5x faster readings4

5x faster alarms4

Significant improvement in clinical outcomes5


The FreeStyle Libre 3 system has a MARD below 8%

  • 7.8% Overall MARD2

  • 93.4% Within ± 20% / ± 1.1 mmol/L2

    Percentage of readings within ± 1.1 mmol/L of YSI values for glucose levels < 3.9 mmol/L and ± 20% when ≥ 3.9 mmol/L.

  • 99.9% in Zones A and B of Consensus Error Grid6

5x faster readings


5x faster alarms

In the example comparison below, the patient's glucose is dropping at 0.2 mmol/L per minute and their low glucose alarm is set at 3.9 mmol/L.

Reduced hypoglycaemia

Reduces time spent in hypoglycaemia7 and improves overall glucose control6

  • HbA1c reduction of 0.55% at 2 to 4 months and sustained for 12 months5

  • 95% patients report a better understanding of their glucose fluctuations8

  • 38% reduction in time spent in hypoglycaemia without increasing HbA1c7

  • 40% reduction in nocturnal hypoglycaemia7

  • 50% reduction in serious hypoglycaemia (≤3.0 mmol/L)7

Reduce time spent in hypoglycaemia and improve overall glucose control

How it works

Advanced technology designed to fit into your patients' lives

The FreeStyle Libre 3 system is made up of the FreeStyle Libre 3 sensor and the FreeStyle Libre 3 app.◊◊

The world’s smallest, thinnest9, and most discreet6 glucose sensor

The sensor is worn on the back of the upper arm and continuously measures the glucose concentration in the body's interstitial fluid day and night.

FreeStyle Libre 3 sensor

Scan to activate the sensor – no finger pricking or code entry required

Glucose readings every minute of every day for up to 14 days

14-day sensor data storage means no data gaps

Optional, individually controlled glucose alarms^

Learn about glucose alarms on the FreeStyle Libre 3 App page.

FreeStyle Libre 3 App

Minute-to-minute glucose readings sent to your patients' smartphones every minute◊◊

Patients can interpret the glucose data from the FreeStyle Libre 3 sensor on their smartphone anytime, anywhere to help them make more informed diabetes management decisions.

Prescribing guidance

For all adults with Type 1 diabetes (T1DM)10

NICE guidelines now support the use of the FreeStyle Libre 3 system (rtCGM11) in all adults aged 18 and over with T1DM.10

Healthcare professional advising patient

If your patient is an adult with Type 2 diabetes (T2D MDI),12  the FreeStyle Libre 2 system might be right for them

NICE guidelines support the use of FreeStyle Libre 2 system in selected adults with type 2 diabetes on MDI.13


NICE now recommends HCL

for managing glucose levels in type 1 diabetes16,17,18

This means more Type 1 patients qualify for Hybrid Closed Loop compatible systems like the FreeStyle Libre 3 sensor, which is authrosied to work with the mylife Loop14  system.

FreeStyle Libre 3 App

The FreeStyle Libre 3 app◊◊ allows patients to interpret their glucose data from the FreeStyle Libre 3 sensor on their smartphone anytime, anywhere.



LibreView,our secure15 cloud-based system, allows patients to share their glucose data with Healthcare Professionals. When connected, you will be able to access more in-depth reports to support you in making treatment decisions for your patients.



Patients who use the FreeStyle Libre 3 app◊◊ can remotely share their glucose readings with their caregivers and loved ones through the LibreLinkUp app.§

mylife Loop AID System

The FreeStyle Libre 3 system is now authorised to work with the mylife Loop14 AID system for easier diabetes management and improved glycaemic control for your patients.
