Health questions
We can explain what an ingredient is studied for and how strong the evidence is. We cannot give personal medical advice. If you are pregnant or nursing, take medication or have a medical condition, please talk to your clinician first.
AI agents and partners
Assistants and developers can use our public catalog API, OpenAPI spec and MCP server, described on the agents page. Affiliate, creator and brand partnership inquiries go to the same email address.
