What CGM Sensor is Right For You?

Managing glucose levels can be confusing, but the right combination of health tech (like continuous glucose monitors (CGMs) or glucose biosensors) and expert guidance can make it easier.
What Are CGM Sensors + Their Benefits
Continuous glucose monitor (CGM) sensors are wearable devices that track glucose 24/7, offering insights into how your body responds to food, activity, and sleep. Unlike traditional finger-pricking methods, CGM sensors continuously monitor your glucose levels, connect to smartphone apps, and can often be linked to third-party health platforms, helping you manage your health in real time.
But with so many options available, how do you pick the CGM that’s the best fit for you?
Finding the Right CGM Sensor for Your Needs
Whether you’re looking for one to prevent or reverse conditions like prediabetes or type 2 diabetes, manage weight loss, optimize your fitness, or check in on your health, there’s a perfect sensor for you.
Nutrisense CGM Solutions
Nutrisense stands out because it can support many CGM sensors and glucose biosensors manufactured by the major market players such as:
- Dexcom G6 & G7
- FreeStyle Libres
- Stelo Glucose Biosensor by Dexcom
Nutrisense also provides value-added features for your CGM or biosensor, including:
- In-depth glucose charts and analytics.

CGMs + Nutritionist Support: The Power Duo You Need

Even if you pick the perfect sensor—what do you do once you have all that data? At Nutrisense, giving you access to sensors that help you view glucose data is just one part of the solution. The real game-changer is the combination of this data with expert nutritionist support.

Using Your CGM Sensor with the Nutrisense Program
If you already have a continuous glucose monitor (CGM) prescribed by your healthcare provider or want to pick your own over-the-counter CGM sensor or glucose biosensor, you can still benefit from the Nutrisense platform. You can integrate a number of compatible sensors with the app to unlock a comprehensive set of tools that go far beyond basic glucose data tracking.
After a FREE 3-day trial, you can connect your CGM to the Nutrisense app for an annual membership fee of $199 ( just $16.58 a month!) or a monthly membership of $19 a month, and enjoy features like:
- Meal logging and scoring to see how your diet impacts glucose levels.
- Activity tracking to correlate exercise and glucose responses.
- Insights on glucose trends and personalized metrics to help you better understand your data over time.
- Your membership also includes the option to work with an expert nutritionist. You can schedule an insurance-covered video call with a glucose-trained registered dietitian or nutritionist to help you turn your data into an actionable health plan.
See the chart below for more on specific sensor and biosensor compatibility. With new sensors often released in the market, we’re constantly innovating to ensure we add newer compatible options so your glucose tracking is smooth and efficient.
Best CGM Sensors — Side-by-Side Comparison
When selecting the right continuous glucose monitor (CGM) or glucose biosensor, aligning the choice with your health goals is important. To get the most out of the sensors, it’s best to work 1:1 with a registered dietitian who specializes in glucose management. For example, here’s a guide to help you find the best fit for your needs:
- Best Biosensor or CGM for Weight Loss: The Dexcom G7 is a good CGM choice if weight loss is your goal but it requires a prescription. An excellent option is the Stelo Glucose Biosensor paired with the Nutrisense program. The glucose tracking, especially when combined with guidance from a dietitian and the Nutrisense App, gives you more than just glucose data—you’ll also receive personalized advice to connect the dots between your diet, activity, and glucose levels.‍
- Best Biosensor or CGM for Athletes: For athletes looking to fine-tune performance, many CGMs offer good tracking. However, to really adjust your fueling strategies during training or competition, the Stelo Glucose Biosensor with the Nutrisense Program is a great option. Expert dietitian support and the Nutrisense App paired with this sensor will give you a holistic view of how your lifestyle impacts your glucose levels.‍
- Best CGM for Prediabetes or Type 2 Diabetes:The FreeStyle Libre 3 and Dexcom G7 are ideal for managing prediabetes or type 2 diabetes. These sensors have options to set up glucose alarms to prevent blood sugar spikes and dips. However, they need a prescription. ‍
- Best Affordable Over-the-Counter option: The Stelo Glucose Biosensor by Dexcom is an affordable OTC glucose biosensor, for in-depth glucose data tracking.
- Best CGM for Type 1 Diabetes: If you have type 1 diabetes, the Medtronic CGM is a strong option. It integrates with insulin pumps, providing continuous glucose data and adjusting insulin delivery in real time.
- Best CGM for Long-Term Use: The implantable Eversense CGM lasts up to six months, and is the go-to option for people who want long-term blood glucose monitoring.
