For folks with diabetes, continuous glucose monitors (CGM) have revolutionized healthcare. They allow diabetics to monitor their blood sugar levels without constantly finger pricking — instead, they can just check their phone to find out real-time glucose levels. And recently, that technology has gone mainstream. 

Even folks without diabetes can benefit from checking their blood sugars. People with prediabetes or hypoglycemia can better understand the fluctuations in their sugar levels, and CGMs are also used by elite athletes and folks interested in their health and wellness. Just like continuously tracking your heart rate, steps, or sleep, monitoring your glucose levels gives you better insights into your health as a whole. 

CGMs made for non diabetics pierce your skin with tiny filaments covered by a patch, giving you a continuous reading, usually sent to your phone, of glucose levels in your interstitial fluid between skin layers. It gives you an accurate assessment of blood sugar levels, but note that it’s typically delayed by about 15 minutes. 

Some of the following programs encourage you to wear the patch all the time, often for a few months, while other programs have you wear the patch for just a couple weeks at a time so you can learn how certain foods affect you without committing to months of continuous wear. And since the U.S. requires prescriptions for all CGMs, the companies all partner with physicians to take care of the prescription for you.

These monitors help you determine exactly how your eating patterns affect your glucose levels. Maybe certain foods make your blood sugar shoot up more than others — finding that out will help you adjust your eating patterns and feel better. You’ll also find out other triggers that raise your sugars, like dehydration, lack of sleep, stress, and caffeine, or ones that lower your blood sugars like exercise. The monitors are beneficial to anyone experiencing any level of insulin resistance. 

Below, we’ve rounded up five of the best CGMs on the market for non-diabetic folks. While blood sugar monitoring provides you with some major health insights, note that it’s not for everyone. Make sure you talk to your doctor about any blood sugar-related questions or concerns, too, and check with your provider to see if all or part of your CGM can be covered by insurance or HSA payments.
