How It Works
The server loads structured evidence data (clinical doses, form comparisons, medication-nutrient interactions) and exposes it through MCP tools. When an AI assistant receives a supplement question, it calls the appropriate tool and gets back formatted, citation-backed recommendations.
Product rankings are based on cost-per-effective-daily-dose, third-party certification status, and clinical evidence — not sponsorship.
