Chromium and Insulin Lispro, a caution.
Chromium can improve glucose handling in some patients with diabetes or insulin resistance. When added to insulin lispro, improved insulin sensitivity may lower insulin requirements and increase hypoglycemia risk if meal doses are unchanged. The risk is highest during the first weeks after starting chromium or when diet, exercise, or weight changes occur at the same time.

Caution
What is happening. Chromium can improve glucose handling in some patients with diabetes or insulin resistance. When added to insulin lispro, improved insulin sensitivity may lower insulin requirements and increase hypoglycemia risk if meal doses are unchanged. The risk is highest during the first weeks after starting chromium or when diet, exercise, or weight changes occur at the same time.
Mechanism. Chromium may potentiate insulin receptor signaling and GLUT4-mediated glucose uptake in insulin-resistant tissues. This can compound insulin lispro's rapid prandial glucose-lowering effect.
Recommendation. Start chromium with insulin lispro only if you can monitor glucose more frequently. Check before meals, 2 hours after meals, and at bedtime for 1-2 weeks, and ask your diabetes clinician whether meal boluses or correction factors need adjustment. Keep fast carbohydrate available.
