Our Sources
7,500+ sources.
Every one graded.
We don't scrape the internet. Every source is selected, graded for credibility, and monitored for change.
Authoritative — Regulatory & Reference
The primary record, published by the body responsible for it.
Peer-reviewed — Published Evidence
Literature and guidelines that cleared independent review before publication.
Institutional — Medical Institutions
Patient-facing material from academic medical centres and disease-focused organizations.
Government — Public Health & Payer
Guidance and coverage rules that determine what is available, and to whom.
Community — Patient Experience
Lived experience, always labeled as experiential and never presented as clinical evidence.
Commercial — Manufacturer Programs
Access and affordability information published by manufacturers. Labeled as such, and never the sole basis for an answer.
How We Evaluate Sources
Peer Review Status
Is the information published in peer-reviewed journals or from regulatory bodies with established review processes?
Institutional Authority
Does the source represent a recognized medical institution, government agency, or accredited organization?
Update Frequency
How recently was the information updated? We monitor for changes and flag outdated content automatically.
Conflict of Interest
We assess funding sources and potential biases. Pharmaceutical-sponsored content is clearly labeled.
