Over the Counter CGM Options in 2025

Here’s a roundup of the over-the-counter continuous glucose monitors (CGMs) you can get without a prescription, perfect for people tracking blood sugar for wellness, pre-diabetes, or lifestyle insights.

Lingo  
The Lingo CGM from Abbott, marketed as a consumer biowearable,  tracks glucose trends over 14-day sensor periods. Lingo provides real-time insights into how meals and activities influence blood sugar. Lingo is also offers individual sensor units. 

Stelo 
Stelo from Dexcom allows real-time glucose tracking straight and is designed for adults not on insulin who want to understand how food, activity, and sleep affect glucose throughout the day. Stelo sensors typically last about 15 days and give continuous 24/7 data, making it a strong choice for wellness and metabolic insights.

What Makes OTC CGMs Worth Considering in 2025

• No Prescription Needed: Devices like Stelo and Lingo let you buy directly without a doctor’s prescription.
• Wellness & Metabolic Insight: These tools aren’t just for diabetes, they help people optimize diet, activity, sleep, and stress by showing real-time glucose responses. 
• Convenience: Wear the sensor on your arm and view trends easily on your smartphone app, ideal for busy professionals and health-curious users

Things to keep in mind

• OTC CGMs typically don’t include advanced medical alerts (like low-blood-sugar alarms) that prescription devices offer. 
• They’re designed mainly for non-insulin users (Type 2 diabetes, pre-diabetes, metabolic tracking) rather than accurate clinical glycemic control.
