Chromium and Insulin Aspart, a caution.
Chromium can improve glucose and insulin responses in some people with diabetes or insulin resistance. Added to insulin aspart, this may reduce insulin needs and increase the risk of hypoglycemia if meal doses are not adjusted. The risk is most relevant when chromium is started at high doses, diet changes at the same time, or glucose is already tightly controlled.

Caution
What is happening. Chromium can improve glucose and insulin responses in some people with diabetes or insulin resistance. Added to insulin aspart, this may reduce insulin needs and increase the risk of hypoglycemia if meal doses are not adjusted. The risk is most relevant when chromium is started at high doses, diet changes at the same time, or glucose is already tightly controlled.
Mechanism. Chromium may enhance insulin receptor signaling and improve peripheral glucose uptake in insulin-resistant states. This can add to insulin aspart's rapid stimulation of glucose uptake and suppression of hepatic glucose output after meals.
Recommendation. If you use insulin aspart, start chromium only with more frequent glucose checks. Monitor before meals, 2 hours after meals, and at bedtime for 1-2 weeks, and ask your diabetes clinician whether insulin-to-carbohydrate ratios or correction doses should change. Treat glucose below 70 mg/dL promptly.
