Chromium and Dulaglutide, a caution.
Dulaglutide is a weekly GLP-1 receptor agonist that lowers glucose by stimulating glucose-dependent insulin secretion and slowing gastric emptying. Chromium improves insulin sensitivity. On dulaglutide alone the hypoglycemia risk is low, but additive effects can produce symptomatic lows when chromium is added to a regimen that also includes insulin or a sulfonylurea.

Caution
What is happening. Dulaglutide is a weekly GLP-1 receptor agonist that lowers glucose by stimulating glucose-dependent insulin secretion and slowing gastric emptying. Chromium improves insulin sensitivity. On dulaglutide alone the hypoglycemia risk is low, but additive effects can produce symptomatic lows when chromium is added to a regimen that also includes insulin or a sulfonylurea.
Mechanism. Dulaglutide activates pancreatic GLP-1 receptors, augmenting glucose-dependent insulin release and suppressing glucagon. Chromium potentiates insulin receptor signaling in skeletal muscle and liver. The two reduce blood glucose by different but complementary mechanisms.
Recommendation. If dulaglutide is your only diabetes medication, chromium can be added with home glucose monitoring for the first 2-4 weeks. If you also take insulin or a sulfonylurea, ask your prescriber whether those agents need to be reduced first.
