“Knowing my glucose means no more guessing.
It’s all based on data. My data.” 


– Serena Williams

Thanks to Lingo, Serena’s figured out that staying in a healthy glucose range** isn’t about achieving perfection. It’s about noticing the patterns and habits that support her goals (and the ones that don’t).

Just like Serena, your body is unique. When you get to know your glucose, you gain insights that can help support your metabolic health, now and in the future. 

**A typical glucose range for healthy individuals is 3.9-7.8 mmol/L. Fluctuations beyond 7.8 mmol/L and under 3.9 mmol/L may occur from time to time and are to be expected.

How Lingo works

BiosensorBiosensor
Apply your biosensor

The Lingo biosensor is an over-the-counter (OTC), continuous glucose monitor (CGM). It attaches painlesslyto the back of your upper arm. You won’t even notice it’s there.


‡ In a study conducted by Abbott, 91.6 % of users surveyed (n=119) agree that it was painless to apply the biosensor. Data on file, Abbott.
