Once configured, ask your AI assistant:

• "What is the evidence for biotin and hair loss?"
• "Search for melatonin supplements and sleep research"
• "Find PubMed papers about ashwagandha and anxiety from 2023"
• "What ingredients are in the vitamins category?"
• "Get details about PMID 12345678"
• "What health conditions does CITED Health cover?"
