Known interactions

  • Category rule: glp1 × supplement
    Note

    GLP-1 medications slow stomach emptying, changing how/when oral supplements absorb; rapid weight loss raises the importance of protein and micronutrients.

    Time oral supplements when nausea is lowest; prioritize protein and micronutrients; discuss with your provider.

  • Category rule: supplement × medication
    Note

    Some supplements change how the body processes medications (absorption, liver enzymes, or additive effects).

    Specific pairs are checked against a licensed drug database and shown with their own severity. Always confirm with your provider or pharmacist.
