What CGM Sensor is Right For You?
Managing glucose levels can be confusing, but the right combination of health tech (like continuous glucose monitors, or CGMs) 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.

Using Your CGM Sensor with the Nutrisense Program

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.
