Can I Take chromium and metformin Together?

SUMMARY:

Taking chromium supplements together with metformin may increase the blood-glucose–lowering effect and could raise the risk of low blood sugar; blood glucose should be monitored and any symptoms reported to a clinician.

ADDITIONAL NOTES:

Chromium is a micronutrient that can improve insulin sensitivity; when used alongside antidiabetic medication (metformin) there is a potential for additive glucose-lowering effect and rare hypoglycemia. Watch for symptoms of low blood sugar (dizziness, sweating, shaking, confusion), check blood glucose more frequently when starting or changing chromium dose, and consult the prescriber before changing doses. People with kidney problems should seek medical advice before starting supplements.
