The #1 CGM worldwide¹

FreeStyle Libre 3 is continuous glucose monitoring (CGM) system that streams minute-to-minute glucose readings directly to your patients’ smartphones,^◊◊ enabling patients to act faster to reduce hypoglycaemia.

Unrivaled performance^5,6 your patients can count on

Glucose readings every minute of every hour of every day for up to 15 days

Longest wear time and data storage⁷

Stays on and stores glucose readings for up to 15 days—so your patients just need 2 sensors a month!

Patients can view their minute-to-minute glucose data with a quick glance of their smartphones^◊◊

The small but mighty way to make more informed decisions² that can add up to big changes over time.

Discreet

Smaller than the size of a £1 coin easy to wear⁸ with a discreet sensor for up to 15 days with the Libre 3 Plus sensor, and up to 14 days with the Libre 3 sensor.

Patients simply scan to activate the sensor – no finger pricking^† or code entry is required.

Easy

The sensor is easy to apply⁸ using a one-piece applicator. It requires no in-person training to use.⁸

The sensor can be worn while patients shower, swim and exercise.^T

Optional, escalating alarms⁹ let your patients know the minute glucose is too high or low.

The optional alarms⁹ gradually increase in volume to help your patients know when to take action.

The FreeStyle Libre 3 system streamlines minute-to-minute readings to your patients smartphone and is shown to significantly lower A1c and reduce hypos

Excellent, reliable glucose alarms so your patient's caregivers^11,12 have peace of mind ^9,13

The fully customisable glucose alarms allow users to set high and low glucose alarm thresholds, based on individual needs and preferences. Alarms let patients know the minute they’ve crossed the preset thresholds, allowing them to take action to manage their glucose levels.

Three optional sound/vibration alarms alert patients to:

Low glucose levels 
High glucose levels 
Signal loss

Significant improvement in clinical outcomes² and quality of life¹⁴

95% of patients have a better understanding of their glucose fluctuations²

1hr more Time in Range per
day compared to finger
pricking¹⁰

0.55% reduction of HbA1c at
2-4 months and sustained at
month 12 in adults and
children with T1D and adults
with T2D.¹⁴

NOTE: statistically significant HbA1c reduction based on the confidence interval range.

Studies data collected with FreeStyle Libre system and are applicable to the FreeStyle Libre 3 system based on technological similarities.
