Is Trulicity actually insulin?

Trulicity is not insulin. It's a glucagon-like peptide-1 (GLP-1) receptor agonist. It works by stimulating insulin release in your body when you eat to help lower your blood glucose (sugar) levels. It also lowers the amount of new glucose your liver makes. What's more, Trulicity slows the passage of food through your digestive tract. This helps you feel full sooner after eating, making you eat less. This effect helps regulate blood glucose, and it can also lead to weight loss. View original source
