Continuous Glucose Monitors (CGMs)
Continuous glucose monitors used to be diabetes-only medical hardware. In 2026 they are an over-the-counter metabolic-health tool, a small sensor on your upper arm streaming glucose data to an app every minute, so you can see exactly what your breakfast, your stress level, or your sleep did to your blood sugar.
Five consumer programs dominate the US market. They all use Abbott or Dexcom sensor hardware underneath; the difference is in the app, the coaching, and the price.

Frequently asked questions
Do I need a prescription for a CGM in the US?
No. As of 2024 the FDA cleared both Stelo (Dexcom) and Lingo (Abbott) as over-the-counter CGMs for adults who do not use insulin. Levels, Nutrisense, and Veri are direct-to-consumer programs that ship compatible sensors without a traditional prescription visit.
What's the difference between Levels, Nutrisense, and Lingo?
Levels is app + sensors, no coaching, lowest monthly cost. Nutrisense is app + sensors + 1:1 dietitian coaching, highest cost. Lingo is the cheapest pure hardware option (no coaching, no software ecosystem), best if you already know what to do with the data.
How long do CGM sensors last?
Abbott Libre sensors (used by Levels, Nutrisense, Lingo) last 14 days. Dexcom G7 / Stelo sensors last 15 days. After that you peel it off and apply a new one.
Is wearing a CGM if I am not diabetic actually useful?
The honest answer: useful for 2-4 weeks, then diminishing returns. You learn how your specific body reacts to specific foods, sleep, exercise, and stress, and that knowledge is permanent. Wearing one indefinitely as a healthy adult is more about behavior reinforcement than new information.
