Continuous Glucose Monitor

Shop on Amazon

Wear a glucose sensor on the arm that measures blood sugar about every 5 minutes, typically for around 14 days per device and often used for a short learning phase of roughly 30 days. It helps you see how specific foods, sleep, stress, and other behaviors affect your glucose in real time, so you can identify your personal spike triggers and make more effective behavior changes.
