focused on supplement science, drug-nutrient interactions, and clinical dosing data. These curated resources allow us to provide depth of analysis that goes beyond what's available through standard searches.
Scoring Methodology
Our ingredient and product scores combine evidence quality with practical value. Here's how we weight the factors:
Based on the strength of clinical evidence: meta-analyses and systematic reviews score highest, followed by RCTs, then observational studies.
How broadly relevant is this supplement? Addressing common deficiencies (like Vitamin D or Magnesium) scores higher than niche applications.
Considers reported side effects, drug interactions, and contraindications based on FDA data and clinical literature.
The Deficit Baseline: We recognize that 70%+ of people are deficient in certain nutrients (Magnesium, Vitamin D, Omega-3s). Supplements addressing widespread deficiencies get appropriate recognition for their population-level impact.
