Fertility & CycleMenopause Support

Overview

Acts on dopamine receptors to lower prolactin, which is why it is studied for luteal-phase support, cycle regularity and PMS. Typical doses are 20-40 mg of standardised extract each morning; give it three cycles. Can interact with dopaminergic medication and hormonal birth control.

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.
