Abbott Lingo is a over-the-counter (OTC) continuous glucose monitor (CGM) designed for general wellness, helping adults understand how food, exercise, and stress affect their glucose levels to build healthier habits for better energy, focus, and metabolism, without a prescription. It uses a small, water-resistant biosensor worn on the arm for 14 days that sends data to a smartphone app, providing personalized insights, coaching, and challenges to improve overall well-being, based on Abbott's Freestyle Libre technology.
