If combining Ashwagandha with DPP-4 inhibitors, monitor fasting and postprandial blood glucose periodically. Watch for hypoglycemia symptoms. Discuss supplementation with your diabetes provider, particularly if HbA1c is near or below target, as dose adjustment may be needed.
Why this interaction occurs
Ashwagandha has demonstrated insulin-sensitizing effects in controlled clinical trials, reducing fasting blood glucose and HbA1c in type 2 diabetic patients. Combined with DPP-4 inhibitors that enhance incretin-mediated insulin secretion, additive glucose reduction may occur, potentially causing hypoglycemia in susceptible individuals.
