# Comparing Dexcom G6 and Freestyle Libre: Which Continuous Glucose Monitoring System is Right for You?
## Introduction:
[Continuous Glucose Monitoring systems](https://cgmmonitors.com/) (CGMs) are a game-changer for people living with diabetes. They help monitor glucose levels in real-time and provide real-time insulin dosing decisions, leading to improved glucose control. In this article, we will compare two popular CGMs, the Dexcom G6 and Freestyle Libre, to help you decide which one is right for you.
### Dexcom G6:
The Dexcom G6 is a small and discreet wearable device that continuously monitors glucose levels. It is inserted under the skin and transmits readings to a compatible smart device every five minutes. The G6 is also water-resistant, making it ideal for people who lead active lifestyles.
#### Freestyle Libre:
The Freestyle Libre is a small, disposable, and discreet sensor that is attached to the skin. It provides glucose readings by scanning the sensor with a reader device or smartphone. Unlike the G6, the Freestyle Libre does not transmit readings in real-time, but it provides glucose readings at a touch of a button.

#### Accuracy:
Both the Dexcom G6 and Freestyle Libre have shown excellent accuracy in clinical trials. The Dexcom G6 has a mean absolute difference (MAD) of 9.3 mg/dL, while the Freestyle Libre has a MAD of 9.4 mg/dL. The slight difference in accuracy is not significant and both devices provide accurate glucose readings.

#### Ease of Use:
The Dexcom G6 is considered easier to use than the Freestyle Libre, as it provides real-time readings without the need for a reader device. The Freestyle Libre, on the other hand, requires scanning with a reader device or smartphone, which some users may find cumbersome.

#### Cost:
The cost of continuous glucose monitoring systems can be a significant barrier for some people. The Dexcom G6 is typically more expensive than the Freestyle Libre, as it requires a monthly subscription fee for the continuous transmission of glucose readings. The Freestyle Libre, on the other hand, is a one-time purchase and does not require a subscription fee.

#### Freestyle Libre 3:
The Libre 3 is the latest version of the Freestyle Libre and is [now available]([/](https://cgmmonitors.com/product/freestyle-libre-3-sensor/)) for purchase online. It offers improved accuracy, a longer battery life, and a more compact design than its predecessor. The Freestyle Libre 3 also includes real-time glucose readings, making it a more convenient option for users.

##### Conclusion:
Both the Dexcom G6 and Freestyle Libre are excellent continuous glucose monitoring systems that provide accurate and reliable glucose readings. The Dexcom G6 is ideal for those who want real-time glucose readings without the need for a reader device. The Freestyle Libre is a cost-effective option for those who do not require real-time readings and prefer a one-time purchase. The Freestyle Libre 3 is the latest and most advanced version of the Freestyle Libre, offering improved accuracy and real-time readings. Ultimately, the choice between these two systems will depend on personal preferences and needs.
