Free · No account · based on published sources including NIH ODS, FDA drug labels, and peer-reviewed literature
Monitor blood glucose if adding Maca to your routine while on insulin. Although evidence is limited, some patients may experience modest changes in glucose levels. Do not adjust insulin doses without consulting your diabetes care team. Report unexpected low or high blood glucose readings.
Why this interaction occurs
Lepidium meyenii (Maca) contains glucosinolates and other phytochemicals that have shown preliminary glucose-modulating activity in animal models and small human studies. The clinical magnitude is uncertain, but given the narrow therapeutic window of insulin therapy, awareness and monitoring are warranted.
Evidence
Evidence level: limited.
